+ If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. +
+ ++ To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. +
+ ++one line to give the program's name and an idea of what it does. +Copyright (C) yyyy name of author + +This program is free software; you can redistribute it and/or +modify it under the terms of the GNU General Public License +as published by the Free Software Foundation; either version 2 +of the License, or (at your option) any later version. + +This program is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the +GNU General Public License for more details. + +You should have received a copy of the GNU General Public License +along with this program; if not, write to the Free Software +Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, +MA 02110-1301, USA. ++ +
+Also add information on how to contact you by electronic and paper mail. +
+ ++If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: +
+ ++Gnomovision version 69, Copyright (C) year name of author +Gnomovision comes with ABSOLUTELY NO WARRANTY; for details +type `show w'. This is free software, and you are welcome +to redistribute it under certain conditions; type `show c' +for details. ++ +
+The hypothetical commands `show w' and `show c' should show +the appropriate parts of the General Public License. Of course, the +commands you use may be called something other than `show w' and +`show c'; they could even be mouse-clicks or menu items--whatever +suits your program. +
+ ++You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: +
+ + ++Yoyodyne, Inc., hereby disclaims all copyright +interest in the program `Gnomovision' +(which makes passes at compilers) written +by James Hacker. + +signature of Ty Coon, 1 April 1989 +Ty Coon, President of Vice ++ +
+This General Public License does not permit incorporating your program into +proprietary programs. If your program is a subroutine library, you may +consider it more useful to permit linking proprietary applications with the +library. If this is what you want to do, use the +GNU Lesser General Public License +instead of this License. +
