keeping pkgsrc up to date

[Johannes Hofmann <johannes.hofmann@xxxxxx>]

What do you use to keep your pkgsrc tree up to date?
Anonymous cvs does work but is pretty slow.
The cvsup mirrors seem to be rather busy.
I used the mercurial repo at
http://hg.scode.org/mirror/pkgsrc
for some time, but it seems to be down now.
