#!/bin/sh

# based on http://john.albin.net/git/convert-subversion-to-git with a some tweeks
# (NB: its quick and dirty, has no error checking and only works on repos structured with a stdlayout i.e. a trunk folder)
# use:
#
# $:./svn-to-git.sh new-repo-name http://user@server/repo/

BARE_REPO_NAME="$1"
SVN_PATH="$2"

cd ~/
