The attached plugin runs all comments through Akismet,
to determine whether they're spam or not.

I just whipped it up last night, so if anyone has any
ideas on how to improve it, I'm all ears.

You'll need to install the akismet python library from
http://www.voidspace.org.uk/python/modules.shtml#akismet

Also on that page are instructions on how to get the
required 'akismet_key' config variable.  (The page calls
it a "Wordpress Key".)

Later,
Blake.
