10*2587624eSSzymon Olewniczak
11*2587624eSSzymon Olewniczak  The licenses for most software are designed to take away your
12*2587624eSSzymon Olewniczakfreedom to share and change it.  By contrast, the GNU General Public
13*2587624eSSzymon OlewniczakLicense is intended to guarantee your freedom to share and change free
14*2587624eSSzymon Olewniczaksoftware--to make sure the software is free for all its users.  This
15*2587624eSSzymon OlewniczakGeneral Public License applies to most of the Free Software
16*2587624eSSzymon OlewniczakFoundation's software and to any other program whose authors commit to
17*2587624eSSzymon Olewniczakusing it.  (Some other Free Software Foundation software is covered by
18*2587624eSSzymon Olewniczakthe GNU Lesser General Public License instead.)  You can apply it to
19*2587624eSSzymon Olewniczakyour programs, too.
20*2587624eSSzymon Olewniczak
21*2587624eSSzymon Olewniczak  When we speak of free software, we are referring to freedom, not
22*2587624eSSzymon Olewniczakprice.  Our General Public Licenses are designed to make sure that you
23*2587624eSSzymon Olewniczakhave the freedom to distribute copies of free software (and charge for
24*2587624eSSzymon Olewniczakthis service if you wish), that you receive source code or can get it
25*2587624eSSzymon Olewniczakif you want it, that you can change the software or use pieces of it
26*2587624eSSzymon Olewniczakin new free programs; and that you know you can do these things.
27*2587624eSSzymon Olewniczak
28*2587624eSSzymon Olewniczak  To protect your rights, we need to make restrictions that forbid
29*2587624eSSzymon Olewniczakanyone to deny you these rights or to ask you to surrender the rights.
30*2587624eSSzymon OlewniczakThese restrictions translate to certain responsibilities for you if you
31*2587624eSSzymon Olewniczakdistribute copies of the software, or if you modify it.
32*2587624eSSzymon Olewniczak
33*2587624eSSzymon Olewniczak  For example, if you distribute copies of such a program, whether
34*2587624eSSzymon Olewniczakgratis or for a fee, you must give the recipients all the rights that
35*2587624eSSzymon Olewniczakyou have.  You must make sure that they, too, receive or can get the
36*2587624eSSzymon Olewniczaksource code.  And you must show them these terms so they know their
37*2587624eSSzymon Olewniczakrights.
38*2587624eSSzymon Olewniczak
39*2587624eSSzymon Olewniczak  We protect your rights with two steps: (1) copyright the software, and
40*2587624eSSzymon Olewniczak(2) offer you this license which gives you legal permission to copy,
41*2587624eSSzymon Olewniczakdistribute and/or modify the software.
42*2587624eSSzymon Olewniczak
43*2587624eSSzymon Olewniczak  Also, for each author's protection and ours, we want to make certain
44*2587624eSSzymon Olewniczakthat everyone understands that there is no warranty for this free
45*2587624eSSzymon Olewniczaksoftware.  If the software is modified by someone else and passed on, we
46*2587624eSSzymon Olewniczakwant its recipients to know that what they have is not the original, so
47*2587624eSSzymon Olewniczakthat any problems introduced by others will not reflect on the original
48*2587624eSSzymon Olewniczakauthors' reputations.
49*2587624eSSzymon Olewniczak
50*2587624eSSzymon Olewniczak  Finally, any free program is threatened constantly by software
51*2587624eSSzymon Olewniczakpatents.  We wish to avoid the danger that redistributors of a free
52*2587624eSSzymon Olewniczakprogram will individually obtain patent licenses, in effect making the
53*2587624eSSzymon Olewniczakprogram proprietary.  To prevent this, we have made it clear that any
54*2587624eSSzymon Olewniczakpatent must be licensed for everyone's free use or not licensed at all.
55*2587624eSSzymon Olewniczak
56*2587624eSSzymon Olewniczak  The precise terms and conditions for copying, distribution and
57*2587624eSSzymon Olewniczakmodification follow.
