# This is an alternate implentation of an RSS feed, it was
# implemented by Darren Chamberlain in response to an item
# in the TODO list of 0.2. Unfortunatly a few moments before
# I received this I had already done rss.pl and uploaded
# 0.3 so i've included this as an alternate example and its
# probably better as he bothers to do things like escaping.
