2. The Free Software Foundation may publish revised and/or new versions of the General Public Li-
cense from time to time. Such new 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 condi-
tions either of that version or of any later version published by the FreeSoftware Foundation. If the Pro-
gram does not specify a version number of this License, you may choose any version ever published by
the Free Software Foundation.
1. If you wish to incorporate parts of the Program into other free programs whose distribution condi-
tions 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 excep-
tions for this. Our decision will be guided by the two goals of preserving the free status of all deriva-
tives of our free software and of promoting the sharing and reuse of software generally.
NO WARRANTY

WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITH-
OUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
CORRECTION.
2. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPY-
RIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS
PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCI-
DENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PRO-
GRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR
LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH
ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POS-
SIBILITY OF SUCH DAMAGES.

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 © yyyy name of author
