+ * - `raw` (Boolean) - do raw deflate
+ * - `gzip` (Boolean) - create gzip wrapper
+ * - `to` (String) - if equal to 'string', then result will be "binary string"

+   Decode literal, length, and distance codes and write out the resulting
+   literal and match bytes until either not enough input or output is
+   available, an end-of-block is encountered, or a data error is encountered.
+   When large enough input and output buffers are supplied to inflate(), for
+   example, a 16K input buffer and a 64K output buffer, more than 95% of the
+   inflate execution time is spent in this routine.
+
+   Entry assumptions:
+
+        state.mode === LEN
+        strm.avail_in >= 6
+        strm.avail_out >= 258
+        start >= strm.avail_out
+        state.bits < 8
+
+   On return, state.mode is one of:
+
+        LEN -- ran out of enough output space or enough available input
+        TYPE -- reached end of block code, inflate() to interpret next block
+        BAD -- error in block data
+
+   Notes:
+
+    - The maximum input bits used by a length/distance pair is 15 bits for the
+      length code, 5 bits for the length extra, 15 bits for the distance code,
+      and 13 bits for the distance extra.  This totals 48 bits, or six bytes.
+      Therefore if strm.avail_in >= 6, then there is enough input to avoid
+      checking for available input while decoding.
+
+    - The maximum bytes that a single length/distance pair can output is 258
+      bytes, which is the maximum length that can be coded.  inflate_fast()
+      requires strm.avail_out >= 258 for each loop to avoid checking for
+      output space.

+   Process a set of code lengths to create a canonical Huffman code.  The

+   for codes with equal lengths.  Then the code starts with all zero bits
+   for the first code of the shortest length, and the codes are integer
+   increments for the same length, and zeros are appended as the length
+   increases.  For the deflate format, these bits are stored backwards
+   from their more natural integer increment ordering, and so when the
+   decoding tables are built in the large loop below, the integer codes
+   are incremented backwards.
+
+   This routine assumes, but does not check, that all of the entries in
+   lens[] are in the range 0..MAXBITS.  The caller must assure this.
+   1..MAXBITS is interpreted as that code length.  zero means that that
+   symbol does not occur in this code.
+
+   The codes are sorted by computing a count of codes for each length,
+   creating from that a table of starting indices for each length in the
+   sorted table, and then entering the symbols in order in the sorted
+   table.  The sorted table is work[], with that space being provided by
+   the caller.
+
+   The length counts are used for other purposes as well, i.e. finding
+   the minimum and maximum length codes, determining if there are any
+   codes at all, checking for a valid set of lengths, and looking ahead
+   at length counts to determine sub-table sizes when building the

-V. General Format of a .ZIP file
---------------------------------
-
-  Files stored in arbitrary order.  Large .ZIP files can span multiple
-  volumes or be split into user-defined segment sizes. All values
-  are stored in little-endian byte order unless otherwise specified. 
-
-  Overall .ZIP file format:
-
-    [local file header 1]
-    [file data 1]
-    [data descriptor 1]
-    . 
-    .
-    .
-    [local file header n]
-    [file data n]
-    [data descriptor n]
-    [archive decryption header] 
-    [archive extra data record] 
-    [central directory]
-    [zip64 end of central directory record]
-    [zip64 end of central directory locator] 
-    [end of central directory record]
-
-
-  A.  Local file header:
-
-        local file header signature     4 bytes  (0x04034b50)
-        version needed to extract       2 bytes
-        general purpose bit flag        2 bytes
-        compression method              2 bytes
-        last mod file time              2 bytes
-        last mod file date              2 bytes
-        crc-32                          4 bytes
-        compressed size                 4 bytes
-        uncompressed size               4 bytes
-        file name length                2 bytes
-        extra field length              2 bytes
-
-        file name (variable size)
-        extra field (variable size)
-
-  B.  File data
-
-      Immediately following the local header for a file
-      is the compressed or stored data for the file. 
-      The series of [local file header][file data][data
-      descriptor] repeats for each file in the .ZIP archive. 
-
-  C.  Data descriptor:
-
-        crc-32                          4 bytes
-        compressed size                 4 bytes
-        uncompressed size               4 bytes
-
-      This descriptor exists only if bit 3 of the general
-      purpose bit flag is set (see below).  It is byte aligned
-      and immediately follows the last byte of compressed data.
-      This descriptor is used only when it was not possible to
-      seek in the output .ZIP file, e.g., when the output .ZIP file
-      was standard output or a non-seekable device.  For ZIP64(tm) format
-      archives, the compressed and uncompressed sizes are 8 bytes each.
-
-      When compressing files, compressed and uncompressed sizes 
-      should be stored in ZIP64 format (as 8 byte values) when a 
-      files size exceeds 0xFFFFFFFF.   However ZIP64 format may be 
-      used regardless of the size of a file.  When extracting, if 
-      the zip64 extended information extra field is present for 
-      the file the compressed and uncompressed sizes will be 8
-      byte values.  
-
-      Although not originally assigned a signature, the value 
-      0x08074b50 has commonly been adopted as a signature value 
-      for the data descriptor record.  Implementers should be 
-      aware that ZIP files may be encountered with or without this 
-      signature marking data descriptors and should account for
-      either case when reading ZIP files to ensure compatibility.
-      When writing ZIP files, it is recommended to include the
-      signature value marking the data descriptor record.  When
-      the signature is used, the fields currently defined for
-      the data descriptor record will immediately follow the
-      signature.
-
-      An extensible data descriptor will be released in a future
-      version of this APPNOTE.  This new record is intended to
-      resolve conflicts with the use of this record going forward,
-      and to provide better support for streamed file processing.
-
-      When the Central Directory Encryption method is used, the data
-      descriptor record is not required, but may be used.  If present,
-      and bit 3 of the general purpose bit field is set to indicate
-      its presence, the values in fields of the data descriptor
-      record should be set to binary zeros.
-
-  D.  Archive decryption header:  
-
-      The Archive Decryption Header is introduced in version 6.2
-      of the ZIP format specification.  This record exists in support
-      of the Central Directory Encryption Feature implemented as part of 
-      the Strong Encryption Specification as described in this document.
-      When the Central Directory Structure is encrypted, this decryption
-      header will precede the encrypted data segment.  The encrypted
-      data segment will consist of the Archive extra data record (if
-      present) and the encrypted Central Directory Structure data.
-      The format of this data record is identical to the Decryption
-      header record preceding compressed file data.  If the central 
-      directory structure is encrypted, the location of the start of
-      this data record is determined using the Start of Central Directory
-      field in the Zip64 End of Central Directory record.  Refer to the 
-      section on the Strong Encryption Specification for information
-      on the fields used in the Archive Decryption Header record.
-
-
-  E.  Archive extra data record: 
-
-        archive extra data signature    4 bytes  (0x08064b50)
-        extra field length              4 bytes
-        extra field data                (variable size)
-
-      The Archive Extra Data Record is introduced in version 6.2
-      of the ZIP format specification.  This record exists in support
-      of the Central Directory Encryption Feature implemented as part of 
-      the Strong Encryption Specification as described in this document.
-      When present, this record immediately precedes the central 
-      directory data structure.  The size of this data record will be
-      included in the Size of the Central Directory field in the
-      End of Central Directory record.  If the central directory structure
-      is compressed, but not encrypted, the location of the start of
-      this data record is determined using the Start of Central Directory
-      field in the Zip64 End of Central Directory record.  
-
-
-  F.  Central directory structure:
-
-      [file header 1]
-      .
-      .
-      . 
-      [file header n]
-      [digital signature] 
-
-      File header:
-
-        central file header signature   4 bytes  (0x02014b50)
-        version made by                 2 bytes
-        version needed to extract       2 bytes
-        general purpose bit flag        2 bytes
-        compression method              2 bytes
-        last mod file time              2 bytes
-        last mod file date              2 bytes
-        crc-32                          4 bytes
-        compressed size                 4 bytes
-        uncompressed size               4 bytes
-        file name length                2 bytes
-        extra field length              2 bytes
-        file comment length             2 bytes
-        disk number start               2 bytes
-        internal file attributes        2 bytes
-        external file attributes        4 bytes
-        relative offset of local header 4 bytes
-
-        file name (variable size)
-        extra field (variable size)
-        file comment (variable size)
-
-      Digital signature:
-
-        header signature                4 bytes  (0x05054b50)
-        size of data                    2 bytes
-        signature data (variable size)
-
-      With the introduction of the Central Directory Encryption 
-      feature in version 6.2 of this specification, the Central 
-      Directory Structure may be stored both compressed and encrypted. 
-      Although not required, it is assumed when encrypting the
-      Central Directory Structure, that it will be compressed
-      for greater storage efficiency.  Information on the
-      Central Directory Encryption feature can be found in the section
-      describing the Strong Encryption Specification. The Digital 
-      Signature record will be neither compressed nor encrypted.
-
-  G.  Zip64 end of central directory record
-
-        zip64 end of central dir 
-        signature                       4 bytes  (0x06064b50)
-        size of zip64 end of central
-        directory record                8 bytes
-        version made by                 2 bytes
-        version needed to extract       2 bytes
-        number of this disk             4 bytes
-        number of the disk with the 
-        start of the central directory  4 bytes
-        total number of entries in the
-        central directory on this disk  8 bytes
-        total number of entries in the
-        central directory               8 bytes
-        size of the central directory   8 bytes
-        offset of start of central
-        directory with respect to
-        the starting disk number        8 bytes
-        zip64 extensible data sector    (variable size)
-
-        The value stored into the "size of zip64 end of central
-        directory record" should be the size of the remaining
-        record and should not include the leading 12 bytes.
-  
-        Size = SizeOfFixedFields + SizeOfVariableData - 12.
-
-        The above record structure defines Version 1 of the 
-        zip64 end of central directory record. Version 1 was 
-        implemented in versions of this specification preceding 
-        6.2 in support of the ZIP64 large file feature. The 
-        introduction of the Central Directory Encryption feature 
-        implemented in version 6.2 as part of the Strong Encryption 
-        Specification defines Version 2 of this record structure. 
-        Refer to the section describing the Strong Encryption 
-        Specification for details on the version 2 format for 
-        this record.
-
-        Special purpose data may reside in the zip64 extensible data
-        sector field following either a V1 or V2 version of this
-        record.  To ensure identification of this special purpose data
-        it must include an identifying header block consisting of the
-        following:
-
-           Header ID  -  2 bytes
-           Data Size  -  4 bytes
-
-        The Header ID field indicates the type of data that is in the 
-        data block that follows.
-
-        Data Size identifies the number of bytes that follow for this
-        data block type.
-
-        Multiple special purpose data blocks may be present, but each
-        must be preceded by a Header ID and Data Size field.  Current
-        mappings of Header ID values supported in this field are as
-        defined in APPENDIX C.
-
-  H.  Zip64 end of central directory locator
-
-        zip64 end of central dir locator 
-        signature                       4 bytes  (0x07064b50)
-        number of the disk with the
-        start of the zip64 end of 
-        central directory               4 bytes
-        relative offset of the zip64
-        end of central directory record 8 bytes
-        total number of disks           4 bytes
-        
-  I.  End of central directory record:
-
-        end of central dir signature    4 bytes  (0x06054b50)
-        number of this disk             2 bytes
-        number of the disk with the
-        start of the central directory  2 bytes
-        total number of entries in the
-        central directory on this disk  2 bytes
-        total number of entries in
-        the central directory           2 bytes
-        size of the central directory   4 bytes
-        offset of start of central
-        directory with respect to
-        the starting disk number        4 bytes
-        .ZIP file comment length        2 bytes
-        .ZIP file comment       (variable size)
-
-  J.  Explanation of fields:
-
-      version made by (2 bytes)
-
-          The upper byte indicates the compatibility of the file
-          attribute information.  If the external file attributes 
-          are compatible with MS-DOS and can be read by PKZIP for 
-          DOS version 2.04g then this value will be zero.  If these 
-          attributes are not compatible, then this value will 
-          identify the host system on which the attributes are 
-          compatible.  Software can use this information to determine
-          the line record format for text files etc.  The current
-          mappings are:
-
-          0 - MS-DOS and OS/2 (FAT / VFAT / FAT32 file systems)
-          1 - Amiga                     2 - OpenVMS
-          3 - UNIX                      4 - VM/CMS
-          5 - Atari ST                  6 - OS/2 H.P.F.S.
-          7 - Macintosh                 8 - Z-System
-          9 - CP/M                     10 - Windows NTFS
-         11 - MVS (OS/390 - Z/OS)      12 - VSE
-         13 - Acorn Risc               14 - VFAT
-         15 - alternate MVS            16 - BeOS
-         17 - Tandem                   18 - OS/400
-         19 - OS/X (Darwin)            20 thru 255 - unused
-
-          The lower byte indicates the ZIP specification version 
-          (the version of this document) supported by the software 
-          used to encode the file.  The value/10 indicates the major 
-          version number, and the value mod 10 is the minor version 
-          number.  
-
-      version needed to extract (2 bytes)
-
-          The minimum supported ZIP specification version needed to 
-          extract the file, mapped as above.  This value is based on 
-          the specific format features a ZIP program must support to 
-          be able to extract the file.  If multiple features are
-          applied to a file, the minimum version should be set to the 
-          feature having the highest value. New features or feature 
-          changes affecting the published format specification will be 
-          implemented using higher version numbers than the last 
-          published value to avoid conflict.
-
-          Current minimum feature versions are as defined below:
-
-          1.0 - Default value
-          1.1 - File is a volume label
-          2.0 - File is a folder (directory)
-          2.0 - File is compressed using Deflate compression
-          2.0 - File is encrypted using traditional PKWARE encryption
-          2.1 - File is compressed using Deflate64(tm)
-          2.5 - File is compressed using PKWARE DCL Implode 
-          2.7 - File is a patch data set 
-          4.5 - File uses ZIP64 format extensions
-          4.6 - File is compressed using BZIP2 compression*
-          5.0 - File is encrypted using DES
-          5.0 - File is encrypted using 3DES
-          5.0 - File is encrypted using original RC2 encryption
-          5.0 - File is encrypted using RC4 encryption
-          5.1 - File is encrypted using AES encryption
-          5.1 - File is encrypted using corrected RC2 encryption**
-          5.2 - File is encrypted using corrected RC2-64 encryption**
-          6.1 - File is encrypted using non-OAEP key wrapping***
-          6.2 - Central directory encryption
-          6.3 - File is compressed using LZMA
-          6.3 - File is compressed using PPMd+
-          6.3 - File is encrypted using Blowfish
-          6.3 - File is encrypted using Twofish
-
-
-          * Early 7.x (pre-7.2) versions of PKZIP incorrectly set the
-          version needed to extract for BZIP2 compression to be 50
-          when it should have been 46.
-
-          ** Refer to the section on Strong Encryption Specification
-          for additional information regarding RC2 corrections.
-
-          *** Certificate encryption using non-OAEP key wrapping is the
-          intended mode of operation for all versions beginning with 6.1.
-          Support for OAEP key wrapping should only be used for
-          backward compatibility when sending ZIP files to be opened by
-          versions of PKZIP older than 6.1 (5.0 or 6.0).
-
-          + Files compressed using PPMd should set the version
-          needed to extract field to 6.3, however, not all ZIP 
-          programs enforce this and may be unable to decompress 
-          data files compressed using PPMd if this value is set.
-
-          When using ZIP64 extensions, the corresponding value in the
-          zip64 end of central directory record should also be set.  
-          This field should be set appropriately to indicate whether 
-          Version 1 or Version 2 format is in use. 
-
-      general purpose bit flag: (2 bytes)
-
-          Bit 0: If set, indicates that the file is encrypted.
-
-          (For Method 6 - Imploding)
-          Bit 1: If the compression method used was type 6,
-                 Imploding, then this bit, if set, indicates
-                 an 8K sliding dictionary was used.  If clear,
-                 then a 4K sliding dictionary was used.
-          Bit 2: If the compression method used was type 6,
-                 Imploding, then this bit, if set, indicates
-                 3 Shannon-Fano trees were used to encode the
-                 sliding dictionary output.  If clear, then 2
-                 Shannon-Fano trees were used.
-
-          (For Methods 8 and 9 - Deflating)
-          Bit 2  Bit 1
-            0      0    Normal (-en) compression option was used.
-            0      1    Maximum (-exx/-ex) compression option was used.
-            1      0    Fast (-ef) compression option was used.
-            1      1    Super Fast (-es) compression option was used.
-
-          (For Method 14 - LZMA)
-          Bit 1: If the compression method used was type 14,
-                 LZMA, then this bit, if set, indicates
-                 an end-of-stream (EOS) marker is used to
-                 mark the end of the compressed data stream.
-                 If clear, then an EOS marker is not present
-                 and the compressed data size must be known
-                 to extract.
-
-          Note:  Bits 1 and 2 are undefined if the compression
-                 method is any other.
-
-          Bit 3: If this bit is set, the fields crc-32, compressed 
-                 size and uncompressed size are set to zero in the 
-                 local header.  The correct values are put in the 
-                 data descriptor immediately following the compressed
-                 data.  (Note: PKZIP version 2.04g for DOS only 
-                 recognizes this bit for method 8 compression, newer 
-                 versions of PKZIP recognize this bit for any 
-                 compression method.)
-
-          Bit 4: Reserved for use with method 8, for enhanced

