   3 # This script reads the auto-properties defined in the
   4 # $HOME/.subversion/config file and applies them recursively to all
   5 # the files and directories in the current working copy.  It may
   6 # behave differently than the Subversion command line; where the
   7 # subversion command line may only apply a single matching
   8 # auto-property to a single pathname, this script will apply all
   9 # matching lines to a single pathname.
  10 #
  11 # To do:
  12 # 1) Switch to using the Subversion Python bindings.
  13 # 2) Allow a command line option to specify the configuration file to
  14 #    load the auto-properties from.
