+# Harminv Release Notes
+
+Here, we describe what has changed between releases of the [h5utils](README.md) package.
+
+## h5utils-1.13.1 ##
+
+*3/19/18*
+
+* Fixed man page problems (#2 and #3), thanks to Bas Couwenberg.
+
+## h5utils-1.13 ##
+
+*7/18/17*
+
+* Fixed `h5topng` compilation for modern libpng versions.  Thanks to
+  Daisuke Fujimura (@fd00 on github) for posting patches.
+
+* Moved hosting to Github and translated documentation to Markdown.
+
+## h5utils 1.12.1 ##
+
+*6/24/09*
+
+* Use `octave-config`, if available, to detect octave-plugin installation path (thanks to Debian bug report #516453 for suggestion).
+
+## h5utils 1.12 ##
+
+*6/12/09*
+
+* The vertical axis in `h5topng` is now reversed to correspond to what most people seem to expect: increasing coordinates correspond to "up" and "right" in the image, rather than "down" and "right" in the image as in previous versions.
+* Fixed failure in `h5tovtk -2`; thanks to Karen Lee for the bug report.
+* Fixed installation of `h5read.oct` for Octave 3.x.
+
+## h5utils 1.11.1 ##
+
+*4/28/08*
+
+* Fixed failure to find colormap files in h5topng 1.11 (due to changes in autoconf 2.60); thanks to bug report from Jiangjun Zheng.
+
+## h5utils 1.11 ##
+
+*4/24/08*
+
+* h5tovtk no longer reverses the dimensions; thanks to Andreas Wilde for the suggestion.
+* Fix compilation failure with HDF5 1.8.
+
+## h5utils 1.10.1 ##
+
+*9/20/06*
+
+* Fixed build problem on Cygwin due to missing "`.exe`" extension. Thanks to Ken Hill for the bug report.
+
+## h5utils 1.10 ##
+
+*9/2/05*
+
+* Added `h4fromh5` utility.  (NCSA seems to be no longer shipping the HDF5/HDF4 conversion tools with the latest HDF5 release.)
+* Added `dkbluered` color map, which is similar to `bluered` but uses a somewhat wider range of colors.
+
+## h5utils 1.9.1 ##
+
+*8/5/04*
+
+* Fix `h5topng` compilation failure with some non-C99 compilers; thanks to Maarten van Reeuwijk for the bug report.
+
+## h5utils 1.9 ##
+
+*7/12/04*
+
+* Added new `h5math` utility, which creates and combines HDF5 datasets using a user-specified mathematical expression. (Requires [GNU libmatheval](http://www.gnu.org/software/libmatheval/) to be installed.)
+* `h5topng`: Matlab-like `start:end` or `start:step:end` notation for slice indices, to allow a whole sequence of slices to be output as a sequence of PNG images.
+* `h5topng`: if contour/overlay dataset does not have same dimensions as output data, it is periodically "tiled" over the output.
+
+## h5utils 1.8 ##
+
+*5/22/04*
+
+* New `-A` and `-a` options for `h5topng` to allow translucent overlays from one file onto another (an alternative or complement to the `-C` contour-overlay option).
+* `h5topng` uses 24-bit direct color by default (use `-8` option for old 8-bit behavior).
+* `h5topng` uses columns/rows for x/y by default (use `-T` to swap), the opposite of the old behavior.
+* There is no default `-z 0` slice dimension in `h5topng`/`h5totxt` any more. You must specify a slice for 3+ dimensional data in `h5topng`. `h5totxt` dumps the whole data file by default unless one or more slices are specified.
+* Support specifying multiple slice dimensions for 4+ dimensional datasets, with new `-t` option to indicate final dimension.
+* Slices are also supported now in `h5tovtk` and `h5tov5d`.
+* New `-.` option in `h5totxt` to specify number of significant digits; output 16 digits by default instead of 6, previously.
+
+## h5utils 1.7.2 ##
+
+*7/15/02*
+
+* Fixed C++ compilation problem for `g++` 3.x in `h5read` Octave plugin; thanks to Josselin Mouette for the patch.
+
+## h5utils 1.7.1 ##
+
+*3/16/02*
+
+* Fixed array overrun in `h5topng` that caused a floating-point exception on Alphas; thanks to Marin Soljacic for the bug report.
+
+## h5utils 1.7 ##
+
+*3/9/02*
+
+* `h5topng` now supports multiple, user-definable color tables, a number of which are provided. '''Incompatible change''': the `-c` option now has the syntax: `-c ''colortable''`. The old behavior corresponds to the included "`bluered`" colortable, invoked via: `-c bluered`.
+* New `-R` option for `h5topng` to use a consistent color scale for all specified files.
+* New `-0` option for `h5topng` and `h5totxt` that shifts the origin of the slice coordinates to the dataset center.
+* Added `h5tovtk` program to output VTK (Visualization ToolKit) data files.
+* Support `-T` (transpose dimensions) option in `h5tov5d`.
+* Fixed bug in `h5topng` that caused extra rows/columns of garbage pixels to be written at the edges of images when scaling was used.
+* When compiling the h5read Octave plugin, respect the `CPPFLAGS` and `LDFLAGS` environment variables. Thanks to Max Colice for the bug report.
+* Fixed problem when `--without-h5tov5d` and `--without-h5fromh4` are used. Thanks to Nikola Ivanov Nikolov for the fix.
+
+## h5utils 1.6 ##
+
+*1/17/01*
+
+* Don't build `h5fromh4` if the superior `h4toh5` tool (from HDF5 1.4) is present. Also added `--{with,without}-h5fromh4` option to configure to force whether `h5fromh4` is built.
+
+## h5utils 1.5.1 ##
+
+*12/9/00*
+
+* Support manually disabling Octave plugin support (`configure --without-octave`) in case of C++ problems.
+* Support Vis5d+ and Debian HDF header file locations.
+
+## h5utils 1.5 ##
+
+*7/9/00*
+
+* Added `h5fromh4` program to convert HDF4 datasets to HDF5 format.
+* Added `-S ''s''` option to `h5topng` as a shortcut for `-X ''s'' -Y ''s''`.
+
+## h5utils 1.4 ##
+
+*5/28/00*
+
+* Added `h5fromtxt` program to convert text input to an HDF5 dataset.
+
+## h5utils 1.3.4 ##
+
+*1/31/00*
+
+* Improved -C contour plotting in h5topng.
+* Fix in `h5topng` man page (thanks to Christoph Becher).
+
+## h5utils 1.3.3 ##
+
+*1/30/00*
+
+* Bug fix in `h5topng` (would sometimes output solid black images). Thanks to Karl Koch for the bug report.
+
+## h5utils 1.3.2 ##
+
+*1/28/00*
+
+* Added `h5topng -Z` option to center color scale on zero.
+* Now support `h5topng -C ''filename:dataset''`.
+
+## h5utils 1.3.1 ##
+
+*1/27/00*
+
+* Bug fixes in dataset name-handling, especially when using `h5tov5d` to join multiple datasets into one output file.
+
+## h5utils 1.3 ##
+
+*1/21/00*
+
+* You can now specify individual datasets within a file by using ''filename'':''dataset'' instead of just ''filename'' with `h5topng`, `h5totxt`, and `h5tov5d`.
+
+## h5utils 1.2.3 ##
+
+*1/20/00*
+
+* Fixed minor bug in '`h5totxt -h`'.
+
+## h5utils 1.2.2 ##
+
+*1/12/00*
+
+* `Makefile` now includes `CPPFLAGS` in the compiler flags, making it easier to use header files in non-standard locations. (`CPPFLAGS` is the proper place to put `-I` flags for the configure script.)
+
+## h5utils 1.2.1 ##
+
+*1/1/00*
+
+* Modified `-o` option of `h5tov5d` to join datasets into a single Vis5d file.
+
+## h5utils 1.2 ##
+
+*12/31/99*
+
+* Added h5tov5d program for converting to Vis5d format.
+* Improved installation; `h5read.oct` now goes into the sitewide Octave plugins directory, and things work correctly when only some of the utilities are compiled.
+
+## h5utils 1.1 ##
+
+*12/6/99*
+
+* Added `h5totxt` program for exporting 2d slices of HDF5 files to text suitable for importing into a spreadsheet.
+
+## h5utils 1.0 ##
+
+*11/22/99*
+
+* Initial release.

