versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and conditions either of that version or of any later version published by
the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever
published by the Free Software Foundation.
11. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the
author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software
Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all
derivatives of our free software and of promoting the sharing and reuse of software generally.

PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

How to Apply These Terms to Your New Programs 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

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

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.
