CVS lock and EMACS

[Bertrand Guiheneuf <Bertrand Guiheneuf inria fr>]

Hi,

I have the following problem with cvs'ed files.
When I edit a file with emacs and then quit emacs, I can not edit
them back cause he puts them as read-only until I commit them

Does anyone knows how to tell emacs to let me edit the file?

Thanks,

	Bertrand