+
+# H5utils
+
+**h5utils** is a set of utilities for visualization and conversion of scientific data in the free, portable [HDF5 format](http://www.hdfgroup.org/HDF5/).
+
+Besides providing a simple tool for batch visualization as [PNG](https://en.wikipedia.org/wiki/Portable_Network_Graphics) images, h5utils also includes programs to convert HDF5 datasets into the formats required by other free visualization software (e.g. plain text, [Vis5d](http://www.ssec.wisc.edu/~billh/vis5d.html), and [VTK](http://public.kitware.com/VTK/)).
+
+This package is developed by [Steven G. Johnson](http://math.mit.edu/~stevenj/), and is [free software](http://www.gnu.org/philosophy/free-sw.html) that should easily install under any Unix-like operating system (*e.g.* GNU/Linux).
+
+# Download and Install
+
+The latest version is h5utils 1.13.1, which can be downloaded in source-code form at:
+
+* https://github.com/NanoComp/h5utils/releases/download/1.13.1/h5utils-1.13.1.tar.gz
+
+(Download this `.tar.gz` file rather than cloning the [git repo](https://github.com/NanoComp/h5utils)
+unless you are a developer, since the git repo requires additional tools to build as described below.)
+
+What's new in each version is described in the [release notes](NEWS.md) file.
+
+h5utils is free software (a.k.a. [open source](http://www.opensource.org/)); see below for the license and copyright.
+
+## Installation
+
+h5utils is designed for Unix-like operating systems (*e.g.* GNU/Linux). We do not support Windows directly, although you may be able to install there too using free packages like [Cygwin](http://cygwin.com/).
+
+You must first download and install [HDF5](http://www.hdfgroup.org/HDF5/), if it is not already on your system. Also, the programs to convert (see below) to/from [PNG](http://www.libpng.org/pub/png/), [Vis5d](http://www.ssec.wisc.edu/~billh/vis5d.html), [GNU Octave](http://www.octave.org/), and [HDF(4)](http://www.hdfgroup.org/products/hdf4/) will only be built if the corresponding libraries/programs are installed. `h5math` will only be built if [GNU libmatheval](http://www.gnu.org/software/libmatheval/) is installed.
+
+To compile and install the package, you then just type the usual GNU build commands:
+```
+./configure
+make
+make install
+```
+See `./configure --help` for more options. You can use `make uninstall` to get rid of all the installed files.
+
+**Github**: If you are using the source [on github](https://github.com/NanoComp/h5utils) (via `git clone https://github.com/NanoComp/h5utils`), then you will also need to have [GNU autoconf, automake, and libtool](https://en.wikipedia.org/wiki/GNU_Build_System) installed, and run `sh autogen.sh` (in a Unix shell) to set up things before running `make` above (`autogen.sh` runs `./configure` for you).
+
+**Note:** if you get a message like `cannot compute sizeof (unsigned long)` when running `./configure`, it probably means you didn't install the HDF5 library properly: you need to tell the runtime linker where to find it. On GNU/Linux, make sure there is a line `/usr/local/lib` in `/etc/ld.so.conf` and run `/sbin/ldconfig` (assuming you installed HDF5 in the default location).
+
+*Note:* if you installed the [MPI](https://en.wikipedia.org/wiki/Message_Passing_Interface) (parallel) version of HDF5, you may get an error like `/usr/include/H5public.h:53:20: error: mpi.h: No such file or directory`.  This can be fixed by telling the compiler where to find the MPI header files, e.g. via: `./configure CC=mpicc`.
+
+# h5utils Programs
+
+The included utilities are:
+
+* **h5totxt** and **h5fromtxt**: convert HDF5 datasets to/from ASCII text (e.g. comma- or tab-delimited). See the manual pages of [h5totxt](doc/h5totxt-man.md) and [h5fromtxt](doc/h5fromtxt-man.md) for more information.
+* **h5topng**: convert 2d slices of HDF5 datasets to PNG images, with a variety of color tables and other options. See the [h5topng manual page](doc/h5topng-man.md) for more information.   See [Color tables in h5topng](doc/h5topng-colors.md) for information on the color tables.
+* **h5tov5d**: convert HDF5 datasets to the format used by the free 3d+ visualization tool [Vis5d](http://www.ssec.wisc.edu/~billh/vis5d.html). See the [manual page](doc/h5tov5d-man.md) for more information.  **Note**: to install h5tov5d you must have first compiled Vis5d, and you must specify `--with-v5d=dir` to the h5utils `configure` script to specify the location `dir` of the Vis5d source directory.
+* **h5tovtk**: convert HDF5 datasets to VTK format for use by the free [Visualization ToolKit](http://public.kitware.com/VTK/) (along with supporting programs like [MayaVi](http://mayavi.sourceforge.net/)). See the [manual page](doc/h5tovtk-man.md) for more information.
+* **h5math**: create and combine HDF5 datasets with simple (pointwise) mathematical expressions. (Requires [GNU libmatheval](http://www.gnu.org/software/libmatheval/) to be installed.) See the [manual page](doc/h5math-man.md) for more information.
+* **h5read.oct**: a plug-in for [GNU Octave](http://www.octave.org/) (a Matlab-like program) to read 2d slices of HDF5 datasets. (Recent versions of Octave also include native support for HDF5, although it can't read slices like the `h5read` plug-in.)
+* **h5fromh4** and **h4fromh5**: convert HDF (version 4) datasets to and from HDF5. These utilities are nowadays somewhat redundant with the [h4toh5](http://hdfgroup.com/h4toh5/) and `h5toh4` programs provided by NCSA and the HDF Group (which are no longer bundled with HDF5, however). See the [h5fromh4](doc/h5fromh4-man.md) and [h4fromh5](doc/h4fromh5-man.md) manual pages for more information.
+
+To convert HDF5 to [CDF](http://nssdc.gsfc.nasa.gov/cdf/cdf_home.html) format, see the [hdf5-to-cdf](http://nssdc.gsfc.nasa.gov/cdf/html/FAQ.html#hdf5tocdf) program.

