Yeah - to get this to work I actually have different invocations of
svn_buildbot.py with different --include arguments for each branch, and
a matching --branch argument.  It's a bit ugly, but there wasn't any
other way to do it that I could see.  eg:

${REPOS}/hooks/svn_buildbot.py --repository "$REPOS" \
	--branch trunk --revision "$REV" \
	--bbserver localhost --bbport 9989 \
	--include project/trunk/ &
${REPOS}/hooks/svn_buildbot.py --repository "$REPOS" \
	--branch branches/release-2 --revision "$REV" \
	--bbserver localhost --bbport 9989 \
	--include branches/release-2/ &
...

I also did it this way since I don't want to allow building of _any_
branch - just the official release branches.

Sounds nice to me.

cheers,
