Hi Jean Roc,
I would suggest to change this tip to something widely accepted, for

Quantum GIS 1.7 is released under the GNU General Public License
[version 3, am I correct?? or "version 3 or above"?].
The GNU General Public License is a free, copyleft license for software

The licenses for most software and other practical works are designed to
take away your freedom to share and change the works. By contrast, the
GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users.

of the Preamble of the GNU GPL v3, here:
This is already translated in many languages here:

discussion with Volker about it . The conclusion was that there is no
but the only way to distribute QGIS currently is under the terms of the
This is because most of the source files are under GPLv2+ (version2 or
later version). However, PAL and the sqlanywhere plugin/provider sources

In my opinion, GPLv3 shouldn't be a problem for the project. From the
page, the major changes seem to be a clause that forbids discriminatory
deals and one that does not allow sueing DRM hackers.
