#		icleanpe (when executed from the CDROM)
#
# abstract:     Initial cleaning of the $MATLAB files associated with
#		the piece designated by the value of the environment
#		variable PIECE_PATH. This is ONLY for cleaning out
#		5.x files that must be deleted before taring over them
#		or can't be deleted by looking at the differences between
#		b and .b files.
#
# note(s):      1. If $MATLAB/update/pd/$piece_path/.b exists then there
#		   is nothing to do.
#
#		2. The following variables must exist in the environment
#
#		       MATLAB
#		       PIECE_PATH
#
#		3. This file is sourced by the normal install but executed
#		   by the CDROM install.
