# abstract:     This Bourne Shell script installs the scripts from the
#		bin/scripts directory to the bin directory and
#		installs help related files and links.
#
# note(s):      1. This routine must be called using a . (period)
#
#		2. Updates the bin scripts.
#
#		3. Always change
#
#		   MATLAB:
#
#		   TOOLBOXES:
#
#		   a. Simulink: put in include file links
#		   b. Runtime: Add a link to the MATLAB startup script
#			       in toolbox/runtime
