GPE packaging (at least for my own packages in GPE) has been added to
svn.debian.org (alternative browser front end -
my preference) and available via
svn://svn.debian.org/pkg-gpe/.
Some packages have been converted to dpkg source format 3.0, although only for purposes of using the upstream
.orig.tar.bz2 directly without repacking and for the purposes of testing
svn-buildpackage 0.7.1 support.