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
-# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory.  The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-#    fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-#    fails if $ac_aux_dir is absolute,
-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is '.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
-#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-#   MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH.  The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

-\`configure' configures h5utils 1.13.1 to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking ...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
-
-Installation directories:
-  --prefix=PREFIX         install architecture-independent files in PREFIX
-                          [$ac_default_prefix]
-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-                          [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
-  --bindir=DIR            user executables [EPREFIX/bin]
-  --sbindir=DIR           system admin executables [EPREFIX/sbin]
-  --libexecdir=DIR        program executables [EPREFIX/libexec]
-  --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
-  --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
-  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
-  --libdir=DIR            object code libraries [EPREFIX/lib]
-  --includedir=DIR        C header files [PREFIX/include]
-  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
-  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]

-  --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
-  --enable-silent-rules   less verbose build output (undo: "make V=1")
-  --disable-silent-rules  verbose build output (undo: "make V=0")
-  --enable-maintainer-mode

-  --without-octave        don't compile h5read Octave plugin
-  --with-v5d=<dir>        use Vis5d in <dir> for h5tov5d
-
-Some influential environment variables:
-  CC          C compiler command
-  CFLAGS      C compiler flags
-  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
-              nonstandard directory <lib dir>
-  LIBS        libraries to pass to the linker, e.g. -l<library>
-  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
-              you have headers in a nonstandard directory <include dir>
-  CPP         C preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.
-
-Report bugs to <stevenj@alum.mit.edu>.

-## is deleted, the dependency causes make to die (because there is
-## typically no way to rebuild the header).  We avoid this by adding
-## dummy dependencies for each header file.  Too bad gcc doesn't do
-## this for us directly.
-## Some versions of gcc put a space before the ':'.  On the theory
-## that the space means something, we add a space to the output as
-## well.  hp depmode also adds that space, but also prefixes the VPATH

+# h4fromh5: convert HDF5 scientific dataset to an HDF4 file
+
+## Synopsis
+
+    h4fromh5[OPTION]... [HDF4FILE]...
+
+## Description
+
+`h4fromh5` takes one or more files in HDF5 format and outputs files in HDF4 format containing the datasets from the HDF5 files. (Currently, only a single dataset per HDF5 file is converted.)
+
+HDF4 and HDF5 are free, portable binary formats and supporting libraries developed by the National Center for Supercomputing Applications at the University of Illinois in Urbana-Champaign.
+
+A single
+HDF5 (`.h5`) file can contain multiple data sets; by default, `h4fromh5` converts the first dataset, but this can be changed via the `-d` option, or by using the syntax `HDF5FILE:DATASET`.
+
+The most basic usage is something like `h4fromh5 foo.h5`, which will output a file `foo.hdf` containing the scientific dataset from `foo.h5`.
+
+## Options
+
+* `-h` — Display help on the command-line options and usage.
+* `-V` — Print the version number and copyright info for `h4fromh5`.
+* `-v` — Verbose output.
+* `-T` — Transpose the output dataset (e.g. LxMxN becomes NxMxL). This is often useful because HDF5 programs typically follow C (row-major) conventions while HDF4 programs often follow Fortran (column-major, transposed) conventions for array ordering.
+* `-o file` — Send HDF output to `file` rather than to the input filename with `.h5` replaced with `.hdf` (the default).
+* `-d name` — Read from dataset `name` in the input; otherwise, the first dataset in the input file is used. Alternatively, use the syntax `HDF5FILE:DATASET` when the input file names are specified.

+# h5fromtxt: convert text input to an HDF5 file
+
+## Synopsis
+
+    h5fromtxt [OPTION]... [HDF5FILE]
+
+## Description
+
+`h5fromtxt` takes a series of numbers from standard input and outputs a multi-dimensional numeric dataset in an HDF5 file.
+
+HDF5 is a free, portable binary format and supporting library developed by the National Center for Supercomputing Applications at the University of Illinois in Urbana-Champaign. A single `.h5` file can contain multiple data sets; by default, `h5fromtxt` creates a dataset called "data", but this can be changed via the `-d` option, or by using the syntax `HDF5FILE:DATASET`. The `-a` option can be used to append new datasets to an existing HDF5 file.
+
+All characters besides the numbers (and associated decimal points, etcetera) in the input are ignored. By default, the data is assumed to be a two-dimensional MxN dataset where M is the number of rows (delimited by newlines) and N is the number of columns. In this case, it is an error for the number of columns to vary between rows. If M or N is 1 then the data is written as a one-dimensional dataset.
+
+Alternatively, you can specify the dimensions of the data explicitly via the `-n` `size` option, where `size` is e.g. "2x2x2". In this case, newlines are ignored and the data is taken as an array of the given size stored in row-major ("C") order (where the last index varies most quickly as you step through the data). e.g. a 2x2x2 array would be have the elements listed in the order: (0,0,0), (0,0,1), (0,1,0), (0,1,1), (1,0,0), (1,0,1), (1,1,0), (1,1,1).
+
+A simple example is:
+
+```
+h5fromtxt foo.h5 <<EOF — 
+1 2 3 4
+5 6 7 8
+EOF
+```
+
+which reads in a 2x4 space-delimited array from standard input.
+
+## Options
+
+* `-h` — Display help on the command-line options and usage.
+
+* `-V` — Print the version number and copyright info for `h5fromtxt`.
+
+* `-v` — Verbose output.
+
+* `-a` — If the HDF5 output file already exists, append the data as a new dataset rather than overwriting the file (the default behavior). An existing dataset of the same name within the file is overwritten, however.
+
+* `-n size` — Instead of trying to infer the dimensions of the array from the rows and columns of the input, treat the data as a sequence of numbers in row-major order forming an array of dimensions `size`. `size` is of the form MxNxLx... (with M, N, L being numbers) and may be of any dimensionality.
+
+* `-T` — Transpose the input when it is written, reversing the dimensions.
+
+* `-d name` — Write to dataset `name` in the output; otherwise, the output dataset is called "data" by default. Alternatively, use the syntax `HDF5FILE:DATASET`.

