The GPL is about distribution of software. If you provide your program with sources and allow redistribution under provisions of GPL, it will be free (as you provide some "freedoms" listed in the license statement), even if you earn cash for it. It's "free as in freedom" (or free speech), not as in "free beer". Please, contact your local FSF, CreativeCommons or ISOC lawyer to get an advice if you feel you need a lawyer's assistance. For the brief explanation of the problem, see http://www.gnu.org/philosophy/selling.html. This document should cover most cases. ;) >> Plus, this (sales)person forgot to state clearly, that GPL covers only >> distribution, not the cost of software.

If you obey GPL rules, you're right. The (sales)person you had a conversation with is, well, just a salesperson. Trolltech makes money from selling commercial licenses, so these persons will always try to persuade you to buying a license or two, "just in case". ;) -- Jarek Zgoda http://jpa.berlios.de/ -- http://mail.python.org/mailman/listinfo/python-list
