6*5bfd2b37SAndreas Gohr Everyone is permitted to copy and distribute verbatim copies
7*5bfd2b37SAndreas Gohr of this license document, but changing it is not allowed.
8*5bfd2b37SAndreas Gohr
9*5bfd2b37SAndreas Gohr                            Preamble
10*5bfd2b37SAndreas Gohr
11*5bfd2b37SAndreas Gohr  The licenses for most software are designed to take away your
12*5bfd2b37SAndreas Gohrfreedom to share and change it.  By contrast, the GNU General Public
13*5bfd2b37SAndreas GohrLicense is intended to guarantee your freedom to share and change free
14*5bfd2b37SAndreas Gohrsoftware--to make sure the software is free for all its users.  This
15*5bfd2b37SAndreas GohrGeneral Public License applies to most of the Free Software
16*5bfd2b37SAndreas GohrFoundation's software and to any other program whose authors commit to
17*5bfd2b37SAndreas Gohrusing it.  (Some other Free Software Foundation software is covered by
18*5bfd2b37SAndreas Gohrthe GNU Lesser General Public License instead.)  You can apply it to
19*5bfd2b37SAndreas Gohryour programs, too.
20*5bfd2b37SAndreas Gohr
21*5bfd2b37SAndreas Gohr  When we speak of free software, we are referring to freedom, not
22*5bfd2b37SAndreas Gohrprice.  Our General Public Licenses are designed to make sure that you
23*5bfd2b37SAndreas Gohrhave the freedom to distribute copies of free software (and charge for
24*5bfd2b37SAndreas Gohrthis service if you wish), that you receive source code or can get it
25*5bfd2b37SAndreas Gohrif you want it, that you can change the software or use pieces of it
26*5bfd2b37SAndreas Gohrin new free programs; and that you know you can do these things.
27*5bfd2b37SAndreas Gohr
28*5bfd2b37SAndreas Gohr  To protect your rights, we need to make restrictions that forbid
29*5bfd2b37SAndreas Gohranyone to deny you these rights or to ask you to surrender the rights.
30*5bfd2b37SAndreas GohrThese restrictions translate to certain responsibilities for you if you
31*5bfd2b37SAndreas Gohrdistribute copies of the software, or if you modify it.
32*5bfd2b37SAndreas Gohr
33*5bfd2b37SAndreas Gohr  For example, if you distribute copies of such a program, whether
34*5bfd2b37SAndreas Gohrgratis or for a fee, you must give the recipients all the rights that
35*5bfd2b37SAndreas Gohryou have.  You must make sure that they, too, receive or can get the
36*5bfd2b37SAndreas Gohrsource code.  And you must show them these terms so they know their
37*5bfd2b37SAndreas Gohrrights.
38*5bfd2b37SAndreas Gohr
39*5bfd2b37SAndreas Gohr  We protect your rights with two steps: (1) copyright the software, and
40*5bfd2b37SAndreas Gohr(2) offer you this license which gives you legal permission to copy,
41*5bfd2b37SAndreas Gohrdistribute and/or modify the software.
42*5bfd2b37SAndreas Gohr
43*5bfd2b37SAndreas Gohr  Also, for each author's protection and ours, we want to make certain
44*5bfd2b37SAndreas Gohrthat everyone understands that there is no warranty for this free
45*5bfd2b37SAndreas Gohrsoftware.  If the software is modified by someone else and passed on, we
46*5bfd2b37SAndreas Gohrwant its recipients to know that what they have is not the original, so
47*5bfd2b37SAndreas Gohrthat any problems introduced by others will not reflect on the original
48*5bfd2b37SAndreas Gohrauthors' reputations.
49*5bfd2b37SAndreas Gohr
50*5bfd2b37SAndreas Gohr  Finally, any free program is threatened constantly by software
51*5bfd2b37SAndreas Gohrpatents.  We wish to avoid the danger that redistributors of a free
52*5bfd2b37SAndreas Gohrprogram will individually obtain patent licenses, in effect making the
53*5bfd2b37SAndreas Gohrprogram proprietary.  To prevent this, we have made it clear that any
54*5bfd2b37SAndreas Gohrpatent must be licensed for everyone's free use or not licensed at all.