-
-      date and time fields: (2 bytes each)
-
-          The date and time are encoded in standard MS-DOS format.
-          If input came from standard input, the date and time are
-          those at which compression was started for this data. 
-          If encrypting the central directory and general purpose bit 
-          flag 13 is set indicating masking, the value stored in the 
-          Local Header will be zero. 
-
-      CRC-32: (4 bytes)
-
-          The CRC-32 algorithm was generously contributed by
-          David Schwaderer and can be found in his excellent
-          book "C Programmers Guide to NetBIOS" published by
-          Howard W. Sams & Co. Inc.  The 'magic number' for
-          the CRC is 0xdebb20e3.  The proper CRC pre and post
-          conditioning is used, meaning that the CRC register
-          is pre-conditioned with all ones (a starting value
-          of 0xffffffff) and the value is post-conditioned by
-          taking the one's complement of the CRC residual.
-          If bit 3 of the general purpose flag is set, this
-          field is set to zero in the local header and the correct
-          value is put in the data descriptor and in the central
-          directory. When encrypting the central directory, if the
-          local header is not in ZIP64 format and general purpose 
-          bit flag 13 is set indicating masking, the value stored 
-          in the Local Header will be zero. 
-
-      compressed size: (4 bytes)
-      uncompressed size: (4 bytes)
-
-          The size of the file compressed and uncompressed,
-          respectively.  When a decryption header is present it will
-          be placed in front of the file data and the value of the
-          compressed file size will include the bytes of the decryption
-          header.  If bit 3 of the general purpose bit flag is set, 
-          these fields are set to zero in the local header and the 
-          correct values are put in the data descriptor and
-          in the central directory.  If an archive is in ZIP64 format
-          and the value in this field is 0xFFFFFFFF, the size will be
-          in the corresponding 8 byte ZIP64 extended information 
-          extra field.  When encrypting the central directory, if the
-          local header is not in ZIP64 format and general purpose bit 
-          flag 13 is set indicating masking, the value stored for the 
-          uncompressed size in the Local Header will be zero. 
-
-      file name length: (2 bytes)
-      extra field length: (2 bytes)
-      file comment length: (2 bytes)
-
-          The length of the file name, extra field, and comment
-          fields respectively.  The combined length of any
-          directory record and these three fields should not
-          generally exceed 65,535 bytes.  If input came from standard
-          input, the file name length is set to zero.  
-
-      disk number start: (2 bytes)
-
-          The number of the disk on which this file begins.  If an 
-          archive is in ZIP64 format and the value in this field is 
-          0xFFFF, the size will be in the corresponding 4 byte zip64 
-          extended information extra field.
-
-      internal file attributes: (2 bytes)
-
-          Bits 1 and 2 are reserved for use by PKWARE.
-
-          The lowest bit of this field indicates, if set, that
-          the file is apparently an ASCII or text file.  If not
-          set, that the file apparently contains binary data.
-          The remaining bits are unused in version 1.0.
-
-          The 0x0002 bit of this field indicates, if set, that a 
-          4 byte variable record length control field precedes each 
-          logical record indicating the length of the record. The 
-          record length control field is stored in little-endian byte
-          order.  This flag is independent of text control characters, 
-          and if used in conjunction with text data, includes any 
-          control characters in the total length of the record. This 
-          value is provided for mainframe data transfer support.
-
-      external file attributes: (4 bytes)
-
-          The mapping of the external attributes is
-          host-system dependent (see 'version made by').  For
-          MS-DOS, the low order byte is the MS-DOS directory
-          attribute byte.  If input came from standard input, this
-          field is set to zero.
-
-      relative offset of local header: (4 bytes)
-
-          This is the offset from the start of the first disk on
-          which this file appears, to where the local header should
-          be found.  If an archive is in ZIP64 format and the value
-          in this field is 0xFFFFFFFF, the size will be in the 
-          corresponding 8 byte zip64 extended information extra field.
-
-      file name: (Variable)
-
-          The name of the file, with optional relative path.
-          The path stored should not contain a drive or
-          device letter, or a leading slash.  All slashes
-          should be forward slashes '/' as opposed to
-          backwards slashes '\' for compatibility with Amiga
-          and UNIX file systems etc.  If input came from standard
-          input, there is no file name field.  If encrypting
-          the central directory and general purpose bit flag 13 is set 
-          indicating masking, the file name stored in the Local Header 
-          will not be the actual file name.  A masking value consisting 
-          of a unique hexadecimal value will be stored.  This value will 
-          be sequentially incremented for each file in the archive. See
-          the section on the Strong Encryption Specification for details 
-          on retrieving the encrypted file name. 
-
-      extra field: (Variable)
-
-          This is for expansion.  If additional information
-          needs to be stored for special needs or for specific 
-          platforms, it should be stored here.  Earlier versions 
-          of the software can then safely skip this file, and 
-          find the next file or header.  This field will be 0 
-          length in version 1.0.
-
-          In order to allow different programs and different types
-          of information to be stored in the 'extra' field in .ZIP
-          files, the following structure should be used for all
-          programs storing data in this field:
-
-          header1+data1 + header2+data2 . . .
-
-          Each header should consist of:
-
-            Header ID - 2 bytes
-            Data Size - 2 bytes
-
-          Note: all fields stored in Intel low-byte/high-byte order.
-
-          The Header ID field indicates the type of data that is in
-          the following data block.
-
-          Header ID's of 0 thru 31 are reserved for use by PKWARE.
-          The remaining ID's can be used by third party vendors for
-          proprietary usage.
-
-          The current Header ID mappings defined by PKWARE are:

-          Detailed descriptions of Extra Fields defined by third 
-          party mappings will be documented as information on
-          these data structures is made available to PKWARE.  
-          PKWARE does not guarantee the accuracy of any published
-          third party data.
-
-          The Data Size field indicates the size of the following
-          data block. Programs can use this value to skip to the
-          next header block, passing over any data blocks that are
-          not of interest.
-
-          Note: As stated above, the size of the entire .ZIP file
-                header, including the file name, comment, and extra
-                field should not exceed 64K in size.
-
-          In case two different programs should appropriate the same
-          Header ID value, it is strongly recommended that each
-          program place a unique signature of at least two bytes in
-          size (and preferably 4 bytes or bigger) at the start of
-          each data area.  Every program should verify that its
-          unique signature is present, in addition to the Header ID
-          value being correct, before assuming that it is a block of
-          known type.
-
-         -Zip64 Extended Information Extra Field (0x0001):
-
-          The following is the layout of the zip64 extended 
-          information "extra" block. If one of the size or
-          offset fields in the Local or Central directory
-          record is too small to hold the required data,
-          a Zip64 extended information record is created.
-          The order of the fields in the zip64 extended 
-          information record is fixed, but the fields will
-          only appear if the corresponding Local or Central
-          directory record field is set to 0xFFFF or 0xFFFFFFFF.
-
-          Note: all fields stored in Intel low-byte/high-byte order.
-
-          Value      Size       Description
-          -----      ----       -----------
-  (ZIP64) 0x0001     2 bytes    Tag for this "extra" block type
-          Size       2 bytes    Size of this "extra" block
-          Original

-          Offset     8 bytes    Offset of local header record
-          Disk Start
-          Number     4 bytes    Number of the disk on which
-                                this file starts 
-
-          This entry in the Local header must include BOTH original
-          and compressed file size fields. If encrypting the 
-          central directory and bit 13 of the general purpose bit
-          flag is set indicating masking, the value stored in the
-          Local Header for the original file size will be zero.

-          (var)       variable      Compressed block
-
-          The OS/2 extended attribute structure (FEA2LIST) is 
-          compressed and then stored in it's entirety within this 
-          structure.  There will only ever be one "block" of data in 
-          VarFields[].

-         -NTFS Extra Field (0x000a):
-
-          The following is the layout of the NTFS attributes 
-          "extra" block. (Note: At this time the Mtime, Atime
-          and Ctime values may be used on any WIN32 system.)

-          Rules:
-
-          1. There will be one or more of attributes present, which 
-             will each be preceded by the above TagX & SizeX values.  
-             These values are identical to the ATR$C_XXXX and 
-             ATR$S_XXXX constants which are defined in ATR.H under 
-             OpenVMS C.  Neither of these values will ever be zero.
-
-          2. No word alignment or padding is performed.
-
-          3. A well-behaved PKZIP/OpenVMS program should never produce
-             more than one sub-block with the same TagX value.  Also,
-             there will never be more than one "extra" block of type
-             0x000c in a particular directory record.

-         -UNIX Extra Field (0x000d):
-
-          The following is the layout of the UNIX "extra" block.
-          Note: all fields are stored in Intel low-byte/high-byte 
-          order.
-
-          Value       Size          Description
-          -----       ----          -----------
-  (UNIX)  0x000d      2 bytes       Tag for this "extra" block type
-          TSize       2 bytes       Size for the following data block
-          Atime       4 bytes       File last access time
-          Mtime       4 bytes       File last modification time

-          Gid         2 bytes       File group ID
-          (var)       variable      Variable length data field
-
-          The variable length data field will contain file type 
-          specific data.  Currently the only values allowed are
-          the original "linked to" file names for hard or symbolic 
-          links, and the major and minor device node numbers for
-          character and block device nodes.  Since device nodes
-          cannot be either symbolic or hard links, only one set of
-          variable length data is stored.  Link files will have the
-          name of the original file stored.  This name is NOT NULL
-          terminated.  Its size can be determined by checking TSize -
-          12.  Device entries will have eight bytes stored as two 4
-          byte entries (in little endian format).  The first entry
-          will be the major device number, and the second the minor
-          device number.

-         -FWKCS MD5 Extra Field (0x4b46):
-
-          The FWKCS Contents_Signature System, used in
-          automatically identifying files independent of file name,
-          optionally adds and uses an extra field to support the
-          rapid creation of an enhanced contents_signature:
-
-              Header ID = 0x4b46
-              Data Size = 0x0013
-              Preface   = 'M','D','5'
-              followed by 16 bytes containing the uncompressed file's
-              128_bit MD5 hash(1), low byte first.
-
-          When FWKCS revises a .ZIP file central directory to add
-          this extra field for a file, it also replaces the
-          central directory entry for that file's uncompressed
-          file length with a measured value.
-
-          FWKCS provides an option to strip this extra field, if
-          present, from a .ZIP file central directory. In adding
-          this extra field, FWKCS preserves .ZIP file Authenticity
-          Verification; if stripping this extra field, FWKCS
-          preserves all versions of AV through PKZIP version 2.04g.

-          The ComCRC32 is the standard zip CRC32 checksum of the File Comment

-          was created.  This can happen if a utility changes the File Comment 
-          field but does not update the UTF-8 Comment extra field.  If the CRC 
-          check fails, this Unicode Comment extra field should be ignored and 
-          the File Comment field in the header should be used instead.
-
-          The UnicodeCom field is the UTF-8 version of the File Comment field
-          in the header.  As UnicodeCom is defined to be UTF-8, no UTF-8 byte
-          order mark (BOM) is used.  The length of this field is determined by
-          subtracting the size of the previous fields from TSize.  If both the

-          Flag, bit 11 (Language encoding flag (EFS)), can be used to indicate
-          both the header File Name and Comment fields are UTF-8 and, in this
-          case, the Unicode Path and Unicode Comment extra fields are not
-          needed and should not be created.  Note that, for backward
-          compatibility, bit 11 should only be used if the native character set
-          of the paths and comments being zipped up are already in UTF-8. It is
-          expected that the same file comment storage method, either general
-          purpose bit 11 or extra fields, be used in both the Local and Central
-          Directory Header for a file.

-  K.  Splitting and Spanning ZIP files
-
-          Spanning is the process of segmenting a ZIP file across 
-          multiple removable media. This support has typically only 
-          been provided for DOS formatted floppy diskettes. 
-
-          File splitting is a newer derivative of spanning.  
-          Splitting follows the same segmentation process as
-          spanning, however, it does not require writing each
-          segment to a unique removable medium and instead supports
-          placing all pieces onto local or non-removable locations
-          such as file systems, local drives, folders, etc...
-
-          A key difference between spanned and split ZIP files is
-          that all pieces of a spanned ZIP file have the same name.  
-          Since each piece is written to a separate volume, no name 
-          collisions occur and each segment can reuse the original 
-          .ZIP file name given to the archive.
-
-          Sequence ordering for DOS spanned archives uses the DOS 
-          volume label to determine segment numbers.  Volume labels
-          for each segment are written using the form PKBACK#xxx, 
-          where xxx is the segment number written as a decimal 
-          value from 001 - nnn.
-
-          Split ZIP files are typically written to the same location
-          and are subject to name collisions if the spanned name
-          format is used since each segment will reside on the same 
-          drive. To avoid name collisions, split archives are named 
-          as follows.
-
-          Segment 1   = filename.z01
-          Segment n-1 = filename.z(n-1)
-          Segment n   = filename.zip
-
-          The .ZIP extension is used on the last segment to support
-          quickly reading the central directory.  The segment number
-          n should be a decimal value.
-
-          Spanned ZIP files may be PKSFX Self-extracting ZIP files.
-          PKSFX files may also be split, however, in this case
-          the first segment must be named filename.exe.  The first
-          segment of a split PKSFX archive must be large enough to
-          include the entire executable program.
-
-          Capacities for split archives are as follows.
-
-          Maximum number of segments = 4,294,967,295 - 1
-          Maximum .ZIP segment size = 4,294,967,295 bytes
-          Minimum segment size = 64K
-          Maximum PKSFX segment size = 2,147,483,647 bytes
-          
-          Segment sizes may be different however by convention, all 
-          segment sizes should be the same with the exception of the 
-          last, which may be smaller.  Local and central directory 
-          header records must never be split across a segment boundary. 
-          When writing a header record, if the number of bytes remaining 
-          within a segment is less than the size of the header record,
-          end the current segment and write the header at the start
-          of the next segment.  The central directory may span segment
-          boundaries, but no single record in the central directory
-          should be split across segments.
-
-          Spanned/Split archives created using PKZIP for Windows
-          (V2.50 or greater), PKZIP Command Line (V2.50 or greater),
-          or PKZIP Explorer will include a special spanning 
-          signature as the first 4 bytes of the first segment of
-          the archive.  This signature (0x08074b50) will be 
-          followed immediately by the local header signature for
-          the first file in the archive.  
-
-          A special spanning marker may also appear in spanned/split 
-          archives if the spanning or splitting process starts but 
-          only requires one segment.  In this case the 0x08074b50 
-          signature will be replaced with the temporary spanning 
-          marker signature of 0x30304b50.  Split archives can
-          only be uncompressed by other versions of PKZIP that
-          know how to create a split archive.
-
-          The signature value 0x08074b50 is also used by some
-          ZIP implementations as a marker for the Data Descriptor 
-          record.  Conflict in this alternate assignment can be
-          avoided by ensuring the position of the signature
-          within the ZIP file to determine the use for which it
-          is intended.  
-
-  L.  General notes:
-
-      1)  All fields unless otherwise noted are unsigned and stored
-          in Intel low-byte:high-byte, low-word:high-word order.
-
-      2)  String fields are not null terminated, since the
-          length is given explicitly.
-
-      3)  The entries in the central directory may not necessarily
-          be in the same order that files appear in the .ZIP file.
-
-      4)  If one of the fields in the end of central directory
-          record is too small to hold required data, the field
-          should be set to -1 (0xFFFF or 0xFFFFFFFF) and the
-          ZIP64 format record should be created.
-
-      5)  The end of central directory record and the
-          Zip64 end of central directory locator record must
-          reside on the same disk when splitting or spanning
-          an archive.

