Couple of bzr-svn questions...

[John Szakmeister]

I'm looking to write a plug-in to help submit a bundle to a Review
Board server, but I need to get access to a few things.  I need to
determine the repository root for the Subversion server, and I'd like
to be able to determine which Subversion revision the bundle was based
against.  I haven't a clue how to figure out the former (or whether
it's exposed).  The latter looks like it might be available in the
header of the bundle:
  # base_revision_id: svn-v4:ad226f10-a85e-0410-9d03-\
  #   8ae57e21dac2:trunk:241

Can I assume the revision id's will always look like that?

TIA!
