You can use "bzr svn-layout" to see what sort of repository layout
bzr-svn thinks it should use for a particular repository. 

See "bzr help svn-layout" for more information on manually setting the
repository layout that should be used. You can use wildcards. 

We can't just rely on considering everything that is derived from trunk
as a branch, as this assumes that there is a main branch - which is not
necessarily true. It would also require finding the ancestry of all
directories in the latest revision to see if they derive from trunk,
which would have performance consequences.

Cheers,

Jelmer
