I love cvsup, but lately we DragonFly fans are completely dependent on a
binary cvsup package because ezm3 won't compile.

The obvious solution is to use csup, which is a cvsup-workalike written
in C.  It works flawlessly on FreeBSD and NetBSD but not (yet) on DFBSD
because of the newer version of cvs that we use.

I've emailed the csup guru (Maxime Henrion) about updating csup, but
I've had no answer from him.  I hope Maxime is in good health and is
just too busy to deal with csup, but I really don't know.

Anyone who is interested in updating csup can get the sources here:
