9+		    GNU GENERAL PUBLIC LICENSE
10+		       Version 2, June 1991
11+
12+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
13+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
14+ Everyone is permitted to copy and distribute verbatim copies
15+ of this license document, but changing it is not allowed.
16+
17+			    Preamble
18+
19+  The licenses for most software are designed to take away your
20+freedom to share and change it.  By contrast, the GNU General Public
21+License is intended to guarantee your freedom to share and change free
22+software--to make sure the software is free for all its users.  This
23+General Public License applies to most of the Free Software
24+Foundation's software and to any other program whose authors commit to
25+using it.  (Some other Free Software Foundation software is covered by
26+the GNU Lesser General Public License instead.)  You can apply it to
27+your programs, too.
28+
29+  When we speak of free software, we are referring to freedom, not
30+price.  Our General Public Licenses are designed to make sure that you
31+have the freedom to distribute copies of free software (and charge for
32+this service if you wish), that you receive source code or can get it
33+if you want it, that you can change the software or use pieces of it
34+in new free programs; and that you know you can do these things.
35+
36+  To protect your rights, we need to make restrictions that forbid
37+anyone to deny you these rights or to ask you to surrender the rights.
38+These restrictions translate to certain responsibilities for you if you
39+distribute copies of the software, or if you modify it.
40+
41+  For example, if you distribute copies of such a program, whether
42+gratis or for a fee, you must give the recipients all the rights that
43+you have.  You must make sure that they, too, receive or can get the
44+source code.  And you must show them these terms so they know their
45+rights.
46+
47+  We protect your rights with two steps: (1) copyright the software, and
48+(2) offer you this license which gives you legal permission to copy,
49+distribute and/or modify the software.
50+
51+  Also, for each author's protection and ours, we want to make certain
52+that everyone understands that there is no warranty for this free
53+software.  If the software is modified by someone else and passed on, we
54+want its recipients to know that what they have is not the original, so
55+that any problems introduced by others will not reflect on the original
56+authors' reputations.
57+
58+  Finally, any free program is threatened constantly by software
59+patents.  We wish to avoid the danger that redistributors of a free
60+program will individually obtain patent licenses, in effect making the
61+program proprietary.  To prevent this, we have made it clear that any
62+patent must be licensed for everyone's free use or not licensed at all.
63+
64+  The precise terms and conditions for copying, distribution and
65+modification follow.
66+
67+		    GNU GENERAL PUBLIC LICENSE
68+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
69+
70+  0. This License applies to any program or other work which contains
71+a notice placed by the copyright holder saying it may be distributed
72+under the terms of this General Public License.  The "Program", below,
73+refers to any such program or work, and a "work based on the Program"
74+means either the Program or any derivative work under copyright law:
75+that is to say, a work containing the Program or a portion of it,
76+either verbatim or with modifications and/or translated into another
77+language.  (Hereinafter, translation is included without limitation in
78+the term "modification".)  Each licensee is addressed as "you".
79+
80+Activities other than copying, distribution and modification are not
81+covered by this License; they are outside its scope.  The act of
82+running the Program is not restricted, and the output from the Program
83+is covered only if its contents constitute a work based on the
84+Program (independent of having been made by running the Program).
85+Whether that is true depends on what the Program does.
86+
87+  1. You may copy and distribute verbatim copies of the Program's
88+source code as you receive it, in any medium, provided that you
89+conspicuously and appropriately publish on each copy an appropriate
90+copyright notice and disclaimer of warranty; keep intact all the
91+notices that refer to this License and to the absence of any warranty;
92+and give any other recipients of the Program a copy of this License
93+along with the Program.
94+
95+You may charge a fee for the physical act of transferring a copy, and
96+you may at your option offer warranty protection in exchange for a fee.
97+
98+  2. You may modify your copy or copies of the Program or any portion
99+of it, thus forming a work based on the Program, and copy and
100+distribute such modifications or work under the terms of Section 1
101+above, provided that you also meet all of these conditions:
102+
103+    a) You must cause the modified files to carry prominent notices
104+    stating that you changed the files and the date of any change.
105+
106+    b) You must cause any work that you distribute or publish, that in
107+    whole or in part contains or is derived from the Program or any
108+    part thereof, to be licensed as a whole at no charge to all third
109+    parties under the terms of this License.
110+
111+    c) If the modified program normally reads commands interactively
112+    when run, you must cause it, when started running for such
113+    interactive use in the most ordinary way, to print or display an
114+    announcement including an appropriate copyright notice and a
115+    notice that there is no warranty (or else, saying that you provide
116+    a warranty) and that users may redistribute the program under
117+    these conditions, and telling the user how to view a copy of this
118+    License.  (Exception: if the Program itself is interactive but
119+    does not normally print such an announcement, your work based on
120+    the Program is not required to print an announcement.)
