git-svn-import.sh
is the heart of this beast. Therein you'll find a handful of git
sub-commands
that can be used to import your SVN repositories. It helps to think of that file
as a recipe for how you might do your own import, filling in your details as
needed.
If you're up for, I'd love to make it more automated...
Please, fork and improve them as you see fit!
Enjoy,
