6*c526b210SAnna Dabrowska Everyone is permitted to copy and distribute verbatim copies
7*c526b210SAnna Dabrowska of this license document, but changing it is not allowed.
8*c526b210SAnna Dabrowska
9*c526b210SAnna Dabrowska                            Preamble
10*c526b210SAnna Dabrowska
11*c526b210SAnna Dabrowska  The licenses for most software are designed to take away your
12*c526b210SAnna Dabrowskafreedom to share and change it.  By contrast, the GNU General Public
13*c526b210SAnna DabrowskaLicense is intended to guarantee your freedom to share and change free
14*c526b210SAnna Dabrowskasoftware--to make sure the software is free for all its users.  This
15*c526b210SAnna DabrowskaGeneral Public License applies to most of the Free Software
16*c526b210SAnna DabrowskaFoundation's software and to any other program whose authors commit to
17*c526b210SAnna Dabrowskausing it.  (Some other Free Software Foundation software is covered by
18*c526b210SAnna Dabrowskathe GNU Lesser General Public License instead.)  You can apply it to
19*c526b210SAnna Dabrowskayour programs, too.
20*c526b210SAnna Dabrowska
21*c526b210SAnna Dabrowska  When we speak of free software, we are referring to freedom, not
22*c526b210SAnna Dabrowskaprice.  Our General Public Licenses are designed to make sure that you
23*c526b210SAnna Dabrowskahave the freedom to distribute copies of free software (and charge for
24*c526b210SAnna Dabrowskathis service if you wish), that you receive source code or can get it
25*c526b210SAnna Dabrowskaif you want it, that you can change the software or use pieces of it
26*c526b210SAnna Dabrowskain new free programs; and that you know you can do these things.
27*c526b210SAnna Dabrowska
28*c526b210SAnna Dabrowska  To protect your rights, we need to make restrictions that forbid
29*c526b210SAnna Dabrowskaanyone to deny you these rights or to ask you to surrender the rights.
30*c526b210SAnna DabrowskaThese restrictions translate to certain responsibilities for you if you
31*c526b210SAnna Dabrowskadistribute copies of the software, or if you modify it.
32*c526b210SAnna Dabrowska
33*c526b210SAnna Dabrowska  For example, if you distribute copies of such a program, whether
34*c526b210SAnna Dabrowskagratis or for a fee, you must give the recipients all the rights that
35*c526b210SAnna Dabrowskayou have.  You must make sure that they, too, receive or can get the
36*c526b210SAnna Dabrowskasource code.  And you must show them these terms so they know their
37*c526b210SAnna Dabrowskarights.
38*c526b210SAnna Dabrowska
39*c526b210SAnna Dabrowska  We protect your rights with two steps: (1) copyright the software, and
40*c526b210SAnna Dabrowska(2) offer you this license which gives you legal permission to copy,
41*c526b210SAnna Dabrowskadistribute and/or modify the software.
42*c526b210SAnna Dabrowska
43*c526b210SAnna Dabrowska  Also, for each author's protection and ours, we want to make certain
44*c526b210SAnna Dabrowskathat everyone understands that there is no warranty for this free
45*c526b210SAnna Dabrowskasoftware.  If the software is modified by someone else and passed on, we
46*c526b210SAnna Dabrowskawant its recipients to know that what they have is not the original, so
47*c526b210SAnna Dabrowskathat any problems introduced by others will not reflect on the original
48*c526b210SAnna Dabrowskaauthors' reputations.
49*c526b210SAnna Dabrowska
50*c526b210SAnna Dabrowska  Finally, any free program is threatened constantly by software
51*c526b210SAnna Dabrowskapatents.  We wish to avoid the danger that redistributors of a free
52*c526b210SAnna Dabrowskaprogram will individually obtain patent licenses, in effect making the
53*c526b210SAnna Dabrowskaprogram proprietary.  To prevent this, we have made it clear that any
54*c526b210SAnna Dabrowskapatent must be licensed for everyone's free use or not licensed at all.
55*c526b210SAnna Dabrowska
56*c526b210SAnna Dabrowska  The precise terms and conditions for copying, distribution and
57*c526b210SAnna Dabrowskamodification follow.
