Releasing
If this is a new package, you need to do the following for tagging to work
(from the root of the svn checkout of the package):
svn propset svn-bp:tagsUrl svn+ssh://svn.debian.org/svn/pkg-gnome/section/package-name debian/
To release use the following:
dch -r # Changes the distribution from UNRELEASED to unstable
svn-buildpackage --svn-only-tag # Creates a tag
Then sign and upload your package (or ask on #gnome-debian for someone to
sponsor).
