# GETTING STARTED
#
# Run this program as root from cron, preferably at least daily. Running
# as root is optional, but will preserve the various modes and ownerships
# of log files in "~mailman/logs". If any entries are in "errors" or
# "smtp-errors", they will be mailed to the mailman owner address.
#
# Set COMPRESS_LOGFILES_WITH in mm_cfg.py to "gzip" to get rotated logfiles
# to be compressed.
#
# Hacked from some existing Mailman code by
# Sean Reifschneider <jafo-mailman@tummy.com>
# Please direct questions on this to the above address.
