Slightly later than I planned, but here goes. The attached files (repack.py
and source.filter come from the iceweasel package) should allow the following
get-orig-source to work:

	uscan --download --destdir . --force-download

I had it working earlier this week but I wanted to check some edge-cases, and
unfortunately with the DEHS redirector currently unavailable the watch file
no longer works. It's possible to invoke the repack.py file as follows
(after downloading wine-mozilla-1.0.0.tar.bz2):

	python debian/repack.py -u 1.0.0+dfsg wine-mozilla-1.0.0.tar.bz2

This will produce a wine-gecko-1.0.0_1.0.0+dfsg.orig.tar.bz2 file (presuming
"wine-gecko-1.0.0" is the source package's name indicated in debian/control).

The script should also work with later releases of wine-gecko but I haven't
checked it yet.