-VI. Explanation of compression methods
---------------------------------------
-
-UnShrinking - Method 1
-----------------------
-
-Shrinking is a Dynamic Ziv-Lempel-Welch compression algorithm
-with partial clearing.  The initial code size is 9 bits, and
-the maximum code size is 13 bits.  Shrinking differs from
-conventional Dynamic Ziv-Lempel-Welch implementations in several
-respects:
-
-1)  The code size is controlled by the compressor, and is not
-    automatically increased when codes larger than the current
-    code size are created (but not necessarily used).  When
-    the decompressor encounters the code sequence 256
-    (decimal) followed by 1, it should increase the code size
-    read from the input stream to the next bit size.  No
-    blocking of the codes is performed, so the next code at
-    the increased size should be read from the input stream
-    immediately after where the previous code at the smaller
-    bit size was read.  Again, the decompressor should not
-    increase the code size used until the sequence 256,1 is
-    encountered.
-
-2)  When the table becomes full, total clearing is not
-    performed.  Rather, when the compressor emits the code
-    sequence 256,2 (decimal), the decompressor should clear
-    all leaf nodes from the Ziv-Lempel tree, and continue to
-    use the current code size.  The nodes that are cleared
-    from the Ziv-Lempel tree are then re-used, with the lowest
-    code value re-used first, and the highest code value
-    re-used last.  The compressor can emit the sequence 256,2
-    at any time.
-
-Expanding - Methods 2-5
------------------------
-
-The Reducing algorithm is actually a combination of two
-distinct algorithms.  The first algorithm compresses repeated
-byte sequences, and the second algorithm takes the compressed
-stream from the first algorithm and applies a probabilistic
-compression method.
-
-The probabilistic compression stores an array of 'follower
-sets' S(j), for j=0 to 255, corresponding to each possible
-ASCII character.  Each set contains between 0 and 32
-characters, to be denoted as S(j)[0],...,S(j)[m], where m<32.
-The sets are stored at the beginning of the data area for a
-Reduced file, in reverse order, with S(255) first, and S(0)
-last.
-
-The sets are encoded as { N(j), S(j)[0],...,S(j)[N(j)-1] },
-where N(j) is the size of set S(j).  N(j) can be 0, in which
-case the follower set for S(j) is empty.  Each N(j) value is
-encoded in 6 bits, followed by N(j) eight bit character values
-corresponding to S(j)[0] to S(j)[N(j)-1] respectively.  If
-N(j) is 0, then no values for S(j) are stored, and the value
-for N(j-1) immediately follows.
-
-Immediately after the follower sets, is the compressed data
-stream.  The compressed data stream can be interpreted for the
-probabilistic decompression as follows:
-
-let Last-Character <- 0.
-loop until done
-    if the follower set S(Last-Character) is empty then
-        read 8 bits from the input stream, and copy this
-        value to the output stream.
-    otherwise if the follower set S(Last-Character) is non-empty then
-        read 1 bit from the input stream.
-        if this bit is not zero then
-            read 8 bits from the input stream, and copy this
-            value to the output stream.
-        otherwise if this bit is zero then
-            read B(N(Last-Character)) bits from the input
-            stream, and assign this value to I.
-            Copy the value of S(Last-Character)[I] to the
-            output stream.
-
-    assign the last value placed on the output stream to
-    Last-Character.
-end loop
-
-B(N(j)) is defined as the minimal number of bits required to
-encode the value N(j)-1.
-
-The decompressed stream from above can then be expanded to
-re-create the original file as follows:
-
-let State <- 0.
-
-loop until done
-    read 8 bits from the input stream into C.
-    case State of
-        0:  if C is not equal to DLE (144 decimal) then
-                copy C to the output stream.
-            otherwise if C is equal to DLE then
-                let State <- 1.
-
-        1:  if C is non-zero then
-                let V <- C.
-                let Len <- L(V)
-                let State <- F(Len).
-            otherwise if C is zero then
-                copy the value 144 (decimal) to the output stream.
-                let State <- 0
-
-        2:  let Len <- Len + C
-            let State <- 3.
-
-        3:  move backwards D(V,C) bytes in the output stream
-            (if this position is before the start of the output
-            stream, then assume that all the data before the
-            start of the output stream is filled with zeros).
-            copy Len+3 bytes from this position to the output stream.
-            let State <- 0.
-    end case
-end loop
-
-The functions F,L, and D are dependent on the 'compression
-factor', 1 through 4, and are defined as follows:
-
-For compression factor 1:
-    L(X) equals the lower 7 bits of X.
-    F(X) equals 2 if X equals 127 otherwise F(X) equals 3.
-    D(X,Y) equals the (upper 1 bit of X) * 256 + Y + 1.
-For compression factor 2:
-    L(X) equals the lower 6 bits of X.
-    F(X) equals 2 if X equals 63 otherwise F(X) equals 3.
-    D(X,Y) equals the (upper 2 bits of X) * 256 + Y + 1.
-For compression factor 3:
-    L(X) equals the lower 5 bits of X.
-    F(X) equals 2 if X equals 31 otherwise F(X) equals 3.
-    D(X,Y) equals the (upper 3 bits of X) * 256 + Y + 1.
-For compression factor 4:
-    L(X) equals the lower 4 bits of X.
-    F(X) equals 2 if X equals 15 otherwise F(X) equals 3.
-    D(X,Y) equals the (upper 4 bits of X) * 256 + Y + 1.
-
-Imploding - Method 6
---------------------
-
-The Imploding algorithm is actually a combination of two distinct
-algorithms.  The first algorithm compresses repeated byte
-sequences using a sliding dictionary.  The second algorithm is
-used to compress the encoding of the sliding dictionary output,
-using multiple Shannon-Fano trees.
-
-The Imploding algorithm can use a 4K or 8K sliding dictionary
-size. The dictionary size used can be determined by bit 1 in the
-general purpose flag word; a 0 bit indicates a 4K dictionary
-while a 1 bit indicates an 8K dictionary.
-
-The Shannon-Fano trees are stored at the start of the compressed
-file. The number of trees stored is defined by bit 2 in the
-general purpose flag word; a 0 bit indicates two trees stored, a
-1 bit indicates three trees are stored.  If 3 trees are stored,
-the first Shannon-Fano tree represents the encoding of the
-Literal characters, the second tree represents the encoding of
-the Length information, the third represents the encoding of the
-Distance information.  When 2 Shannon-Fano trees are stored, the
-Length tree is stored first, followed by the Distance tree.
-
-The Literal Shannon-Fano tree, if present is used to represent
-the entire ASCII character set, and contains 256 values.  This
-tree is used to compress any data not compressed by the sliding
-dictionary algorithm.  When this tree is present, the Minimum
-Match Length for the sliding dictionary is 3.  If this tree is
-not present, the Minimum Match Length is 2.
-
-The Length Shannon-Fano tree is used to compress the Length part
-of the (length,distance) pairs from the sliding dictionary
-output.  The Length tree contains 64 values, ranging from the
-Minimum Match Length, to 63 plus the Minimum Match Length.
-
-The Distance Shannon-Fano tree is used to compress the Distance
-part of the (length,distance) pairs from the sliding dictionary
-output. The Distance tree contains 64 values, ranging from 0 to
-63, representing the upper 6 bits of the distance value.  The
-distance values themselves will be between 0 and the sliding
-dictionary size, either 4K or 8K.
-
-The Shannon-Fano trees themselves are stored in a compressed
-format. The first byte of the tree data represents the number of
-bytes of data representing the (compressed) Shannon-Fano tree
-minus 1.  The remaining bytes represent the Shannon-Fano tree
-data encoded as:
-
-    High 4 bits: Number of values at this bit length + 1. (1 - 16)
-    Low  4 bits: Bit Length needed to represent value + 1. (1 - 16)
-
-The Shannon-Fano codes can be constructed from the bit lengths
-using the following algorithm:
-
-1)  Sort the Bit Lengths in ascending order, while retaining the
-    order of the original lengths stored in the file.
-
-2)  Generate the Shannon-Fano trees:
-
-    Code <- 0
-    CodeIncrement <- 0
-    LastBitLength <- 0
-    i <- number of Shannon-Fano codes - 1   (either 255 or 63)
-
-    loop while i >= 0
-        Code = Code + CodeIncrement
-        if BitLength(i) <> LastBitLength then
-            LastBitLength=BitLength(i)
-            CodeIncrement = 1 shifted left (16 - LastBitLength)
-        ShannonCode(i) = Code
-        i <- i - 1
-    end loop
-
-3)  Reverse the order of all the bits in the above ShannonCode()
-    vector, so that the most significant bit becomes the least
-    significant bit.  For example, the value 0x1234 (hex) would
-    become 0x2C48 (hex).
-
-4)  Restore the order of Shannon-Fano codes as originally stored
-    within the file.
-
-Example:
-
-    This example will show the encoding of a Shannon-Fano tree
-    of size 8.  Notice that the actual Shannon-Fano trees used
-    for Imploding are either 64 or 256 entries in size.
-
-Example:   0x02, 0x42, 0x01, 0x13
-
-    The first byte indicates 3 values in this table.  Decoding the
-    bytes:
-            0x42 = 5 codes of 3 bits long
-            0x01 = 1 code  of 2 bits long
-            0x13 = 2 codes of 4 bits long
-
-    This would generate the original bit length array of:
-    (3, 3, 3, 3, 3, 2, 4, 4)
-
-    There are 8 codes in this table for the values 0 thru 7.  Using 
-    the algorithm to obtain the Shannon-Fano codes produces:
-
-                                  Reversed     Order     Original
-Val  Sorted   Constructed Code      Value     Restored    Length
----  ------   -----------------   --------    --------    ------
-0:     2      1100000000000000        11       101          3
-1:     3      1010000000000000       101       001          3
-2:     3      1000000000000000       001       110          3
-3:     3      0110000000000000       110       010          3
-4:     3      0100000000000000       010       100          3
-5:     3      0010000000000000       100        11          2
-6:     4      0001000000000000      1000      1000          4
-7:     4      0000000000000000      0000      0000          4
-
-The values in the Val, Order Restored and Original Length columns
-now represent the Shannon-Fano encoding tree that can be used for
-decoding the Shannon-Fano encoded data.  How to parse the
-variable length Shannon-Fano values from the data stream is beyond
-the scope of this document.  (See the references listed at the end of
-this document for more information.)  However, traditional decoding
-schemes used for Huffman variable length decoding, such as the
-Greenlaw algorithm, can be successfully applied.
-
-The compressed data stream begins immediately after the
-compressed Shannon-Fano data.  The compressed data stream can be
-interpreted as follows:
-
-loop until done
-    read 1 bit from input stream.
-
-    if this bit is non-zero then       (encoded data is literal data)
-        if Literal Shannon-Fano tree is present
-            read and decode character using Literal Shannon-Fano tree.
-        otherwise
-            read 8 bits from input stream.
-        copy character to the output stream.
-    otherwise              (encoded data is sliding dictionary match)
-        if 8K dictionary size
-            read 7 bits for offset Distance (lower 7 bits of offset).
-        otherwise
-            read 6 bits for offset Distance (lower 6 bits of offset).
-
-        using the Distance Shannon-Fano tree, read and decode the
-          upper 6 bits of the Distance value.
-
-        using the Length Shannon-Fano tree, read and decode
-          the Length value.
-
-        Length <- Length + Minimum Match Length
-
-        if Length = 63 + Minimum Match Length
-            read 8 bits from the input stream,
-            add this value to Length.
-
-        move backwards Distance+1 bytes in the output stream, and
-        copy Length characters from this position to the output
-        stream.  (if this position is before the start of the output
-        stream, then assume that all the data before the start of
-        the output stream is filled with zeros).

-Tokenizing - Method 7
----------------------
-
-This method is not used by PKZIP.
-
-Deflating - Method 8
---------------------
-
-The Deflate algorithm is similar to the Implode algorithm using
-a sliding dictionary of up to 32K with secondary compression
-from Huffman/Shannon-Fano codes.
-
-The compressed data is stored in blocks with a header describing
-the block and the Huffman codes used in the data block.  The header
-format is as follows:
-
-   Bit 0: Last Block bit     This bit is set to 1 if this is the last
-                             compressed block in the data.
-   Bits 1-2: Block type
-      00 (0) - Block is stored - All stored data is byte aligned.
-               Skip bits until next byte, then next word = block 
-               length, followed by the ones compliment of the block
-               length word. Remaining data in block is the stored 
-               data.
-
-      01 (1) - Use fixed Huffman codes for literal and distance codes.
-               Lit Code    Bits             Dist Code   Bits
-               ---------   ----             ---------   ----
-                 0 - 143    8                 0 - 31      5
-               144 - 255    9
-               256 - 279    7
-               280 - 287    8
-
-               Literal codes 286-287 and distance codes 30-31 are 
-               never used but participate in the huffman construction.
-
-      10 (2) - Dynamic Huffman codes.  (See expanding Huffman codes)
-
-      11 (3) - Reserved - Flag a "Error in compressed data" if seen.
-
-Expanding Huffman Codes
------------------------
-If the data block is stored with dynamic Huffman codes, the Huffman
-codes are sent in the following compressed format:
-
-   5 Bits: # of Literal codes sent - 256 (256 - 286)
-           All other codes are never sent.
-   5 Bits: # of Dist codes - 1           (1 - 32)
-   4 Bits: # of Bit Length codes - 3     (3 - 19)
-
-The Huffman codes are sent as bit lengths and the codes are built as
-described in the implode algorithm.  The bit lengths themselves are
-compressed with Huffman codes.  There are 19 bit length codes:
-
-   0 - 15: Represent bit lengths of 0 - 15
-       16: Copy the previous bit length 3 - 6 times.
-           The next 2 bits indicate repeat length (0 = 3, ... ,3 = 6)
-              Example:  Codes 8, 16 (+2 bits 11), 16 (+2 bits 10) will
-                        expand to 12 bit lengths of 8 (1 + 6 + 5)
-       17: Repeat a bit length of 0 for 3 - 10 times. (3 bits of length)
-       18: Repeat a bit length of 0 for 11 - 138 times (7 bits of length)
-
-The lengths of the bit length codes are sent packed 3 bits per value
-(0 - 7) in the following order:
-
-   16, 17, 18, 0, 8, 7, 9, 6, 10, 5, 11, 4, 12, 3, 13, 2, 14, 1, 15
-
-The Huffman codes should be built as described in the Implode algorithm
-except codes are assigned starting at the shortest bit length, i.e. the
-shortest code should be all 0's rather than all 1's.  Also, codes with
-a bit length of zero do not participate in the tree construction.  The
-codes are then used to decode the bit lengths for the literal and 
-distance tables.
-
-The bit lengths for the literal tables are sent first with the number
-of entries sent described by the 5 bits sent earlier.  There are up
-to 286 literal characters; the first 256 represent the respective 8
-bit character, code 256 represents the End-Of-Block code, the remaining
-29 codes represent copy lengths of 3 thru 258.  There are up to 30
-distance codes representing distances from 1 thru 32k as described
-below.