58*2587624eSSzymon Olewniczak
59*2587624eSSzymon Olewniczak                    GNU GENERAL PUBLIC LICENSE
60*2587624eSSzymon Olewniczak   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
61*2587624eSSzymon Olewniczak
62*2587624eSSzymon Olewniczak  0. This License applies to any program or other work which contains
63*2587624eSSzymon Olewniczaka notice placed by the copyright holder saying it may be distributed
64*2587624eSSzymon Olewniczakunder the terms of this General Public License.  The "Program", below,
65*2587624eSSzymon Olewniczakrefers to any such program or work, and a "work based on the Program"
66*2587624eSSzymon Olewniczakmeans either the Program or any derivative work under copyright law:
67*2587624eSSzymon Olewniczakthat is to say, a work containing the Program or a portion of it,
68*2587624eSSzymon Olewniczakeither verbatim or with modifications and/or translated into another
69*2587624eSSzymon Olewniczaklanguage.  (Hereinafter, translation is included without limitation in
70*2587624eSSzymon Olewniczakthe term "modification".)  Each licensee is addressed as "you".
71*2587624eSSzymon Olewniczak
72*2587624eSSzymon OlewniczakActivities other than copying, distribution and modification are not
73*2587624eSSzymon Olewniczakcovered by this License; they are outside its scope.  The act of
74*2587624eSSzymon Olewniczakrunning the Program is not restricted, and the output from the Program
75*2587624eSSzymon Olewniczakis covered only if its contents constitute a work based on the
76*2587624eSSzymon OlewniczakProgram (independent of having been made by running the Program).
77*2587624eSSzymon OlewniczakWhether that is true depends on what the Program does.
78*2587624eSSzymon Olewniczak
79*2587624eSSzymon Olewniczak  1. You may copy and distribute verbatim copies of the Program's
80*2587624eSSzymon Olewniczaksource code as you receive it, in any medium, provided that you
81*2587624eSSzymon Olewniczakconspicuously and appropriately publish on each copy an appropriate
82*2587624eSSzymon Olewniczakcopyright notice and disclaimer of warranty; keep intact all the
83*2587624eSSzymon Olewniczaknotices that refer to this License and to the absence of any warranty;
84*2587624eSSzymon Olewniczakand give any other recipients of the Program a copy of this License
85*2587624eSSzymon Olewniczakalong with the Program.
86*2587624eSSzymon Olewniczak
87*2587624eSSzymon OlewniczakYou may charge a fee for the physical act of transferring a copy, and
88*2587624eSSzymon Olewniczakyou may at your option offer warranty protection in exchange for a fee.
89*2587624eSSzymon Olewniczak
90*2587624eSSzymon Olewniczak  2. You may modify your copy or copies of the Program or any portion
91*2587624eSSzymon Olewniczakof it, thus forming a work based on the Program, and copy and
92*2587624eSSzymon Olewniczakdistribute such modifications or work under the terms of Section 1
93*2587624eSSzymon Olewniczakabove, provided that you also meet all of these conditions:
94*2587624eSSzymon Olewniczak
95*2587624eSSzymon Olewniczak    a) You must cause the modified files to carry prominent notices
96*2587624eSSzymon Olewniczak    stating that you changed the files and the date of any change.
97*2587624eSSzymon Olewniczak
98*2587624eSSzymon Olewniczak    b) You must cause any work that you distribute or publish, that in
99*2587624eSSzymon Olewniczak    whole or in part contains or is derived from the Program or any
100*2587624eSSzymon Olewniczak    part thereof, to be licensed as a whole at no charge to all third
101*2587624eSSzymon Olewniczak    parties under the terms of this License.
102*2587624eSSzymon Olewniczak
103*2587624eSSzymon Olewniczak    c) If the modified program normally reads commands interactively
104*2587624eSSzymon Olewniczak    when run, you must cause it, when started running for such
105*2587624eSSzymon Olewniczak    interactive use in the most ordinary way, to print or display an
106*2587624eSSzymon Olewniczak    announcement including an appropriate copyright notice and a
107*2587624eSSzymon Olewniczak    notice that there is no warranty (or else, saying that you provide
108*2587624eSSzymon Olewniczak    a warranty) and that users may redistribute the program under
109*2587624eSSzymon Olewniczak    these conditions, and telling the user how to view a copy of this
110*2587624eSSzymon Olewniczak    License.  (Exception: if the Program itself is interactive but
111*2587624eSSzymon Olewniczak    does not normally print such an announcement, your work based on
112*2587624eSSzymon Olewniczak    the Program is not required to print an announcement.)
113*2587624eSSzymon Olewniczak
114*2587624eSSzymon OlewniczakThese requirements apply to the modified work as a whole.  If
115*2587624eSSzymon Olewniczakidentifiable sections of that work are not derived from the Program,
116*2587624eSSzymon Olewniczakand can be reasonably considered independent and separate works in
117*2587624eSSzymon Olewniczakthemselves, then this License, and its terms, do not apply to those
118*2587624eSSzymon Olewniczaksections when you distribute them as separate works.  But when you
119*2587624eSSzymon Olewniczakdistribute the same sections as part of a whole which is a work based
120*2587624eSSzymon Olewniczakon the Program, the distribution of the whole must be on the terms of
121*2587624eSSzymon Olewniczakthis License, whose permissions for other licensees extend to the
122*2587624eSSzymon Olewniczakentire whole, and thus to each and every part regardless of who wrote it.
