Hi Heiko Stamer:

I saw that in one of dependence of openSkat project you use xskat,
we're trying to find out if is a GPL-Compatible license or not.

In the other hand can you look for another name to your project?

This is because we supports projects of the Free Software movement,
not projects of the Open Source movement.

We are careful about ethical issues and insist on producing software
that is not dependent on proprietary software.

While Open Source as defined by its founders means something pretty
close to Free Software, it's frequently misunderstood.  For more
information, please see
http://www.gnu.org/philosophy/free-software-for-freedom.html.

On the other hand we wish to review your source code, even if it is
not functional, to catch potential legal issues early.

For example, to release your program properly under the GPL you must
include a copyright notice and permission-to-copy statements at the
beginning of every file of source code.  This is explained in
http://www.gnu.org/licenses/gpl-howto.html.  Our review would help
catch potential omissions such as these.

Best regards
