A simple Ruby library to parse robots.txt.

Usage:

	robots = Robots.new "Some User Agent"
	assert robots.allowed?("http://www.yelp.com/foo")
	assert !robots.allowed?("http://www.yelp.com/mail?foo=bar")
	robots.other_values("http://foo.com") # gets misc. key/values (i.e. sitemaps)
	
If you want caching, you're on your own.  I suggest marshalling an instance of the parser.
