This program is also available under different license from
Carlo von Loesch and symlynX. To this purpose all copyright
owners until 2010 grant Carlo von Loesch and symlynX the right
to use and license this program in whatever suitable way.
By the act of submitting code to the psyced maintainers you guarantee
that you are either the author and copyright owner of the contribution
you are making, or that you have a license to use said contribution in
a way compatible with our licenses. If you fail to do so, you
remain the sole responsible for your actions; no part of the
responsibility will be transferred to symlynX.
This means, for example, that you cannot contribute code elements
which stem from an other GPL project, as this would not comply with
the MIT license requirement after 2010.
You can however keep this kind of modifications to yourself, or
publish your own GPL licensed fork of this software, or - in agreement
with us - add optional parts to this software clearly marked as not
adhering to this license.
