Extract an SVN subtree - Import into Git

This script will extract a subtree from the SVN repository in 'svnRepo', and import it into a new Git repository that can be found in 'gitRepo'

It is built from scripts found on SVN and Git

if [ "$EXTRACT_PATH" = "" ]; then
  echo "Please provide \$EXTRACT_PATH"
  exit 1