-Enhanced Deflating - Method 9
------------------------------
-
-The Enhanced Deflating algorithm is similar to Deflate but
-uses a sliding dictionary of up to 64K. Deflate64(tm) is supported
-by the Deflate extractor. 
-
-BZIP2 - Method 12
------------------
-
-BZIP2 is an open-source data compression algorithm developed by 
-Julian Seward.  Information and source code for this algorithm
-can be found on the internet.
-
-LZMA - Method 14 (EFS)
-----------------------
-
-LZMA is a block-oriented, general purpose data compression algorithm  
-developed and maintained by Igor Pavlov.  It is a derivative of LZ77
-that utilizes Markov chains and a range coder.  Information and 
-source code for this algorithm can be found on the internet.  Consult 
-with the author of this algorithm for information on terms or 
-restrictions on use.
-
-Support for LZMA within the ZIP format is defined as follows:   
-
-The Compression method field within the ZIP Local and Central 
-Header records will be set to the value 14 to indicate data was
-compressed using LZMA. 
-
-The Version needed to extract field within the ZIP Local and 
-Central Header records will be set to 6.3 to indicate the 
-minimum ZIP format version supporting this feature.
-
-File data compressed using the LZMA algorithm must be placed 
-immediately following the Local Header for the file.  If a 
-standard ZIP encryption header is required, it will follow 
-the Local Header and will precede the LZMA compressed file 
-data segment.  The location of LZMA compressed data segment 
-within the ZIP format will be as shown:
-
-    [local header file 1]
-    [encryption header file 1]
-    [LZMA compressed data segment for file 1]
-    [data descriptor 1]
-    [local header file 2]
-
-The encryption header and data descriptor records may
-be conditionally present.  The LZMA Compressed Data Segment 
-will consist of an LZMA Properties Header followed by the 
-LZMA Compressed Data as shown:
-
-    [LZMA properties header for file 1]
-    [LZMA compressed data for file 1]
-
-The LZMA Compressed Data will be stored as provided by the 
-LZMA compression library.  Compressed size, uncompressed 
-size and other file characteristics about the file being 
-compressed must be stored in standard ZIP storage format.
-
-The LZMA Properties Header will store specific data required to 
-decompress the LZMA compressed Data.  This data is set by the 
-LZMA compression engine using the function WriteCoderProperties() 
-as documented within the LZMA SDK. 
- 
-Storage fields for the property information within the LZMA 
-Properties Header are as follows:
-
-     LZMA Version Information 2 bytes
-     LZMA Properties Size 2 bytes
-     LZMA Properties Data variable, defined by "LZMA Properties Size"
-
-LZMA Version Information - this field identifies which version of 
-     the LZMA SDK was used to compress a file.  The first byte will 
-     store the major version number of the LZMA SDK and the second 
-     byte will store the minor number.  
-
-LZMA Properties Size - this field defines the size of the remaining 
-     property data.  Typically this size should be determined by the 
-     version of the SDK.  This size field is included as a convenience
-     and to help avoid any ambiguity should it arise in the future due
-     to changes in this compression algorithm. 
-
-LZMA Property Data - this variable sized field records the required 
-     values for the decompressor as defined by the LZMA SDK.  The 
-     data stored in this field should be obtained using the 
-     WriteCoderProperties() in the version of the SDK defined by 
-     the "LZMA Version Information" field.  
-
-The layout of the "LZMA Properties Data" field is a function of the
-LZMA compression algorithm.  It is possible that this layout may be
-changed by the author over time.  The data layout in version 4.32 
-of the LZMA SDK defines a 5 byte array that uses 4 bytes to store 
-the dictionary size in little-endian order. This is preceded by a 
-single packed byte as the first element of the array that contains
-the following fields:
-
-     PosStateBits
-     LiteralPosStateBits
-     LiteralContextBits
-
-Refer to the LZMA documentation for a more detailed explanation of 
-these fields.  
-
-Data compressed with method 14, LZMA, may include an end-of-stream
-(EOS) marker ending the compressed data stream.  This marker is not
-required, but its use is highly recommended to facilitate processing
-and implementers should include the EOS marker whenever possible.
-When the EOS marker is used, general purpose bit 1 must be set.  If
-general purpose bit 1 is not set, the EOS marker is not present.
-
-WavPack - Method 97
--------------------
-
-Information describing the use of compression method 97 is 
-provided by WinZIP International, LLC.  This method relies on the
-open source WavPack audio compression utility developed by David Bryant.  
-Information on WavPack is available at www.wavpack.com.  Please consult 
-with the author of this algorithm for information on terms and 
-restrictions on use.
-
-WavPack data for a file begins immediately after the end of the
-local header data.  This data is the output from WavPack compression
-routines.  Within the ZIP file, the use of WavPack compression is
-indicated by setting the compression method field to a value of 97 
-in both the local header and the central directory header.  The Version 
-needed to extract and version made by fields use the same values as are 
-used for data compressed using the Deflate algorithm.
-
-An implementation note for storing digital sample data when using 
-WavPack compression within ZIP files is that all of the bytes of
-the sample data should be compressed.  This includes any unused
-bits up to the byte boundary.  An example is a 2 byte sample that
-uses only 12 bits for the sample data with 4 unused bits.  If only
-12 bits are passed as the sample size to the WavPack routines, the 4 
-unused bits will be set to 0 on extraction regardless of their original 
-state.  To avoid this, the full 16 bits of the sample data size
-should be provided. 
-
-PPMd - Method 98
-----------------
-
-PPMd is a data compression algorithm developed by Dmitry Shkarin
-which includes a carryless rangecoder developed by Dmitry Subbotin.
-This algorithm is based on predictive phrase matching on multiple
-order contexts.  Information and source code for this algorithm
-can be found on the internet. Consult with the author of this
-algorithm for information on terms or restrictions on use.
-
-Support for PPMd within the ZIP format currently is provided only 
-for version I, revision 1 of the algorithm.  Storage requirements
-for using this algorithm are as follows:
-
-Parameters needed to control the algorithm are stored in the two
-bytes immediately preceding the compressed data.  These bytes are
-used to store the following fields:
-
-Model order - sets the maximum model order, default is 8, possible
-              values are from 2 to 16 inclusive
-
-Sub-allocator size - sets the size of sub-allocator in MB, default is 50,
-            possible values are from 1MB to 256MB inclusive
-
-Model restoration method - sets the method used to restart context
-            model at memory insufficiency, values are:
-
-            0 - restarts model from scratch - default
-            1 - cut off model - decreases performance by as much as 2x
-            2 - freeze context tree - not recommended
-
-An example for packing these fields into the 2 byte storage field is
-illustrated below.  These values are stored in Intel low-byte/high-byte
-order.
-
-wPPMd = (Model order - 1) + 
-        ((Sub-allocator size - 1) << 4) + 
-        (Model restoration method << 12)

-VII. Traditional PKWARE Encryption
-----------------------------------
-
-The following information discusses the decryption steps
-required to support traditional PKWARE encryption.  This
-form of encryption is considered weak by today's standards
-and its use is recommended only for situations with
-low security needs or for compatibility with older .ZIP 
-applications.
-
-Decryption
-----------
-
-PKWARE is grateful to Mr. Roger Schlafly for his expert contribution 
-towards the development of PKWARE's traditional encryption.
-
-PKZIP encrypts the compressed data stream.  Encrypted files must
-be decrypted before they can be extracted.
-
-Each encrypted file has an extra 12 bytes stored at the start of
-the data area defining the encryption header for that file.  The
-encryption header is originally set to random values, and then
-itself encrypted, using three, 32-bit keys.  The key values are
-initialized using the supplied encryption password.  After each byte
-is encrypted, the keys are then updated using pseudo-random number
-generation techniques in combination with the same CRC-32 algorithm
-used in PKZIP and described elsewhere in this document.
-
-The following is the basic steps required to decrypt a file:
-
-1) Initialize the three 32-bit keys with the password.
-2) Read and decrypt the 12-byte encryption header, further
-   initializing the encryption keys.
-3) Read and decrypt the compressed data stream using the
-   encryption keys.
-
-Step 1 - Initializing the encryption keys
------------------------------------------
-
-Key(0) <- 305419896
-Key(1) <- 591751049
-Key(2) <- 878082192
-
-loop for i <- 0 to length(password)-1
-    update_keys(password(i))
-end loop
-
-Where update_keys() is defined as:
-
-update_keys(char):
-  Key(0) <- crc32(key(0),char)
-  Key(1) <- Key(1) + (Key(0) & 000000ffH)
-  Key(1) <- Key(1) * 134775813 + 1
-  Key(2) <- crc32(key(2),key(1) >> 24)
-end update_keys
-
-Where crc32(old_crc,char) is a routine that given a CRC value and a
-character, returns an updated CRC value after applying the CRC-32
-algorithm described elsewhere in this document.
-
-Step 2 - Decrypting the encryption header
------------------------------------------
-
-The purpose of this step is to further initialize the encryption
-keys, based on random data, to render a plaintext attack on the
-data ineffective.
-
-Read the 12-byte encryption header into Buffer, in locations
-Buffer(0) thru Buffer(11).
-
-loop for i <- 0 to 11
-    C <- buffer(i) ^ decrypt_byte()
-    update_keys(C)
-    buffer(i) <- C
-end loop
-
-Where decrypt_byte() is defined as:
-
-unsigned char decrypt_byte()
-    local unsigned short temp
-    temp <- Key(2) | 2
-    decrypt_byte <- (temp * (temp ^ 1)) >> 8
-end decrypt_byte
-
-After the header is decrypted,  the last 1 or 2 bytes in Buffer
-should be the high-order word/byte of the CRC for the file being
-decrypted, stored in Intel low-byte/high-byte order.  Versions of
-PKZIP prior to 2.0 used a 2 byte CRC check; a 1 byte CRC check is
-used on versions after 2.0.  This can be used to test if the password
-supplied is correct or not.
-
-Step 3 - Decrypting the compressed data stream
-----------------------------------------------
-
-The compressed data stream can be decrypted as follows:
-
-loop until done
-    read a character into C
-    Temp <- C ^ decrypt_byte()
-    update_keys(temp)
-    output Temp
-end loop
-
-
-VIII. Strong Encryption Specification
--------------------------------------
-
-The Strong Encryption technology defined in this specification is 
-covered under a pending patent application. The use or implementation
-in a product of certain technological aspects set forth in the current
-APPNOTE, including those with regard to strong encryption, patching, 
-or extended tape operations requires a license from PKWARE. Portions
-of this Strong Encryption technology are available for use at no charge.
-Contact PKWARE for licensing terms and conditions. Refer to section II
-of this APPNOTE (Contacting PKWARE) for information on how to 
-contact PKWARE. 
-
-Version 5.x of this specification introduced support for strong 
-encryption algorithms.  These algorithms can be used with either 
-a password or an X.509v3 digital certificate to encrypt each file. 
-This format specification supports either password or certificate 
-based encryption to meet the security needs of today, to enable 
-interoperability between users within both PKI and non-PKI 
-environments, and to ensure interoperability between different 
-computing platforms that are running a ZIP program.  
-
-Password based encryption is the most common form of encryption 
-people are familiar with.  However, inherent weaknesses with 
-passwords (e.g. susceptibility to dictionary/brute force attack) 
-as well as password management and support issues make certificate 
-based encryption a more secure and scalable option.  Industry 
-efforts and support are defining and moving towards more advanced 
-security solutions built around X.509v3 digital certificates and 
-Public Key Infrastructures(PKI) because of the greater scalability, 
-administrative options, and more robust security over traditional 
-password based encryption. 
-
-Most standard encryption algorithms are supported with this
-specification. Reference implementations for many of these 
-algorithms are available from either commercial or open source 
-distributors.  Readily available cryptographic toolkits make
-implementation of the encryption features straight-forward.  
-This document is not intended to provide a treatise on data 
-encryption principles or theory.  Its purpose is to document the 
-data structures required for implementing interoperable data 
-encryption within the .ZIP format.  It is strongly recommended that 
-you have a good understanding of data encryption before reading 
-further.
-
-The algorithms introduced in Version 5.0 of this specification 
-include:
-
-    RC2 40 bit, 64 bit, and 128 bit
-    RC4 40 bit, 64 bit, and 128 bit
-    DES
-    3DES 112 bit and 168 bit
-  
-Version 5.1 adds support for the following:
-
-    AES 128 bit, 192 bit, and 256 bit
-
-
-Version 6.1 introduces encryption data changes to support 
-interoperability with Smartcard and USB Token certificate storage 
-methods which do not support the OAEP strengthening standard.
-
-Version 6.2 introduces support for encrypting metadata by compressing 
-and encrypting the central directory data structure to reduce information 
-leakage.   Information leakage can occur in legacy ZIP applications 
-through exposure of information about a file even though that file is 
-stored encrypted.  The information exposed consists of file 
-characteristics stored within the records and fields defined by this 
-specification.  This includes data such as a files name, its original 
-size, timestamp and CRC32 value. 
-
-Version 6.3 introduces support for encrypting data using the Blowfish
-and Twofish algorithms.  These are symmetric block ciphers developed 
-by Bruce Schneier.  Blowfish supports using a variable length key from 
-32 to 448 bits.  Block size is 64 bits.  Implementations should use 16
-rounds and the only mode supported within ZIP files is CBC. Twofish 
-supports key sizes 128, 192 and 256 bits.  Block size is 128 bits.  
-Implementations should use 16 rounds and the only mode supported within
-ZIP files is CBC.  Information and source code for both Blowfish and 
-Twofish algorithms can be found on the internet.  Consult with the author
-of these algorithms for information on terms or restrictions on use.
-
-Central Directory Encryption provides greater protection against 
-information leakage by encrypting the Central Directory structure and 
-by masking key values that are replicated in the unencrypted Local 
-Header.   ZIP compatible programs that cannot interpret an encrypted 
-Central Directory structure cannot rely on the data in the corresponding 
-Local Header for decompression information.  
-
-Extra Field records that may contain information about a file that should 
-not be exposed should not be stored in the Local Header and should only 
-be written to the Central Directory where they can be encrypted.  This 
-design currently does not support streaming.  Information in the End of 
-Central Directory record, the Zip64 End of Central Directory Locator, 
-and the Zip64 End of Central Directory records are not encrypted.  Access 
-to view data on files within a ZIP file with an encrypted Central Directory
-requires the appropriate password or private key for decryption prior to 
-viewing any files, or any information about the files, in the archive.  
-
-Older ZIP compatible programs not familiar with the Central Directory 
-Encryption feature will no longer be able to recognize the Central 
-Directory and may assume the ZIP file is corrupt.  Programs that 
-attempt streaming access using Local Headers will see invalid 
-information for each file.  Central Directory Encryption need not be 
-used for every ZIP file.  Its use is recommended for greater security.  
-ZIP files not using Central Directory Encryption should operate as 
-in the past. 
-
-This strong encryption feature specification is intended to provide for 
-scalable, cross-platform encryption needs ranging from simple password
-encryption to authenticated public/private key encryption.  
-
-Encryption provides data confidentiality and privacy.  It is 
-recommended that you combine X.509 digital signing with encryption 
-to add authentication and non-repudiation.
-
-
-Single Password Symmetric Encryption Method:
--------------------------------------------
-
-The Single Password Symmetric Encryption Method using strong 
-encryption algorithms operates similarly to the traditional 
-PKWARE encryption defined in this format.  Additional data 
-structures are added to support the processing needs of the 
-strong algorithms.
-
-The Strong Encryption data structures are:
-
-1. General Purpose Bits - Bits 0 and 6 of the General Purpose bit 
-flag in both local and central header records.  Both bits set 
-indicates strong encryption.  Bit 13, when set indicates the Central
-Directory is encrypted and that selected fields in the Local Header
-are masked to hide their actual value.
-
-
-2. Extra Field 0x0017 in central header only.
-
-     Fields to consider in this record are:
-
-     Format - the data format identifier for this record.  The only
-     value allowed at this time is the integer value 2.
-
-     AlgId - integer identifier of the encryption algorithm from the
-     following range
-
-         0x6601 - DES
-         0x6602 - RC2 (version needed to extract < 5.2)
-         0x6603 - 3DES 168
-         0x6609 - 3DES 112
-         0x660E - AES 128 
-         0x660F - AES 192 
-         0x6610 - AES 256 
-         0x6702 - RC2 (version needed to extract >= 5.2)
-         0x6720 - Blowfish
-         0x6721 - Twofish
-         0x6801 - RC4
-         0xFFFF - Unknown algorithm
-
-     Bitlen - Explicit bit length of key
-
-         32 - 448 bits
-   
-     Flags - Processing flags needed for decryption
-
-         0x0001 - Password is required to decrypt
-         0x0002 - Certificates only
-         0x0003 - Password or certificate required to decrypt
-
-         Values > 0x0003 reserved for certificate processing
-
-
-3. Decryption header record preceding compressed file data.
-
-         -Decryption Header:
-
-          Value     Size     Description
-          -----     ----     -----------
-          IVSize    2 bytes  Size of initialization vector (IV)
-          IVData    IVSize   Initialization vector for this file
-          Size      4 bytes  Size of remaining decryption header data
-          Format    2 bytes  Format definition for this record
-          AlgID     2 bytes  Encryption algorithm identifier
-          Bitlen    2 bytes  Bit length of encryption key
-          Flags     2 bytes  Processing flags
-          ErdSize   2 bytes  Size of Encrypted Random Data
-          ErdData   ErdSize  Encrypted Random Data
-          Reserved1 4 bytes  Reserved certificate processing data
-          Reserved2 (var)    Reserved for certificate processing data
-          VSize     2 bytes  Size of password validation data
-          VData     VSize-4  Password validation data
-          VCRC32    4 bytes  Standard ZIP CRC32 of password validation data
-
-     IVData - The size of the IV should match the algorithm block size.
-              The IVData can be completely random data.  If the size of
-              the randomly generated data does not match the block size
-              it should be complemented with zero's or truncated as
-              necessary.  If IVSize is 0,then IV = CRC32 + Uncompressed
-              File Size (as a 64 bit little-endian, unsigned integer value).
-
-     Format - the data format identifier for this record.  The only
-     value allowed at this time is the integer value 3.
-
-     AlgId - integer identifier of the encryption algorithm from the
-     following range
-
-         0x6601 - DES
-         0x6602 - RC2 (version needed to extract < 5.2)
-         0x6603 - 3DES 168
-         0x6609 - 3DES 112
-         0x660E - AES 128 
-         0x660F - AES 192 
-         0x6610 - AES 256 
-         0x6702 - RC2 (version needed to extract >= 5.2)
-         0x6720 - Blowfish
-         0x6721 - Twofish
-         0x6801 - RC4
-         0xFFFF - Unknown algorithm
-
-     Bitlen - Explicit bit length of key
-
-         32 - 448 bits
-   
-     Flags - Processing flags needed for decryption
-
-         0x0001 - Password is required to decrypt
-         0x0002 - Certificates only
-         0x0003 - Password or certificate required to decrypt
-
-         Values > 0x0003 reserved for certificate processing
-
-     ErdData - Encrypted random data is used to store random data that
-               is used to generate a file session key for encrypting 
-               each file.  SHA1 is used to calculate hash data used to 
-               derive keys.  File session keys are derived from a master 
-               session key generated from the user-supplied password.
-               If the Flags field in the decryption header contains 
-               the value 0x4000, then the ErdData field must be 
-               decrypted using 3DES. If the value 0x4000 is not set,
-               then the ErdData field must be decrypted using AlgId.
-
-
-     Reserved1 - Reserved for certificate processing, if value is
-               zero, then Reserved2 data is absent.  See the explanation
-               under the Certificate Processing Method for details on
-               this data structure.
-
-     Reserved2 - If present, the size of the Reserved2 data structure 
-               is located by skipping the first 4 bytes of this field 
-               and using the next 2 bytes as the remaining size.  See
-               the explanation under the Certificate Processing Method
-               for details on this data structure.
-
-     VSize - This size value will always include the 4 bytes of the
-             VCRC32 data and will be greater than 4 bytes.
-
-     VData - Random data for password validation.  This data is VSize
-             in length and VSize must be a multiple of the encryption
-             block size.  VCRC32 is a checksum value of VData.  
-             VData and VCRC32 are stored encrypted and start the
-             stream of encrypted data for a file.
-
-
-4. Useful Tips
-
-Strong Encryption is always applied to a file after compression. The
-block oriented algorithms all operate in Cypher Block Chaining (CBC) 
-mode.  The block size used for AES encryption is 16.  All other block
-algorithms use a block size of 8.  Two ID's are defined for RC2 to 
-account for a discrepancy found in the implementation of the RC2
-algorithm in the cryptographic library on Windows XP SP1 and all 
-earlier versions of Windows.  It is recommended that zero length files
-not be encrypted, however programs should be prepared to extract them
-if they are found within a ZIP file.
-
-A pseudo-code representation of the encryption process is as follows:
-
-Password = GetUserPassword()
-MasterSessionKey = DeriveKey(SHA1(Password)) 
-RD = CryptographicStrengthRandomData() 
-For Each File
-   IV = CryptographicStrengthRandomData() 
-   VData = CryptographicStrengthRandomData()
-   VCRC32 = CRC32(VData)
-   FileSessionKey = DeriveKey(SHA1(IV + RD) 
-   ErdData = Encrypt(RD,MasterSessionKey,IV) 
-   Encrypt(VData + VCRC32 + FileData, FileSessionKey,IV)
-Done
-
-The function names and parameter requirements will depend on
-the choice of the cryptographic toolkit selected.  Almost any
-toolkit supporting the reference implementations for each
-algorithm can be used.  The RSA BSAFE(r), OpenSSL, and Microsoft
-CryptoAPI libraries are all known to work well.  
-
-
-Single Password - Central Directory Encryption:
------------------------------------------------
-
-Central Directory Encryption is achieved within the .ZIP format by 
-encrypting the Central Directory structure.  This encapsulates the metadata 
-most often used for processing .ZIP files.  Additional metadata is stored for 
-redundancy in the Local Header for each file.  The process of concealing 
-metadata by encrypting the Central Directory does not protect the data within 
-the Local Header.  To avoid information leakage from the exposed metadata 
-in the Local Header, the fields containing information about a file are masked.  
-
-Local Header:
-
-Masking replaces the true content of the fields for a file in the Local 
-Header with false information.  When masked, the Local Header is not 
-suitable for streaming access and the options for data recovery of damaged
-archives is reduced.  Extra Data fields that may contain confidential
-data should not be stored within the Local Header.  The value set into
-the Version needed to extract field should be the correct value needed to
-extract the file without regard to Central Directory Encryption. The fields 
-within the Local Header targeted for masking when the Central Directory is 
-encrypted are:
-
-        Field Name                     Mask Value
-        ------------------             ---------------------------
-        compression method              0
-        last mod file time              0
-        last mod file date              0
-        crc-32                          0
-        compressed size                 0
-        uncompressed size               0
-        file name (variable size)       Base 16 value from the
-                                        range 1 - 0xFFFFFFFFFFFFFFFF
-                                        represented as a string whose
-                                        size will be set into the
-                                        file name length field
-
-The Base 16 value assigned as a masked file name is simply a sequentially
-incremented value for each file starting with 1 for the first file.  
-Modifications to a ZIP file may cause different values to be stored for 
-each file.  For compatibility, the file name field in the Local Header 
-should never be left blank.  As of Version 6.2 of this specification, 
-the Compression Method and Compressed Size fields are not yet masked.
-Fields having a value of 0xFFFF or 0xFFFFFFFF for the ZIP64 format
-should not be masked.  
-
-Encrypting the Central Directory:
-
-Encryption of the Central Directory does not include encryption of the 
-Central Directory Signature data, the Zip64 End of Central Directory
-record, the Zip64 End of Central Directory Locator, or the End
-of Central Directory record.  The ZIP file comment data is never
-encrypted.
-
-Before encrypting the Central Directory, it may optionally be compressed.
-Compression is not required, but for storage efficiency it is assumed
-this structure will be compressed before encrypting.  Similarly, this 
-specification supports compressing the Central Directory without
-requiring that it also be encrypted.  Early implementations of this
-feature will assume the encryption method applied to files matches the 
-encryption applied to the Central Directory.
-
-Encryption of the Central Directory is done in a manner similar to
-that of file encryption.  The encrypted data is preceded by a 
-decryption header.  The decryption header is known as the Archive
-Decryption Header.  The fields of this record are identical to
-the decryption header preceding each encrypted file.  The location
-of the Archive Decryption Header is determined by the value in the
-Start of the Central Directory field in the Zip64 End of Central
-Directory record.  When the Central Directory is encrypted, the
-Zip64 End of Central Directory record will always be present.
-
-The layout of the Zip64 End of Central Directory record for all
-versions starting with 6.2 of this specification will follow the
-Version 2 format.  The Version 2 format is as follows:
-
-The leading fixed size fields within the Version 1 format for this
-record remain unchanged.  The record signature for both Version 1 
-and Version 2 will be 0x06064b50.  Immediately following the last
-byte of the field known as the Offset of Start of Central 
-Directory With Respect to the Starting Disk Number will begin the 
-new fields defining Version 2 of this record.  
-
-New fields for Version 2:
-
-Note: all fields stored in Intel low-byte/high-byte order.
-
-          Value                 Size       Description
-          -----                 ----       -----------
-          Compression Method    2 bytes    Method used to compress the
-                                           Central Directory
-          Compressed Size       8 bytes    Size of the compressed data
-          Original   Size       8 bytes    Original uncompressed size
-          AlgId                 2 bytes    Encryption algorithm ID
-          BitLen                2 bytes    Encryption key length
-          Flags                 2 bytes    Encryption flags
-          HashID                2 bytes    Hash algorithm identifier
-          Hash Length           2 bytes    Length of hash data
-          Hash Data             (variable) Hash data
-
-The Compression Method accepts the same range of values as the 
-corresponding field in the Central Header.
-
-The Compressed Size and Original Size values will not include the
-data of the Central Directory Signature which is compressed or
-encrypted.
-
-The AlgId, BitLen, and Flags fields accept the same range of values
-the corresponding fields within the 0x0017 record. 
-
-Hash ID identifies the algorithm used to hash the Central Directory 
-data.  This data does not have to be hashed, in which case the
-values for both the HashID and Hash Length will be 0.  Possible 
-values for HashID are:
-
-      Value         Algorithm
-     ------         ---------
-     0x0000          none
-     0x0001          CRC32
-     0x8003          MD5
-     0x8004          SHA1
-     0x8007          RIPEMD160
-     0x800C          SHA256
-     0x800D          SHA384
-     0x800E          SHA512
-
-When the Central Directory data is signed, the same hash algorithm
-used to hash the Central Directory for signing should be used.
-This is recommended for processing efficiency, however, it is 
-permissible for any of the above algorithms to be used independent 
-of the signing process.
-
-The Hash Data will contain the hash data for the Central Directory.
-The length of this data will vary depending on the algorithm used.
-
-The Version Needed to Extract should be set to 62.
-
-The value for the Total Number of Entries on the Current Disk will
-be 0.  These records will no longer support random access when
-encrypting the Central Directory.
-
-When the Central Directory is compressed and/or encrypted, the
-End of Central Directory record will store the value 0xFFFFFFFF
-as the value for the Total Number of Entries in the Central
-Directory.  The value stored in the Total Number of Entries in
-the Central Directory on this Disk field will be 0.  The actual
-values will be stored in the equivalent fields of the Zip64
-End of Central Directory record.
-
-Decrypting and decompressing the Central Directory is accomplished
-in the same manner as decrypting and decompressing a file.
-
-Certificate Processing Method:
------------------------------
-
-The Certificate Processing Method of for ZIP file encryption 
-defines the following additional data fields:
-
-1. Certificate Flag Values
-
-Additional processing flags that can be present in the Flags field of both 
-the 0x0017 field of the central directory Extra Field and the Decryption 
-header record preceding compressed file data are:
-
-         0x0007 - reserved for future use
-         0x000F - reserved for future use
-         0x0100 - Indicates non-OAEP key wrapping was used.  If this
-                  this field is set, the version needed to extract must
-                  be at least 61.  This means OAEP key wrapping is not
-                  used when generating a Master Session Key using

