That sounds great!

Oh, yes, I see it. That's good!

Hmm. Ok, maybe I didn't explain myself very well.

I want to identify all the symbolic tags from CVS and find what Arch
revision they match, to do a 'tla cacherev $REVISION'. It looks I'll
want to do a SELECT from the sqlite database to get the csets and then
parse the tla logs for CSCVSID. Not bad so far.

The ouput of `cscvs cache -T` is a bit bizarre and I don't quite
understand it ;-)

Agreed. And yet, for projects that make simple (read: trivial) use of
branching, it should be possible. At any rate, there are a few
alternatives when mapping CVS branches to Arch.

How feasible would it be to take a stab at solving the "simple" cases?

Not at all: Moodle, , CVS info @

The effort of providing the Arch gateway is part of Eduforge
( The NZVLE project will offer Moodle to a
large number of tertiaries in NZ. If the upstream developers are
happy, we'll offer the arch gateway publicly, as well as using it for
our own needs.

So far, Moodle is just shy of 8500 changesets, and runs a pretty
simple tagging/branching scheme as you can see in .
