---|
39 | <para> |
---|
40 | The licenses for most software are designed to take away your |
---|
41 | freedom to share and change it. By contrast, the GNU General Public |
---|
42 | License is intended to guarantee your freedom to share and change |
---|
43 | free software - to make sure the software is free for all its users. |
---|
44 | This General Public License applies to most of the Free Software |
---|
45 | Foundation's software and to any other program whose authors commit |
---|
46 | to using it. (Some other Free Software Foundation software is covered |
---|
47 | by the GNU Library General Public License instead.) You can apply it |
---|
48 | to your programs, too. |
---|
49 | </para> |
---|
50 | |
---|
51 | <para> |
---|
52 | When we speak of free software, we are referring to freedom, not price. |
---|
53 | Our General Public Licenses are designed to make sure that you have the |
---|
54 | freedom to distribute copies of free software (and charge for this |
---|
55 | service if you wish), that you receive source code or can get it if you |
---|
56 | want it, that you can change the software or use pieces of it in new free |
---|
57 | programs; and that you know you can do these things. |
---|
58 | </para> |
---|
59 | |
---|
60 | <para> |
---|
61 | To protect your rights, we need to make restrictions that forbid anyone |
---|
62 | to deny you these rights or to ask you to surrender the rights. These |
---|
63 | restrictions translate to certain responsibilities for you if you distribute |
---|
64 | copies of the software, or if you modify it. |
---|
65 | </para> |
---|
66 | |
---|
67 | <para> |
---|
68 | For example, if you distribute copies of such a program, whether gratis or |
---|
69 | for a fee, you must give the recipients all the rights that you have. You |
---|
70 | must make sure that they, too, receive or can get the source code. And you |
---|
71 | must show them these terms so they know their rights. |
---|
72 | </para> |
---|
73 | |
---|
74 | <para> |
---|
75 | We protect your rights with two steps: |
---|

---|

---|
90 | </para> |
---|
91 | |
---|
92 | <para> |
---|
93 | Also, for each author's protection and ours, we want to make certain that |
---|
94 | everyone understands that there is no warranty for this free software. If |
---|
95 | the software is modified by someone else and passed on, we want its |
---|
96 | recipients to know that what they have is not the original, so that any |
---|
97 | problems introduced by others will not reflect on the original authors' |
---|
98 | reputations. |
---|
99 | </para> |
---|
100 | |
---|
101 | <para> |
---|
102 | Finally, any free program is threatened constantly by software patents. |
---|
103 | We wish to avoid the danger that redistributors of a free program will |
---|
104 | individually obtain patent licenses, in effect making the program |
---|
105 | proprietary. To prevent this, we have made it clear that any patent must be |
---|
106 | licensed for everyone's free use or not licensed at all. |

122 | This License applies to any program or other work which contains a notice |
---|
123 | placed by the copyright holder saying it may be distributed under the terms |
---|
124 | of this General Public License. The "Program", below, refers to any such |
---|
125 | program or work, and a <quote>work based on the Program</quote> means either |
---|
126 | the Program or any derivative work under copyright law: that is to say, a |
---|
127 | work containing the Program or a portion of it, either verbatim or with |
---|
128 | modifications and/or translated into another language. (Hereinafter, translation |

129 | is included without limitation in the term <quote>modification</quote>.) Each |

133 | <para> |

134 | Activities other than copying, distribution and modification are not covered by |
---|
135 | this License; they are outside its scope. The act of running the Program is not |

136 | restricted, and the output from the Program is covered only if its contents |
---|
137 | constitute a work based on the Program (independent of having been made by running |
---|
138 | the Program). Whether that is true depends on what the Program does. |

194 | <para> |

207 | These requirements apply to the modified work as a whole. If identifiable sections |
---|
208 | of that work are not derived from the Program, and can be reasonably considered |
---|
209 | independent and separate works in themselves, then this License, and its terms, |
---|
210 | do not apply to those sections when you distribute them as separate works. But when |
---|
211 | you distribute the same sections as part of a whole which is a work based on the |
---|
212 | Program, the distribution of the whole must be on the terms of this License, whose |
---|
213 | permissions for other licensees extend to the entire whole, and thus to each and |
