# Using the GPL for expat

Instead of using the Mozilla Public License, you may instead elect to use the GNU General Public License (GPL) for a particular copy of expat. The election to use the GPL is irrevocable for that particular copy. If you do elect to use the GPL, then you must replace the copyright notice on each file with the following:

    expat XML parser

and you must change readme.html to say that an election has been made to use this copy under the GPL. If you redistribute expat, you should also include a copy of the GPL.

Note that I will probably not accept patches under terms that allow me to distribute them only under the GPL.