+# h5math: combine/create HDF5 files with math expressions
+
+## Synopsis
+
+    h5math [OPTION]... OUTPUT-HDF5FILE [INPUT-HDF5FILES...]
+
+## Description
+
+`h5math` takes any number of HDF5 files as input, along with a mathematical expression, and combines them to produce a new HDF5 file.
+
+HDF5 is a free, portable binary format and supporting library developed by the National Center for Supercomputing Applications at the University of Illinois in Urbana-Champaign. A single `.h5` file can contain multiple data sets; by default, `h5math` creates a dataset called "h5math", but this can be changed via the `-d` option, or by using the syntax `HDF5FILE:DATASET`. The `-a` option can be used to append new datasets to an existing HDF5 file. The same syntax is used to specify the dataset used in the input file(s); by default, the first dataset (alphabetically) is used.
+
+A simple example of `h5math` usage is:
+
+    h5math -e "d1 + 2*d2" out.h5 foo.h5 bar.h5:blah
+
+which produces a new file, `out.h5`, by adding the first dataset in `foo.h5` with twice the `blah` dataset in `bar.h5`. In the expression (specified by `-e`), the first input dataset (from left to right) is referred to as `d1`, the second as `d2`, and so on.
+
+In addition to input datasets, you can also use the x/y/z coordinates of each point in the expression, referenced by `x y` and `z` variables (for the first three dimensions) as well as a `t` variable that refers to the last dimension. By default, these are integers starting at 0 at the corner of the dataset, but the `-0` option will change the x/y/z origin to the center of the dataset (t is unaffected), and the `-r res` option will specify the "resolution", dividing the x/y/z coordinates by `res`.
+
+All of the input datasets must have the same dimensions, which are also the dimensions of the output. If there are no input files, and you are defining the output purely by a mathematical formula, you can specify the dimensions of the output explicitly via the `-n size` option, where `size` is e.g. "2x2x2".
+
+Sometimes, however, you want to use only a smaller-dimensional "slice" of multi-dimensional data. To do this, you specify coordinates in one (or more) slice dimension(s), via the `-xyzt` options.
+
+## Options
+
+* `-h` — Display help on the command-line options and usage.
+
+* `-V` — Print the version number and copyright info for `h5math`.
+
+* `-v` — Verbose output.
+
+* `-a` — If the HDF5 output file already exists, append the data as a new dataset rather than overwriting the file (the default behavior). An existing dataset of the same name within the file is overwritten, however.
+
+* `-e expression` — Specify the mathematical expression that is used to construct the output (generally in `"` quotes to group the expression as one item in the shell), in terms of the variables for the input datasets and the coordinates as described above.
+ - Expressions use a C-like infix notation, with most standard operators and mathematical functions (`+`, `sin`, etc.) being supported. This functionality is provided (and its features determined) by [GNU libmatheval](https://www.gnu.org/software/libmatheval/).
+
+* `-f filename` — Name of a text file to read the expression from, if no `-e` expression is specified. Defaults to stdin.
+
+* `-x ix`, `-y iy`, `-z iz`, `-t it` — This tells `h5math` to use a particular slice of a multi-dimensional dataset. e.g. `-x` uses the subset (with one less dimension) at an x index of `ix` (where the indices run from zero to one less than the maximum index in that direction). Here, x/y/z correspond to the first/second/third dimensions of the HDF5 dataset. The `-t` option specifies a slice in the last dimension, whichever that might be. See also the `-0` option to shift the origin of the x/y/z slice coordinates to the dataset center.
+
+* `-0` — Shift the origin of the x/y/z slice coordinates to the dataset center, so that e.g. -0 -x 0 (or more compactly -0x0) returns the central x plane of the dataset instead of the edge x plane. (`-t` coordinates are not affected.) This also shifts the origin of the x/y/z variables in the expression so that 0 is the center of the dataset.
+
+* `-r res` — Use a resolution `res` for x/y/z (but not t) variables in the expression, so that the data "grid" coordinates are divided by `res`. The default `res` is 1.
+ - For example, if the x dimension has 21 grid steps, setting a `res` of 20 will mean that x variables in the expression run from 0.0 to 1.0 (or -0.5 to 0.5 if `-0` is specified), instead of 0 to 20.
+ - `-r` does not affect the coordinates used for slices, which are always integers.
+
+* `-n size` — The output dataset must be the same size as the input datasets. If there are no input datasets (if you are defining the output purely by a formula), then you must specify the output size manually with this option: `size` is of the form MxNxLx… (with M, N, L being integers) and may be of any dimensionality.
+
+* `-d name` — Write to dataset `name` in the output; otherwise, the output dataset is called "data" by default. Also use dataset `name` in the input; otherwise, the first input dataset (alphabetically) in a file is used. Alternatively, use the syntax `HDF5FILE:DATASET` (which overrides the `-d` option).

