as per http://drupal.org/node/101009, the file should contain something like
; $Id$ name = Http Headers description = For each ContentType, allows you to define the 'Expires' and 'Last-Modified' http headers.
usage of the version attribute is discouraged, i'm not sure core = 5.x is valid for a D5 module