58*c526b210SAnna Dabrowska
59*c526b210SAnna Dabrowska                    GNU GENERAL PUBLIC LICENSE
60*c526b210SAnna Dabrowska   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
61*c526b210SAnna Dabrowska
62*c526b210SAnna Dabrowska  0. This License applies to any program or other work which contains
63*c526b210SAnna Dabrowskaa notice placed by the copyright holder saying it may be distributed
64*c526b210SAnna Dabrowskaunder the terms of this General Public License.  The "Program", below,
65*c526b210SAnna Dabrowskarefers to any such program or work, and a "work based on the Program"
66*c526b210SAnna Dabrowskameans either the Program or any derivative work under copyright law:
67*c526b210SAnna Dabrowskathat is to say, a work containing the Program or a portion of it,
68*c526b210SAnna Dabrowskaeither verbatim or with modifications and/or translated into another
69*c526b210SAnna Dabrowskalanguage.  (Hereinafter, translation is included without limitation in
70*c526b210SAnna Dabrowskathe term "modification".)  Each licensee is addressed as "you".
71*c526b210SAnna Dabrowska
72*c526b210SAnna DabrowskaActivities other than copying, distribution and modification are not
73*c526b210SAnna Dabrowskacovered by this License; they are outside its scope.  The act of
74*c526b210SAnna Dabrowskarunning the Program is not restricted, and the output from the Program
75*c526b210SAnna Dabrowskais covered only if its contents constitute a work based on the
76*c526b210SAnna DabrowskaProgram (independent of having been made by running the Program).
77*c526b210SAnna DabrowskaWhether that is true depends on what the Program does.
78*c526b210SAnna Dabrowska
79*c526b210SAnna Dabrowska  1. You may copy and distribute verbatim copies of the Program's
80*c526b210SAnna Dabrowskasource code as you receive it, in any medium, provided that you
81*c526b210SAnna Dabrowskaconspicuously and appropriately publish on each copy an appropriate
82*c526b210SAnna Dabrowskacopyright notice and disclaimer of warranty; keep intact all the
83*c526b210SAnna Dabrowskanotices that refer to this License and to the absence of any warranty;
84*c526b210SAnna Dabrowskaand give any other recipients of the Program a copy of this License
85*c526b210SAnna Dabrowskaalong with the Program.
86*c526b210SAnna Dabrowska
87*c526b210SAnna DabrowskaYou may charge a fee for the physical act of transferring a copy, and
88*c526b210SAnna Dabrowskayou may at your option offer warranty protection in exchange for a fee.
89*c526b210SAnna Dabrowska
90*c526b210SAnna Dabrowska  2. You may modify your copy or copies of the Program or any portion
91*c526b210SAnna Dabrowskaof it, thus forming a work based on the Program, and copy and
92*c526b210SAnna Dabrowskadistribute such modifications or work under the terms of Section 1
93*c526b210SAnna Dabrowskaabove, provided that you also meet all of these conditions:
94*c526b210SAnna Dabrowska
95*c526b210SAnna Dabrowska    a) You must cause the modified files to carry prominent notices
96*c526b210SAnna Dabrowska    stating that you changed the files and the date of any change.
97*c526b210SAnna Dabrowska
98*c526b210SAnna Dabrowska    b) You must cause any work that you distribute or publish, that in
99*c526b210SAnna Dabrowska    whole or in part contains or is derived from the Program or any
100*c526b210SAnna Dabrowska    part thereof, to be licensed as a whole at no charge to all third
101*c526b210SAnna Dabrowska    parties under the terms of this License.
102*c526b210SAnna Dabrowska
103*c526b210SAnna Dabrowska    c) If the modified program normally reads commands interactively
104*c526b210SAnna Dabrowska    when run, you must cause it, when started running for such
105*c526b210SAnna Dabrowska    interactive use in the most ordinary way, to print or display an
106*c526b210SAnna Dabrowska    announcement including an appropriate copyright notice and a
107*c526b210SAnna Dabrowska    notice that there is no warranty (or else, saying that you provide
108*c526b210SAnna Dabrowska    a warranty) and that users may redistribute the program under
109*c526b210SAnna Dabrowska    these conditions, and telling the user how to view a copy of this
110*c526b210SAnna Dabrowska    License.  (Exception: if the Program itself is interactive but
111*c526b210SAnna Dabrowska    does not normally print such an announcement, your work based on
112*c526b210SAnna Dabrowska    the Program is not required to print an announcement.)
