#
# This program converts image strings whose names are given on the command
# line to GIF files. Image files are expected to have the suffix .ims.
#
# The GIF files are written to files with the basenames of the image string
# files and the suffix "gif".
#
# The following option is supported:
#
# -l read Icon literal instead of plain string
#
############################################################################
#
# Requires: Version 9 graphics