+# Color tables in h5topng
+
+The `h5topng` utility program contains a number of built-in color tables that you can use for plotting data.  These color tables are listed below, in some cases with notes about where they came from or suggested usage.
+
+## Color tables
+The color scales that I would tend to recommend are the following five, taken from [the Matplotlib colormaps](https://matplotlib.org/users/colormaps.html):
+
+* `viridis`: ![viridis](images/viridis.png)
+ - the default blue-green-yellow colormap in Matplotlib, a nice sequential colormap
+* `RdBu`: ![RdBu](images/RdBu.png)
+ - red-white-blue colormap, good for signed data in conjunction with `-Z` option to make white=0
+* `inferno`: ![inferno](images/inferno.png)
+  - a black-purple-red-orange-yellow colormap, a good replacement for the old `hot` colormap
+ * `BrBG`: ![BrBG](images/BrBG.png)
+  - brown-white-aquamarine colormap, an alternative to `RdBu` for signed data, also best used in conjunction with the `-Z` option to make white=0
+
+These two are also sometimes useful:
+
+* `gray`:  ![gray](images/Gray_colormap.png)
+ - simple black-to-white grayscale color bar
+* `yarg`: ![yarg](images/Yarg.png)
+ - simple white-to-black grayscale color bar (the reverse of `gray`, and almost equivalent to using `-gray` or `gray` with `-r`); this is useful to make contour-like overlays with the `-A` option because its transparency scale (black is transparent) is the opposite of `gray` (white is transparent)
+
+For a long time, I used the following color maps, but nowadays they are somewhat old-fashioned because they aren't "perceptually uniform".  See [this wonderful talk on designing colormaps](https://www.youtube.com/watch?v=xAoljeRJ3lU) for what goes into designing a modern colormap:
+
+* `bluered`: ![bluered](images/Bluered.png)
+ - blue-white-red colorbar, useful for signed data in conjunction with `-Z` option to make white=0
+* `dkbluered`: ![dkbluered](images/Dkbluered.png)
+ - dark blue-white-red colorbar, useful for signed data in conjunction with `-Z` option to make white=0; similar to `bluered` but shows a bit more dynamic range for the maxima/minima by darkening at the ends
+* `hot`: ![hot](images/Hot.png)
+ - black-red-yellow-white color map, useful for nonnegative "intensity" data &mdash; based on [colormap](http://www.mathworks.com/access/helpdesk/help/techdoc/ref/colormap.shtml) of the same name in Matlab, loosely resembling the color of heated object at increasing temperatures
+
+The remaining color scales, mostly based on the corresponding [colormaps(http://www.mathworks.com/access/helpdesk/help/techdoc/ref/colormap.shtml) of the same name in Matlab, are:
+
+* `autumn`: ![autumn](images/Autumn.png)
+ - red-orange-yellow color map
+* `bone`: ![bone](images/Bone.png)
+ - nearly grayscale (blackish to whitish) color map with a tinge of blue
+* `colorcube`: ![colorcube](images/Colorcube.png)
+ - enhanced color-cube color map, basically designed to fill the RGB color space with an emphasis on a few pure colors
+* `cool`: ![cool](images/Cool.png)
+ - cyan-magenta color map
+* `copper`: ![copper](images/Copper.png)
+ - black-copper color map
+* `flag`: ![flag](images/Flag.png)
+ - alternating red/white/blue/black color map
+* `green`: ![green](images/Green.png)
+ - white-green color map; useful for translucent overlays with `-A`
+* `hsv`: ![hsv](images/Hsv.png)
+ - red-yellow-green-cyan-blue-pink-magenta color map formed by changing the hue component in the HSV color space
+* `jet`: ![jet](images/Jet.png)
+ - blue-cyan-yellow-red color map (a variant of `hsv`)
+* `lines`: ![lines](images/Lines_color_map.png)
+ - oscillating color map
+* `pink`: ![pink](images/Pink.png)
+ - pastel black-pink-white color map, used for Sepia tone colorization
+* `prism`: ![prism](images/Prism.png)
+ - repeating red-yellow-green-blue-purple-...-green color map
+* `spring`: ![spring](images/Spring.png)
+ - magenta-yellow color map
+* `summer`: ![summer](images/Summer.png)
+ - green-yellow color map

+* `winter`: ![winter](images/Winter.png)
+ - blue-green color map
+* `yellow`: ![yellow](images/Yellow.png)
+ - white-yellow color map; useful for translucent overlays with `-A`
+
+## Defining your own color scale
+
+You can also make your own color scales.  The are specified in `h5topng` by a simple text file of numbers: each line should contain four whitespace-separated numbers from 0 to 1, each indicating an [RGBA](https://en.wikipedia.org/wiki/RGBA_color_space) value (red,green, blue, and alpha/transparency).  For example, the `bluered` color table is defined by the following text:
+```
+0 0 1   1
+1 1 1   0
+1 0 0   1
+```
+The first line is blue (0,0,1) and opaque (1), the second line is white (1,1,1) and transparent (0), and the third line is red (1,0,0) and opaque (1).  The opacity values are currently only used in `h5topng` for transparent overlays with the `-A` option.
+
+`h5topng` linearly interpolates in the table of RGBA values you provide in order to assign colors for arbitrary intermediate values (where the first line = minimum and the last line = maximum).
+
+Just save your color scale in a text file, and specify the text file pathname to the `-c` option.
+
+## Using the color tables in `h5topng`
+
+To use a given color table in h5topng, simply use the `-c` option.  For example, to use the `hot` color table, you might do:
+```
+h5topng -c hot foobar.h5
+```
+To apply the `bluered` or `dkbluered` tables to signed (positive and negative) data, you usually want to "center" the color table so that the middle (white) corresponds to zero data.  You can do this with the `-Z` option, as in:
+```
+h5topng -Zc bluered foobar.h5
+```
+By default, `h5topng` scales the color table so that the ends correspond to the minimum and maximum of the data.  (In the case of `-Z`, the data is centered so that one end of the color table corresponds to the maximum magnitude.)  However, in some cases you want to "saturate" the color table to emphasize small values, so that all values above some maximum (or below some minimum) are simply assigned to the maximum (or minimum) color in the table.  You can do this using the `-M` (or `-m`) option(s).  For example, to set the minimum at 0 and the maximum at 0.0001, you might do:
+```
+h5topng -m 0 -M 0.0001 -c hot foobar.h5
+```
+Another useful option is `-r`, which reverses the order of the color table (e.g. to make blue positive and red negative).
+
+See [the Unix man page for h5topng](http://ab-initio.mit.edu/h5utils/h5topng-man.html) for more information.
+
+# Making a colorbar image
+
+If you want to use the `h5topng` plot in a publication, often you will want to give a colorbar showing the scale of values. `h5topng` itself does not add axis labels or colorbars, but you can put these together in an external drawing program like [Inkscape](https://en.wikipedia.org/wiki/Inkscape).  To create a PNG image of the color scale, a simple trick is the following:
+```
+echo "0 1" | h5fromtxt colorbar.h5
+h5topng -c hot -X 256 -Y 50 colorbar.h5
+```
+The first command creates an HDF5 file with the numbers 0 and 1 using the [h5fromtxt](http://ab-initio.mit.edu/h5utils/h5totxt-man.html) utility, and the second creates a 256×50 image of the color scale (here for `hot`).  You can, of course, resize the image or change color scales as needed.
+
+(This was already done to create all of the colorbar images in the table above, which you are free to use, redistribute, and modify as desired.)
+
+You will have to manually label the minimum and maximum values when you import the color scale into your drawing program.  If you don't know these values, you can make `h5topng` print them out by passing the `-v` (verbose) option when generating the image from your data.