55*5bfd2b37SAndreas Gohr
56*5bfd2b37SAndreas Gohr  The precise terms and conditions for copying, distribution and
57*5bfd2b37SAndreas Gohrmodification follow.
58*5bfd2b37SAndreas Gohr
59*5bfd2b37SAndreas Gohr                    GNU GENERAL PUBLIC LICENSE
60*5bfd2b37SAndreas Gohr   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
61*5bfd2b37SAndreas Gohr
62*5bfd2b37SAndreas Gohr  0. This License applies to any program or other work which contains
63*5bfd2b37SAndreas Gohra notice placed by the copyright holder saying it may be distributed
64*5bfd2b37SAndreas Gohrunder the terms of this General Public License.  The "Program", below,
65*5bfd2b37SAndreas Gohrrefers to any such program or work, and a "work based on the Program"
66*5bfd2b37SAndreas Gohrmeans either the Program or any derivative work under copyright law:
67*5bfd2b37SAndreas Gohrthat is to say, a work containing the Program or a portion of it,
68*5bfd2b37SAndreas Gohreither verbatim or with modifications and/or translated into another
69*5bfd2b37SAndreas Gohrlanguage.  (Hereinafter, translation is included without limitation in
70*5bfd2b37SAndreas Gohrthe term "modification".)  Each licensee is addressed as "you".
71*5bfd2b37SAndreas Gohr
72*5bfd2b37SAndreas GohrActivities other than copying, distribution and modification are not
73*5bfd2b37SAndreas Gohrcovered by this License; they are outside its scope.  The act of
74*5bfd2b37SAndreas Gohrrunning the Program is not restricted, and the output from the Program
75*5bfd2b37SAndreas Gohris covered only if its contents constitute a work based on the
76*5bfd2b37SAndreas GohrProgram (independent of having been made by running the Program).
77*5bfd2b37SAndreas GohrWhether that is true depends on what the Program does.
78*5bfd2b37SAndreas Gohr
79*5bfd2b37SAndreas Gohr  1. You may copy and distribute verbatim copies of the Program's
80*5bfd2b37SAndreas Gohrsource code as you receive it, in any medium, provided that you
81*5bfd2b37SAndreas Gohrconspicuously and appropriately publish on each copy an appropriate
82*5bfd2b37SAndreas Gohrcopyright notice and disclaimer of warranty; keep intact all the
83*5bfd2b37SAndreas Gohrnotices that refer to this License and to the absence of any warranty;
84*5bfd2b37SAndreas Gohrand give any other recipients of the Program a copy of this License
85*5bfd2b37SAndreas Gohralong with the Program.
86*5bfd2b37SAndreas Gohr
87*5bfd2b37SAndreas GohrYou may charge a fee for the physical act of transferring a copy, and
88*5bfd2b37SAndreas Gohryou may at your option offer warranty protection in exchange for a fee.
89*5bfd2b37SAndreas Gohr
90*5bfd2b37SAndreas Gohr  2. You may modify your copy or copies of the Program or any portion
91*5bfd2b37SAndreas Gohrof it, thus forming a work based on the Program, and copy and
92*5bfd2b37SAndreas Gohrdistribute such modifications or work under the terms of Section 1
93*5bfd2b37SAndreas Gohrabove, provided that you also meet all of these conditions:
94*5bfd2b37SAndreas Gohr
95*5bfd2b37SAndreas Gohr    a) You must cause the modified files to carry prominent notices
96*5bfd2b37SAndreas Gohr    stating that you changed the files and the date of any change.
97*5bfd2b37SAndreas Gohr
98*5bfd2b37SAndreas Gohr    b) You must cause any work that you distribute or publish, that in
99*5bfd2b37SAndreas Gohr    whole or in part contains or is derived from the Program or any
100*5bfd2b37SAndreas Gohr    part thereof, to be licensed as a whole at no charge to all third
101*5bfd2b37SAndreas Gohr    parties under the terms of this License.