113*c526b210SAnna Dabrowska
114*c526b210SAnna DabrowskaThese requirements apply to the modified work as a whole.  If
115*c526b210SAnna Dabrowskaidentifiable sections of that work are not derived from the Program,
116*c526b210SAnna Dabrowskaand can be reasonably considered independent and separate works in
117*c526b210SAnna Dabrowskathemselves, then this License, and its terms, do not apply to those
118*c526b210SAnna Dabrowskasections when you distribute them as separate works.  But when you
119*c526b210SAnna Dabrowskadistribute the same sections as part of a whole which is a work based
120*c526b210SAnna Dabrowskaon the Program, the distribution of the whole must be on the terms of
121*c526b210SAnna Dabrowskathis License, whose permissions for other licensees extend to the
122*c526b210SAnna Dabrowskaentire whole, and thus to each and every part regardless of who wrote it.
123*c526b210SAnna Dabrowska
124*c526b210SAnna DabrowskaThus, it is not the intent of this section to claim rights or contest
125*c526b210SAnna Dabrowskayour rights to work written entirely by you; rather, the intent is to
126*c526b210SAnna Dabrowskaexercise the right to control the distribution of derivative or
127*c526b210SAnna Dabrowskacollective works based on the Program.
128*c526b210SAnna Dabrowska
129*c526b210SAnna DabrowskaIn addition, mere aggregation of another work not based on the Program
130*c526b210SAnna Dabrowskawith the Program (or with a work based on the Program) on a volume of
131*c526b210SAnna Dabrowskaa storage or distribution medium does not bring the other work under
132*c526b210SAnna Dabrowskathe scope of this License.
133*c526b210SAnna Dabrowska
134*c526b210SAnna Dabrowska  3. You may copy and distribute the Program (or a work based on it,
135*c526b210SAnna Dabrowskaunder Section 2) in object code or executable form under the terms of
136*c526b210SAnna DabrowskaSections 1 and 2 above provided that you also do one of the following:
137*c526b210SAnna Dabrowska
138*c526b210SAnna Dabrowska    a) Accompany it with the complete corresponding machine-readable
139*c526b210SAnna Dabrowska    source code, which must be distributed under the terms of Sections
140*c526b210SAnna Dabrowska    1 and 2 above on a medium customarily used for software interchange; or,
141*c526b210SAnna Dabrowska
142*c526b210SAnna Dabrowska    b) Accompany it with a written offer, valid for at least three
143*c526b210SAnna Dabrowska    years, to give any third party, for a charge no more than your
144*c526b210SAnna Dabrowska    cost of physically performing source distribution, a complete
145*c526b210SAnna Dabrowska    machine-readable copy of the corresponding source code, to be
146*c526b210SAnna Dabrowska    distributed under the terms of Sections 1 and 2 above on a medium
147*c526b210SAnna Dabrowska    customarily used for software interchange; or,
148*c526b210SAnna Dabrowska
149*c526b210SAnna Dabrowska    c) Accompany it with the information you received as to the offer
150*c526b210SAnna Dabrowska    to distribute corresponding source code.  (This alternative is
151*c526b210SAnna Dabrowska    allowed only for noncommercial distribution and only if you
152*c526b210SAnna Dabrowska    received the program in object code or executable form with such
153*c526b210SAnna Dabrowska    an offer, in accord with Subsection b above.)
154*c526b210SAnna Dabrowska
155*c526b210SAnna DabrowskaThe source code for a work means the preferred form of the work for
156*c526b210SAnna Dabrowskamaking modifications to it.  For an executable work, complete source
157*c526b210SAnna Dabrowskacode means all the source code for all modules it contains, plus any
158*c526b210SAnna Dabrowskaassociated interface definition files, plus the scripts used to
159*c526b210SAnna Dabrowskacontrol compilation and installation of the executable.  However, as a
160*c526b210SAnna Dabrowskaspecial exception, the source code distributed need not include
161*c526b210SAnna Dabrowskaanything that is normally distributed (in either source or binary
162*c526b210SAnna Dabrowskaform) with the major components (compiler, kernel, and so on) of the
163*c526b210SAnna Dabrowskaoperating system on which the executable runs, unless that component
164*c526b210SAnna Dabrowskaitself accompanies the executable.