+# h5topng: generate PNG images from 2d slices of HDF5 files
+
+# Synopsis
+
+    h5topng [OPTION]... [HDF5FILE]...
+
+## Description
+
+`h5topng` is a utility to generate images in PNG (Portable Network Graphics) format from two-dimensional slices of datasets in HDF5 files. It is designed for quick-and-dirty visualization of scientific data, and for batch processing thereof via shell scripts.
+
+HDF5 is a free, portable binary format and supporting library developed by the National Center for Supercomputing Applications at the University of Illinois in Urbana-Champaign. A single `.h5` file can contain multiple data sets; by default, `h5topng` takes the first dataset, but this can be changed via the `-d` option, or by using the syntax `HDF5FILE:DATASET`.
+
+For a three- or four-dimensional dataset you must specify coordinates in one or two slice dimensions, respectively, to get a two-dimensional slice, via the `-xyzt` options. Yet more options control things like the colormap and magnification. Still, the most basic usage is something like `h5topng foo.h5`, which will output a file `foo.png` containing an image from the two-dimensional data in `foo.h5`.
+
+## Options
+
+* `-h` — Display help on the command-line options and usage.
+
+* `-V` — Print the version number and copyright info for `h5topng`.
+
+* `-v` — Verbose output. This output includes the minimum and maximum values encountered in the data, which is useful to know for the `-mM` options.
+
+* `-o file` — Send PNG output to `file` rather than to the filename with .h5 replaced with .png (the default).
+
+* `-x ix`, `-y iy`, `-z iz`, `-t it` — This tells `h5topng` to use a particular slice of a multi-dimensional dataset. e.g. `-x` causes a yz plane (of a 3d dataset) to be used, at an x index of `ix` (where the indices run from zero to one less than the maximum index in that direction). Here, x/y/z correspond to the first/second/third dimensions of the HDF5 dataset. The `-t` option specifies a slice in the last dimension, whichever that might be. See also the `-0` option to shift the origin of the x/y/z slice coordinates to the dataset center.
+ - Instead of specifying a single index as an argument to these options, you can also specify a range of indices in a Matlab-like notation: `start:step:end` or `start:end` (`step` defaults to 1). This loops over that slice index, from `start` to `end` in steps of `step`, producing a sequence of output PNG files (with the slice index appended to the filename, before the `.png`).
+
+* `-0` — Shift the origin of the x/y/z slice coordinates to the dataset center, so that e.g. `-0 -x 0` (or more compactly `-0x0`) returns the central x plane of the dataset instead of the edge x plane. (`-t` coordinates are not affected.)
+
+* `-X scalex`, `-Y scaley`, `-S scale` — Scale the x and y dimensions of the image by `scalex` and `scaley` respectively. The `-S` option scales both x and y. The default is to use scale factors of 1.0; i.e. the image has the same dimensions (in pixels) as the data. Linear interpolation is used to fill in the pixels when the scale factors are not 1.0.
+
+* `-s skewangle` — Skew the image by `skewangle` (in degrees) to the left or right. The result is a parallelogram, with the leftover space in the (square) image filled with either black or white pixels, depending upon the color map.
+
+* `-T` — Transpose the data (interchange the image axes). By default, the first (x) coordinate of the data corresponds to the columns, and the second (y) coordinate corresponds to the rows; transposition reverses this convention.
+
+* `-c colormap` — Use a color map `colormap` rather than the default `gray` color map (a grayscale ramp from white to black). `colormap` is normally the name of one of the color maps provided with `h5topng` (in the `/usr/local/share/h5utils/colormaps` directory), or can instead be the name of a color-map file.
+ - Three useful included color maps are `inferno` (black-red-yellow, useful for intensity data), `RdBu` (red-white-blue, useful for signed data), and `viridis` (a blue-green-yellow color map), all of which are [adapted from Matplotlib](https://matplotlib.org/users/colormaps.html). If you use the `RdBu` color map for signed data, you may also want to use the `-Z` option so that the center of the color scale (white) corresponds to zero.
+ - See [color tables in h5topng](h5topng-colors.md) for more information.
+
+* `-r` — Reverse the ordering of the color map. You can also accomplish this by putting a `-` before the colormap name in the `-c` or `-a` option, e.g. `-c -RdBu`.
+
+* `-Z` — Center the color scale on the value zero in the data.
+
+* `-m min`, `-M max` — Normally, the bottom and top of the color map correspond to the minimum and maximum values in the data. Using these options, you can make the bottom and top of the color map correspond to `min` and `max` instead. Data values below or above this range will be treated as if they were `min` or `max` respectively. See also the `-Z` and `-R` options.
+
+* `-R` — When multiple files are specified, set the bottom and top of the color maps according to the minimum and maximum over all the data. This is useful to process many files using a consistent color scale, since otherwise the scale is set for each file individually.
+
+* `-C file`, `-b val` — Superimpose contour outlines from the first dataset in the `file` HDF5 file on all of the output images. (If the contour dataset does not have the same dimensions as the output data, it is periodically "tiled" over the output.) You can use the syntax `file:dataset` to specify a particular dataset within the file. The contour outlines are around a value of `val` (defaults to middle of value range in `file`).
+
+* `-A file`, `-a colormap`:`opacity` — Translucently overlay the data from the first dataset in the `file` HDF5 file, which should have the same dimensions as the input dataset, on all of the output images, using the colormap `colormap` with opacity (from 0 for completely transparent to 1 for completely opaque) `opacity` multiplied by the opacity (alpha) values in the colormap. (If the overlay dataset does not have the same dimensions as the output data, it is periodically "tiled" over the output.) You can use the syntax `file:dataset` to specify a particular dataset within the file.
+
+- Some predefined colormaps that work particularly well for this feature are `yellow` (transparent white to opaque yellow) `gray` (transparent white to opaque black), `yarg` (transparent black to opaque white), `green` (transparent white to opaque green), and `bluered` (opaque blue to transparent white to opaque red). You can prepend `-` to the colormap name to reverse the colormap order. (See also `-c`, above.) The default for `-a` is `yellow:0.3` (yellow colormap multiplied by 30% opacity).
+
+* `-d name` — Use dataset `name` from the input files; otherwise, the first dataset from each file is used. Alternatively, use the syntax `HDF5FILE:DATASET`, which allows you to specify a different dataset for each file. You can use the `h5ls` command (included with hdf5) to find the names of datasets within a file.
+
+* `-8` — Use 8-bit (indexed) color for the PNG output, instead of 24-bit (direct) color (the default). (This shrinks the image size slightly, with some degradation in quality.) Not supported in conjunction with the `-A` (translucent overlay) option.

