Add Subversion files to git

I you need to start a git repository from a Subversion one, and you don't care about history. Then the following should be helpful.

#!/usr/bin/env python

# Add subversion repsotory to a git one
# Run (at top of svn repository)
# git init
# git-add-svn
# git ci -a -m "Initial import from svn $(svn info | grep Revision)"
