Ok, Here they are.

  * cleanup.pl -- should run every sunday evening at 11:30PM. 
  * notice_week.pl -- should run every sunday evening at 11:40PM, and
    mails out, to all listservs, a summary of all notices that will
    take place in the upcoming week.
  * notice_mailer.pl -- should run every evening at 11:55PM, and
    mails out notices for new or modified events that will take place
    before the next weekly posting.
  
I've run them both all hand and they work fine. You may need to modify
the user under which the programs run, to ensure taht they return address
is set appropriately --  both should run under user 'www' (or something
similar)