123*2587624eSSzymon Olewniczak
124*2587624eSSzymon OlewniczakThus, it is not the intent of this section to claim rights or contest
125*2587624eSSzymon Olewniczakyour rights to work written entirely by you; rather, the intent is to
126*2587624eSSzymon Olewniczakexercise the right to control the distribution of derivative or
127*2587624eSSzymon Olewniczakcollective works based on the Program.
128*2587624eSSzymon Olewniczak
129*2587624eSSzymon OlewniczakIn addition, mere aggregation of another work not based on the Program
130*2587624eSSzymon Olewniczakwith the Program (or with a work based on the Program) on a volume of
131*2587624eSSzymon Olewniczaka storage or distribution medium does not bring the other work under
132*2587624eSSzymon Olewniczakthe scope of this License.
133*2587624eSSzymon Olewniczak
134*2587624eSSzymon Olewniczak  3. You may copy and distribute the Program (or a work based on it,
135*2587624eSSzymon Olewniczakunder Section 2) in object code or executable form under the terms of
136*2587624eSSzymon OlewniczakSections 1 and 2 above provided that you also do one of the following:
137*2587624eSSzymon Olewniczak
138*2587624eSSzymon Olewniczak    a) Accompany it with the complete corresponding machine-readable
139*2587624eSSzymon Olewniczak    source code, which must be distributed under the terms of Sections
140*2587624eSSzymon Olewniczak    1 and 2 above on a medium customarily used for software interchange; or,
141*2587624eSSzymon Olewniczak
142*2587624eSSzymon Olewniczak    b) Accompany it with a written offer, valid for at least three
143*2587624eSSzymon Olewniczak    years, to give any third party, for a charge no more than your
144*2587624eSSzymon Olewniczak    cost of physically performing source distribution, a complete
145*2587624eSSzymon Olewniczak    machine-readable copy of the corresponding source code, to be
146*2587624eSSzymon Olewniczak    distributed under the terms of Sections 1 and 2 above on a medium
147*2587624eSSzymon Olewniczak    customarily used for software interchange; or,
148*2587624eSSzymon Olewniczak
149*2587624eSSzymon Olewniczak    c) Accompany it with the information you received as to the offer
150*2587624eSSzymon Olewniczak    to distribute corresponding source code.  (This alternative is
151*2587624eSSzymon Olewniczak    allowed only for noncommercial distribution and only if you
152*2587624eSSzymon Olewniczak    received the program in object code or executable form with such
153*2587624eSSzymon Olewniczak    an offer, in accord with Subsection b above.)
154*2587624eSSzymon Olewniczak
155*2587624eSSzymon OlewniczakThe source code for a work means the preferred form of the work for
156*2587624eSSzymon Olewniczakmaking modifications to it.  For an executable work, complete source
157*2587624eSSzymon Olewniczakcode means all the source code for all modules it contains, plus any
158*2587624eSSzymon Olewniczakassociated interface definition files, plus the scripts used to
159*2587624eSSzymon Olewniczakcontrol compilation and installation of the executable.  However, as a
160*2587624eSSzymon Olewniczakspecial exception, the source code distributed need not include
161*2587624eSSzymon Olewniczakanything that is normally distributed (in either source or binary
162*2587624eSSzymon Olewniczakform) with the major components (compiler, kernel, and so on) of the
163*2587624eSSzymon Olewniczakoperating system on which the executable runs, unless that component
164*2587624eSSzymon Olewniczakitself accompanies the executable.
165*2587624eSSzymon Olewniczak
166*2587624eSSzymon OlewniczakIf distribution of executable or object code is made by offering
167*2587624eSSzymon Olewniczakaccess to copy from a designated place, then offering equivalent
168*2587624eSSzymon Olewniczakaccess to copy the source code from the same place counts as
169*2587624eSSzymon Olewniczakdistribution of the source code, even though third parties are not
170*2587624eSSzymon Olewniczakcompelled to copy the source along with the object code.