+# h5totxt: generate comma-delimited text from 2d slices of HDF5 files
+
+## Synopsis
+
+    h5totxt [OPTION]... [HDF5FILE]...
+
+## Description
+
+`h5totxt` is a utility to generate comma-delimited text (and similar formats) from one-, two-, or more-dimensional slices of numeric datasets in HDF5 files. This way, the data can easily be imported into spreadsheets and similar programs for analysis and visualization.
+
+HDF5 is a free, portable binary format and supporting library developed by the National Center for Supercomputing Applications at the University of Illinois in Urbana-Champaign. A single `.h5` file can contain multiple data sets; by default, `h5totxt` takes the first dataset, but this can be changed via the `-d` option, or by using the syntax `HDF5FILE:DATASET`.
+
+By default, the entire dataset is dumped to the output. in row-major order. For 3d datasets, this corresponds to a sequence of yz slices, in order of increasing x, separated by blank lines. If `-T` is specified, outputs in the transposed (column-major) order instead
+
+Often, however, you want only a one- or two-dimensional slice of multi-dimensional data. To do this, you specify coordinates in one or more slice dimensions, via the `-xyzt` options.
+
+The most basic usage is something like `h5totxt foo.h5`, which will output comma-delimited text to stdout from the data in `foo.h5`.
+
+## Options
+
+* `-h` — Display help on the command-line options and usage.
+
+* `-V` — Print the version number and copyright info for `h5totxt`.
+
+* `-v` — Verbose output.
+
+* `-o file` — Send text output to `file` rather than to stdout (the default).
+
+* `-s sep` — Use the string `sep` to separate columns of the output rather than a comma (the default).
+
+* `-x ix`, `-y iy`, `-z iz`, `-t it` — This tells `h5totxt` to use a particular slice of a multi-dimensional dataset. e.g. `-x` causes a yz plane (of a 3d dataset) to be used, at an x index of `ix` (where the indices run from zero to one less than the maximum index in that direction). Here, x/y/z correspond to the first/second/third dimensions of the HDF5 dataset. The `-t` option specifies a slice in the last dimension, whichever that might be. See also the `-0` option to shift the origin of the x/y/z slice coordinates to the dataset center.
+
+* `-0` — Shift the origin of the x/y/z slice coordinates to the dataset center, so that e.g. -0 -x 0 (or more compactly -0x0) returns the central x plane of the dataset instead of the edge x plane. (`-t` coordinates are not affected.)
+
+* `-T` — Transpose the data (interchange the dimension ordering). By default, no transposition is done.
+
+* `-. numdigits` — Output `numdigits` digits after the decimal point (defaults to 16).
+
+* `-d name` — Use dataset `name` from the input files; otherwise, the first dataset from each file is used. Alternatively, use the syntax `HDF5FILE:DATASET`, which allows you to specify a different dataset for each file. You can use the `h5ls` command (included with hdf5) to find the names of datasets within a file.

+# h5tov5d: convert datasets in HDF5 files to Vis5d format
+
+## Synopsis
+
+    h5tov5d [OPTION]... [HDF5FILE]...
+
+## Description
+
+`h5tov5d` is a program to generate Vis5d data files from multidimensional datasets in HDF5 files. Vis5d is a free volumetric visualization program capable of displaying 3, 4, or even 5 dimensional datasets (using time for the 4th dimension and different variables for the 5th dimension).
+
+HDF5 is a free, portable binary format and supporting library developed by the National Center for Supercomputing Applications at the University of Illinois in Urbana-Champaign. A single `h5` file can contain multiple data sets; by default, `h5tov5d` takes the first dataset, but this can be changed via the `-d` option, or by using the syntax `HDF5FILE:DATASET`.
+
+1d/2d/3d datasets are converted into 3d Vis5d datasets. 4d datasets are converted into a time series of 3d datasets, with the first dimension marking the time. 5d datasets are converted into several variables of time series of 3d datasets, with the first dimension as the variable index and the second dimension as the time. Often, however, you want only a three-dimensional "slice" of four (or more) dimensional data. To do this, you specify coordinates in one (or more) slice dimension(s), via the `-xyzt` options.
+
+A typical invocation is of the form `h5tov5d foo.h5`, which will output a Vis5d data file `foo.v5d` from the data in `foo.h5`.
+
+## Options
+
+* `-h` — Display help on the command-line options and usage.
+
+* `-V` — Print the version number and copyright info for `h5tov5d`.
+
+* `-v` — Verbose output.
+
+* `-T` — Transpose the output dimensions (reverse their order).
+
+* `-o` `file` — Save the datasets from all of the input files to a single Vis5d `file` with each dataset being expressed as a separate Vis5d variable. In this way, you can use Vis5d to superimpose and compare the plots from the different datasets. The first two dimensions (or three, for 4d datasets) must be the same for all of the input datasets.
+
+ - Otherwise, the default behavior is to save each dataset to a separate Vis5d file, with the `.h5` suffix of the input filename replaced by `.v5d` in the output filename.
+
+* `-1`, `-2`, `-4` — Use 1 (the default), 2, or 4 bytes to store each data point in the output file. Fewer bytes will cause Vis5d to be faster (as well as requiring less storage and memory), but will decrease the resolution in the values. `-1` will break up the data values into one of 256 possible values (on a linear scale from the minimum to the maximum value in your data), `-2` will allow 65536 possible values, and `-4` will use 4-byte floating-point numbers for an "exact" representation. In most circumstances, `-1` is more than adequate for data visualization purposes.
+
+* `-x` `ix`, `-y` `iy`, `-z` `iz`, `-t` `it` — This tells `h5tov5d` to use a particular slice of a multi-dimensional dataset. e.g. `-x` uses the subset (with one less dimension) at an x index of `ix` (where the indices run from zero to one less than the maximum index in that direction). Here, x/y/z correspond to the first/second/third dimensions of the HDF5 dataset. The `-t` option specifies a slice in the last dimension, whichever that might be. See also the `-0` option to shift the origin of the x/y/z slice coordinates to the dataset center.
+
+* `-0` — Shift the origin of the x/y/z slice coordinates to the dataset center, so that e.g. -0 -x 0 (or more compactly -0x0) returns the central x plane of the dataset instead of the edge x plane. (`-t` coordinates are not affected.)

