tfd.py -- Scrapes a certain set of comics' websites, and spits
          out home-grown RSS feeds for them. 

This is pretty useless now that all of the Sharing Machine comics 
provide RSS feeds, but might serve as an okay example of old-school
screen scraping and XML generation in Python. I hear the cool kids 
use BeautifulSoup (for scraping) and lxml (for XML generation) 
nowadays.
