I think I once made an even simpler script for preventing mods to tagged
project which just prevented anything but (A)adds to any path with "tags" in
it.

I have also looked around and did not find much that was really
helpful. I ended up
writing something that works for me, although it probably still has some
holes.
Some things to watch out for:
* paths being deleted from a tag after it is created
* someone deleting the entire 'tags' directory.***
* mixed revision tags may need special handling.
*** This really happened, and although it was trivial to just copy the
tags directory from an earlier revision and recover all the tags, this
is a rather unsatisfactory fix.
This changes the history of the tags, such that log --stop-on-copy now
reports
the copy of the tag directory, not the copy that created the tag.
(This is of course the correct thing for the log command to do.) This
breaks tools such as tksvn that abuse that option to log. We ended up
doing a dump/load to remove the offending
revisions so that our history would not be screwed up the the extra copy.

(I'll see if I can get permission to publish the script, although that
could take a while.)
