#!/usr/bin/env python
# Find paths matching directories in subversion repository

# TODO:
# * Limit search depth
# * Add option to case [in]sensitive
# * Handling of svn errors
# * Support more of "find" predicates (-type, -and, -mtime ...)
# * Another porject: Pre index (using swish-e ...) and update only from
# changelog
