TODO

 - rrdsquish: log random URLs from pages visited -- incorporate these into the
   graphs :)

 - Find a way of directing the user to his own squishy graphs

 - Add squish logo to pages (and fix the logo!)

 - BUG: rrdsquish uses floating point for just about everything, which is slow
   We should switch to rrdtool - which involves making it able to incorporate
   our type of information.

 - BUG: installation allows any part to be executed via CGI -- you can probably
   feed squish.pl fake lines with a POST command.

DONE
 - squish.pl: write a log of who is over the limits

 - Installation:

	-- modify squid.conf

	-- setup cron to check every 5 minutes

	-- install squish.cgi in cgi-bin directory

 - squish.conf: Administration: allow setting of limits on a per user basis
   (rewrite the config file...)

 - squish.cgi: Print out a graph of what has been happening
