-- Enforcing the Stop and Search -- This section makes sure that only a human who stops to search will
----------------------------------- remain free to enter. Search bots will aquire a criminal record. :)
---- Details: It will not matter what they are called, nor where they come from, but if they come to cop
-- a quick feel of the inventory they will make themselves known by their deeds and get a fair cop.


function Main(##)                          -- Set NAME to something no-one can have; make it Officious.
  NAME="Hub-Security"