102*5bfd2b37SAndreas Gohr
103*5bfd2b37SAndreas Gohr    c) If the modified program normally reads commands interactively
104*5bfd2b37SAndreas Gohr    when run, you must cause it, when started running for such
105*5bfd2b37SAndreas Gohr    interactive use in the most ordinary way, to print or display an
106*5bfd2b37SAndreas Gohr    announcement including an appropriate copyright notice and a
107*5bfd2b37SAndreas Gohr    notice that there is no warranty (or else, saying that you provide
108*5bfd2b37SAndreas Gohr    a warranty) and that users may redistribute the program under
109*5bfd2b37SAndreas Gohr    these conditions, and telling the user how to view a copy of this
110*5bfd2b37SAndreas Gohr    License.  (Exception: if the Program itself is interactive but
111*5bfd2b37SAndreas Gohr    does not normally print such an announcement, your work based on
112*5bfd2b37SAndreas Gohr    the Program is not required to print an announcement.)
113*5bfd2b37SAndreas Gohr
114*5bfd2b37SAndreas GohrThese requirements apply to the modified work as a whole.  If
115*5bfd2b37SAndreas Gohridentifiable sections of that work are not derived from the Program,
116*5bfd2b37SAndreas Gohrand can be reasonably considered independent and separate works in
117*5bfd2b37SAndreas Gohrthemselves, then this License, and its terms, do not apply to those
118*5bfd2b37SAndreas Gohrsections when you distribute them as separate works.  But when you
119*5bfd2b37SAndreas Gohrdistribute the same sections as part of a whole which is a work based
120*5bfd2b37SAndreas Gohron the Program, the distribution of the whole must be on the terms of
121*5bfd2b37SAndreas Gohrthis License, whose permissions for other licensees extend to the
122*5bfd2b37SAndreas Gohrentire whole, and thus to each and every part regardless of who wrote it.
123*5bfd2b37SAndreas Gohr
124*5bfd2b37SAndreas GohrThus, it is not the intent of this section to claim rights or contest
125*5bfd2b37SAndreas Gohryour rights to work written entirely by you; rather, the intent is to
126*5bfd2b37SAndreas Gohrexercise the right to control the distribution of derivative or
127*5bfd2b37SAndreas Gohrcollective works based on the Program.
128*5bfd2b37SAndreas Gohr
129*5bfd2b37SAndreas GohrIn addition, mere aggregation of another work not based on the Program
130*5bfd2b37SAndreas Gohrwith the Program (or with a work based on the Program) on a volume of
131*5bfd2b37SAndreas Gohra storage or distribution medium does not bring the other work under
132*5bfd2b37SAndreas Gohrthe scope of this License.
133*5bfd2b37SAndreas Gohr
134*5bfd2b37SAndreas Gohr  3. You may copy and distribute the Program (or a work based on it,
135*5bfd2b37SAndreas Gohrunder Section 2) in object code or executable form under the terms of
136*5bfd2b37SAndreas GohrSections 1 and 2 above provided that you also do one of the following:
137*5bfd2b37SAndreas Gohr
138*5bfd2b37SAndreas Gohr    a) Accompany it with the complete corresponding machine-readable
139*5bfd2b37SAndreas Gohr    source code, which must be distributed under the terms of Sections
140*5bfd2b37SAndreas Gohr    1 and 2 above on a medium customarily used for software interchange; or,
141*5bfd2b37SAndreas Gohr
142*5bfd2b37SAndreas Gohr    b) Accompany it with a written offer, valid for at least three
143*5bfd2b37SAndreas Gohr    years, to give any third party, for a charge no more than your
144*5bfd2b37SAndreas Gohr    cost of physically performing source distribution, a complete
145*5bfd2b37SAndreas Gohr    machine-readable copy of the corresponding source code, to be
146*5bfd2b37SAndreas Gohr    distributed under the terms of Sections 1 and 2 above on a medium
147*5bfd2b37SAndreas Gohr    customarily used for software interchange; or,
148*5bfd2b37SAndreas Gohr
149*5bfd2b37SAndreas Gohr    c) Accompany it with the information you received as to the offer
150*5bfd2b37SAndreas Gohr    to distribute corresponding source code.  (This alternative is
151*5bfd2b37SAndreas Gohr    allowed only for noncommercial distribution and only if you
152*5bfd2b37SAndreas Gohr    received the program in object code or executable form with such
153*5bfd2b37SAndreas Gohr    an offer, in accord with Subsection b above.)
