1The software in this package is distributed under the GNU General Public
2License (with a special exception described below as 13th term).
3
4        GNU GENERAL PUBLIC LICENSE
5           Version 2, June 1991
6
7 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
8                       59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
9 Everyone is permitted to copy and distribute verbatim copies
10 of this license document, but changing it is not allowed.
11
12          Preamble
13
14  The licenses for most software are designed to take away your
15freedom to share and change it.  By contrast, the GNU General Public
16License is intended to guarantee your freedom to share and change free
17software--to make sure the software is free for all its users.  This
18General Public License applies to most of the Free Software
19Foundation's software and to any other program whose authors commit to
20using it.  (Some other Free Software Foundation software is covered by
21the GNU Library General Public License instead.)  You can apply it to
22your programs, too.
23
24  When we speak of free software, we are referring to freedom, not
25price.  Our General Public Licenses are designed to make sure that you
26have the freedom to distribute copies of free software (and charge for
27this service if you wish), that you receive source code or can get it
28if you want it, that you can change the software or use pieces of it
29in new free programs; and that you know you can do these things.
30
31  To protect your rights, we need to make restrictions that forbid
32anyone to deny you these rights or to ask you to surrender the rights.
33These restrictions translate to certain responsibilities for you if you
34distribute copies of the software, or if you modify it.
35
36  For example, if you distribute copies of such a program, whether
37gratis or for a fee, you must give the recipients all the rights that
38you have.  You must make sure that they, too, receive or can get the
39source code.  And you must show them these terms so they know their
40rights.
41
42  We protect your rights with two steps: (1) copyright the software, and
43(2) offer you this license which gives you legal permission to copy,
44distribute and/or modify the software.
45
46  Also, for each author's protection and ours, we want to make certain
47that everyone understands that there is no warranty for this free
48software.  If the software is modified by someone else and passed on, we
49want its recipients to know that what they have is not the original, so
50that any problems introduced by others will not reflect on the original
51authors' reputations.
52
53  Finally, any free program is threatened constantly by software
54patents.  We wish to avoid the danger that redistributors of a free
55program will individually obtain patent licenses, in effect making the
56program proprietary.  To prevent this, we have made it clear that any
57patent must be licensed for everyone's free use or not licensed at all.
58
59  The precise terms and conditions for copying, distribution and
60modification follow.
61
62        GNU GENERAL PUBLIC LICENSE
63   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
64
65  0. This License applies to any program or other work which contains
66a notice placed by the copyright holder saying it may be distributed
67under the terms of this General Public License.  The "Program", below,
68refers to any such program or work, and a "work based on the Program"
69means either the Program or any derivative work under copyright law:
70that is to say, a work containing the Program or a portion of it,
71either verbatim or with modifications and/or translated into another
72language.  (Hereinafter, translation is included without limitation in
73the term "modification".)  Each licensee is addressed as "you".
74
75Activities other than copying, distribution and modification are not
76covered by this License; they are outside its scope.  The act of
77running the Program is not restricted, and the output from the Program
78is covered only if its contents constitute a work based on the
79Program (independent of having been made by running the Program).
80Whether that is true depends on what the Program does.
81
82  1. You may copy and distribute verbatim copies of the Program's
83source code as you receive it, in any medium, provided that you
84conspicuously and appropriately publish on each copy an appropriate
85copyright notice and disclaimer of warranty; keep intact all the
86notices that refer to this License and to the absence of any warranty;
87and give any other recipients of the Program a copy of this License
88along with the Program.
89
90You may charge a fee for the physical act of transferring a copy, and
91you may at your option offer warranty protection in exchange for a fee.
92
93  2. You may modify your copy or copies of the Program or any portion
94of it, thus forming a work based on the Program, and copy and
95distribute such modifications or work under the terms of Section 1
96above, provided that you also meet all of these conditions:
97
98    a) You must cause the modified files to carry prominent notices
99    stating that you changed the files and the date of any change.
100
101    b) You must cause any work that you distribute or publish, that in
102    whole or in part contains or is derived from the Program or any
103    part thereof, to be licensed as a whole at no charge to all third
104    parties under the terms of this License.
105
106    c) If the modified program normally reads commands interactively
107    when run, you must cause it, when started running for such
108    interactive use in the most ordinary way, to print or display an
109    announcement including an appropriate copyright notice and a
110    notice that there is no warranty (or else, saying that you provide
111    a warranty) and that users may redistribute the program under
112    these conditions, and telling the user how to view a copy of this
113    License.  (Exception: if the Program itself is interactive but
114    does not normally print such an announcement, your work based on
115    the Program is not required to print an announcement.)
