1
The  FreeType 2  font  engine is  copyrighted  work and  cannot be  used
2
legally  without a  software license.   In  order to  make this  project
3
usable  to a vast  majority of  developers, we  distribute it  under two
4
mutually exclusive open-source licenses.
5

    
6
This means  that *you* must choose  *one* of the  two licenses described
7
below, then obey  all its terms and conditions when  using FreeType 2 in
8
any of your projects or products.
9

    
10
  - The FreeType License, appended below, which is similar
11
    to the original BSD license *with* an advertising clause that forces
12
    you  to  explicitly cite  the  FreeType  project  in your  product's
13
    documentation.  All  details are in the license  file.  This license
14
    is  suited  to products  which  don't  use  the GNU  General  Public
15
    License.
16

    
17
  - The GNU  General Public License  version 2, also appended below (any
18
    later version can be used  also), for programs which already use the
19
    GPL.  Note  that the  FTL is  incompatible with the  GPL due  to its
20
    advertisement clause.
21

    
22
The contributed PCF driver comes with a license similar to that of the X
23
Window System.   It is  compatible to the  above two licenses  (see file
24
src/pcf/readme).

Introduction
39
============
40

    
41
  The FreeType  Project is distributed in  several archive packages;
42
  some of them may contain, in addition to the FreeType font engine,
43
  various tools and  contributions which rely on, or  relate to, the
44
  FreeType Project.
45

    
46
  This  license applies  to all  files found  in such  packages, and
47
  which do not  fall under their own explicit  license.  The license
48
  affects  thus  the  FreeType   font  engine,  the  test  programs,
49
  documentation and makefiles, at the very least.
50

    
51
  This  license   was  inspired  by  the  BSD,   Artistic,  and  IJG
52
  (Independent JPEG  Group) licenses, which  all encourage inclusion
53
  and  use of  free  software in  commercial  and freeware  products
54
  alike.  As a consequence, its main points are that:
55

    
56
    o We don't promise that this software works. However, we will be
57
      interested in any kind of bug reports. (`as is' distribution)
58

    
59
    o You can  use this software for whatever you  want, in parts or
60
      full form, without having to pay us. (`royalty-free' usage)
61

    
62
    o You may not pretend that  you wrote this software.  If you use
63
      it, or  only parts of it,  in a program,  you must acknowledge
64
      somewhere  in  your  documentation  that  you  have  used  the
65
      FreeType code. (`credits')
66

    
67
  We  specifically  permit  and  encourage  the  inclusion  of  this
68
  software, with  or without modifications,  in commercial products.
69
  We  disclaim  all warranties  covering  The  FreeType Project  and
70
  assume no liability related to The FreeType Project.
71

    
72

    
73
  Finally,  many  people  asked  us  for  a  preferred  form  for  a
74
  credit/disclaimer to use in compliance with this license.  We thus
75
  encourage you to use the following text:
76

   """

Legal Terms
84
===========
85

    
86
0. Definitions
87
--------------
88

    
89
  Throughout this license,  the terms `package', `FreeType Project',
90
  and  `FreeType  archive' refer  to  the  set  of files  originally
91
  distributed  by the  authors  (David Turner,  Robert Wilhelm,  and
92
  Werner Lemberg) as the `FreeType Project', be they named as alpha,
93
  beta or final release.
94

    
95
  `You' refers to  the licensee, or person using  the project, where
96
  `using' is a generic term including compiling the project's source
97
  code as  well as linking it  to form a  `program' or `executable'.
98
  This  program is  referred to  as  `a program  using the  FreeType
99
  engine'.
100

    
101
  This  license applies  to all  files distributed  in  the original
102
  FreeType  Project,   including  all  source   code,  binaries  and
103
  documentation,  unless  otherwise  stated   in  the  file  in  its
104
  original, unmodified form as  distributed in the original archive.
105
  If you are  unsure whether or not a particular  file is covered by
106
  this license, you must contact us to verify this.
107

    
108
  The FreeType  Project is copyright (C) 1996-2000  by David Turner,
109
  Robert Wilhelm, and Werner Lemberg.  All rights reserved except as
110
  specified below.
111

