I want to write an application that uses the Perl Tk module and license my code under GPL<br>It is the license of Perl Tk that buffles me :<br>At the module's site <a href="http://search.cpan.org/%7Esrezic/Tk-804.029/" target="_blank">http://search.cpan.org/~srezic/Tk-804.029/</a><br>
it says :<br>"The distribution is licensed under a license that is not approved by <a href="http://www.opensource.org" target="_blank">www.opensource.org</a> but that allows distribution without restrictions "<br>
<br>then inside Tk.pm it says :<br>
"# This program is free software; you can redistribute it and/or<br># modify it under the same terms as Perl itself, subject<br># to additional disclaimer in Tk/license.terms due to partial<br># derivation from Tk8.0 sources."<br>
<br>and then in the Tk/license.terms says :<br>"The authors hereby grant permission to use, copy, modify, distribute,<br>and license this software and its documentation for any purpose, provided<br>that existing copyright notices are retained in all copies and that this<br>
notice is included verbatim in any distributions. No written agreement,<br>license, or royalty fee is required for any of the authorized uses.<br>Modifications to this software may be copyrighted by their authors<br>and need not follow the licensing terms described here, provided that<br>
the new terms are clearly indicated on the first page of each file where<br>they apply."<br><br>What does that actually mean? where should I put those terms? <br>inside my application's source code distribution should I also include Tk module's source code ?<br>
<br>Thanks in advance<br>