165*c526b210SAnna Dabrowska
166*c526b210SAnna DabrowskaIf distribution of executable or object code is made by offering
167*c526b210SAnna Dabrowskaaccess to copy from a designated place, then offering equivalent
168*c526b210SAnna Dabrowskaaccess to copy the source code from the same place counts as
169*c526b210SAnna Dabrowskadistribution of the source code, even though third parties are not
170*c526b210SAnna Dabrowskacompelled to copy the source along with the object code.
171*c526b210SAnna Dabrowska
172*c526b210SAnna Dabrowska  4. You may not copy, modify, sublicense, or distribute the Program
173*c526b210SAnna Dabrowskaexcept as expressly provided under this License.  Any attempt
174*c526b210SAnna Dabrowskaotherwise to copy, modify, sublicense or distribute the Program is
175*c526b210SAnna Dabrowskavoid, and will automatically terminate your rights under this License.
176*c526b210SAnna DabrowskaHowever, parties who have received copies, or rights, from you under
177*c526b210SAnna Dabrowskathis License will not have their licenses terminated so long as such
178*c526b210SAnna Dabrowskaparties remain in full compliance.
179*c526b210SAnna Dabrowska
180*c526b210SAnna Dabrowska  5. You are not required to accept this License, since you have not
181*c526b210SAnna Dabrowskasigned it.  However, nothing else grants you permission to modify or
182*c526b210SAnna Dabrowskadistribute the Program or its derivative works.  These actions are
183*c526b210SAnna Dabrowskaprohibited by law if you do not accept this License.  Therefore, by
184*c526b210SAnna Dabrowskamodifying or distributing the Program (or any work based on the
185*c526b210SAnna DabrowskaProgram), you indicate your acceptance of this License to do so, and
186*c526b210SAnna Dabrowskaall its terms and conditions for copying, distributing or modifying
187*c526b210SAnna Dabrowskathe Program or works based on it.
188*c526b210SAnna Dabrowska
189*c526b210SAnna Dabrowska  6. Each time you redistribute the Program (or any work based on the
190*c526b210SAnna DabrowskaProgram), the recipient automatically receives a license from the
191*c526b210SAnna Dabrowskaoriginal licensor to copy, distribute or modify the Program subject to
192*c526b210SAnna Dabrowskathese terms and conditions.  You may not impose any further
193*c526b210SAnna Dabrowskarestrictions on the recipients' exercise of the rights granted herein.
194*c526b210SAnna DabrowskaYou are not responsible for enforcing compliance by third parties to
195*c526b210SAnna Dabrowskathis License.
196*c526b210SAnna Dabrowska
197*c526b210SAnna Dabrowska  7. If, as a consequence of a court judgment or allegation of patent
198*c526b210SAnna Dabrowskainfringement or for any other reason (not limited to patent issues),
199*c526b210SAnna Dabrowskaconditions are imposed on you (whether by court order, agreement or
200*c526b210SAnna Dabrowskaotherwise) that contradict the conditions of this License, they do not
201*c526b210SAnna Dabrowskaexcuse you from the conditions of this License.  If you cannot
202*c526b210SAnna Dabrowskadistribute so as to satisfy simultaneously your obligations under this
203*c526b210SAnna DabrowskaLicense and any other pertinent obligations, then as a consequence you
204*c526b210SAnna Dabrowskamay not distribute the Program at all.  For example, if a patent
205*c526b210SAnna Dabrowskalicense would not permit royalty-free redistribution of the Program by
206*c526b210SAnna Dabrowskaall those who receive copies directly or indirectly through you, then
207*c526b210SAnna Dabrowskathe only way you could satisfy both it and this License would be to
208*c526b210SAnna Dabrowskarefrain entirely from distribution of the Program.
