   2#   cron.py
   3#
   4#   List the logged (executed) cron jobs and their commands (uses syslog file)
   5#
   6#   NOTE: This file is now deprecated in favour of the newer journald mechanism
   7#   used in cron-journald.py. This parser is still functional but is slower and
   8#   has less features. Please switch over if possible.
