Installing Squid

I spent last evening installing Squid, an open-source caching proxy for the Web. I am attempting to filter out porn, spyware, warez, etc., from my son's computer. I think I finally have it working, after downloading a blacklist from SquidGuard. I couldn't get SquidGuard to compile under Win2K/Cygwin, so I wrote a quick and dirty perl script to convert the blacklist urls and domains into regular expressions.
