5 Everyone is permitted to copy and distribute verbatim copies
6 of this license document, but changing it is not allowed.
7
8 Preamble
9
10 The licenses for most software are designed to take away your
11 freedom to share and change it. By contrast, the GNU General Public
12 License is intended to guarantee your freedom to share and change free
13 software--to make sure the software is free for all its users. This
14 General Public License applies to most of the Free Software
15 Foundation's software and to any other program whose authors commit to
16 using it. (Some other Free Software Foundation software is covered by
17 the GNU Library General Public License instead.) You can apply it to
18 your programs, too.
19
20 When we speak of free software, we are referring to freedom, not
21 price. Our General Public Licenses are designed to make sure that you
22 have the freedom to distribute copies of free software (and charge for
23 this service if you wish), that you receive source code or can get it
24 if you want it, that you can change the software or use pieces of it
25 in new free programs; and that you know you can do these things.
26
27 To protect your rights, we need to make restrictions that forbid
28 anyone to deny you these rights or to ask you to surrender the rights.
29 These restrictions translate to certain responsibilities for you if you
30 distribute copies of the software, or if you modify it.
31
32 For example, if you distribute copies of such a program, whether
33 gratis or for a fee, you must give the recipients all the rights that
34 you have. You must make sure that they, too, receive or can get the
35 source code. And you must show them these terms so they know their
36 rights.
37
38 We protect your rights with two steps: (1) copyright the software, and
39 (2) offer you this license which gives you legal permission to copy,
40 distribute and/or modify the software.
41
42 Also, for each author's protection and ours, we want to make certain
43 that everyone understands that there is no warranty for this free
44 software. If the software is modified by someone else and passed on, we
45 want its recipients to know that what they have is not the original, so
46 that any problems introduced by others will not reflect on the original
47 authors' reputations.
48
49 Finally, any free program is threatened constantly by software
50 patents. We wish to avoid the danger that redistributors of a free
51 program will individually obtain patent licenses, in effect making the
52 program proprietary. To prevent this, we have made it clear that any
53 patent must be licensed for everyone's free use or not licensed at all.
54
55 The precise terms and conditions for copying, distribution and
56 modification follow.
57
58 GNU GENERAL PUBLIC LICENSE
59 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
60
61 0. This License applies to any program or other work which contains
62 a notice placed by the copyright holder saying it may be distributed
63 under the terms of this General Public License. The "Program", below,
64 refers to any such program or work, and a "work based on the Program"
65 means either the Program or any derivative work under copyright law:
66 that is to say, a work containing the Program or a portion of it,
67 either verbatim or with modifications and/or translated into another
68 language. (Hereinafter, translation is included without limitation in
69 the term "modification".) Each licensee is addressed as "you".
70
71 Activities other than copying, distribution and modification are not
72 covered by this License; they are outside its scope. The act of
73 running the Program is not restricted, and the output from the Program
74 is covered only if its contents constitute a work based on the
75 Program (independent of having been made by running the Program).
76 Whether that is true depends on what the Program does.
77
78 1. You may copy and distribute verbatim copies of the Program's
79 source code as you receive it, in any medium, provided that you
80 conspicuously and appropriately publish on each copy an appropriate
81 copyright notice and disclaimer of warranty; keep intact all the
82 notices that refer to this License and to the absence of any warranty;
83 and give any other recipients of the Program a copy of this License
84 along with the Program.
85
86 You may charge a fee for the physical act of transferring a copy, and
87 you may at your option offer warranty protection in exchange for a fee.
88
89 2. You may modify your copy or copies of the Program or any portion
90 of it, thus forming a work based on the Program, and copy and
91 distribute such modifications or work under the terms of Section 1
92 above, provided that you also meet all of these conditions:
93
94 a) You must cause the modified files to carry prominent notices
95 stating that you changed the files and the date of any change.
96
97 b) You must cause any work that you distribute or publish, that in
98 whole or in part contains or is derived from the Program or any
99 part thereof, to be licensed as a whole at no charge to all third
100 parties under the terms of this License.
101
102 c) If the modified program normally reads commands interactively
103 when run, you must cause it, when started running for such
104 interactive use in the most ordinary way, to print or display an
105 announcement including an appropriate copyright notice and a
106 notice that there is no warranty (or else, saying that you provide
107 a warranty) and that users may redistribute the program under
108 these conditions, and telling the user how to view a copy of this
109 License. (Exception: if the Program itself is interactive but
110 does not normally print such an announcement, your work based on
111 the Program is not required to print an announcement.)
112
113 These requirements apply to the modified work as a whole. If
114 identifiable sections of that work are not derived from the Program,
115 and can be reasonably considered independent and separate works in
116 themselves, then this License, and its terms, do not apply to those
117 sections when you distribute them as separate works. But when you
118 distribute the same sections as part of a whole which is a work based
119 on the Program, the distribution of the whole must be on the terms of
120 this License, whose permissions for other licensees extend to the
121 entire whole, and thus to each and every part regardless of who wrote it.
122
123 Thus, it is not the intent of this section to claim rights or contest
124 your rights to work written entirely by you; rather, the intent is to
125 exercise the right to control the distribution of derivative or
126 collective works based on the Program.