171*2587624eSSzymon Olewniczak
172*2587624eSSzymon Olewniczak  4. You may not copy, modify, sublicense, or distribute the Program
173*2587624eSSzymon Olewniczakexcept as expressly provided under this License.  Any attempt
174*2587624eSSzymon Olewniczakotherwise to copy, modify, sublicense or distribute the Program is
175*2587624eSSzymon Olewniczakvoid, and will automatically terminate your rights under this License.
176*2587624eSSzymon OlewniczakHowever, parties who have received copies, or rights, from you under
177*2587624eSSzymon Olewniczakthis License will not have their licenses terminated so long as such
178*2587624eSSzymon Olewniczakparties remain in full compliance.
179*2587624eSSzymon Olewniczak
180*2587624eSSzymon Olewniczak  5. You are not required to accept this License, since you have not
181*2587624eSSzymon Olewniczaksigned it.  However, nothing else grants you permission to modify or
182*2587624eSSzymon Olewniczakdistribute the Program or its derivative works.  These actions are
183*2587624eSSzymon Olewniczakprohibited by law if you do not accept this License.  Therefore, by
184*2587624eSSzymon Olewniczakmodifying or distributing the Program (or any work based on the
185*2587624eSSzymon OlewniczakProgram), you indicate your acceptance of this License to do so, and
186*2587624eSSzymon Olewniczakall its terms and conditions for copying, distributing or modifying
187*2587624eSSzymon Olewniczakthe Program or works based on it.
188*2587624eSSzymon Olewniczak
189*2587624eSSzymon Olewniczak  6. Each time you redistribute the Program (or any work based on the
190*2587624eSSzymon OlewniczakProgram), the recipient automatically receives a license from the
191*2587624eSSzymon Olewniczakoriginal licensor to copy, distribute or modify the Program subject to
192*2587624eSSzymon Olewniczakthese terms and conditions.  You may not impose any further
193*2587624eSSzymon Olewniczakrestrictions on the recipients' exercise of the rights granted herein.
194*2587624eSSzymon OlewniczakYou are not responsible for enforcing compliance by third parties to
195*2587624eSSzymon Olewniczakthis License.
196*2587624eSSzymon Olewniczak
197*2587624eSSzymon Olewniczak  7. If, as a consequence of a court judgment or allegation of patent
198*2587624eSSzymon Olewniczakinfringement or for any other reason (not limited to patent issues),
199*2587624eSSzymon Olewniczakconditions are imposed on you (whether by court order, agreement or
200*2587624eSSzymon Olewniczakotherwise) that contradict the conditions of this License, they do not
201*2587624eSSzymon Olewniczakexcuse you from the conditions of this License.  If you cannot
202*2587624eSSzymon Olewniczakdistribute so as to satisfy simultaneously your obligations under this
203*2587624eSSzymon OlewniczakLicense and any other pertinent obligations, then as a consequence you
204*2587624eSSzymon Olewniczakmay not distribute the Program at all.  For example, if a patent
205*2587624eSSzymon Olewniczaklicense would not permit royalty-free redistribution of the Program by
206*2587624eSSzymon Olewniczakall those who receive copies directly or indirectly through you, then
207*2587624eSSzymon Olewniczakthe only way you could satisfy both it and this License would be to
208*2587624eSSzymon Olewniczakrefrain entirely from distribution of the Program.
209*2587624eSSzymon Olewniczak
210*2587624eSSzymon OlewniczakIf any portion of this section is held invalid or unenforceable under
211*2587624eSSzymon Olewniczakany particular circumstance, the balance of the section is intended to
212*2587624eSSzymon Olewniczakapply and the section as a whole is intended to apply in other
213*2587624eSSzymon Olewniczakcircumstances.
214*2587624eSSzymon Olewniczak
215*2587624eSSzymon OlewniczakIt is not the purpose of this section to induce you to infringe any
216*2587624eSSzymon Olewniczakpatents or other property right claims or to contest validity of any
217*2587624eSSzymon Olewniczaksuch claims; this section has the sole purpose of protecting the
218*2587624eSSzymon Olewniczakintegrity of the free software distribution system, which is
219*2587624eSSzymon Olewniczakimplemented by public license practices.  Many people have made
220*2587624eSSzymon Olewniczakgenerous contributions to the wide range of software distributed
221*2587624eSSzymon Olewniczakthrough that system in reliance on consistent application of that
222*2587624eSSzymon Olewniczaksystem; it is up to the author/donor to decide if he or she is willing
223*2587624eSSzymon Olewniczakto distribute software through any other system and a licensee cannot
224*2587624eSSzymon Olewniczakimpose that choice.