    
112
1. No Warranty
113
--------------
114

    
115
  THE FREETYPE PROJECT  IS PROVIDED `AS IS' WITHOUT  WARRANTY OF ANY
116
  KIND, EITHER  EXPRESS OR IMPLIED,  INCLUDING, BUT NOT  LIMITED TO,
117
  WARRANTIES  OF  MERCHANTABILITY   AND  FITNESS  FOR  A  PARTICULAR
118
  PURPOSE.  IN NO EVENT WILL ANY OF THE AUTHORS OR COPYRIGHT HOLDERS
119
  BE LIABLE  FOR ANY DAMAGES CAUSED  BY THE USE OR  THE INABILITY TO
120
  USE, OF THE FREETYPE PROJECT.
121

    
122
2. Redistribution
123
-----------------
124

    
125
  This  license  grants  a  worldwide, royalty-free,  perpetual  and
126
  irrevocable right  and license to use,  execute, perform, compile,
127
  display,  copy,   create  derivative  works   of,  distribute  and
128
  sublicense the  FreeType Project (in  both source and  object code
129
  forms)  and  derivative works  thereof  for  any  purpose; and  to
130
  authorize others  to exercise  some or all  of the  rights granted
131
  herein, subject to the following conditions:
132

    
133
    o Redistribution of  source code  must retain this  license file
134
      (`FTL.TXT') unaltered; any  additions, deletions or changes to
135
      the original  files must be clearly  indicated in accompanying
136
      documentation.   The  copyright   notices  of  the  unaltered,
137
      original  files must  be  preserved in  all  copies of  source
138
      files.
139

    
140
    o Redistribution in binary form must provide a  disclaimer  that
141
      states  that  the software is based in part of the work of the
142
      FreeType Team,  in  the  distribution  documentation.  We also
143
      encourage you to put an URL to the FreeType web page  in  your
144
      documentation, though this isn't mandatory.
145

    
146
  These conditions  apply to any  software derived from or  based on
147
  the FreeType Project,  not just the unmodified files.   If you use
148
  our work, you  must acknowledge us.  However, no  fee need be paid
149
  to us.
150

    
151
3. Advertising
152
--------------
153

    
154
  Neither the  FreeType authors and  contributors nor you  shall use
155
  the name of the  other for commercial, advertising, or promotional
156
  purposes without specific prior written permission.
157

    
158
  We suggest,  but do not require, that  you use one or  more of the
159
  following phrases to refer  to this software in your documentation
160
  or advertising  materials: `FreeType Project',  `FreeType Engine',
161
  `FreeType library', or `FreeType Distribution'.
162

    
163
  As  you have  not signed  this license,  you are  not  required to
164
  accept  it.   However,  as  the FreeType  Project  is  copyrighted
165
  material, only  this license, or  another one contracted  with the
166
  authors, grants you  the right to use, distribute,  and modify it.
167
  Therefore,  by  using,  distributing,  or modifying  the  FreeType
168
  Project, you indicate that you understand and accept all the terms
169
  of this license.
170

    
171
4. Contacts

		    GNU GENERAL PUBLIC LICENSE
203
		       Version 2, June 1991
204

    
205
 Copyright (C) 1989, 1990, 1991, 1992 Free Software Foundation, Inc.
206
 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
207
 Everyone is permitted to copy and distribute verbatim copies
208
 of this license document, but changing it is not allowed.
209

    
210
			    Preamble
211

    
212
  The licenses for most software are designed to take away your
213
freedom to share and change it.  By contrast, the GNU General Public
214
License is intended to guarantee your freedom to share and change free
215
software--to make sure the software is free for all its users.  This
216
General Public License applies to most of the Free Software
217
Foundation's software and to any other program whose authors commit to
218
using it.  (Some other Free Software Foundation software is covered by
219
the GNU Library General Public License instead.)  You can apply it to
220
your programs, too.
221

    
222
  When we speak of free software, we are referring to freedom, not
223
price.  Our General Public Licenses are designed to make sure that you
224
have the freedom to distribute copies of free software (and charge for
225
this service if you wish), that you receive source code or can get it
226
if you want it, that you can change the software or use pieces of it
227
in new free programs; and that you know you can do these things.
228

    
229
  To protect your rights, we need to make restrictions that forbid
230
anyone to deny you these rights or to ask you to surrender the rights.
231
These restrictions translate to certain responsibilities for you if you
232
distribute copies of the software, or if you modify it.
233