121+
122+These requirements apply to the modified work as a whole.  If
123+identifiable sections of that work are not derived from the Program,
124+and can be reasonably considered independent and separate works in
125+themselves, then this License, and its terms, do not apply to those
126+sections when you distribute them as separate works.  But when you
127+distribute the same sections as part of a whole which is a work based
128+on the Program, the distribution of the whole must be on the terms of
129+this License, whose permissions for other licensees extend to the
130+entire whole, and thus to each and every part regardless of who wrote it.
131+
132+Thus, it is not the intent of this section to claim rights or contest
133+your rights to work written entirely by you; rather, the intent is to
134+exercise the right to control the distribution of derivative or
135+collective works based on the Program.
136+
137+In addition, mere aggregation of another work not based on the Program
138+with the Program (or with a work based on the Program) on a volume of
139+a storage or distribution medium does not bring the other work under
140+the scope of this License.
141+
142+  3. You may copy and distribute the Program (or a work based on it,
143+under Section 2) in object code or executable form under the terms of
144+Sections 1 and 2 above provided that you also do one of the following:
145+
146+    a) Accompany it with the complete corresponding machine-readable
147+    source code, which must be distributed under the terms of Sections
148+    1 and 2 above on a medium customarily used for software interchange; or,
149+
150+    b) Accompany it with a written offer, valid for at least three
151+    years, to give any third party, for a charge no more than your
152+    cost of physically performing source distribution, a complete
153+    machine-readable copy of the corresponding source code, to be
154+    distributed under the terms of Sections 1 and 2 above on a medium
155+    customarily used for software interchange; or,
156+
157+    c) Accompany it with the information you received as to the offer
158+    to distribute corresponding source code.  (This alternative is
159+    allowed only for noncommercial distribution and only if you
160+    received the program in object code or executable form with such
161+    an offer, in accord with Subsection b above.)
162+
163+The source code for a work means the preferred form of the work for
164+making modifications to it.  For an executable work, complete source
165+code means all the source code for all modules it contains, plus any
166+associated interface definition files, plus the scripts used to
167+control compilation and installation of the executable.  However, as a
168+special exception, the source code distributed need not include
169+anything that is normally distributed (in either source or binary
170+form) with the major components (compiler, kernel, and so on) of the
171+operating system on which the executable runs, unless that component
172+itself accompanies the executable.
173+
174+If distribution of executable or object code is made by offering
175+access to copy from a designated place, then offering equivalent
176+access to copy the source code from the same place counts as
177+distribution of the source code, even though third parties are not
178+compelled to copy the source along with the object code.
179+
180+  4. You may not copy, modify, sublicense, or distribute the Program
181+except as expressly provided under this License.  Any attempt
182+otherwise to copy, modify, sublicense or distribute the Program is
183+void, and will automatically terminate your rights under this License.
184+However, parties who have received copies, or rights, from you under
185+this License will not have their licenses terminated so long as such
186+parties remain in full compliance.
187+
188+  5. You are not required to accept this License, since you have not
189+signed it.  However, nothing else grants you permission to modify or
190+distribute the Program or its derivative works.  These actions are
191+prohibited by law if you do not accept this License.  Therefore, by
192+modifying or distributing the Program (or any work based on the
193+Program), you indicate your acceptance of this License to do so, and
194+all its terms and conditions for copying, distributing or modifying
195+the Program or works based on it.
196+
197+  6. Each time you redistribute the Program (or any work based on the
198+Program), the recipient automatically receives a license from the
199+original licensor to copy, distribute or modify the Program subject to
200+these terms and conditions.  You may not impose any further
201+restrictions on the recipients' exercise of the rights granted herein.
202+You are not responsible for enforcing compliance by third parties to
203+this License.
204+
205+  7. If, as a consequence of a court judgment or allegation of patent
206+infringement or for any other reason (not limited to patent issues),
207+conditions are imposed on you (whether by court order, agreement or
208+otherwise) that contradict the conditions of this License, they do not
209+excuse you from the conditions of this License.  If you cannot
210+distribute so as to satisfy simultaneously your obligations under this
211+License and any other pertinent obligations, then as a consequence you
212+may not distribute the Program at all.  For example, if a patent
213+license would not permit royalty-free redistribution of the Program by
214+all those who receive copies directly or indirectly through you, then
215+the only way you could satisfy both it and this License would be to
216+refrain entirely from distribution of the Program.
217+
218+If any portion of this section is held invalid or unenforceable under
219+any particular circumstance, the balance of the section is intended to
220+apply and the section as a whole is intended to apply in other
221+circumstances.