154*5bfd2b37SAndreas Gohr
155*5bfd2b37SAndreas GohrThe source code for a work means the preferred form of the work for
156*5bfd2b37SAndreas Gohrmaking modifications to it.  For an executable work, complete source
157*5bfd2b37SAndreas Gohrcode means all the source code for all modules it contains, plus any
158*5bfd2b37SAndreas Gohrassociated interface definition files, plus the scripts used to
159*5bfd2b37SAndreas Gohrcontrol compilation and installation of the executable.  However, as a
160*5bfd2b37SAndreas Gohrspecial exception, the source code distributed need not include
161*5bfd2b37SAndreas Gohranything that is normally distributed (in either source or binary
162*5bfd2b37SAndreas Gohrform) with the major components (compiler, kernel, and so on) of the
163*5bfd2b37SAndreas Gohroperating system on which the executable runs, unless that component
164*5bfd2b37SAndreas Gohritself accompanies the executable.
165*5bfd2b37SAndreas Gohr
166*5bfd2b37SAndreas GohrIf distribution of executable or object code is made by offering
167*5bfd2b37SAndreas Gohraccess to copy from a designated place, then offering equivalent
168*5bfd2b37SAndreas Gohraccess to copy the source code from the same place counts as
169*5bfd2b37SAndreas Gohrdistribution of the source code, even though third parties are not
170*5bfd2b37SAndreas Gohrcompelled to copy the source along with the object code.
171*5bfd2b37SAndreas Gohr
172*5bfd2b37SAndreas Gohr  4. You may not copy, modify, sublicense, or distribute the Program
173*5bfd2b37SAndreas Gohrexcept as expressly provided under this License.  Any attempt
174*5bfd2b37SAndreas Gohrotherwise to copy, modify, sublicense or distribute the Program is
175*5bfd2b37SAndreas Gohrvoid, and will automatically terminate your rights under this License.
176*5bfd2b37SAndreas GohrHowever, parties who have received copies, or rights, from you under
177*5bfd2b37SAndreas Gohrthis License will not have their licenses terminated so long as such
178*5bfd2b37SAndreas Gohrparties remain in full compliance.
179*5bfd2b37SAndreas Gohr
180*5bfd2b37SAndreas Gohr  5. You are not required to accept this License, since you have not
181*5bfd2b37SAndreas Gohrsigned it.  However, nothing else grants you permission to modify or
182*5bfd2b37SAndreas Gohrdistribute the Program or its derivative works.  These actions are
183*5bfd2b37SAndreas Gohrprohibited by law if you do not accept this License.  Therefore, by
184*5bfd2b37SAndreas Gohrmodifying or distributing the Program (or any work based on the
185*5bfd2b37SAndreas GohrProgram), you indicate your acceptance of this License to do so, and
186*5bfd2b37SAndreas Gohrall its terms and conditions for copying, distributing or modifying
187*5bfd2b37SAndreas Gohrthe Program or works based on it.
188*5bfd2b37SAndreas Gohr
189*5bfd2b37SAndreas Gohr  6. Each time you redistribute the Program (or any work based on the
190*5bfd2b37SAndreas GohrProgram), the recipient automatically receives a license from the
191*5bfd2b37SAndreas Gohroriginal licensor to copy, distribute or modify the Program subject to
192*5bfd2b37SAndreas Gohrthese terms and conditions.  You may not impose any further
193*5bfd2b37SAndreas Gohrrestrictions on the recipients' exercise of the rights granted herein.
194*5bfd2b37SAndreas GohrYou are not responsible for enforcing compliance by third parties to
195*5bfd2b37SAndreas Gohrthis License.