116
117These requirements apply to the modified work as a whole.  If
118identifiable sections of that work are not derived from the Program,
119and can be reasonably considered independent and separate works in
120themselves, then this License, and its terms, do not apply to those
121sections when you distribute them as separate works.  But when you
122distribute the same sections as part of a whole which is a work based
123on the Program, the distribution of the whole must be on the terms of
124this License, whose permissions for other licensees extend to the
125entire whole, and thus to each and every part regardless of who wrote it.
126
127Thus, it is not the intent of this section to claim rights or contest
128your rights to work written entirely by you; rather, the intent is to
129exercise the right to control the distribution of derivative or
130collective works based on the Program.
131
132In addition, mere aggregation of another work not based on the Program
133with the Program (or with a work based on the Program) on a volume of
134a storage or distribution medium does not bring the other work under
135the scope of this License.
136
137  3. You may copy and distribute the Program (or a work based on it,
138under Section 2) in object code or executable form under the terms of
139Sections 1 and 2 above provided that you also do one of the following:
140
141    a) Accompany it with the complete corresponding machine-readable
142    source code, which must be distributed under the terms of Sections
143    1 and 2 above on a medium customarily used for software interchange; or,
144
145    b) Accompany it with a written offer, valid for at least three
146    years, to give any third party, for a charge no more than your
147    cost of physically performing source distribution, a complete
148    machine-readable copy of the corresponding source code, to be
149    distributed under the terms of Sections 1 and 2 above on a medium
150    customarily used for software interchange; or,
151
152    c) Accompany it with the information you received as to the offer
153    to distribute corresponding source code.  (This alternative is
154    allowed only for noncommercial distribution and only if you
155    received the program in object code or executable form with such
156    an offer, in accord with Subsection b above.)
157
158The source code for a work means the preferred form of the work for
159making modifications to it.  For an executable work, complete source
160code means all the source code for all modules it contains, plus any
161associated interface definition files, plus the scripts used to
162control compilation and installation of the executable.  However, as a
163special exception, the source code distributed need not include
164anything that is normally distributed (in either source or binary
165form) with the major components (compiler, kernel, and so on) of the
166operating system on which the executable runs, unless that component
167itself accompanies the executable.
168
169If distribution of executable or object code is made by offering
170access to copy from a designated place, then offering equivalent
171access to copy the source code from the same place counts as
172distribution of the source code, even though third parties are not
173compelled to copy the source along with the object code.
174
175  4. You may not copy, modify, sublicense, or distribute the Program
176except as expressly provided under this License.  Any attempt
177otherwise to copy, modify, sublicense or distribute the Program is
178void, and will automatically terminate your rights under this License.
179However, parties who have received copies, or rights, from you under
180this License will not have their licenses terminated so long as such
181parties remain in full compliance.
182
183  5. You are not required to accept this License, since you have not
184signed it.  However, nothing else grants you permission to modify or
185distribute the Program or its derivative works.  These actions are
186prohibited by law if you do not accept this License.  Therefore, by
187modifying or distributing the Program (or any work based on the
188Program), you indicate your acceptance of this License to do so, and
189all its terms and conditions for copying, distributing or modifying
190the Program or works based on it.
191
192  6. Each time you redistribute the Program (or any work based on the
193Program), the recipient automatically receives a license from the
194original licensor to copy, distribute or modify the Program subject to
195these terms and conditions.  You may not impose any further
196restrictions on the recipients' exercise of the rights granted herein.
197You are not responsible for enforcing compliance by third parties to
198this License.
199
200  7. If, as a consequence of a court judgment or allegation of patent
201infringement or for any other reason (not limited to patent issues),
202conditions are imposed on you (whether by court order, agreement or
203otherwise) that contradict the conditions of this License, they do not
204excuse you from the conditions of this License.  If you cannot
205distribute so as to satisfy simultaneously your obligations under this
206License and any other pertinent obligations, then as a consequence you
207may not distribute the Program at all.  For example, if a patent
208license would not permit royalty-free redistribution of the Program by
209all those who receive copies directly or indirectly through you, then
210the only way you could satisfy both it and this License would be to
211refrain entirely from distribution of the Program.
212
213If any portion of this section is held invalid or unenforceable under
214any particular circumstance, the balance of the section is intended to
215apply and the section as a whole is intended to apply in other
216circumstances.
217
218It is not the purpose of this section to induce you to infringe any
219patents or other property right claims or to contest validity of any
220such claims; this section has the sole purpose of protecting the
221integrity of the free software distribution system, which is
222implemented by public license practices.  Many people have made
223generous contributions to the wide range of software distributed
224through that system in reliance on consistent application of that
225system; it is up to the author/donor to decide if he or she is willing
226to distribute software through any other system and a licensee cannot
227impose that choice.
