+ Everyone is permitted to copy and distribute verbatim copies |
|
7 |
+ of this license document, but changing it is not allowed. |

|
9 |
+ Preamble |
|
10 |
+ |
|
11 |
+ The licenses for most software are designed to take away your |
|
12 |
+freedom to share and change it. By contrast, the GNU General Public |
|
13 |
+License is intended to guarantee your freedom to share and change free |
|
14 |
+software--to make sure the software is free for all its users. This |
|
15 |
+General Public License applies to most of the Free Software |
|
16 |
+Foundation's software and to any other program whose authors commit to |
|
17 |
+using it. (Some other Free Software Foundation software is covered by |
|
18 |
+the GNU Lesser General Public License instead.) You can apply it to |
|
19 |
+your programs, too. |
|
20 |
+ |
|
21 |
+ When we speak of free software, we are referring to freedom, not |
|
22 |
+price. Our General Public Licenses are designed to make sure that you |
|
23 |
+have the freedom to distribute copies of free software (and charge for |
|
24 |
+this service if you wish), that you receive source code or can get it |
|
25 |
+if you want it, that you can change the software or use pieces of it |
|
26 |
+in new free programs; and that you know you can do these things. |
|
27 |
+ |
|
28 |
+ To protect your rights, we need to make restrictions that forbid |
|
29 |
+anyone to deny you these rights or to ask you to surrender the rights. |
|
30 |
+These restrictions translate to certain responsibilities for you if you |
|
31 |
+distribute copies of the software, or if you modify it. |
|
32 |
+ |
|
33 |
+ For example, if you distribute copies of such a program, whether |
|
34 |
+gratis or for a fee, you must give the recipients all the rights that |
|
35 |
+you have. You must make sure that they, too, receive or can get the |
|
36 |
+source code. And you must show them these terms so they know their |
|
37 |
+rights. |
|
38 |
+ |
|
39 |
+ We protect your rights with two steps: (1) copyright the software, and |
|
40 |
+(2) offer you this license which gives you legal permission to copy, |
|
41 |
+distribute and/or modify the software. |
|
42 |
+ |
|
43 |
+ Also, for each author's protection and ours, we want to make certain |
|
44 |
+that everyone understands that there is no warranty for this free |
|
45 |
+software. If the software is modified by someone else and passed on, we |
|
46 |
+want its recipients to know that what they have is not the original, so |
|
47 |
+that any problems introduced by others will not reflect on the original |
|
48 |
+authors' reputations. |
|
49 |
+ |
|
50 |
+ Finally, any free program is threatened constantly by software |
|
51 |
+patents. We wish to avoid the danger that redistributors of a free |
|
52 |
+program will individually obtain patent licenses, in effect making the |
|
53 |
+program proprietary. To prevent this, we have made it clear that any |
|
54 |
+patent must be licensed for everyone's free use or not licensed at all. |
|
55 |
+ |
|
56 |
+ The precise terms and conditions for copying, distribution and |
|
57 |
+modification follow. |
|
58 |
+ |
|
59 |
+ GNU GENERAL PUBLIC LICENSE |
|
60 |
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION |
|
61 |
+ |
|
62 |
+ 0. This License applies to any program or other work which contains |
|
63 |
+a notice placed by the copyright holder saying it may be distributed |
|
64 |
+under the terms of this General Public License. The "Program", below, |
|
65 |
+refers to any such program or work, and a "work based on the Program" |
|
66 |
+means either the Program or any derivative work under copyright law: |
|
67 |
+that is to say, a work containing the Program or a portion of it, |
|
68 |
+either verbatim or with modifications and/or translated into another |
|
69 |
+language. (Hereinafter, translation is included without limitation in |
|
70 |
+the term "modification".) Each licensee is addressed as "you". |
|
71 |
+ |
|
72 |
+Activities other than copying, distribution and modification are not |
|
73 |
+covered by this License; they are outside its scope. The act of |
|
74 |
+running the Program is not restricted, and the output from the Program |
|
75 |
+is covered only if its contents constitute a work based on the |
|
76 |
+Program (independent of having been made by running the Program). |
|
77 |
+Whether that is true depends on what the Program does. |
|
78 |
+ |
|
79 |
+ 1. You may copy and distribute verbatim copies of the Program's |
|
80 |
+source code as you receive it, in any medium, provided that you |
|
81 |
+conspicuously and appropriately publish on each copy an appropriate |
|
82 |
+copyright notice and disclaimer of warranty; keep intact all the |
|
83 |
+notices that refer to this License and to the absence of any warranty; |
|