-
-     HSize     This defines the size of a hashed public key
-               defined in REHData.
-
-     REList    This is a variable length of list of recipient data.  
-               Each element in this list consists of a Recipient
-               Element data structure as follows:
-
-
-    Recipient Element (REList) Data Structure:
-
-          Value     Size     Description
-          -----     ----     -----------
-          RESize    2 bytes  Size of REHData + REKData
-          REHData   HSize    Hash of recipients public key
-          REKData   (var)    Simple key blob
-
-
-     RESize    This defines the size of an individual REList 
-               element.  This value is the combined size of the
-               REHData field + REKData field.  REHData is defined by
-               HSize.  REKData is variable and can be calculated
-               for each REList element using RESize and HSize.
-
-     REHData   Hashed public key for this recipient.
-
-     REKData   Simple Key Blob.  The format of this data structure
-               is identical to that defined in the Microsoft
-               CryptoAPI and generated using the CryptExportKey()
-               function.  The version of the Simple Key Blob
-               supported at this time is 0x02 as defined by
-               Microsoft.
-
-Certificate Processing - Central Directory Encryption:
-------------------------------------------------------
-
-Central Directory Encryption using Digital Certificates will 
-operate in a manner similar to that of Single Password Central
-Directory Encryption.  This record will only be present when there 
-is data to place into it.  Currently, data is placed into this
-record when digital certificates are used for either encrypting 
-or signing the files within a ZIP file.  When only password 
-encryption is used with no certificate encryption or digital 
-signing, this record is not currently needed. When present, this 
-record will appear before the start of the actual Central Directory 
-data structure and will be located immediately after the Archive 
-Decryption Header if the Central Directory is encrypted.
-
-The Archive Extra Data record will be used to store the following
-information.  Additional data may be added in future versions.
-
-Extra Data Fields:
-
-0x0014 - PKCS#7 Store for X.509 Certificates
-0x0016 - X.509 Certificate ID and Signature for central directory
-0x0019 - PKCS#7 Encryption Recipient Certificate List
-
-The 0x0014 and 0x0016 Extra Data records that otherwise would be 
-located in the first record of the Central Directory for digital 
-certificate processing. When encrypting or compressing the Central 
-Directory, the 0x0014 and 0x0016 records must be located in the 
-Archive Extra Data record and they should not remain in the first 
-Central Directory record.  The Archive Extra Data record will also 
-be used to store the 0x0019 data. 
-
-When present, the size of the Archive Extra Data record will be
-included in the size of the Central Directory.  The data of the
-Archive Extra Data record will also be compressed and encrypted
-along with the Central Directory data structure.
-
-Certificate Processing Differences:
-
-The Certificate Processing Method of encryption differs from the
-Single Password Symmetric Encryption Method as follows.  Instead
-of using a user-defined password to generate a master session key,
-cryptographically random data is used.  The key material is then
-wrapped using standard key-wrapping techniques.  This key material
-is wrapped using the public key of each recipient that will need
-to decrypt the file using their corresponding private key.
-
-This specification currently assumes digital certificates will follow
-the X.509 V3 format for 1024 bit and higher RSA format digital
-certificates.  Implementation of this Certificate Processing Method
-requires supporting logic for key access and management.  This logic
-is outside the scope of this specification.
-
-OAEP Processing with Certificate-based Encryption:
-
-OAEP stands for Optimal Asymmetric Encryption Padding.  It is a
-strengthening technique used for small encoded items such as decryption
-keys.  This is commonly applied in cryptographic key-wrapping techniques
-and is supported by PKCS #1.  Versions 5.0 and 6.0 of this specification 
-were designed to support OAEP key-wrapping for certificate-based 
-decryption keys for additional security.  
-
-Support for private keys stored on Smartcards or Tokens introduced
-a conflict with this OAEP logic.  Most card and token products do 
-not support the additional strengthening applied to OAEP key-wrapped 
-data.  In order to resolve this conflict, versions 6.1 and above of this 
-specification will no longer support OAEP when encrypting using 
-digital certificates. 
-
-Versions of PKZIP available during initial development of the 
-certificate processing method set a value of 61 into the 
-version needed to extract field for a file.  This indicates that 
-non-OAEP key wrapping is used.  This affects certificate encryption 
-only, and password encryption functions should not be affected by 
-this value.  This means values of 61 may be found on files encrypted
-with certificates only, or on files encrypted with both password
-encryption and certificate encryption.  Files encrypted with both
-methods can safely be decrypted using the password methods documented.
-
-IX. Change Process
-------------------
-
-In order for the .ZIP file format to remain a viable definition, this
-specification should be considered as open for periodic review and
-revision.  Although this format was originally designed with a 
-certain level of extensibility, not all changes in technology
-(present or future) were or will be necessarily considered in its
-design.  If your application requires new definitions to the
-extensible sections in this format, or if you would like to 
-submit new data structures, please forward your request to
-zipformat@pkware.com.  All submissions will be reviewed by the
-ZIP File Specification Committee for possible inclusion into
-future versions of this specification.  Periodic revisions
-to this specification will be published to ensure interoperability. 
-We encourage comments and feedback that may help improve clarity 
-or content.
-
-X. Incorporating PKWARE Proprietary Technology into Your Product
-----------------------------------------------------------------
-
-PKWARE is committed to the interoperability and advancement of the
-.ZIP format.  PKWARE offers a free license for certain technological
-aspects described above under certain restrictions and conditions.
-However, the use or implementation in a product of certain technological
-aspects set forth in the current APPNOTE, including those with regard to
-strong encryption, patching, or extended tape operations requires a 
-license from PKWARE.  Please contact PKWARE with regard to acquiring
-a license.

-APPENDIX D - Language Encoding (EFS)
-------------------------------------
-
-The ZIP format has historically supported only the original IBM PC character 
-encoding set, commonly referred to as IBM Code Page 437.  This limits storing 
-file name characters to only those within the original MS-DOS range of values 
-and does not properly support file names in other character encodings, or 
-languages. To address this limitation, this specification will support the 
-following change. 
-
-If general purpose bit 11 is unset, the file name and comment should conform 
-to the original ZIP character encoding.  If general purpose bit 11 is set, the 
-filename and comment must support The Unicode Standard, Version 4.1.0 or 
-greater using the character encoding form defined by the UTF-8 storage 
-specification.  The Unicode Standard is published by the The Unicode
-Consortium (www.unicode.org).  UTF-8 encoded data stored within ZIP files 
-is expected to not include a byte order mark (BOM). 
-
-Applications may choose to supplement this file name storage through the use 
-of the 0x0008 Extra Field.  Storage for this optional field is currently 
-undefined, however it will be used to allow storing extended information 
-on source or target encoding that may further assist applications with file 
-name, or file content encoding tasks.  Please contact PKWARE with any
-requirements on how this field should be used.
-
-The 0x0008 Extra Field storage may be used with either setting for general 
-purpose bit 11.  Examples of the intended usage for this field is to store 
-whether "modified-UTF-8" (JAVA) is used, or UTF-8-MAC.  Similarly, other 
-commonly used character encoding (code page) designations can be indicated 
-through this field.  Formalized values for use of the 0x0008 record remain 
-undefined at this time.  The definition for the layout of the 0x0008 field
-will be published when available.  Use of the 0x0008 Extra Field provides
-for storing data within a ZIP file in an encoding other than IBM Code
-Page 437 or UTF-8.
-
-General purpose bit 11 will not imply any encoding of file content or
-password.  Values defining character encoding for file content or 
-password must be stored within the 0x0008 Extended Language Encoding 
-Extra Field.
-
-Ed Gordon of the Info-ZIP group has defined a pair of "extra field" records 
-that can be used to store UTF-8 file name and file comment fields.  These
-records can be used for cases when the general purpose bit 11 method
-for storing UTF-8 data in the standard file name and comment fields is
-not desirable.  A common case for this alternate method is if backward
-compatibility with older programs is required.
-
-Definitions for the record structure of these fields are included above 
-in the section on 3rd party mappings for "extra field" records.  These
-records are identified by Header ID's 0x6375 (Info-ZIP Unicode Comment 
-Extra Field) and 0x7075 (Info-ZIP Unicode Path Extra Field).
-
-The choice of which storage method to use when writing a ZIP file is left
-to the implementation.  Developers should expect that a ZIP file may 
-contain either method and should provide support for reading data in 
-either format. Use of general purpose bit 11 reduces storage requirements 
-for file name data by not requiring additional "extra field" data for
-each file, but can result in older ZIP programs not being able to extract 
-files.  Use of the 0x6375 and 0x7075 records will result in a ZIP file 
-that should always be readable by older ZIP programs, but requires more 
-storage per file to write file name and/or file comment fields.