228
229This section is intended to make thoroughly clear what is believed to
230be a consequence of the rest of this License.
231
232  8. If the distribution and/or use of the Program is restricted in
233certain countries either by patents or by copyrighted interfaces, the
234original copyright holder who places the Program under this License
235may add an explicit geographical distribution limitation excluding
236those countries, so that distribution is permitted only in or among
237countries not thus excluded.  In such case, this License incorporates
238the limitation as if written in the body of this License.
239
240  9. The Free Software Foundation may publish revised and/or new versions
241of the General Public License from time to time.  Such new versions will
242be similar in spirit to the present version, but may differ in detail to
243address new problems or concerns.
244
245Each version is given a distinguishing version number.  If the Program
246specifies a version number of this License which applies to it and "any
247later version", you have the option of following the terms and conditions
248either of that version or of any later version published by the Free
249Software Foundation.  If the Program does not specify a version number of
250this License, you may choose any version ever published by the Free Software
251Foundation.
252
253  10. If you wish to incorporate parts of the Program into other free
254programs whose distribution conditions are different, write to the author
255to ask for permission.  For software which is copyrighted by the Free
256Software Foundation, write to the Free Software Foundation; we sometimes
257make exceptions for this.  Our decision will be guided by the two goals
258of preserving the free status of all derivatives of our free software and
259of promoting the sharing and reuse of software generally.
260
261          NO WARRANTY
262
263  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
264WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
265EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
266OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY
267KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
268IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
269PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
270PROGRAM IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME
271THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
272
273  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
274WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
275AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU
276FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
277CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
278PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
279RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
280FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF
281SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
282DAMAGES.
283
284  13. Linking this library statically or dynamically with other
285  modules is making a combined work based on this library. Thus, the
286  terms and conditions of the GNU General Public License cover the
287  whole combination.
288
289  The following paragraph details the "classpath exception" which ABCL
290  allows as an exception to the statement about linking libraries.
291
292  As a special exception, the copyright holders of this software give
293  you permission to link this software with independent modules to
294  produce an executable, regardless of the license terms of these
295  independent modules, and to copy and distribute the resulting
296  executable under terms of your choice, provided that you also meet,
297  for each linked independent module, the terms and conditions of the
298  license of that module. An independent module is a module which is
299  not derived from or based on this software. If you modify this
300  software, you may extend this exception to your version of the
301  software, but you are not obligated to do so. If you do not wish to
302  do so, delete this exception statement from your version.
303
304
305         END OF TERMS AND CONDITIONS
306
307      How to Apply These Terms to Your New Programs
308
309  If you develop a new program, and you want it to be of the greatest
310possible use to the public, the best way to achieve this is to make it
311free software which everyone can redistribute and change under these terms.
312
313  To do so, attach the following notices to the program.  It is safest
314to attach them to the start of each source file to most effectively
315convey the exclusion of warranty; and each file should have at least
316the "copyright" line and a pointer to where the full notice is found.
317
318    <one line to give the program's name and a brief idea of what it does.>
319    Copyright (C) 19yy  <name of author>
320
321    This program is free software; you can redistribute it and/or modify
322    it under the terms of the GNU General Public License as published by
323    the Free Software Foundation; either version 2 of the License, or
324    (at your option) any later version.
325
326    This program is distributed in the hope that it will be useful,
327    but WITHOUT ANY WARRANTY; without even the implied warranty of
328    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
329    GNU General Public License for more details.
330
331    You should have received a copy of the GNU General Public License
332    along with this program; if not, write to the Free Software
333    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
334
335
336Also add information on how to contact you by electronic and paper mail.
337
338If the program is interactive, make it output a short notice like this
339when it starts in an interactive mode:
340
341    Gnomovision version 69, Copyright (C) 19yy name of author
342    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
343    This is free software, and you are welcome to redistribute it
344    under certain conditions; type `show c' for details.
345
346The hypothetical commands `show w' and `show c' should show the appropriate
347parts of the General Public License.  Of course, the commands you use may
348be called something other than `show w' and `show c'; they could even be
349mouse-clicks or menu items--whatever suits your program.
350
351You should also get your employer (if you work as a programmer) or your
352school, if any, to sign a "copyright disclaimer" for the program, if
353necessary.  Here is a sample; alter the names:
354
355  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
356  `Gnomovision' (which makes passes at compilers) written by James Hacker.
