CODESYS Forge

#!/usr/bin/python
#
# This module is a wrapper for a locally installed SVN command line client.
# It can be used to find URLs of CODESYS projects within a repository, or to
# checkout all files outside of CODESYS projects.
#
# - svn_list:
# a wrapper for the "svn list" command, supporting recursive lists
#
# - svn_get_directories_with_codesys_projects / svn_get_directories_without_codesys_projects:
# return directories with or without CODESYS projects. Can be used to find
# CODESYS library URLs in repositories.
#
# - svn_checkout_non_codesys:
# Checkout top-level directory w/o content.
# Then update all directories, which are not containing any CODESYS projects.
#
