git svn clone of messy repository

[Jason Greenbaum <jgbaum@xxxxxxx>]

Hi,

I'm in the process of using git svn to migrate several repos over to
git and one repo, in particular, has a very challenging format.
During the migration, I would also like to reorganize the repo.  It
looks something like this in svn:

myrepo
  trunk
    project_of_interest
    other_project1
    other_project2
    …
  branches
    FF-1.0
      project_of_interest
      other_project1
      other_project2
      …
   FF-1.1
      project_of_interest
      other_project1
      other_project2
      …

There is also a 'tags' directory at the toplevel, but that's not
important to illustrate the issue I'm having.  What I would like to do
is to migrate ONLY the folder called 'project_of_interest' and
preserve it's trunk, branches, and tags.  I'm not sure this is
possible directly with git svn clone, but here is what I've tried:

git svn clone \
--authors-file=$AUTHORS_FILE \
--prefix="" \
--trunk=trunk/project_of_interest \
--branches=branches/FF-1.0/project_of_interest \
--branches=branches/FF-1.1/project_of_interest \
svn://my-svn-server/myrepo \
project_of_interest.git

The trunk seems to become the 'master' branch just fine, but my svn
branches are not pulled down.  I'm not sure I have the syntax right or
if this is even possible without first reorganizing the svn repo in
place, updating the .git/config file, or by some other means.  Any
help would be much appreciated.  I'm happy to provide more info as
needed.

Thanks,

Jason
