Here is a disclaimer your employer can sign to cover your future work
on GNU software.  If you now have an employer who can claim copyright
on your work, you need to get this disclaimer before you can sign an
assignment-in-advance.

Much of the disclaimer consists of a description of which kinds of
work it applies to.  This description is just a suggestion--your
employer can replace it with any description that says clearly which
kinds of work they want to disclaim and which kinds they don't.
