61 Preamble
62
63 The licenses for most software are designed to take away your
64 freedom to share and change it. By contrast, the GNU General Public
65 License is intended to guarantee your freedom to share and change free
66 software--to make sure the software is free for all its users. This
67 General Public License applies to most of the Free Software
68 Foundation's software and to any other program whose authors commit to
69 using it. (Some other Free Software Foundation software is covered by
70 the GNU Library General Public License instead.) You can apply it to
71 your programs, too.";
