      This is the RSL for the basic components that relate to the
      AppleEvents and Forms that Ephram uses.

       PLEASE NOTE:
       We are not attempting to define AppleEvents or AppleScript
       here.  That would be an overwhelming waste of time.  We are
       only describing the very abstract levels of the elements of 
       AppleEvents that Ephram makes use of.
