#       Mininova SSATEUR: Site-Specific Automatic Torrent Extractor Using RSS
#       Authored By: Andrew Rowls
#       !--> Works ONLY with torrent feeds from http://www.mininova.org/
#       !--> If this script successfully parses feeds from any other site, it's sheer coincidence
#       #####==============--------------
#       IMPORTANT: While mininova has not implemented CAPTCHAs, you should still be courteous towards them
#		While I don't believe this script will particularly tax mininova's servers simply by being run
#		once, you should not be so rude as to run it many times within a short time span, especially
#		if you have many feeds you check.  Since TV shows typically don't air more than once a week,
#		ideally you should only run this script once a week.  However, since it is typically desirable
#		to have a copy of a show by the day after it airs, I would recommend running the script no more
#		than once per day, at least several hours after the latest show of interest has aired.  For
#		example, my shows typically air around 8-10PM EDT.  The torrents for these shows are guaranteed
#		to show up by 5AM the next morning.  Therefore, I have cron set to run this script once per day at
#               5AM.  This almost guarantees that I will be able to start downloading shows from the
#               previous night.
#               Again, please be courteous when setting this script to run.  And don't blame me if mininova
#			bans your IP for excessive bandwidth usage (or any other reason, for that matter)
