source: valtobtest/subversion-1.6.2/contrib/client-side/svn_apply_autoprops.py @ 3

#!/usr/bin/env python

# This script reads the auto-properties defined in the
# $HOME/.subversion/config file and applies them recursively to all
# the files and directories in the current working copy.  It may
# behave differently than the Subversion command line; where the
# subversion command line may only apply a single matching
# auto-property to a single pathname, this script will apply all
# matching lines to a single pathname.
#
# To do:
# 1) Switch to using the Subversion Python bindings.
# 2) Allow a command line option to specify the configuration file to
#    load the auto-properties from.
