conversion from svn with renames

I'd like to convert svn.codesimply.com/projects' contents to git.

Right now, the content is like this:

  /projects/$PROJECTNAME/{trunk,tags,branches}

git-svnimport does well if I specify projects/$PROJECTNAME/trunk as the trunk directory and that/tags as the tags directory. (I am not interested in bothering with branches.) The problem is this:

For many of the projects, $PROJECTNAME was once "foo" and is now "bar." git-svnimport only imports the history from the current name.

I tried to import foo, then bar, into one git repostiory, but the histories didn't seem to get connected. Sam V. suggested git-filter-branch, but I didn't quite see how to make it do what I wanted.

I would greatly appreciate any advice or help on this conversion.
