But currently NPL files remain NPL. Netscape has the right to
relicense them under the MPL (because they have the right to relicense
them under anything) but have delayed doing so because of
considerations about whether they should be licsenced under the MPL or
a dual MPL/GNU GPL arrangment that will allow parts of the Mozilla
code to be used in GNU GPL'd programs.
Me, I say don't bother. It's the GNU GPL, not the MPL, that makes the
two licsenses incompatable.