-JSZip uses objects that may not exist on every platform, in which case it uses
-a shim.
-Accessing or replacing these objects can sometimes be useful. JSZip.external
-contains the following properties :
-
-* `Promise` : the [Promise](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise) implementation used.
-
-The global object is preferred when available.
-
-__Example__

-JSZip.external.Promise = Bluebird;
-

-## Arguments
-
-name                | type    | description
---------------------|---------|------------
-name                | string  | the name of the file. You can specify folders in the name : the folder separator is a forward slash ("/").
-data                | String/ArrayBuffer/Uint8Array/Buffer/Blob/Promise/Nodejs stream | the content of the file.
-options             | object  | the options.
-
-Content of `options` :
-
-name        | type    | default | description
-------------|---------|---------|------------
-base64      | boolean | `false` | set to `true` if the data is base64 encoded. For example image data from a `<canvas>` element. Plain text and HTML do not need this option. [More](#base64-option).
-binary      | boolean | `false` | set to `true` if the data should be treated as raw content, `false` if this is a text. If base64 is used, this defaults to `true`, if the data is not a string, this will be set to `true`. [More](#binary-option).
-date        | date    | the current date | the last modification date. [More](#date-option).
-compression | string  | null    | If set, specifies compression method to use for this specific file. If not, the default file compression will be used, see [generateAsync(options)]({{site.baseurl}}/documentation/api_jszip/generate_async.html). [More](#compression-and-compressionoptions-options).
-compressionOptions | object | `null` | the options to use when compressing the file, see [generateAsync(options)]({{site.baseurl}}/documentation/api_jszip/generate_async.html). [More](#compression-and-compressionoptions-options).
-comment     | string  | null    | The comment for this file. [More](#comment-option).
-optimizedBinaryString | boolean | `false` | Set to true if (and only if) the input is a "binary string" and has already been prepared with a 0xFF mask.
-createFolders | boolean | `true` | Set to true if folders in the file path should be automatically created, otherwise there will only be virtual folders that represent the path to the file. [More](#createfolders-option).
-unixPermissions | 16 bits number | null    | The UNIX permissions of the file, if any. [More](#unixpermissions-and-dospermissions-options).
-dosPermissions  | 6 bits number  | null    | The DOS permissions of the file, if any. [More](#unixpermissions-and-dospermissions-options).
-dir             | boolean        | false   | Set to true if this is a directory and content should be ignored. [More](#dir-option).
-
-### data input
-
-You shouldn't update the data given to this method: it is kept as it so any
-update will impact the stored data.
-
-#### About Promise <small>since v3.0.0</small>
-
-You can use a Promise of content directly to simplify async content handling.
-Let's use HTTP calls as examples:
-
-```js
-/** with promises **/
-
-// instead of
-$.get("url/to.file.txt") // jQuery v3 returns promises
-.then(function (content) {
-    zip.file("file.txt", content);
-})
-
-// you can do
-var promise = $.get("url/to.file.txt");
-zip.file("file.txt", promise);
-```
-
-```js
-/** with callbacks **/
-
-// instead of
-request('url/to.file.txt', function (error, response, body) {
-    zip.file("file.txt", body);
-});
-
-// you can do
-var promise = new Promise(function (resolve, reject) {
-    request('url/to.file.txt', function (error, response, body) {
-        if (error) {
-            reject(error);
-        } else {
-          resolve(body);
-        }
-    });
-});
-zip.file("file.txt", promise);
-```
-
-#### About Blob <small>since v3.0.0</small>
-
-You can use directly [Blob](https://developer.mozilla.org/en-US/docs/Web/API/Blob)
-as input, no need to use a `FileReader`.
-[File](https://developer.mozilla.org/en-US/docs/Web/API/File) objects are Blobs
-so you can use them directly:
-
-```js
-// in a change callback of a <input type="file">
-var files = evt.target.files;
-for (var i = 0; i < files.length; i++) {
-    var f = files[i];
-    zip.file(f.name, f);
-}
-```
-
-#### About nodejs stream <small>since v3.0.0</small>
-
-A stream can't be restarted: if it is used once, it can't be used again (
-by [generateAsync()]({{site.baseurl}}/documentation/api_jszip/generate_async.html)
-or by [ZipObject methods]({{site.baseurl}}/documentation/api_zipobject.html)).
-In that case, the promise/stream (depending on the method called) will get
-an error.
-
-
-### `base64` option
-
-```js
-var zip = new JSZip();
-zip.file("hello.txt", "aGVsbG8gd29ybGQK", {base64: true});
-```
-
-### `binary` option
-
-```js
-var zip = new JSZip();
-
-// here, we have a correct (unicode) string
-zip.file("hello.txt", "unicode ♥", {binary: false});
-
-// here, we have a binary string: it can contain binary content, one byte
-// per character.
-zip.file("hello.txt", "unicode \xE2\x99\xA5", {binary: true});
-```
-
-If you use a library that returns a binary string for example, you should use
-this option. Otherwise, you will get a corrupted result: JSZip will try to
-encode this string with UTF-8 when the content doesn't need to.
-
-### `date` option
-
-```js
-zip.file("Xmas.txt", "Ho ho ho !", {
-    date: new Date("December 25, 2007 00:00:01")
-});
-```
-
-### `compression` and `compressionOptions` options
-
-See also the same options on [`JSZip#generateAsync()`]({{site.baseurl}}/documentation/api_jszip/generate_async.html#compression-and-compressionoptions-options).
-
-These options will be used when generating a zip file. They let you override
-entry per entry the compression / compression options to use.
-
-```js
-zip.file("a.png", contentOfA, {
-    compression: "STORE" // force a compression for this file
-});
-zip.file("b.txt", contentOfA, {
-    compression: "DEFLATE",
-    compressionOptions: {
-        level: 9 // force a compression and a compression level for this file
-    }
-});
-
-// don't force anything, use the generateAsync options
-zip.file("c.txt", contentOfB);
-
-// here:
-// - a.png will not be compressed (STORE)
-// - b.txt will be compressed at maximum level
-// - c.txt will be compressed with the default compression level
-zip.generateAsync({
-    type: "blob",
-    compression: "DEFLATE"
-});
-```
-
-### `comment` option
-
-```js
-zip.file("a.txt", "content", {
-    comment: "comment of a.txt"
-});
-```
-
-### `createFolders` option
-
-```js
-zip.file("a/b/c/d.txt", "content", {
-    createFolders: true // default value
-});
-console.log(zip.files);
-// will display:
-// - a/
-// - a/b/
-// - a/b/c/
-// - a/b/c/d.txt
-
-
-zip.file("a/b/c/d.txt", "content", {
-    createFolders: false
-});
-console.log(zip.files);
-// will display:
-// - a/b/c/d.txt
-```
-
-### `unixPermissions` and `dosPermissions` options
-
-Each permission will be used for matching [platform option of generateAsync()]({{site.baseurl}}/documentation/api_jszip/generate_async.html):
-on `DOS`, use `dosPermissions`, on `UNIX`, use `unixPermissions`.
-
-On nodejs you can use the `mode` attribute of
-[nodejs' fs.Stats](http://nodejs.org/api/fs.html#fs_class_fs_stats).
-
-When not set, a default value will be generated:
-
-- `0100664` or `040775` for `UNIX`
-- standard file or standard directory for `DOS`
-
-The field `unixPermissions` also accepts a **string** representing the
-octal value: "644", "755", etc.
-
-```js
-zip.file("script.sh", "#!/bin/bash", {
-    unixPermissions: "755"
-});
-```
-
-
-### `dir` option
-
-If `dir` is true or if a permission says it's a folder, this entry be flagged
-as a folder and the content will be ignored.
-
-See also [folder(name)]({{site.baseurl}}/documentation/api_jszip/folder_name.html).
-
-```js
-zip.file("folder/", null, {
-    dir: true
-});
-```
-
-## Other examples
-
-```js
-zip.file("Hello.txt", "Hello World\n");
-
-// base64
-zip.file("smile.gif", "R0lGODdhBQAFAIACAAAAAP/eACwAAAAABQAFAAACCIwPkWerClIBADs=", {base64: true});
-// from an ajax call with xhr.responseType = 'arraybuffer'
-zip.file("smile.gif", arraybufferFromXhr);
-// or on nodejs
-zip.file("smile.gif", fs.readFileSync("smile.gif"));
-
-zip.file("Xmas.txt", "Ho ho ho !", {date : new Date("December 25, 2007 00:00:01")});
-zip.file("folder/file.txt", "file in folder");
-
-zip.file("animals.txt", "dog,platypus\n").file("people.txt", "james,sebastian\n");
-
-// result:
-// - Hello.txt
-// - smile.gif
-// - Xmas.txt
-// - animals.txt
-// - people.txt
-// - folder/
-// - folder/file.txt
-```

-onUpdate            | function |          | The optional function called on each internal update with the metadata. [More](#onupdate-callback).
-
-### `type` option
-
-Possible values for `type` :
-
-* `base64`: the result will be a string, the binary in a base64 form.
-* `binarystring` (or `string`, deprecated): the result will be a string in "binary" form, using 1 byte per char (2 bytes).
-* `array`: the result will be an Array of bytes (numbers between 0 and 255) containing the zip.
-* `uint8array`: the result will be a Uint8Array containing the zip. This requires a compatible browser.
-* `arraybuffer`: the result will be a ArrayBuffer containing the zip. This requires a compatible browser.
-* `blob`: the result will be a Blob containing the zip. This requires a compatible browser.
-* `nodebuffer`: the result will be a nodejs Buffer containing the zip. This requires nodejs.
-
-Note : when using type = "uint8array", "arraybuffer" or "blob", be sure to
-check if the browser supports it (you can use [`JSZip.support`]({{site.baseurl}}/documentation/api_jszip/support.html)).
-
-```js
-zip.generateAsync({type: "uint8array"}).then(function (u8) {
-    // ...
-});
-```
-
-### `compression` and `compressionOptions` options
-
-Available `compression` methods are `STORE` (no compression) and `DEFLATE`.
-
-The `compressionOptions` parameter depends on the compression type. With
-`STORE` (no compression), this parameter is ignored. With `DEFLATE`, you can
-give the compression level with `compressionOptions : {level:6}` (or any level
-between 1 (best speed) and 9 (best compression)).
-
-Note : if the entry is *already* compressed (coming from a compressed zip file),
-calling `generateAsync()` with a different compression level won't update the entry.
-The reason is simple : JSZip doesn't know how compressed the content was and
-how to match the compression level with the implementation we use.
-
-```js
-zip.generateAsync({
-    type: "blob",
-    compression: "DEFLATE",
-    compressionOptions: {
-        level: 9
-    }
-});
-```
-
-### `comment` option
-
-The zip format has no flag or field to give the encoding of this field and
-JSZip will use UTF-8. With non ASCII characters you might get encoding issues
-if the file archiver doesn't use UTF-8 (or the given encoding) to decode the
-comment.
-
-```js
-zip.generateAsync({
-    type: "blob",
-    comment: "The comment text for this zip file"
-})
-```
-
-### `mimeType` option
-
-This field is used when you generate a Blob and need to change
-[the mime type](https://developer.mozilla.org/en-US/docs/Web/API/Blob/type).
-Useful when you need to generate a file with a different extension, ie: ".ods".
-
-Note, this won't change the content of the file, only the other programs *may*
-see it.
-
-```js
-//This example will Generate a Open Document Spreadsheet, with the correct mime type
-var zip = new JSZip();
-zip.file("mimetype", "application/vnd.oasis.opendocument.spreadsheet");
-var metaInf = zip.folder("META-INF");
-metaInf.file("manifest.xml", "<...");
-// ...
-
-//Generate the file
-zip.generateAsync({
-    type: "blob",
-    mimeType: "application/ods",
-    compression: "DEFLATE"
-}).then(function (odsFile) {
-    // odsFile.type == "application/ods"
-});
-```
-
-### `platform` option
-
-Possible values for `platform` : `DOS` and `UNIX`. It also accepts nodejs
-`process.platform` values.
-When using `DOS`, the attribute `dosPermissions` of each file is used.
-When using `UNIX`, the attribute `unixPermissions` of each file is used.
-
-If you set the platform value on nodejs, be sure to use `process.platform`.
-`fs.stats` returns a non executable mode for folders on windows, if you
-force the platform to `UNIX` the generated zip file will have a strange
-behavior on UNIX platforms.
-
-```js
-// on nodejs
-zip.file(pathname, content, {
-    date: stat.mtime,
-    unixPermissions: stat.mode
-});
-
-// ...
-
-zip.generateAsync({
-    type: 'nodebuffer',
-    platform: process.platform
-});
-```
-
-### `encodeFileName` option
-
-By default, JSZip uses UTF-8 to encode the file names / comments. You can use
-this method to force an other encoding. Note: the encoding used is not stored
-in a zip file, not using UTF-8 may lead to encoding issues.
-The function takes a string and returns a bytes array (Uint8Array or Array).
-
-See also [`decodeFileName` on `JSZip#loadAsync()`]({{site.baseurl}}/documentation/api_jszip/load_async.html#decodefilename-option).
-
-```js
-// using iconv-lite for example
-var iconv = require('iconv-lite');
-
-zip.generateAsync({
-    type: 'uint8array',
-    encodeFileName: function (string) {
-        return iconv.encode(string, 'your-encoding');
-    }
-});
-```
-
-
-### `streamFiles` option
-
-In a zip file, the size and the crc32 of the content are placed before the
-actual content: to write it we must process the whole file. When this option
-is `false` (the default) the processed file is held in memory. It takes more
-memory but generates a zip file which should be read by every program.
-When this options is `true`, we stream the file and use data descriptors at the
-end of the entry. This option uses less memory but some program might not
-support data descriptors (and won't accept the generated zip file).
-
-```js
-zip.generateAsync({
-    type: 'uint8array',
-    streamFiles: true
-});
-```
-
-### `onUpdate` callback
-
-If specified, this function will be called each time a chunk is pushed to the
-output stream (or internally accumulated).
-
-The function takes a `metadata` object which contains information about the
-ongoing process.
-
-__Metadata__ : the metadata are:
-
-name        | type   | description
-------------|--------|------------
-percent     | number | the percent of completion (a double between 0 and 100)
-currentFile | string | the name of the current file being processed, if any.
-
-```js
-zip.generateAsync({type:"blob"}, function updateCallback(metadata) {
-    console.log("progression: " + metadata.percent.toFixed(2) + " %");
-    if(metadata.currentFile) {
-        console.log("current file = " + metadata.currentFile);
-    }
-})
-```
-
-## Other examples
-
-```js
-zip.generateAsync({type:"blob"})
-.then(function (content) {
-    // see FileSaver.js
-    saveAs(content, "hello.zip");
-});
-```
-
-```js
-zip.generateAsync({type:"base64"})
-.then(function (content) {
-    location.href="data:application/zip;base64,"+content;
-});
-```
-
-```js
-zip.folder("folder_1").folder("folder_2").file("hello.txt", "hello");
-// zip now contains:
-// folder_1/
-// folder_1/folder_2/
-// folder_1/folder_2/hello.txt
-
-zip.folder("folder_1").generateAsync({type:"nodebuffer"})
-.then(function (content) {
-    // relative to folder_1/, this file only contains:
-    // folder_2/
-    // folder_2/hello.txt
-    require("fs").writeFile("hello.zip", content, function(err){/*...*/});
-});

-Read an existing zip and merge the data in the current JSZip
-object at the current folder level. This technique has some limitations, see
-[here]({{site.baseurl}}/documentation/limitations.html).
-If the JSZip object already contains entries, new entries will be merged. If
-two have the same name, the loaded one will replace the other.
-
-Since v3.8.0 this method will santize relative path components (i.e. `..`) in loaded filenames to avoid ["zip slip" attacks](https://snyk.io/research/zip-slip-vulnerability). For example: `../../../example.txt` → `example.txt`, `src/images/../example.txt` → `src/example.txt`. The original filename is available on each zip entry as `unsafeOriginalName`.
-
-__Returns__ : A [Promise](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise) with the updated zip object.
-The promise can fail if the loaded data is not valid zip data or if it
-uses unsupported features (multi volume, password protected, etc).
-
-__Since__: v3.0.0
-
-## Arguments

--------------------|--------|------------
-data               | String/Array of bytes/ArrayBuffer/Uint8Array/Buffer/Blob/Promise | the zip file