196*5bfd2b37SAndreas Gohr
197*5bfd2b37SAndreas Gohr  7. If, as a consequence of a court judgment or allegation of patent
198*5bfd2b37SAndreas Gohrinfringement or for any other reason (not limited to patent issues),
199*5bfd2b37SAndreas Gohrconditions are imposed on you (whether by court order, agreement or
200*5bfd2b37SAndreas Gohrotherwise) that contradict the conditions of this License, they do not
201*5bfd2b37SAndreas Gohrexcuse you from the conditions of this License.  If you cannot
202*5bfd2b37SAndreas Gohrdistribute so as to satisfy simultaneously your obligations under this
203*5bfd2b37SAndreas GohrLicense and any other pertinent obligations, then as a consequence you
204*5bfd2b37SAndreas Gohrmay not distribute the Program at all.  For example, if a patent
205*5bfd2b37SAndreas Gohrlicense would not permit royalty-free redistribution of the Program by
206*5bfd2b37SAndreas Gohrall those who receive copies directly or indirectly through you, then
207*5bfd2b37SAndreas Gohrthe only way you could satisfy both it and this License would be to
208*5bfd2b37SAndreas Gohrrefrain entirely from distribution of the Program.
209*5bfd2b37SAndreas Gohr
210*5bfd2b37SAndreas GohrIf any portion of this section is held invalid or unenforceable under
211*5bfd2b37SAndreas Gohrany particular circumstance, the balance of the section is intended to
212*5bfd2b37SAndreas Gohrapply and the section as a whole is intended to apply in other
213*5bfd2b37SAndreas Gohrcircumstances.
214*5bfd2b37SAndreas Gohr
215*5bfd2b37SAndreas GohrIt is not the purpose of this section to induce you to infringe any
216*5bfd2b37SAndreas Gohrpatents or other property right claims or to contest validity of any
217*5bfd2b37SAndreas Gohrsuch claims; this section has the sole purpose of protecting the
218*5bfd2b37SAndreas Gohrintegrity of the free software distribution system, which is
219*5bfd2b37SAndreas Gohrimplemented by public license practices.  Many people have made
220*5bfd2b37SAndreas Gohrgenerous contributions to the wide range of software distributed
221*5bfd2b37SAndreas Gohrthrough that system in reliance on consistent application of that
222*5bfd2b37SAndreas Gohrsystem; it is up to the author/donor to decide if he or she is willing
223*5bfd2b37SAndreas Gohrto distribute software through any other system and a licensee cannot
224*5bfd2b37SAndreas Gohrimpose that choice.
225*5bfd2b37SAndreas Gohr
226*5bfd2b37SAndreas GohrThis section is intended to make thoroughly clear what is believed to
227*5bfd2b37SAndreas Gohrbe a consequence of the rest of this License.
228*5bfd2b37SAndreas Gohr
229*5bfd2b37SAndreas Gohr  8. If the distribution and/or use of the Program is restricted in
230*5bfd2b37SAndreas Gohrcertain countries either by patents or by copyrighted interfaces, the
231*5bfd2b37SAndreas Gohroriginal copyright holder who places the Program under this License
232*5bfd2b37SAndreas Gohrmay add an explicit geographical distribution limitation excluding
233*5bfd2b37SAndreas Gohrthose countries, so that distribution is permitted only in or among
234*5bfd2b37SAndreas Gohrcountries not thus excluded.  In such case, this License incorporates
235*5bfd2b37SAndreas Gohrthe limitation as if written in the body of this License.
236*5bfd2b37SAndreas Gohr
237*5bfd2b37SAndreas Gohr  9. The Free Software Foundation may publish revised and/or new versions
238*5bfd2b37SAndreas Gohrof the General Public License from time to time.  Such new versions will
239*5bfd2b37SAndreas Gohrbe similar in spirit to the present version, but may differ in detail to
240*5bfd2b37SAndreas Gohraddress new problems or concerns.
241*5bfd2b37SAndreas Gohr
242*5bfd2b37SAndreas GohrEach version is given a distinguishing version number.  If the Program
243*5bfd2b37SAndreas Gohrspecifies a version number of this License which applies to it and "any
244*5bfd2b37SAndreas Gohrlater version", you have the option of following the terms and conditions
245*5bfd2b37SAndreas Gohreither of that version or of any later version published by the Free
246*5bfd2b37SAndreas GohrSoftware Foundation.  If the Program does not specify a version number of
247*5bfd2b37SAndreas Gohrthis License, you may choose any version ever published by the Free Software
248*5bfd2b37SAndreas GohrFoundation.
