# directives that can be used by rsync to copy just the indicated files using
# an --exclude-from=FILE or -f'. FILE' option. To be able to delete files on
# the receiving side, either use --delete-excluded or change the exclude (-)
# rules to hide filter rules (H) that only affect the sending side.
