However, nothing else grants you permission to modify ordistribute the Program or its derivative works.  These actions areprohibited by law if you do not accept this License.  Therefore, bymodifying or distributing the Program (or any work based on theProgram), you indicate your acceptance of this License to do so, andall its terms and conditions for copying, distributing or modifyingthe Program or works based on it.@itemEach time you redistribute the Program (or any work based on theProgram), the recipient automatically receives a license from theoriginal licensor to copy, distribute or modify the Program subject tothese terms and conditions.

If you cannotdistribute so as to satisfy simultaneously your obligations under thisLicense and any other pertinent obligations, then as a consequence youmay not distribute the Program at all.  For example, if a patentlicense would not permit royalty-free redistribution of the Program byall those who receive copies directly or indirectly through you, thenthe only way you could satisfy both it and this License would be torefrain entirely from distribution of the Program.If any portion of this section is held invalid or unenforceable underany particular circumstance, the balance of the section is intended toapply and the section as a whole is intended to apply in othercircumstances.It is not the purpose of this section to induce you to infringe anypatents or other property right claims or to contest validity of anysuch claims; this section has the sole purpose of protecting theintegrity of the free software distribution system, which isimplemented by public license practices.  Many people have madegenerous contributions to the wide range of software distributedthrough that system in reliance on consistent application of thatsystem; it is up to the author/donor to decide if he or she is willingto distribute software through any other system and a licensee cannotimpose that choice.This section is intended to make thoroughly clear what is believed tobe a consequence of the rest of this License.@itemIf the distribution and/or use of the Program is restricted incertain countries either by patents or by copyrighted interfaces, theoriginal copyright holder who places the Program under this Licensemay add an explicit geographical distribution limitation excludingthose countries, so that distribution is permitted only in or amongcountries not thus excluded.  In such case, this License incorporatesthe limitation as if written in the body of this License.@itemThe Free Software Foundation may publish revised and/or new versionsof the General Public License from time to time.  Such new versions willbe similar in spirit to the present version, but may differ in detail toaddress new problems or concerns.Each version is given a distinguishing version number.  If the Programspecifies a version number of this License which applies to it and ``anylater version'', you have the option of following the terms and conditionseither of that version or of any later version published by the FreeSoftware Foundation.  If the Program does not specify a version number ofthis License, you may choose any version ever published by the Free SoftwareFoundation.@itemIf you wish to incorporate parts of the Program into other freeprograms whose distribution conditions are different, write to the authorto ask for permission.  For software which is copyrighted by the FreeSoftware Foundation, write to the Free Software Foundation; we sometimesmake exceptions for this.

To do so, attach the following notices to the program.  It is safestto attach them to the start of each source file to most effectivelyconvey the exclusion of warranty; and each file should have at leastthe ``copyright'' line and a pointer to where the full notice is found.@smallexample@var{one line to give the program's name and an idea of what it does.}Copyright (C) 19@var{yy}  @var{name of author}This program is free software; you can redistribute it and/ormodify it under the terms of the GNU General Public Licenseas published by the Free Software Foundation; either version 2of 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 ofMERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
