In my previous article,  I quoted several shell scripts.
Steve Hayman <sahayman@watmath.waterloo.edu> pointed out
to me that the shell scripts could be further simplified
by the use of an oft overlooked feature of the Bourne
Shell.  For example, the shell script I originally had as:

	#! /bin/sh
	case "$#" in
	0) exec /usenet/bin/`/usr/bin/basename $0` ;;
	*) exec /usenet/bin/`/usr/bin/basename $0` "$@" ;;
	esac

can be re-written as:

	#! /bin/sh
	exec /usenet/bin/`/usr/bin/basename $0` ${1+"$@"}

and similiar changes are possible with the other shell scripts
as well.  Thanks Steve.