    
234
  For example, if you distribute copies of such a program, whether
235
gratis or for a fee, you must give the recipients all the rights that
236
you have.  You must make sure that they, too, receive or can get the
237
source code.  And you must show them these terms so they know their
238
rights.
239

    
240
  We protect your rights with two steps: (1) copyright the software, and
241
(2) offer you this license which gives you legal permission to copy,
242
distribute and/or modify the software.
243

    
244
  Also, for each author's protection and ours, we want to make certain
245
that everyone understands that there is no warranty for this free
246
software.  If the software is modified by someone else and passed on, we
247
want its recipients to know that what they have is not the original, so
248
that any problems introduced by others will not reflect on the original
249
authors' reputations.
250

    
251
  Finally, any free program is threatened constantly by software
252
patents.  We wish to avoid the danger that redistributors of a free
253
program will individually obtain patent licenses, in effect making the
254
program proprietary.  To prevent this, we have made it clear that any
255
patent must be licensed for everyone's free use or not licensed at all.
256

    
257
  The precise terms and conditions for copying, distribution and
258
modification follow.
259

260
		    GNU GENERAL PUBLIC LICENSE
261
   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
262

    
263
  0. This License applies to any program or other work which contains
264
a notice placed by the copyright holder saying it may be distributed
265
under the terms of this General Public License.  The "Program", below,
266
refers to any such program or work, and a "work based on the Program"
267
means either the Program or any derivative work under copyright law:
268
that is to say, a work containing the Program or a portion of it,
269
either verbatim or with modifications and/or translated into another
270
language.  (Hereinafter, translation is included without limitation in
271
the term "modification".)  Each licensee is addressed as "you".
272

    
273
Activities other than copying, distribution and modification are not
274
covered by this License; they are outside its scope.  The act of
275
running the Program is not restricted, and the output from the Program
276
is covered only if its contents constitute a work based on the
277
Program (independent of having been made by running the Program).
278
Whether that is true depends on what the Program does.
279

    
280
  1. You may copy and distribute verbatim copies of the Program's
281
source code as you receive it, in any medium, provided that you
282
conspicuously and appropriately publish on each copy an appropriate
283
copyright notice and disclaimer of warranty; keep intact all the
284
notices that refer to this License and to the absence of any warranty;
285
and give any other recipients of the Program a copy of this License
286
along with the Program.
287

    
288
You may charge a fee for the physical act of transferring a copy, and
289
you may at your option offer warranty protection in exchange for a fee.
290

    
291
  2. You may modify your copy or copies of the Program or any portion
292
of it, thus forming a work based on the Program, and copy and
293
distribute such modifications or work under the terms of Section 1
294
above, provided that you also meet all of these conditions:
295

    
296
    a) You must cause the modified files to carry prominent notices
297
    stating that you changed the files and the date of any change.
298

    
299
    b) You must cause any work that you distribute or publish, that in
300
    whole or in part contains or is derived from the Program or any
301
    part thereof, to be licensed as a whole at no charge to all third
302
    parties under the terms of this License.
303

    
304
    c) If the modified program normally reads commands interactively
305
    when run, you must cause it, when started running for such
306
    interactive use in the most ordinary way, to print or display an
307
    announcement including an appropriate copyright notice and a
308
    notice that there is no warranty (or else, saying that you provide
309
    a warranty) and that users may redistribute the program under
310
    these conditions, and telling the user how to view a copy of this
311
    License.  (Exception: if the Program itself is interactive but
312
    does not normally print such an announcement, your work based on
313
    the Program is not required to print an announcement.)
314

315
These requirements apply to the modified work as a whole.  If
316
identifiable sections of that work are not derived from the Program,
317
and can be reasonably considered independent and separate works in
318
themselves, then this License, and its terms, do not apply to those
319
sections when you distribute them as separate works.  But when you
320
distribute the same sections as part of a whole which is a work based
321
on the Program, the distribution of the whole must be on the terms of
322
this License, whose permissions for other licensees extend to the
323
entire whole, and thus to each and every part regardless of who wrote it.
324

    
325
Thus, it is not the intent of this section to claim rights or contest
326
your rights to work written entirely by you; rather, the intent is to
327
exercise the right to control the distribution of derivative or
328
collective works based on the Program.
329

