There was some more typing involved and I hate typing, plus I had to deal with a non standard SVN layout that by experience I think it's like a second standard. So I included all the hints found there and somewhere else in a "one click" script that tries to do everything automatically. Since it's automatic you might end up with something close but not exactly as you need, so feel free to tweak as much as you want (as I did with Frank's recipe ;) ).
You can download the script here and run it
sh convert_svn_to_git.sh -r path/to/svn/repo -a path/to/authorsfile
