spam-catcher using a collaborative filtering network
 Pyzor is a collaborative, networked system to detect and block spam using
 identifying digests of messages.
 .
 Pyzor initially started out to be merely a Python implementation of Razor,
 but due to the protocol and the fact that Razor's server is not software
 libre, I decided to implement Pyzor with a new protocol and release the
 entire system as software libre.
 .
 Since the entire system is released under the GPL, people are free to host
 their own independent servers.
 Server peering is planned for a future release.
