RAA - websitiary/0.4.0

websitary (formerly known as websitiary with an extra "i") monitors
webpages, rss feeds, podcasts etc. It 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. This script was
originally planned as a ruby-based websec replacement. For HTML diffs,
it stills relies on the webdiff perl script that comes with websec.

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.

## FEATURES/PROBLEMS:
* Download webpages on defined intervalls
* Compare webpages with previous backups
* Display differences between the current version and the backup
* Provide hooks to post-process the downloaded documents and the diff
