TITLE	Bush Application

MODULE	bushapp.c

VERSION	1.0

AUTHOR	TC Peters & GW Keim
	Information Technology Center, Carnegie-Mellon University 

DESCRIPTION
	This is the Application layer for the Bush Inset.

    NB: The comment-symbol "===" indicates areas which are:
	    1 - Questionable
	    OR
	    2 - Arbitrary
	    OR
	    3 - Temporary Hacks
    Such curiosities need be resolved prior to Project Completion...


HISTORY
  08/21/85	Created (TCP)
  01/15/89	Convert to ATK (GW Keim)
  05/01/89	Revise Initializing msg to conform with Majro/Minor Version msg (TCP)
  06/06/89	Added call to chdir() to set the current-working-directory to the 
	               path specified on the command line; (GW Keim)
  07/05/89	Use super_ParseArgs (TCP)
  07/28/89	Changed all occurances of AptTree to just Tree; (GW Keim)
  09/07/89	Set V1.0 msg (TCP)