222+
223+It is not the purpose of this section to induce you to infringe any
224+patents or other property right claims or to contest validity of any
225+such claims; this section has the sole purpose of protecting the
226+integrity of the free software distribution system, which is
227+implemented by public license practices.  Many people have made
228+generous contributions to the wide range of software distributed
229+through that system in reliance on consistent application of that
230+system; it is up to the author/donor to decide if he or she is willing
231+to distribute software through any other system and a licensee cannot
232+impose that choice.
233+
234+This section is intended to make thoroughly clear what is believed to
235+be a consequence of the rest of this License.
236+
237+  8. If the distribution and/or use of the Program is restricted in
238+certain countries either by patents or by copyrighted interfaces, the
239+original copyright holder who places the Program under this License
240+may add an explicit geographical distribution limitation excluding
241+those countries, so that distribution is permitted only in or among
242+countries not thus excluded.  In such case, this License incorporates
243+the limitation as if written in the body of this License.
244+
245+  9. The Free Software Foundation may publish revised and/or new versions
246+of the General Public License from time to time.  Such new versions will
247+be similar in spirit to the present version, but may differ in detail to
248+address new problems or concerns.
249+
250+Each version is given a distinguishing version number.  If the Program
251+specifies a version number of this License which applies to it and "any
252+later version", you have the option of following the terms and conditions
253+either of that version or of any later version published by the Free
254+Software Foundation.  If the Program does not specify a version number of
255+this License, you may choose any version ever published by the Free Software
256+Foundation.
257+
258+  10. If you wish to incorporate parts of the Program into other free
259+programs whose distribution conditions are different, write to the author
260+to ask for permission.  For software which is copyrighted by the Free
261+Software Foundation, write to the Free Software Foundation; we sometimes
262+make exceptions for this.  Our decision will be guided by the two goals
263+of preserving the free status of all derivatives of our free software and
264+of promoting the sharing and reuse of software generally.
265+
266+			    NO WARRANTY
267+
268+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
269+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
270+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
271+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
272+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
273+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
274+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
275+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
276+REPAIR OR CORRECTION.
277+
278+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
279+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
280+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
281+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
282+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
283+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
284+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
285+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
286+POSSIBILITY OF SUCH DAMAGES.
287+
288+		     END OF TERMS AND CONDITIONS
289+
290+	    How to Apply These Terms to Your New Programs
291+
292+  If you develop a new program, and you want it to be of the greatest
293+possible use to the public, the best way to achieve this is to make it
294+free software which everyone can redistribute and change under these terms.
295+
296+  To do so, attach the following notices to the program.  It is safest
297+to attach them to the start of each source file to most effectively
298+convey the exclusion of warranty; and each file should have at least
299+the "copyright" line and a pointer to where the full notice is found.
300+
301+    <one line to give the program's name and a brief idea of what it does.>
302+    Copyright (C) <year>  <name of author>
303+
304+    This program is free software; you can redistribute it and/or modify
305+    it under the terms of the GNU General Public License as published by
306+    the Free Software Foundation; either version 2 of the License, or
307+    (at your option) any later version.
308+
309+    This program is distributed in the hope that it will be useful,
310+    but WITHOUT ANY WARRANTY; without even the implied warranty of
311+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
312+    GNU General Public License for more details.
313+
314+    You should have received a copy of the GNU General Public License along
315+    with this program; if not, write to the Free Software Foundation, Inc.,
316+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
317+
318+Also add information on how to contact you by electronic and paper mail.
319+
320+If the program is interactive, make it output a short notice like this
321+when it starts in an interactive mode:
322+
323+    Gnomovision version 69, Copyright (C) year name of author
324+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
325+    This is free software, and you are welcome to redistribute it
326+    under certain conditions; type `show c' for details.
327+
328+The hypothetical commands `show w' and `show c' should show the appropriate
329+parts of the General Public License.  Of course, the commands you use may
330+be called something other than `show w' and `show c'; they could even be
331+mouse-clicks or menu items--whatever suits your program.
332+
333+You should also get your employer (if you work as a programmer) or your
334+school, if any, to sign a "copyright disclaimer" for the program, if
335+necessary.  Here is a sample; alter the names:
336+
337+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
338+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
339+
340+  <signature of Ty Coon>, 1 April 1989
341+  Ty Coon, President of Vice
342+
343+This General Public License does not permit incorporating your program into
344+proprietary programs.  If your program is a subroutine library, you may
345+consider it more useful to permit linking proprietary applications with the
346+library.  If this is what you want to do, use the GNU Lesser General
347+Public License instead of this License.
348
