 Plugin to check several Woot sites via an RSS feed for Nagios

 This check curls the site http://www.zoolert.com/woot-tracker/rss.xml for the latest Woots, parses
 the feed, and is dependent on how fast that site updates (seems like a 5 minute lag time). It can
 be used for WootOffs but as mentioned there may be some lag.
 
 The check can check the following Woot sites (others are not listed in the RSS feed)
 woot:  Woot.com
 kids:  Kids Woot
 home:  Home Woot
 sell:  SellOut Woot
 sprt:  Woot Sport
 tech:  Woot Tech

 The check will create a woot<type>.tmp in /tmp. After the initial check it will check the string in
 file and compares it with the parsed data. If they do not match (because the Woot has changed) it
 will throw a CRITICAL Nagios alert. If the strings match it will return OK. On the initial run it 
 will return CRITICAL because the file doesn't exist yet.

 A special thanks to the Nagios Developers for a great program and thanks to the Linux die hards
 that gave me a friendly push to start learning Linux. ;)