+# h5tovtk: convert datasets in HDF5 files to VTK format
+
+# Synopsis
+
+    h5tovtk [OPTION]... [HDF5FILE]...
+
+## Description
+
+`h5tovtk` is a program to generate VTK data files from multidimensional datasets in HDF5 files. VTK, the Visualization ToolKit, is an open-source, freely available software system for 3D computer graphics, image processing, and visualization. VTK itself is a programming library, but it is also the basis for a number of end-user graphical visualization programs.
+
+HDF5 is a free, portable binary format and supporting library developed by the National Center for Supercomputing Applications at the University of Illinois in Urbana-Champaign. A single `h5` file can contain multiple datasets; by default, `h5tovtk` takes the first dataset, but this can be changed via the `-d` option, or by using the syntax `HDF5FILE:DATASET`.
+
+1d/2d/3d datasets are converted into 3d VTK datasets. Normally, a single scalar VTK dataset is output, but vectors and fields can be output via the `-o` option below.
+
+A typical invocation is of the form `h5tovtk foo.h5`, which will output a VTK data file `foo.vtk` from the data in `foo.h5`.
+
+## Options
+
+* `-h` — Display help on the command-line options and usage.
+
+* `-V` — Print the version number and copyright info for `h5tovtk`.
+
+* `-v` — Verbose output.
+
+* `-o file` — Save all the input datasets to a single VTK `file`. If there is only one dataset, it is output to a VTK scalar dataset; if there are three datasets, they are output as a VTK vector dataset; all other numbers of datasets are combined into a VTK field dataset.
+
+ - Otherwise, the default behavior is to save each dataset to a separate VTK file, with the `.h5` suffix of the input filename replaced by `.vtk` in the output filename.
+
+ - Only three-dimensional datasets may be written to the VTK file. If you have a four (or more) dimensional data set, then you must take a three-dimensional "slice" of the multi-dimensional data. To do this, you specify coordinates in one (or more) slice dimension(s), via the `-xyzt` options.
+
+* `-1`, `-2`, `-4` — Use 1 , 2, or 4 bytes to store each data point in the output file. Fewer bytes require less storage and memory, but will decrease the resolution in the values. `-1` will break up the data values into one of 256 possible values (on a linear scale from the minimum to the maximum value in your data), `-2` will allow 65536 possible values, and `-4` (the default) will use 4-byte floating-point numbers for an "exact" representation.
+
+* `-a` — Output in ASCII format; otherwise, VTK’s more compact, but less readable and somewhat less portable binary format is used.
+
+* `-n` — For binary output (see `-a` above), by default the data is written in bigendian byte order, which is normally the order that VTK expects. However, some external tools and a few VTK classes use the native byte ordering instead (which may not be bigendian), and the `-n` option causes `h5tovtk` to output binary data in the native ordering.
+
+* `-m min`, `-M max` — When `-1` or `-2` are used, the input data are converted to a linear integer scale. Normally, the bottom and top of this scale correspond to the minimum and maximum values in the data. Using the `-m` and `-M` options, you can make the bottom and top of the scale correspond to `min` and `max` instead, respectively. Data values below or above this range will be treated as if they were `min` or `max` respectively. See also the `-Z` option.
+
+* `-Z` — For `-1` or `-2` output, center the linear integer scale on the value zero in the data.
+
+* `-r` — Invert the output values (map the minimum to the maximum and vice versa).
+
+* `-x ix`, `-y iy`, `-z iz`, `-t it` — This tells `h5tovtk` to use a particular slice of a multi-dimensional dataset. e.g. `-x` uses the subset (with one less dimension) at an x index of `ix` (where the indices run from zero to one less than the maximum index in that direction). Here, x/y/z correspond to the first/second/third dimensions of the HDF5 dataset. The `-t` option specifies a slice in the last dimension, whichever that might be. See also the `-0` option to shift the origin of the x/y/z slice coordinates to the dataset center.
+
+* `-0` — Shift the origin of the x/y/z slice coordinates to the dataset center, so that e.g. -0 -x 0 (or more compactly -0x0) returns the central x plane of the dataset instead of the edge x plane. (`-t` coordinates are not affected.)
+
+* `-d name` — Use dataset `name` from the input files; otherwise, the first dataset from each file is used. Alternatively, use the syntax `HDF5FILE:DATASET`, which allows you to specify a different dataset for each file. You can use the `h5ls` command (included with hdf5) to find the names of datasets within a file.

+.SH NAME
+h4fromh5 \- convert HDF5 scientific dataset to an HDF4 file
+.SH SYNOPSIS
+.B h4fromh5
+[\fIOPTION\fR]... [\fIHDF4FILE\fR]...
+.SH DESCRIPTION
+.PP
+." Add any additional description here
+h4fromh5 takes one or more files in HDF5 format and outputs files in
+HDF4 format containing the datasets from the HDF5 files.  (Currently,
+only a single dataset per HDF5 file is converted.)
+
+HDF4 and HDF5 are free, portable binary formats and supporting libraries
+developed by the National Center for Supercomputing Applications at
+the University of Illinois in Urbana-Champaign.
+
+ A single
+.I h5
+file can contain multiple data sets; by default,
+.I h4fromh5
+converts the first dataset, but this can be changed via the
+.B -d
+option, or by using the syntax \fIHDF5FILE:DATASET\fR.
+
+The most basic usage is something like \'h4fromh5 foo.h5\', which
+will output a file foo.hdf containing the scientific dataset from
+foo.h5.
+.SH OPTIONS
+.TP
+.B -h
+Display help on the command-line options and usage.
+.TP
+.B -V
+Print the version number and copyright info for h4fromh5.
+.TP
+.B -v
+Verbose output.
+.TP
+.B -T
+Transpose the output dataset (e.g. LxMxN becomes NxMxL).  This is often
+useful because HDF5 programs typically follow C (row-major) conventions
+while HDF4 programs often follow Fortran (column-major, transposed)
+conventions for array ordering.
+.TP
+\fB\-o\fR \fIfile\fR
+Send HDF output to
+.I file
+rather than to the input filename with .h5 replaced with .hdf (the
+default).
+.TP
+\fB\-d\fR \fIname\fR
+Read from dataset
+.I name
+in the input; otherwise, the first dataset in the input file is used.
+Alternatively, use the syntax \fIHDF5FILE:DATASET\fR when the
+input file names are specified.
+.SH BUGS
+Send bug reports to S. G. Johnson, stevenj@alum.mit.edu.
