<?php /*

             UPDATE (Apr 14, 2007): Well, it's official. This
             script cannot be relied upon becuase it is not
             100% effective. It has been found by user-agent
             spoofing 'bots and I now get 1-2 smal emails per
             week to this address. I would like to suggest an
             alternive email protection script I wrote [1] or
             my contact forms [2,3]
