RAA - websitiary/0.1.0

This is a script for monitoring webpages that reuses other programs
(w3m, diff, webdiff etc.) to do most of the actual work. By default, it
works on an ASCII basis, i.e. with the output of text-based webbrowsers
like w3m (or lynx, links etc.) as the output can easily be
post-processed. With the help of some friends (see the section below on
requirements), it can also work with HTML. E.g., if you have websec
installed, you can also use its webdiff program to show colored diffs.

By default, this script will use w3m to dump HTML pages and then run
diff over the current page and the previous backup. Some pages are
better viewed with lynx or links. Downloaded documents (HTML or ASCII)
can be post-processed (e.g., filtered through some ruby block that
extracts elements via hpricot and the like). Please see the
configuration options below to find out how to change this globally or
for a single source.