    
330
In addition, mere aggregation of another work not based on the Program
331
with the Program (or with a work based on the Program) on a volume of
332
a storage or distribution medium does not bring the other work under
333
the scope of this License.
334

    
335
  3. You may copy and distribute the Program (or a work based on it,
336
under Section 2) in object code or executable form under the terms of
337
Sections 1 and 2 above provided that you also do one of the following:
338

    
339
    a) Accompany it with the complete corresponding machine-readable
340
    source code, which must be distributed under the terms of Sections
341
    1 and 2 above on a medium customarily used for software interchange; or,
342

    
343
    b) Accompany it with a written offer, valid for at least three
344
    years, to give any third party, for a charge no more than your
345
    cost of physically performing source distribution, a complete
346
    machine-readable copy of the corresponding source code, to be
347
    distributed under the terms of Sections 1 and 2 above on a medium
348
    customarily used for software interchange; or,
349

    
350
    c) Accompany it with the information you received as to the offer
351
    to distribute corresponding source code.  (This alternative is
352
    allowed only for noncommercial distribution and only if you
353
    received the program in object code or executable form with such
354
    an offer, in accord with Subsection b above.)
355

    
356
The source code for a work means the preferred form of the work for
357
making modifications to it.  For an executable work, complete source
358
code means all the source code for all modules it contains, plus any
359
associated interface definition files, plus the scripts used to
360
control compilation and installation of the executable.  However, as a
361
special exception, the source code distributed need not include
362
anything that is normally distributed (in either source or binary
363
form) with the major components (compiler, kernel, and so on) of the
364
operating system on which the executable runs, unless that component
365
itself accompanies the executable.
366

    
367
If distribution of executable or object code is made by offering
368
access to copy from a designated place, then offering equivalent
369
access to copy the source code from the same place counts as
370
distribution of the source code, even though third parties are not
371
compelled to copy the source along with the object code.
372

373
  4. You may not copy, modify, sublicense, or distribute the Program
374
except as expressly provided under this License.  Any attempt
375
otherwise to copy, modify, sublicense or distribute the Program is
376
void, and will automatically terminate your rights under this License.
377
However, parties who have received copies, or rights, from you under
378
this License will not have their licenses terminated so long as such
379
parties remain in full compliance.
380

    
381
  5. You are not required to accept this License, since you have not
382
signed it.  However, nothing else grants you permission to modify or
383
distribute the Program or its derivative works.  These actions are
384
prohibited by law if you do not accept this License.  Therefore, by
385
modifying or distributing the Program (or any work based on the
386
Program), you indicate your acceptance of this License to do so, and
387
all its terms and conditions for copying, distributing or modifying
388
the Program or works based on it.
389

    
390
  6. Each time you redistribute the Program (or any work based on the
391
Program), the recipient automatically receives a license from the
392
original licensor to copy, distribute or modify the Program subject to
393
these terms and conditions.  You may not impose any further
394
restrictions on the recipients' exercise of the rights granted herein.
395
You are not responsible for enforcing compliance by third parties to
396
this License.
397

    
398
  7. If, as a consequence of a court judgment or allegation of patent
399
infringement or for any other reason (not limited to patent issues),
400
conditions are imposed on you (whether by court order, agreement or
401
otherwise) that contradict the conditions of this License, they do not
402
excuse you from the conditions of this License.  If you cannot
403
distribute so as to satisfy simultaneously your obligations under this
404
License and any other pertinent obligations, then as a consequence you
405
may not distribute the Program at all.  For example, if a patent
406
license would not permit royalty-free redistribution of the Program by
407
all those who receive copies directly or indirectly through you, then
408
the only way you could satisfy both it and this License would be to
409
refrain entirely from distribution of the Program.
410

    
411
If any portion of this section is held invalid or unenforceable under
412
any particular circumstance, the balance of the section is intended to
413
apply and the section as a whole is intended to apply in other
414
circumstances.
415

    
416
It is not the purpose of this section to induce you to infringe any
417
patents or other property right claims or to contest validity of any
418
such claims; this section has the sole purpose of protecting the
419
integrity of the free software distribution system, which is
420
implemented by public license practices.  Many people have made
421
generous contributions to the wide range of software distributed
422
through that system in reliance on consistent application of that
423
system; it is up to the author/donor to decide if he or she is willing
424
to distribute software through any other system and a licensee cannot
425
impose that choice.
426