-------------------------------|---------|---------|------------
-options.base64                | boolean | false   | set to `true` if the data is base64 encoded, `false` for binary. [More](#base64-option).
-options.checkCRC32            | boolean | false   | set to `true` if the read data should be checked against its CRC32. [More](#checkcrc32-option).
-options.optimizedBinaryString | boolean | false   | set to `true` if (and only if) the input is a string and has already been prepared with a 0xFF mask.
-options.createFolders         | boolean | false   | set to `true` to create folders in the file path automatically. Leaving it false will result in only virtual folders (i.e. folders that merely represent part of the file path) being created. [More](#createfolders-option).
-options.decodeFileName        | function | decode from UTF-8 | the function to decode the file name / comment. [More](#decodefilename-option).
-
-You shouldn't update the data given to this method : it is kept as it so any
-update will impact the stored data.
-
-Zip features supported by this method :
-
-* Compression (<code>DEFLATE</code> supported)
-* zip with data descriptor
-* ZIP64
-* UTF8 in file name, UTF8 in file content
-
-Zip features not (yet) supported :
-
-* password protected zip
-* multi-volume zip
-
-### `base64` option
-
-```js
-var zip = new JSZip();
-zip.loadAsync("UEsDBAoDAAAAAJxs8T...AAAAAA==", {base64: true});
-```
-
-### `checkCRC32` option
-
-The `checkCRC32` option will load every files, compute the CRC32 value and
-compare it against the saved value.
-With larger zip files, this option can have a significant performance cost.
-
-```js
-// here, "bin" is a corrupted zip file
-
-zip.loadAsync(bin)
-.then(function (zip) {
-    // will be called, even if content is corrupted
-}, function (e) {
-    // won't be called
-});
-
-zip.loadAsync(bin, {
-    checkCRC32: true
-})
-.then(function (zip) {
-    // won't be called
-}, function (e) {
-    // Error: Corrupted zip : CRC32 mismatch
-});
-```
-
-### `createFolders` option
-
-```js
-// here, "bin" is zip file containing:
-// folder1/folder2/folder3/file1.txt
-
-zip.loadAsync(bin)
-.then(function (zip) {
-    console.log(zip.files);
-    // folder1/folder2/folder3/file1.txt
-});
-
-// with createFolders: true, all folders will be created
-zip.loadAsync(bin, {createFolders: true})
-.then(function (zip) {
-    console.log(zip.files);
-    // folder1/
-    // folder1/folder2/
-    // folder1/folder2/folder3/
-    // folder1/folder2/folder3/file1.txt
-});
-```
-
-### `decodeFileName` option
-
-A zip file has a flag to say if the filename and comment are encoded with UTF-8.
-If it's not set, JSZip has **no way** to know the encoding used. It usually
-is the default encoding of the operating system. Some extra fields can give
-the unicode version of the filename/comment too (in that case, we use it).
-
-If we can't find an UTF-8 encoded filename/comment, we use the `decodeFileName`
-function (which is by default an UTF-8 decode).
-
-The function takes the bytes array (Uint8Array or Array) and returns the
-decoded string.
-
-```js
-// here, "bin" is a russian zip file, using the cp866 encoding for file names
-// by default, using UTF-8 leads to wrong file names:
-zip.loadAsync(bin)
-.then(function (zip) {
-    console.log(zip.files);
-    // '����� �����/': ...
-    // '����� �����/����� ⥪�⮢�� ���㬥��.txt': ...
-});
-
-// using the correct encoding solve the issue:
-var iconv = require('iconv-lite');
-zip.loadAsync(bin, {
-  decodeFileName: function (bytes) {
-    return iconv.decode(bytes, 'cp866');
-  }
-})
-.then(function (zip) {
-    console.log(zip.files);
-    // 'Новая папка/': ...
-    // 'Новая папка/Новый текстовый документ.txt': ...
-});
-```
-
-## Other examples
-
-```js
-var zip = new JSZip();
-zip.loadAsync(zipDataFromXHR);
-```
-
-```js
-require("fs").readFile("hello.zip", function (err, data) {
-  if (err) throw err;
-  var zip = new JSZip();
-  zip.loadAsync(data);
-}
-```
-
-Using sub folders :
-
-```js
-// here, "bin" is zip file containing:
-// file1.txt
-// folder1/file2.txt
-
-var zip = new JSZip();
-zip.folder("subfolder").loadAsync(bin)
-.then(function (zip) {
-    // "zip" is still in the "subfolder" folder
-    console.log(zip.files);
-    // subfolder/file1.txt
-    // subfolder/folder1/file2.txt
-});
-```
-
-Using `loadAsync` multiple times:
-
-```js
-// here, "bin1" is zip file containing:
-// file1.txt
-// file2.txt
-// and "bin2" is zip file containing:
-// file2.txt
-// file3.txt
-
-var zip = new JSZip();
-zip.loadAsync(bin1)
-.then(function (zip) {
-    return zip.loadAsync(bin2);
-}).then(function (zip) {
-    console.log(zip.files);
-    // file1.txt, from bin1
-    // file2.txt, from bin2
-    // file3.txt, from bin2
-});
-```
-
-Reading a zip file with relative filenames:
-
-```js
-// here, "unsafe.zip" is zip file containing:
-// src/images/../file.txt
-// ../../example.txt
-
-require("fs").readFile("unsafe.zip", function (err, data) {
-    if (err) throw err;
-    var zip = new JSZip();
-    zip.loadAsync(data)
-    .then(function (zip) {
-        console.log(zip.files);
-        // src/file.txt
-        // example.txt
-        console.log(zip.files["example.txt"].unsafeOriginalName);
-        // "../../example.txt"
-    });

-
-__Returns__ : The current StreamHelper object, for chaining.
-
-__Throws__ : An exception if the event is unknown.
-
-## Arguments
-
-name      | type     | description
-----------|----------|------------
-event     | string   | the name of the event. Only 3 events are supported : `data`, `end` and `error`.
-callback  | function | the function called when the event occurs. See below for the arguments.
-
-The callbacks are executed in with the current `StreamHelper` as `this`.
-
-### `data` callback
-
-It takes 2 parameters:
-
-- the current chunk of data (in a format specified by the method which
-  generated this StreamHelper)
-- the metadata (see each method to know what's inside)
-
-### `end` callback
-
-It does not take any parameter.
-
-### `error` callback
-
-It takes an `Error` as parameter.
-
-## Example
-
-```js
-zip
-.generateInternalStream({type:"uint8array"})
-.on('data', function (data, metadata) {
-    // data is a Uint8Array because that's the type asked in generateInternalStream
-    // metadata contains for example currentFile and percent, see the generateInternalStream doc.
-})
-.on('error', function (e) {
-    // e is the error
-})
-.on('end', function () {
-    // no parameter
-})
-.resume();
-```

-
-## Arguments
-
-name     | type     | description
----------|----------|------------
-type     | String   | the type of the result. [More](#type-option).
-onUpdate | Function | an optional function called on each internal update with the metadata. [More](#onupdate-callback).
-
-### `type` option
-
-Possible values for `type` :
-
-* `base64` : the result will be a string, the binary in a base64 form.
-* `text` (or `string`): the result will be an unicode string.
-* `binarystring`: the result will be a string in "binary" form, using 1 byte per char (2 bytes).
-* `array`: the result will be an Array of bytes (numbers between 0 and 255).
-* `uint8array` : the result will be a Uint8Array. This requires a compatible browser.
-* `arraybuffer` : the result will be a ArrayBuffer. This requires a compatible browser.
-* `blob` : the result will be a Blob. This requires a compatible browser.
-* `nodebuffer` : the result will be a nodejs Buffer. This requires nodejs.
-
-Note : when using type = "uint8array", "arraybuffer" or "blob", be sure to
-check if the browser supports it (you can use [`JSZip.support`]({{site.baseurl}}/documentation/api_jszip/support.html)).
-
-```js
-zip.file("image.png").async("uint8array").then(function (u8) {
-    // ...
-});
-```
-
-### `onUpdate` callback
-
-If specified, this function will be called each time a chunk is pushed to the
-output stream (or internally accumulated).
-
-The function takes a `metadata` object which contains information about the
-ongoing process.
-
-__Metadata__ : the metadata are :
-
-name        | type   | description
-------------|--------|------------
-percent     | number | the percent of completion (a double between 0 and 100)
-
-```js
-zip.file("image.png").async("uint8array", function updateCallback(metadata) {
-    console.log("progression: " + metadata.percent.toFixed(2) + " %");
-}).then(function (u8) {
-    // ...
-})
-```
-
-
-## Other examples
-
-```js
-zip
-.file("my_text.txt")
-.async("string")
-.then(function success(content) {
-    // use the content
-}, function error(e) {

-
-### Download the sources
-
-You should create a [Github](https://github.com/) account and
-[fork the repository](https://help.github.com/articles/fork-a-repo) (you will
-need one to create the pull request).
-
-If you just want the get the source code, you can use git and do
-`git clone https://github.com/Stuk/jszip.git` to get the sources. You can also
-download the latest sources [here](https://github.com/Stuk/jszip/archive/main.zip).
-
-### Building the project
-
-#### Code
-
-The dependencies are handled by npm, the first step is to run
-`npm install` to get the dependencies.
-JSZip uses Grunt to handle the build, [see here to install its CLI](http://gruntjs.com/getting-started).
-
-Here are the interesting build commands :
-
-* `grunt` will generate the final js file in dist/ and the minified version.
-* `npm run test-node` will run the tests in nodejs.
-* `npm run test-browser` will the tests in some browsers using SauceLabs, see
-  below.
-* `npm run test` will run the tests in nodejs and in the browser.
-* `npm run lint` will use eslint the check the source code.
-
-#### Documentation
-
-The documentation uses jekyll on gh-pages. To render the documentation, you
-need to [install jekyll](http://jekyllrb.com/docs/installation/) and then run
-`jekyll serve --baseurl ''`.
-
-### Testing the project
-
-To test JSZip in nodejs, use `npm run test-node`.
-
-To test JSZip in a browser, you can open the file `test/index.html` in the
-browser you want to test. Don't forget to update the dist/ files with `grunt`.
-
-You can also test JSZip in a lot of browsers at once with
-[SauceLabs](https://saucelabs.com/). You will need a SauceLabs account and two
-variables into your environment. On linux, just use
-
-```bash
-export SAUCE_USERNAME=your-saucelabs-username
-export SAUCE_ACCESS_KEY=your-saucelabs-access-key
-```
-
-before running the `npm run test-browser` command.
-
-### Merging the changes
-
-If you have tested bug fixes or new features, you can open a
-[pull request](https://help.github.com/articles/using-pull-requests) on Github.
-
-## Releasing a new version
-
-1. In `package.json` temporarily remove `browser["./lib/index"]`.
-2. Run `npm test`
-    * Locally open http://localhost:8080/test/
-    * Or use the SauceLabs configuration above
-3. Update `JSZip.version` in `index.js`, `index.html` and in `package.json`
-4. Run `grunt` to generate the new dist files
-    * undo the package.json change, it was just needed to replace the `__VERSION__` in the header
-5. Undo step 1.
-6. Change version back in `package.json` (it will get update by the npm command below)
-7. Update CHANGES.md
-8. Commit the appropriate changes
-9. Run `npm version ...` where `...` is `major`, `minor`, or `patch`
-10. Run npm publish

-title: "How to use JSZip"
-layout: default
-section: example
----
-
-An instance of JSZip represents a set of files. You can add them, remove them,
-modify them. You can also import an existing zip file or generate one.
-
-### Getting the object
-
-#### In a browser
-
-For a browser, there are two interesting files : `dist/jszip.js` and
-`dist/jszip.min.js` (include just one).
-
-If you use an AMD loader (RequireJS for example) JSZip will register itself :
-you just have to put the js file at the right place, or configure the loader
-(see [here for RequireJS](http://requirejs.org/docs/api.html#config-paths)).
-
-Without any loader, JSZip will declare in the global scope a variable named `JSZip`.
-
-#### In nodejs
-
-In nodejs, you can `require` it :
-
-```js
-var JSZip = require("jszip");
-```
-
-### Basic manipulations
-
-The first step is to create an instance of JSZip :
-
-```js
-var zip = new JSZip();
-```
-
-On this instance, we can add (and update) files and folders with
-`.file(name, content)` and `.folder(name)`.
-They return the current JSZip instance so you can chain the calls.
-
-```js
-// create a file
-zip.file("hello.txt", "Hello[p my)6cxsw2q");
-// oops, cat on keyboard. Fixing !
-zip.file("hello.txt", "Hello World\n");
-
-// create a file and a folder
-zip.file("nested/hello.txt", "Hello World\n");
-// same as
-zip.folder("nested").file("hello.txt", "Hello World\n");
-```
-
-With `.folder(name)`, the returned object has a different root : if you add files
-on this object, you will put them in the created subfolder. This is just a
-view, the added files will also be in the "root" object.
-
-```js
-var photoZip = zip.folder("photos");
-// this call will create photos/README
-photoZip.file("README", "a folder with photos");
-```
-
-You can access the file content with `.file(name)` and
-[its getters]({{site.baseurl}}/documentation/api_zipobject.html) :
-
-```js
-zip.file("hello.txt").async("string").then(function (data) {
-  // data is "Hello World\n"
-});
-
-if (JSZip.support.uint8array) {
-  zip.file("hello.txt").async("uint8array").then(function (data) {
-    // data is Uint8Array { 0=72, 1=101, 2=108, more...}
-  });
-}
-```
-
-You can also remove files or folders with `.remove(name)` :
-
-```js
-zip.remove("photos/README");
-zip.remove("photos");
-// same as
-zip.remove("photos"); // by removing the folder, you also remove its content.
-```
-
-### Generate a zip file
-
-With `.generateAsync(options)` or `.generateNodeStream(options)` you can generate
-a zip file (not a real file but its representation in memory). Check
-[this page]({{site.baseurl}}/documentation/howto/write_zip.html) for more
-information on how to write / give the file to the user.
-
-```js
-var promise = null;
-if (JSZip.support.uint8array) {
-  promise = zip.generateAsync({type : "uint8array"});
-} else {
-  promise = zip.generateAsync({type : "string"});
-}
-```
-
-### Read a zip file
-
-With `.loadAsync(data)` you can load a zip file. Check
-[this page]({{site.baseurl}}/documentation/howto/read_zip.html) to see how to
-do properly (it's more tricky that it seems).
-
-```js
-var new_zip = new JSZip();
-// more files !
-new_zip.loadAsync(content)
-.then(function(zip) {
-    // you now have every files contained in the loaded zip
-    zip.file("hello.txt").async("string"); // a promise of "Hello World\n"
-});
-```

-
-### "Corrupted zip or bug: unexpected signature"
-
-If you are sure that the zip file is correct, that error often comes from a
-corrupted content. An ajax request, if not prepared correctly, will try to
-decode the binary content as a text and corrupt it. See
-[this page]({{site.baseurl}}/documentation/howto/read_zip.html).
-
-### My browser crashes / becomes unresponsive / never finish the execution
-
-That happens if you try to handle to much data with the synchronous API. If
-possible, try the asynchronous API, see
-[this page]({{site.baseurl}}/documentation/limitations.html) for more information.
-
-### Can't read the data of [...]. Is it in a supported JavaScript type ?
-
-Or the old message:
-
-> The data of [...] is in an unsupported format
-
-The method [`file(name, data [,options])`]({{site.baseurl}}/documentation/api_jszip/file_data.html)
-accepts string and binary inputs for `data`.
-
-If you use an unsupported type, an object for example, you will get this error:
-
-```js
-// WRONG
-var data = {
-    content: new ArrayBuffer(...)
-};
-zip.file("my.data", data); // won't work, data is an object
-
-// CORRECT
-var data = new ArrayBuffer(...);
-zip.file("my.data", data); // will work, JSZip accepts ArrayBuffer
-```
-
-### My mac generates a `.cpgz` file when I try to extract the zip file
-
-MacOS Finder has a lot of bug related to zip files (the `unzip` command line
-tool is fine). When something goes wrong, Finder will generate this cpgz file
-instead of showing an error.
-
-To get a correct result, try to enable compression in `generateAsync`:
-
-```js
-zip.generateAsync({
-    type:"...",
-    compression: "DEFLATE" // <-- here
-});
-```
-
-Using `platform: "UNIX"` may help too.

