Debian and copyrights

["Baptiste SIMON" <baptiste.simon@e-glop.net>]

Hi people,

I'd like to know how debian has relsolved the copyright question. In fact,
anyone which is releasing his software under something like GPL or LGPL is
able, if he is still holding the code copyright, to release a next release
under any other license.
I'd like to prevent this kind of problem without giving copyright to FSF
(because, I'm not the alone on my project).

I'm interesting about how you've relsolved this problem.

note: I've not subscribed to your mailing list, so I would be pleased if
you can add my to Cc:. Thanks in advance.
