e2guardian binary package in Ubuntu Mantic amd64

 e2guardian filters the content of pages based on many methods
 including phrase matching, PICS filtering and URL filtering. It does
 not purely filter based on a banned list of sites.
 .
 It provides real-time virus scanning capabilities for content access.
 .
 e2guardian is designed to be completely flexible and allows you to tailor
 the filtering to your exact needs. It can be as draconian or as
 unobstructive as you want. The default settings are geared towards what a
 primary school might want but e2guardian puts you in control of what you
 want to block.
 .
 e2guardian requires squid or another similar caching proxy server
 on your local network.
