# Binbot.pl: Reads a list of rss feeds from a file and searches for ke
+ywords, writing matching <title> and
# <link> elements to a new rss file.
# I use it for tracking USENET binaries, but it could be used for any 
+pupose.
#Files: 
#    urls.txt - A text file consisting of URLs to rss feeds, one per l
+ine. 
#        e.g. http://www.whatever.com/some-rss.rss
#    keywords.txt - A text file consisting of keywords to search for, 
+one per line.
# 9/24/06 - switched to URI::Fetch (from LWP::Simple) to allow reading
+ gzip compressed feeds.