225*2587624eSSzymon Olewniczak
226*2587624eSSzymon OlewniczakThis section is intended to make thoroughly clear what is believed to
227*2587624eSSzymon Olewniczakbe a consequence of the rest of this License.
228*2587624eSSzymon Olewniczak
229*2587624eSSzymon Olewniczak  8. If the distribution and/or use of the Program is restricted in
230*2587624eSSzymon Olewniczakcertain countries either by patents or by copyrighted interfaces, the
231*2587624eSSzymon Olewniczakoriginal copyright holder who places the Program under this License
232*2587624eSSzymon Olewniczakmay add an explicit geographical distribution limitation excluding
233*2587624eSSzymon Olewniczakthose countries, so that distribution is permitted only in or among
234*2587624eSSzymon Olewniczakcountries not thus excluded.  In such case, this License incorporates
235*2587624eSSzymon Olewniczakthe limitation as if written in the body of this License.
236*2587624eSSzymon Olewniczak
237*2587624eSSzymon Olewniczak  9. The Free Software Foundation may publish revised and/or new versions
238*2587624eSSzymon Olewniczakof the General Public License from time to time.  Such new versions will
239*2587624eSSzymon Olewniczakbe similar in spirit to the present version, but may differ in detail to
240*2587624eSSzymon Olewniczakaddress new problems or concerns.
241*2587624eSSzymon Olewniczak
242*2587624eSSzymon OlewniczakEach version is given a distinguishing version number.  If the Program
243*2587624eSSzymon Olewniczakspecifies a version number of this License which applies to it and "any
244*2587624eSSzymon Olewniczaklater version", you have the option of following the terms and conditions
245*2587624eSSzymon Olewniczakeither of that version or of any later version published by the Free
246*2587624eSSzymon OlewniczakSoftware Foundation.  If the Program does not specify a version number of

282*2587624eSSzymon Olewniczak            How to Apply These Terms to Your New Programs
283*2587624eSSzymon Olewniczak
284*2587624eSSzymon Olewniczak  If you develop a new program, and you want it to be of the greatest
285*2587624eSSzymon Olewniczakpossible use to the public, the best way to achieve this is to make it
286*2587624eSSzymon Olewniczakfree software which everyone can redistribute and change under these terms.
287*2587624eSSzymon Olewniczak
288*2587624eSSzymon Olewniczak  To do so, attach the following notices to the program.  It is safest
289*2587624eSSzymon Olewniczakto attach them to the start of each source file to most effectively
290*2587624eSSzymon Olewniczakconvey the exclusion of warranty; and each file should have at least
291*2587624eSSzymon Olewniczakthe "copyright" line and a pointer to where the full notice is found.
292*2587624eSSzymon Olewniczak

307*2587624eSSzymon Olewniczak    with this program; if not, write to the Free Software Foundation, Inc.,

310*2587624eSSzymon OlewniczakAlso add information on how to contact you by electronic and paper mail.
311*2587624eSSzymon Olewniczak
312*2587624eSSzymon OlewniczakIf the program is interactive, make it output a short notice like this
313*2587624eSSzymon Olewniczakwhen it starts in an interactive mode:
314*2587624eSSzymon Olewniczak
315*2587624eSSzymon Olewniczak    Gnomovision version 69, Copyright (C) year name of author
316*2587624eSSzymon Olewniczak    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
317*2587624eSSzymon Olewniczak    This is free software, and you are welcome to redistribute it
318*2587624eSSzymon Olewniczak    under certain conditions; type `show c' for details.
319*2587624eSSzymon Olewniczak
320*2587624eSSzymon OlewniczakThe hypothetical commands `show w' and `show c' should show the appropriate
321*2587624eSSzymon Olewniczakparts of the General Public License.  Of course, the commands you use may
322*2587624eSSzymon Olewniczakbe called something other than `show w' and `show c'; they could even be
323*2587624eSSzymon Olewniczakmouse-clicks or menu items--whatever suits your program.
324*2587624eSSzymon Olewniczak
325*2587624eSSzymon OlewniczakYou should also get your employer (if you work as a programmer) or your
326*2587624eSSzymon Olewniczakschool, if any, to sign a "copyright disclaimer" for the program, if
327*2587624eSSzymon Olewniczaknecessary.  Here is a sample; alter the names:

335*2587624eSSzymon OlewniczakThis General Public License does not permit incorporating your program into
336*2587624eSSzymon Olewniczakproprietary programs.  If your program is a subroutine library, you may
337*2587624eSSzymon Olewniczakconsider it more useful to permit linking proprietary applications with the
