#	XTVI SSATEUR: Site-Specific Automatic Torrent Extractor Using RSS
#	Authored By: Andrew Rowls
#	!--> Works ONLY with torrent feeds from http://www.xtvi.com/all_tv_shows
#	!--> If this script successfully parses feeds from any other site, it's sheer coincidence
#	#####==============--------------
#	IMPORTANT: XTVI has implemented CAPTCHAs for a reason.  "To protect our servers from heavy
#		traffic".  And I agree.  While I don't believe this script will particularly tax XTVI'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 XTVI
#			freezes, bans, locks, or warns you, for whatever reason.
