tla's whole archive system is different to CVS's.  In the archive, files
are NEVER deleted or modified, so you don't need permissions to do
either.  All that happens is a new directory is created (below the
location of the previous revision), and a "lock directory" is moved from
the previous revision's dir to the new one.

So, uh, if you set your umask correctly, it will all Just Work :-)
