Best practice for bzr-svn mirror?

[Jonathan Lange]

Hello,

I was thinking about setting up a mirror of a Subversion project into
Bazaar. The project uses branch-based development, so I'd like each of
Subversion "branches" to be available as Bazaar branches, as well as
the trunk.

Ideally, people would be able to branch from the trunk and push it to
Launchpad or whatever.

Has anyone done this kind of thing before? Is there a howto? Any gotchas?
