Determining the repository format of a remote repo...

[John Szakmeister]

I did what I thought was the obvious thing and ran:
    bzr info lp:trac-backlog -v

and got the following output:

Standalone branch (format: unnamed)
Location:
  branch root: bzr+ssh://bazaar.launchpad.net/~trac-backlog-team/trac-backlog/trunk/

Related branches:
  parent branch:
bzr+ssh://bazaar.launchpad.net/%7Ejszakmeister/%2Bjunk/trac-backlog/

Format:
       control: bzr remote bzrdir
        branch: Remote BZR Branch
    repository: bzr remote repository

Branch history:
        36 revisions
        55 days old
   first revision: Wed 2009-08-05 10:24:28 -0400
  latest revision: Tue 2009-09-22 13:24:11 -0400

Repository:
        37 revisions


There is some useful information there, but the format block is almost
completely useless.  Is there some other command I should be using to
determine the format of a remote repo?  I'd like to avoid the overhead
of converting one format into another, and I'd also like to make sure
that a number of my branches are in the '2a' format.

Thanks!