249*5bfd2b37SAndreas Gohr
250*5bfd2b37SAndreas Gohr  10. If you wish to incorporate parts of the Program into other free
251*5bfd2b37SAndreas Gohrprograms whose distribution conditions are different, write to the author
252*5bfd2b37SAndreas Gohrto ask for permission.  For software which is copyrighted by the Free
253*5bfd2b37SAndreas GohrSoftware Foundation, write to the Free Software Foundation; we sometimes
254*5bfd2b37SAndreas Gohrmake exceptions for this.  Our decision will be guided by the two goals
255*5bfd2b37SAndreas Gohrof preserving the free status of all derivatives of our free software and
256*5bfd2b37SAndreas Gohrof promoting the sharing and reuse of software generally.
257*5bfd2b37SAndreas Gohr
258*5bfd2b37SAndreas Gohr                            NO WARRANTY
259*5bfd2b37SAndreas Gohr
260*5bfd2b37SAndreas Gohr  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
261*5bfd2b37SAndreas GohrFOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
262*5bfd2b37SAndreas GohrOTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
263*5bfd2b37SAndreas GohrPROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
264*5bfd2b37SAndreas GohrOR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
265*5bfd2b37SAndreas GohrMERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
266*5bfd2b37SAndreas GohrTO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
267*5bfd2b37SAndreas GohrPROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
268*5bfd2b37SAndreas GohrREPAIR OR CORRECTION.
269*5bfd2b37SAndreas Gohr
270*5bfd2b37SAndreas Gohr  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
271*5bfd2b37SAndreas GohrWILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
272*5bfd2b37SAndreas GohrREDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
273*5bfd2b37SAndreas GohrINCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
274*5bfd2b37SAndreas GohrOUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
275*5bfd2b37SAndreas GohrTO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
276*5bfd2b37SAndreas GohrYOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
277*5bfd2b37SAndreas GohrPROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
278*5bfd2b37SAndreas GohrPOSSIBILITY OF SUCH DAMAGES.
279*5bfd2b37SAndreas Gohr
280*5bfd2b37SAndreas Gohr                     END OF TERMS AND CONDITIONS
281*5bfd2b37SAndreas Gohr
282*5bfd2b37SAndreas Gohr            How to Apply These Terms to Your New Programs
283*5bfd2b37SAndreas Gohr
284*5bfd2b37SAndreas Gohr  If you develop a new program, and you want it to be of the greatest
285*5bfd2b37SAndreas Gohrpossible use to the public, the best way to achieve this is to make it
286*5bfd2b37SAndreas Gohrfree software which everyone can redistribute and change under these terms.
287*5bfd2b37SAndreas Gohr
288*5bfd2b37SAndreas Gohr  To do so, attach the following notices to the program.  It is safest
289*5bfd2b37SAndreas Gohrto attach them to the start of each source file to most effectively
290*5bfd2b37SAndreas Gohrconvey the exclusion of warranty; and each file should have at least
291*5bfd2b37SAndreas Gohrthe "copyright" line and a pointer to where the full notice is found.

312*5bfd2b37SAndreas GohrIf the program is interactive, make it output a short notice like this
313*5bfd2b37SAndreas Gohrwhen it starts in an interactive mode:

315*5bfd2b37SAndreas Gohr    Gnomovision version 69, Copyright (C) year name of author
316*5bfd2b37SAndreas Gohr    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.

320*5bfd2b37SAndreas GohrThe hypothetical commands `show w' and `show c' should show the appropriate
321*5bfd2b37SAndreas Gohrparts of the General Public License.  Of course, the commands you use may
322*5bfd2b37SAndreas Gohrbe called something other than `show w' and `show c'; they could even be
323*5bfd2b37SAndreas Gohrmouse-clicks or menu items--whatever suits your program.

325*5bfd2b37SAndreas GohrYou should also get your employer (if you work as a programmer) or your

327*5bfd2b37SAndreas Gohrnecessary.  Here is a sample; alter the names:
