I had to make a couple small changes to the python script "cfnn", but
otherwise your system works like a champ. Thanks very much. Here's
the diff I used.
[...@oriental 617 ~]$ diff /tmp/cfnn py/cfnn

< page = httplib2.Http(cache="/home/scott/.netrwcache").request
(url,"GET")
< collections_soup.feed(page[1])
