How to use git-svnimport without trunk, tags and branches?

Hi,

I have searched the archive but did not found any hint for my problem.
Perhaps I did not have the right search pattern, but see yourself:

The most important thing prior of using git was to import my subversion
repositories. It seems to be quite easy if the SVN-repositories are of
common structure using the trunk, tags and branches structure.

But times ago I have had the idea of not using the traditional structure
of subversion for some of my repositories but using the repository
directly as single directory - no trunk, no tags, no branches. That was
because I thought only a geek would have the "complicated" way for only
a few files without any need for tags and branches.
And now the git-svnimport does not seem to be able to handle a SVN-repos
structure like mine:

~/svnrepos/
      |------- projectA
                  |---- foo.cpp
                  |---- foo.h

I want to import projectA into git _with_ the commit-history (there are
of course no tags and no branches).
Is there a way to do that with git-svnimport? Or do I have to throw away
all the details, checkout projectA and reimport it as initial version
with git?

Any hints are warmly appreciated.

Ciao, Georg
