Actually, it is I who should go to bed.

But if you have a mac and want some good time perl code focused on CVS, try this:

Start a terminal app,

export CVSROOT=:pserver:anonymous@cvs-mirror.mozilla.org:/cvsroot
cvs -z9 -q co mozilla/webtools/bonsai mozilla/webtools/registry

Bonzai is no DMG file. It is poorly packaged.

From the README of the project:
"This is Bonsai. See < http://www.mozilla.org/bonsai.html >.

DISCLAIMER

This is not very well packaged code. It's not packaged at all. Don't
come here expecting something you plop in a directory, twiddle a few
things, and you're off and using it. Much work has to be done to get
there. We'd like to get there, but it wasn't clear when that would be,
and so we decided to let people see it first.

Don't believe for a minute that you can use this stuff without first
understanding most of the code."

This kind of shows Bonsai in action:

They have a lot of interesting cvs code in perl, the old school cgi files.