127
128 In addition, mere aggregation of another work not based on the Program
129 with the Program (or with a work based on the Program) on a volume of
130 a storage or distribution medium does not bring the other work under
131 the scope of this License.
132
133 3. You may copy and distribute the Program (or a work based on it,
134 under Section 2) in object code or executable form under the terms of
135 Sections 1 and 2 above provided that you also do one of the following:
136
137 a) Accompany it with the complete corresponding machine-readable
138 source code, which must be distributed under the terms of Sections
139 1 and 2 above on a medium customarily used for software interchange; or,
140
141 b) Accompany it with a written offer, valid for at least three
142 years, to give any third party, for a charge no more than your
143 cost of physically performing source distribution, a complete
144 machine-readable copy of the corresponding source code, to be
145 distributed under the terms of Sections 1 and 2 above on a medium
146 customarily used for software interchange; or,
147
148 c) Accompany it with the information you received as to the offer
149 to distribute corresponding source code. (This alternative is
150 allowed only for noncommercial distribution and only if you
151 received the program in object code or executable form with such
152 an offer, in accord with Subsection b above.)
153
154 The source code for a work means the preferred form of the work for
155 making modifications to it. For an executable work, complete source
156 code means all the source code for all modules it contains, plus any
157 associated interface definition files, plus the scripts used to
158 control compilation and installation of the executable. However, as a
159 special exception, the source code distributed need not include
160 anything that is normally distributed (in either source or binary
161 form) with the major components (compiler, kernel, and so on) of the
162 operating system on which the executable runs, unless that component
163 itself accompanies the executable.
164
165 If distribution of executable or object code is made by offering
166 access to copy from a designated place, then offering equivalent
167 access to copy the source code from the same place counts as
168 distribution of the source code, even though third parties are not
169 compelled to copy the source along with the object code.
170
171 4. You may not copy, modify, sublicense, or distribute the Program
172 except as expressly provided under this License. Any attempt
173 otherwise to copy, modify, sublicense or distribute the Program is
174 void, and will automatically terminate your rights under this License.
175 However, parties who have received copies, or rights, from you under
176 this License will not have their licenses terminated so long as such
177 parties remain in full compliance.
178
179 5. You are not required to accept this License, since you have not
180 signed it. However, nothing else grants you permission to modify or
181 distribute the Program or its derivative works. These actions are
182 prohibited by law if you do not accept this License. Therefore, by
183 modifying or distributing the Program (or any work based on the
184 Program), you indicate your acceptance of this License to do so, and
185 all its terms and conditions for copying, distributing or modifying
186 the Program or works based on it.
187
188 6. Each time you redistribute the Program (or any work based on the
189 Program), the recipient automatically receives a license from the
190 original licensor to copy, distribute or modify the Program subject to
191 these terms and conditions. You may not impose any further
192 restrictions on the recipients' exercise of the rights granted herein.
193 You are not responsible for enforcing compliance by third parties to
194 this License.
195
196 7. If, as a consequence of a court judgment or allegation of patent
197 infringement or for any other reason (not limited to patent issues),
198 conditions are imposed on you (whether by court order, agreement or
199 otherwise) that contradict the conditions of this License, they do not
200 excuse you from the conditions of this License. If you cannot
201 distribute so as to satisfy simultaneously your obligations under this
202 License and any other pertinent obligations, then as a consequence you
203 may not distribute the Program at all. For example, if a patent
204 license would not permit royalty-free redistribution of the Program by
205 all those who receive copies directly or indirectly through you, then
206 the only way you could satisfy both it and this License would be to
207 refrain entirely from distribution of the Program.
208
209 If any portion of this section is held invalid or unenforceable under
210 any particular circumstance, the balance of the section is intended to
211 apply and the section as a whole is intended to apply in other
212 circumstances.
213
214 It is not the purpose of this section to induce you to infringe any
215 patents or other property right claims or to contest validity of any
216 such claims; this section has the sole purpose of protecting the
217 integrity of the free software distribution system, which is
218 implemented by public license practices. Many people have made
219 generous contributions to the wide range of software distributed
220 through that system in reliance on consistent application of that
221 system; it is up to the author/donor to decide if he or she is willing
222 to distribute software through any other system and a licensee cannot
223 impose that choice.
224
225 This section is intended to make thoroughly clear what is believed to
226 be a consequence of the rest of this License.
227
228 8. If the distribution and/or use of the Program is restricted in
229 certain countries either by patents or by copyrighted interfaces, the
230 original copyright holder who places the Program under this License
231 may add an explicit geographical distribution limitation excluding
232 those countries, so that distribution is permitted only in or among
233 countries not thus excluded. In such case, this License incorporates
234 the limitation as if written in the body of this License.
235
236 9. The Free Software Foundation may publish revised and/or new versions
237 of the General Public License from time to time. Such new versions will
238 be similar in spirit to the present version, but may differ in detail to
239 address new problems or concerns.
240
241 Each version is given a distinguishing version number. If the Program
242 specifies a version number of this License which applies to it and "any
243 later version", you have the option of following the terms and conditions
244 either of that version or of any later version published by the Free
245 Software Foundation. If the Program does not specify a version number of
246 this License, you may choose any version ever published by the Free Software
247 Foundation.
248
249 10. If you wish to incorporate parts of the Program into other free
250 programs whose distribution conditions are different, write to the author
251 to ask for permission. For software which is copyrighted by the Free
252 Software Foundation, write to the Free Software Foundation; we sometimes
253 make exceptions for this. Our decision will be guided by the two goals
254 of preserving the free status of all derivatives of our free software and
255 of promoting the sharing and reuse of software generally.
256
257 NO WARRANTY
258
259 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
260 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
261 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
262 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
263 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
264 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
265 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
266 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
267 REPAIR OR CORRECTION.
268
269 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
270 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
271 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
272 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
273 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
274 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
275 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
276 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
277 POSSIBILITY OF SUCH DAMAGES.
278
279 END OF TERMS AND CONDITIONS
280
281 How to Apply These Terms to Your New Programs
282
283 If you develop a new program, and you want it to be of the greatest
284 possible use to the public, the best way to achieve this is to make it
285 free software which everyone can redistribute and change under these terms.
286
287 To do so, attach the following notices to the program. It is safest
288 to attach them to the start of each source file to most effectively
289 convey the exclusion of warranty; and each file should have at least
290 the "copyright" line and a pointer to where the full notice is found.
291
292 <one line to give the program's name and a brief idea of what it does.>
293 Copyright (C) 19yy <name of author>
294
295 This program is free software; you can redistribute it and/or modify
296 it under the terms of the GNU General Public License as published by
297 the Free Software Foundation; either version 2 of the License, or
298 (at your option) any later version.
299
300 This program is distributed in the hope that it will be useful,
301 but WITHOUT ANY WARRANTY; without even the implied warranty of
302 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
303 GNU General Public License for more details.
304
305 You should have received a copy of the GNU General Public License
306 along with this program; if not, write to the Free Software
307 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
308
309
310 Also add information on how to contact you by electronic and paper mail.
311
312 If the program is interactive, make it output a short notice like this
313 when it starts in an interactive mode:
314
315 Gnomovision version 69, Copyright (C) 19yy name of author
316 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
317 This is free software, and you are welcome to redistribute it
318 under certain conditions; type `show c' for details.
319
320 The hypothetical commands `show w' and `show c' should show the appropriate
321 parts of the General Public License. Of course, the commands you use may
322 be called something other than `show w' and `show c'; they could even be
323 mouse-clicks or menu items--whatever suits your program.
324
325 You should also get your employer (if you work as a programmer) or your
326 school, if any, to sign a "copyright disclaimer" for the program, if
327 necessary. Here is a sample; alter the names:
328
329 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
330 `Gnomovision' (which makes passes at compilers) written by James Hacker.
331
332 <signature of Ty Coon>, 1 April 1989
333 Ty Coon, President of Vice
334
335 This General Public License does not permit incorporating your program into
336 proprietary programs. If your program is a subroutine library, you may
337 consider it more useful to permit linking proprietary applications with the
338 library. If this is what you want to do, use the GNU Library General
339 Public License instead of this License.

2 UnRTF is a moderately complicated converter from RTF to other
3 formats, including HTML, LaTeX, text, and PostScript. Converting
4 to HTML, it supports tables, fonts, colors, embedded images,
5 hyperlinks, paragraph alignment among other things. All other
6 conversions are "alpha"--just begun.
7
8 Compiling with GCC: type "make all", and assuming you have GCC
9 and GNU make, it should compile without any warnings or errors
10 under Linux, BSD, and DOS (using DJGPP). Amiga/GCC users
11 should utilize the build.amiga file. Please let me know of
12 any compilation problems.
13
14 This program includes no warranty whatsoever. It is provided
15 "AS IS". For more information please read the COPYING
16 document, which should be included with the source code.
17 It describes the GNU Public License, which covers UnRTF.
18
19 Enjoy.

1 UnRTF by Zach Smith
2
3 A few tasks that need doing as of 18 Sept 01
4 --------------------------------------------
5
6 * Make sure --inline still works; limit it to HTML.
7
8 * Add a module for an intermediate character set for charset
9 conversions.
10
11 * Finish output personalities for LaTeX, PostScript, text, vt, WPML.
12 - Postscript word-level metrics and printing.
13 - Postscript paragraph alignment.
14 - Postscript tables.
15 - Postscript more font faces.
16 - Does LaTeX support emboss, engrave, outline, shadow?
17
18 * Point-lists -- rather important.
19
20 * Index entries.
21
22 * TOC entries.
23
24 * Headers.
25
26 * Footers.
27
28 * Add support for line-based images (the RTF "shape" concept),
29 converting to Beest format or another?
30
31 * Centering not working within tables?
32
33 * HTML: javascript-based shadow/outline/emboss/engrave ?
34
35 * Style sheet support?
36
37 * HTML: Multiple columns kludge using tables or layers?
38
39 * Need to support more Mac RTF special expressions.
