# FILE: setbg-ksh
# AUTHOR: Greg Schenzel
# DESCR: This is the KornShell version of my "setbg" script.
#   It requires the following:
#     xdpyinfo(1) of X11R6
#     qiv(1), image viewer
#     ksh(1), KornShell
#     bc(1), arbitrary precision calculator
#     awk/ls/grep/wc, standard unix tools
# NOTE: Instead of depending on the random(6) bsd game, this script
#   depends on ksh(1) and bc(1). Therefor, it is more likely to work
#   on commercial unix and NetBSD/OpenBSD without "games" installed.
#   If you run Linux and don't have either bsdgames or ksh installed,
#   then you need one or the other. Debian users can apt-get the
#   pdksh package.
