# A modification of Dean Clatworthy's deploy script as found here: https://github.com/deanc/wordpress-plugin-git-svn
# The difference is that this script lives in the plugin's git repo & doesn't require an existing SVN repo.
# Kanzu Code: Also, it automatically discovers files/folders in svn that no longer exist in git and removes them