209*c526b210SAnna Dabrowska
210*c526b210SAnna DabrowskaIf any portion of this section is held invalid or unenforceable under
211*c526b210SAnna Dabrowskaany particular circumstance, the balance of the section is intended to
212*c526b210SAnna Dabrowskaapply and the section as a whole is intended to apply in other
213*c526b210SAnna Dabrowskacircumstances.
214*c526b210SAnna Dabrowska
215*c526b210SAnna DabrowskaIt is not the purpose of this section to induce you to infringe any
216*c526b210SAnna Dabrowskapatents or other property right claims or to contest validity of any
217*c526b210SAnna Dabrowskasuch claims; this section has the sole purpose of protecting the
218*c526b210SAnna Dabrowskaintegrity of the free software distribution system, which is
219*c526b210SAnna Dabrowskaimplemented by public license practices.  Many people have made
220*c526b210SAnna Dabrowskagenerous contributions to the wide range of software distributed
221*c526b210SAnna Dabrowskathrough that system in reliance on consistent application of that
222*c526b210SAnna Dabrowskasystem; it is up to the author/donor to decide if he or she is willing
223*c526b210SAnna Dabrowskato distribute software through any other system and a licensee cannot
224*c526b210SAnna Dabrowskaimpose that choice.
225*c526b210SAnna Dabrowska
226*c526b210SAnna DabrowskaThis section is intended to make thoroughly clear what is believed to
227*c526b210SAnna Dabrowskabe a consequence of the rest of this License.
228*c526b210SAnna Dabrowska
229*c526b210SAnna Dabrowska  8. If the distribution and/or use of the Program is restricted in
230*c526b210SAnna Dabrowskacertain countries either by patents or by copyrighted interfaces, the
231*c526b210SAnna Dabrowskaoriginal copyright holder who places the Program under this License
232*c526b210SAnna Dabrowskamay add an explicit geographical distribution limitation excluding
233*c526b210SAnna Dabrowskathose countries, so that distribution is permitted only in or among
234*c526b210SAnna Dabrowskacountries not thus excluded.  In such case, this License incorporates
235*c526b210SAnna Dabrowskathe limitation as if written in the body of this License.
236*c526b210SAnna Dabrowska
237*c526b210SAnna Dabrowska  9. The Free Software Foundation may publish revised and/or new versions
238*c526b210SAnna Dabrowskaof the General Public License from time to time.  Such new versions will
239*c526b210SAnna Dabrowskabe similar in spirit to the present version, but may differ in detail to
240*c526b210SAnna Dabrowskaaddress new problems or concerns.
241*c526b210SAnna Dabrowska
242*c526b210SAnna DabrowskaEach version is given a distinguishing version number.  If the Program
243*c526b210SAnna Dabrowskaspecifies a version number of this License which applies to it and "any
244*c526b210SAnna Dabrowskalater version", you have the option of following the terms and conditions
245*c526b210SAnna Dabrowskaeither of that version or of any later version published by the Free
246*c526b210SAnna DabrowskaSoftware Foundation.  If the Program does not specify a version number of
247*c526b210SAnna Dabrowskathis License, you may choose any version ever published by the Free Software
248*c526b210SAnna DabrowskaFoundation.
249*c526b210SAnna Dabrowska
250*c526b210SAnna Dabrowska  10. If you wish to incorporate parts of the Program into other free
251*c526b210SAnna Dabrowskaprograms whose distribution conditions are different, write to the author
252*c526b210SAnna Dabrowskato ask for permission.  For software which is copyrighted by the Free
253*c526b210SAnna DabrowskaSoftware Foundation, write to the Free Software Foundation; we sometimes
254*c526b210SAnna Dabrowskamake exceptions for this.  Our decision will be guided by the two goals
255*c526b210SAnna Dabrowskaof preserving the free status of all derivatives of our free software and
256*c526b210SAnna Dabrowskaof promoting the sharing and reuse of software generally.
257*c526b210SAnna Dabrowska
258*c526b210SAnna Dabrowska                            NO WARRANTY
259*c526b210SAnna Dabrowska
260*c526b210SAnna Dabrowska  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