-title: "How to read a file"
-layout: default
-section: example
----
-
-This page explains how to read an existing zip file or add a existing file into
-the zip file.
-
-
-### In the browser
-
-#### AJAX request
-
-Getting binary data with an ajax request is hard (mainly because of IE <= 9).
-The easy way is to use [JSZipUtils.getBinaryContent](https://github.com/stuk/jszip-utils).
-With JSZipUtils.getBinaryContent, you can do the following (see the
-documentation for more examples) :
-
-```js
-JSZipUtils.getBinaryContent('path/to/content.zip', function(err, data) {
-    if(err) {
-        throw err; // or handle err
-    }
-
-    JSZip.loadAsync(data).then(function () {
-        // ...
-    });
-});
-
-// or, with promises:
-
-new JSZip.external.Promise(function (resolve, reject) {
-    JSZipUtils.getBinaryContent('path/to/content.zip', function(err, data) {
-        if (err) {
-            reject(err);
-        } else {
-            resolve(data);
-        }
-    });
-}).then(function (data) {
-    return JSZip.loadAsync(data);
-})
-.then(...)
-```
-
-<br>
-
-If you need to adapt an existing solution to what getBinaryContent does, here
-are the details. When doing a XHR request (level 1, without setting the
-`responseType`) the browser will try to interpret the response as a string and
-decode it from its charset. To avoid this on Firefox/Chrome/Opera, you need to
-set mime type : `xhr.overrideMimeType("text/plain; charset=x-user-defined");`.
-On IE <= 9, this is harder. The overrideMimeType trick doesn't work so we need
-to use [vbscript](http://stackoverflow.com/questions/1095102/how-do-i-load-binary-image-data-using-javascript-and-xmlhttprequest)
-and non standard attributes.
-On IE > 9, overrideMimeType doesn't work but xhr2 does.
-
-With [xhr 2](http://caniuse.com/xhr2), you can just set the responseType
-attribute : `xhr.responseType = "arraybuffer";`. With this, the browser will
-return an ArrayBuffer.
-
-#### Local files
-
-If the browser supports the [FileReader API](http://caniuse.com/filereader),
-you can use it to read a zip file. JSZip can read ArrayBuffer, so you can use
-`FileReader.readAsArrayBuffer(Blob)`, see this [example]({{site.baseurl}}/documentation/examples/read-local-file-api.html).
-
-### In nodejs
-
-JSZip can read Buffers so you can do the following :
-
-#### Local file
-
-```js
-"use strict";
-
-var fs = require("fs");
-var JSZip = require("jszip");
-
-// read a zip file
-fs.readFile("test.zip", function(err, data) {
-    if (err) throw err;
-    JSZip.loadAsync(data).then(function (zip) {
-        // ...
-    });
-});
-// or
-new JSZip.external.Promise(function (resolve, reject) {
-    fs.readFile("test.zip", function(err, data) {
-        if (err) {
-            reject(e);
-        } else {
-            resolve(data);
-        }
-    });
-}).then(function (data) {
-    return JSZip.loadAsync(data);
-})
-.then(...)
-
-
-// read a file and add it to a zip
-fs.readFile("picture.png", function(err, data) {
-    if (err) throw err;
-    var zip = new JSZip();
-    zip.file("picture.png", data);
-});
-// or
-var contentPromise = new JSZip.external.Promise(function (resolve, reject) {
-    fs.readFile("picture.png", function(err, data) {
-        if (err) {
-            reject(e);
-        } else {
-            resolve(data);
-        }
-    });
-});
-zip.file("picture.png", contentPromise);
-
-
-// read a file as a stream and add it to a zip
-var stream = fs.createReadStream("picture.png");
-zip.file("picture.png", stream);
-```
-
-#### Remote file
-
-There are a lot of nodejs libraries doing http requests, from the built-in
-[http](http://nodejs.org/docs/latest/api/http.html) to the
-[npm packages](https://www.npmjs.org/browse/keyword/http). Here are two
-examples, one with the default http API, the other with
-[request](https://github.com/mikeal/request) (but you're free to use your
-favorite library !). If possible, download the file as a Buffer (you will get
-better performances). If it's not possible, you can fallback to a binary string
-(the option is likely to be `encoding : "binary"`).
-
-##### With http :
-
-```js
-"use strict";
-
-var http = require("http");
-var url = require("url");
-var JSZip = require("jszip");
-
-var req = http.get(url.parse("http://localhost/.../file.zip"), function (res) {
-  if (res.statusCode !== 200) {
-    console.log(res.statusCode);
-    // handle error
-    return;
-  }
-  var data = [], dataLen = 0;
-
-  // don't set the encoding, it will break everything !
-  // or, if you must, set it to null. In that case the chunk will be a string.
-
-  res.on("data", function (chunk) {
-    data.push(chunk);
-    dataLen += chunk.length;
-  });
-
-  res.on("end", function () {
-    var buf = Buffer.concat(data);
-
-    // here we go !
-    JSZip.loadAsync(buf).then(function (zip) {
-      return zip.file("content.txt").async("string");
-    }).then(function (text) {
-      console.log(text);
-    });
-  });
-});
-
-req.on("error", function(err){
-  // handle error
-});
-```
-
-##### With request :
-
-```js
-"use strict";
-
-var request = require('request');
-var JSZip = require("jszip");
-
-request({
-  method : "GET",
-  url : "http://localhost/.../file.zip",
-  encoding: null // <- this one is important !
-}, function (error, response, body) {
-  if(error ||  response.statusCode !== 200) {
-    // handle error
-    return;
-  }
-  JSZip.loadAsync(body).then(function (zip) {
-    return zip.file("content.txt").async("string");
-  }).then(function (text) {
-    console.log(text);
-  });
-});
-```

-section: example
----
-
-### In the browser
-
-With only javascript, this part won't work in old browsers, including IE < 10.
-For those browsers, you can use a flash polyfill, see below.
-
-You can also see this
-[example]({{site.baseurl}}/documentation/examples/download-zip-file.html).
-
-#### Blob URL / FileSaver
-
-With recent browsers, the easiest way is to use `saveAs` or a polyfill, see
-[FileSaver.js](https://github.com/eligrey/FileSaver.js) :
-
-```js
-zip.generateAsync({type:"blob"})
-.then(function (blob) {
-    saveAs(blob, "hello.zip");
-});
-```
-
-Under the hood, the polyfill uses the native `saveAs` from the
-[FileSaver](http://www.w3.org/TR/file-writer-api/#the-filesaver-interface) API
-(on Chrome and IE10+) or use a [Blob URL](http://updates.html5rocks.com/2011/08/Downloading-resources-in-HTML5-a-download)
-(on Firefox).
-
-
-#### Data URI
-
-For older browsers that support [data URI](http://caniuse.com/datauri), you can also
-do the following :
-
-```js
-zip.generateAsync({type:"base64"}).then(function (base64) {
-    location.href="data:application/zip;base64," + base64;
-});
-```
-
-The biggest issue here is that the filenames are very awkward, Firefox
-generates filenames such as `a5sZQRsx.zip.part` (see bugs
-[367231](https://bugzilla.mozilla.org/show_bug.cgi?id=367231) and
-[532230](https://bugzilla.mozilla.org/show_bug.cgi?id=532230), and Safari
-isn't much better with just `Unknown`.
-
-Browser support and resulting filename :
-
-Opera  | Firefox | Safari | Chrome | Internet Explorer
--------|---------|--------|--------|------------------
-"default.zip" | random alphanumeric with ".part" extension | "Unknown" (no extension) | "download.zip" on OSX and Linux, just "download" on Windows | No
-
-#### Downloadify
-
-[Downloadify](https://github.com/dcneiner/downloadify) uses a small Flash SWF
-to download files to a user's computer with a filename that you can choose.
-Doug Neiner has added the `dataType` option to allow you to pass a zip for
-downloading. Follow the [Downloadify demo](http://pixelgraphics.us/downloadify/test.html)
-with the following changes:
-
-```js
-zip = new JSZip();
-zip.file("Hello.", "hello.txt");
-
-zip.generateAsync({type:"base64"}).then(function (base64) {
-    Downloadify.create('downloadify',{
-    ...
-    data: function(){
-        return base64;
-    },
-    ...
-    dataType: 'base64'
-    });
-});
-```
-
-<!--
-TODO : send data as GET / POST ?
--->
-
-#### Deprecated google gears
-
-[Franz Buchinger](http://www.picurl.org/blog/author/franz/) has written a
-brilliant tutorial on [using JSZip with Google Gears](http://www.picurl.org/blog/2009/11/22/creating-zip-archives-with-gears)
-([part 2](http://www.picurl.org/blog/2009/11/29/gearszipper-part2-adding-support-for-real-files-and-canvas-elements/)).
-If you want to let your Gears users download several files at once I really
-recommend having a look at some of his [examples](http://picurl.org/gears/zipper/).
-
-
-
-### In nodejs
-
-JSZip can generate Buffers so you can do the following :
-
-```js
-var fs = require("fs");
-var JSZip = require("jszip");
-
-var zip = new JSZip();
-// zip.file("file", content);
-// ... and other manipulations
-
-zip
-.generateNodeStream({type:'nodebuffer',streamFiles:true})
-.pipe(fs.createWriteStream('out.zip'))
-.on('finish', function () {
-    // JSZip generates a readable stream with a "end" event,
-    // but is piped here in a writable stream which emits a "finish" event.
-    console.log("out.zip written.");
-});
-```

-title: "Limitations of JSZip"
-layout: default
-section: limitations
-fullpage: true
----
-
-### Not supported features
-
-Not all features of zip files are supported. Classic zip files will work
-but encrypted zip, multi-volume, etc are not supported and the loadAsync()
-method will return a failed promise.
-
-
-### ZIP64 and 32bit integers
-
-ZIP64 files can be loaded, but only if the zip file is not "too big". ZIP64 uses 64bits integers
-but JavaScript represents all numbers as
-[64-bit double precision IEEE 754 floating point numbers](http://www.ecma-international.org/publications/files/ECMA-ST/ECMA-262.pdf)
-(see section 8.5). So, we have 53bits for integers and
-[bitwise operations treat everything as 32bits](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Bitwise_Operators).
-So if all the 64bits integers can fit into 32 bits integers, everything will be
-fine. If it's not the case, you will have other problems anyway (see next
-limitation).
-
-### Performance issues
-
-An other limitation comes from the browser (and the machine running the
-browser). A compressed zip file of 10MB is easily opened by firefox / chrome
-/ opera / IE10+ but will crash older IE. Also keep in mind that strings in
-javascript are encoded in UTF-16 : a 10MB ascii text file will take 20MB of
-memory.
-
-The
-[`async` method]({{site.baseurl}}/documentation/api_zipobject/async.html) and the
-[`generateAsync` method]({{site.baseurl}}/documentation/api_jszip/generate_async.html)
-hold the full result in memory but doesn't freeze the browser. If the result
-is too big, and if you can't use the
-[`nodeStream` method]({{site.baseurl}}/documentation/api_zipobject/node_stream.html) or the
-[`generateNodeStream` method]({{site.baseurl}}/documentation/api_jszip/generate_node_stream.html)
-you need to use the underlying
-[`StreamHelper`]({{site.baseurl}}/documentation/api_streamhelper.html) to
-handle the result chunk by chunk and `pause()`/`resume()` to handle the
-backpressure.
-
-If you're having performance issues, please consider the following :
-
-* Don't use IE &lt;= 9. Everything is better with typed arrays.
-* Use typed arrays (Uint8Array, ArrayBuffer, etc) if possible :
-  * If you generate a zip file, you should use `type:"uint8array"`
-    (or blob, arraybuffer, nodebuffer).
-  * If you load the file from an ajax call, ask your XHR an ArrayBuffer.
-    Loading a string is asking for troubles.
-
-Note about compression :
-When reading a file, JSZip will store the content without decompressing it.
-When generating a compressed file, JSZip will reuse if possible the compressed
-content :
-
-* If you read a zip file compressed with DEFLATE and call `generate` with the
-  DEFLATE compression, JSZip won't call the compression algorithms (same with
-  STORE everywhere.)
-* If you read a zip file compressed with DEFLATE and call `generate` with the
-  STORE compression, JSZip will have to decompress everything.
-
-On IE &lt;=9, typed arrays are not supported and the compression algorithm
-will fallback on arrays. In that case, JSZip needs to convert the binary string
-into an array, DEFLATE it and convert the result into a binary string.
-You don't want that to happen.
-
-### The output zip will differ from the input zip
-
-Reading and generating a zip file won't give you back the same file.
-Some data are discarded (file metadata) and other are added (subfolders).
-
-### Encodings support
-
-JSZip only supports UTF-8 natively. A zip file doesn't contain the name of the
-encoding used, you need to know it before doing anything.
-
-#### File name
-
-If the name of a file inside the zip is encoded with UTF-8 then JSZip can
-detect it (Language encoding flag, Unicode Path Extra Field). If not, JSZip
-can't detect the encoding used and will generate [Mojibake](https://en.wikipedia.org/wiki/Mojibake).
-You can use the [encodeFileName]({{site.baseurl}}/documentation/api_jszip/generate.html)
-option and the [decodeFileName]({{site.baseurl}}/documentation/api_jszip/load.html)
-option to encode/decode using a custom encoding.
-
-#### File content
-
-The `async("string")` method uses UTF-8 to decode the content. If you have a text in
-a different encoding, you can get the bytes array with `async("uint8array")` and
-decode it with a lib (iconv, iconv-lite, etc) on your side.
-To save a text using a non-UTF-8 encoding, do the same : encode it into a
-Uint8Array before adding it to JSZip.

-title: Upgrade Guide
-layout: default
-section: main
----
-
-### From 2.x to 3.0.0
-
-* Deprecated objects/methods has been removed:
-  * `options.base64` in `generate()` (the base64 type is still valid)
-  * `options.base64`, `options.binary`, `options.dir`, `options.date`
-    on `ZipObject` (see the [2.3 upgrade section](#from-222-to-230))
-  * `JSZip.utils`
-  * `JSZip.prototype.crc32`, `JSZip.prototype.utf8encode`, `JSZip.prototype.utf8decode`
-  * `JSZip.base64` (you can get the content of a file directly as a base64 string)
-* `JSZip.compressions` has been removed.
-* On `ZipObject`, the synchronous getters has been replaced by `async()` and
-  `nodeStream()`.
-* The `generate()` method has been replaced by `generateAsync()` and 
-  `generateNodeStream()`.
-* The `type` option in `generate()` is now mandatory.
-* The "text" type has been replaced by the "string" type, a binary string is
-  named "binarystring".
-* The `load()` method and the constructor with data (`new JSZip(data)`) have
-  been replaced by `loadAsync()`.
-* When adding a file, the option `createFolders` now defaults to `true`. If
-  you don't want to create sub folders, set it to false.
-* `zip.generateAsync()` and `zip.generateNodeStream()` now depend on the
-  current folder level.
-
-```js
-// 2.x
-zip.file("test.txt").asText();
-// 3.x
-zip.file("test.txt").async("string")
-.then(function (content) {
-    // use content
-});
-
-
-// 2.x
-zip.generate();
-// 3.x
-zip.generateAsync({type:"uint8array"})
-.then(function (content) {
-    // use content
-});
-
-// 2.x
-new JSZip(data);
-zip.load(data);
-// zip.file(...)
-// 3.x
-JSZip.loadAsync(data).then(zip) {...};
-zip.loadAsync(data).then(zip) {...};
-// here, zip won't have (yet) the updated content
-
-// 2.x
-var data = zip.file("img.jpg").asBinary();
-var dataURI = "data:image/jpeg;base64," + JSZip.base64.encode(data);
-// 3.x
-zip.file("img.jpg").async("base64")
-.then(function (data64) {
-    var dataURI = "data:image/jpeg;base64," + data64;
-});
-```
-
-`async` and `loadAsync` use (a polyfill of) promises, you can find
-the documentation [here](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise)
-and a tutorial [here](http://www.html5rocks.com/en/tutorials/es6/promises/).
-
-It is worth noting that:
-
-```js
-/*
- * JSZip accepts these promise as input
- */
-
-// replace a content with JSZip v2
-var content = zip.file("my_file").asText();
-content = content.replace(/apples/, 'oranges');
-zip.file("my_file", content);
-
-// replace a content with JSZip v3
-var contentPromise = zip.file("my_file").async("text").then(function (content) {
-    return content.replace(/apples/, 'oranges');
-});
-zip.file("my_file", contentPromise);
-
-
-/*
- * Promises are chainable
- */
-
-// read, update, generate a zip file with JSZip v2
-var zip = new JSZip(content);
-zip.file("new_file", "new_content");
-var blob = zip.generate({type: "blob"});
-saveAs(blob, "result.zip");
-
-// read, update, generate a zip file with JSZip v3
-JSZip.loadAsync(content)
-.then(function (zip) {
-    zip.file("new_file", "new_content");
-    // if you return the zip object, it will be available in the next "then"
-    return zip;
-.then(function (zip) {
-    // if you return a promise of a blob, promises will "merge": the current
-    // promise will wait for the other and the next "then" will get the
-    // blob
-    return zip.generateAsync({type: "blob"});
-.then(function (blob) {
-    saveAs(blob, "result.zip");
-});
-```
-
-### From 2.2.2 to 2.3.0
-
-* On `ZipObject#options`, the attributes `date` and `dir` have been
-  deprecated and are now on `ZipObject`.
-* On `ZipObject#options`, the attributes `base64` and `binary` have been
-  deprecated.
-* `JSZip.base64`, `JSZip.prototype.crc32`, `JSZip.prototype.utf8decode`,
-  `JSZip.prototype.utf8encode` and `JSZip.utils` have been deprecated.
-
-```js
-// deprecated
-zip.file("test.txt").options.date
-zip.file("test.txt").options.dir
-// new API
-zip.file("test.txt").date
-zip.file("test.txt").dir
-```
-
-
-### From 2.0.0 to 2.1.0
-
-* The packaging changed : instead of loading jszip.js, jszip-load.js,
-  jszip-inflate.js, jszip-deflate.js, just include dist/jszip.js or
-  dist/jszip.min.js.
-  For AMD loader users : JSZip now registers itself. You just have to put the
-  file at the right place or configure your loader.
-
-
-### From 1.x to 2.x
-
-* `JSZipBase64` has been renamed to `JSZip.base64`.
-* The `data` attribute doesn't exist anymore :
-  use the getters `asText()`, `asBinary()`, etc
-* The compression/decompression methods now give their input type with the
-  `compressInputType` and `uncompressInputType` attributes.
-
-Example for the data attribute :
-
-```js
-// before
-zip.file("test.txt").data;
-zip.files["test.txt"].data;
-zip.file("image.png").data;
-zip.files["image.png"].data;
-
-// after
-zip.file("test.txt").asText();
-zip.files["test.txt"].asText();
-zip.file("image.png").asBinary();
-zip.files["image.png"].asBinary();
-```