    
427
This section is intended to make thoroughly clear what is believed to
428
be a consequence of the rest of this License.
429

430
  8. If the distribution and/or use of the Program is restricted in
431
certain countries either by patents or by copyrighted interfaces, the
432
original copyright holder who places the Program under this License
433
may add an explicit geographical distribution limitation excluding
434
those countries, so that distribution is permitted only in or among
435
countries not thus excluded.  In such case, this License incorporates
436
the limitation as if written in the body of this License.
437

    
438
  9. The Free Software Foundation may publish revised and/or new versions
439
of the General Public License from time to time.  Such new versions will
440
be similar in spirit to the present version, but may differ in detail to
441
address new problems or concerns.
442

    
443
Each version is given a distinguishing version number.  If the Program
444
specifies a version number of this License which applies to it and "any
445
later version", you have the option of following the terms and conditions
446
either of that version or of any later version published by the Free
447
Software Foundation.  If the Program does not specify a version number of
448
this License, you may choose any version ever published by the Free Software
449
Foundation.
450

    
451
  10. If you wish to incorporate parts of the Program into other free
452
programs whose distribution conditions are different, write to the author
453
to ask for permission.  For software which is copyrighted by the Free
454
Software Foundation, write to the Free Software Foundation; we sometimes
455
make exceptions for this.  Our decision will be guided by the two goals
456
of preserving the free status of all derivatives of our free software and
457
of promoting the sharing and reuse of software generally.
458

    
459
			    NO WARRANTY
460

    
461
  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
462
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
463
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
464
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
465
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
466
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
467
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
468
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
469
REPAIR OR CORRECTION.
470

    
471
  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
472
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
473
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
474
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
475
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
476
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
477
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
478
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
479
POSSIBILITY OF SUCH DAMAGES.
480

	Appendix: How to Apply These Terms to Your New Programs
484

    
485
  If you develop a new program, and you want it to be of the greatest
486
possible use to the public, the best way to achieve this is to make it
487
free software which everyone can redistribute and change under these terms.
488

    
489
  To do so, attach the following notices to the program.  It is safest
490
to attach them to the start of each source file to most effectively
491
convey the exclusion of warranty; and each file should have at least
492
the "copyright" line and a pointer to where the full notice is found.
493

    
494
    <one line to give the program's name and a brief idea of what it does.>
495
    Copyright (C) 19yy  <name of author>
496

    
497
    This program is free software; you can redistribute it and/or modify
498
    it under the terms of the GNU General Public License as published by
499
    the Free Software Foundation; either version 2 of the License, or
500
    (at your option) any later version.
501

    
502
    This program is distributed in the hope that it will be useful,
503
    but WITHOUT ANY WARRANTY; without even the implied warranty of
504
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
505
    GNU General Public License for more details.
506

    
507
    You should have received a copy of the GNU General Public License
508
    along with this program; if not, write to the Free Software
509
    Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
510

    
511
Also add information on how to contact you by electronic and paper mail.
512

    
513
If the program is interactive, make it output a short notice like this
514
when it starts in an interactive mode:
515

    
516
    Gnomovision version 69, Copyright (C) 19yy name of author
517
    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
518
    This is free software, and you are welcome to redistribute it
519
    under certain conditions; type `show c' for details.
520

    
521
The hypothetical commands `show w' and `show c' should show the appropriate
522
parts of the General Public License.  Of course, the commands you use may
523
be called something other than `show w' and `show c'; they could even be
524
mouse-clicks or menu items--whatever suits your program.
525

    
526
You should also get your employer (if you work as a programmer) or your
527
school, if any, to sign a "copyright disclaimer" for the program, if
528
necessary.  Here is a sample; alter the names:
529

    
530
  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
531
  `Gnomovision' (which makes passes at compilers) written by James Hacker.
532

536
This General Public License does not permit incorporating your program into
537
proprietary programs.  If your program is a subroutine library, you may
538
consider it more useful to permit linking proprietary applications with the
539
library.  If this is what you want to do, use the GNU Library General
540
Public License instead of this License.
