# Unfortunately, the gnuplot demo wants run in the
# /usr/demo/gnuplot directory. While there it wants to read and
# create files. But ordinary users can't create files there. So
# we will create a temporary directory, put in symlinks to the
# gnuplot data files, and run the gnuplot command from there.
# This will allow us to run the gnuplot demo from any directory.
#
# If the environment variable $GNUPLOT_DEMO_SAVE_FILES is set to y,
# then we will save any new files that get created back to the
# current directory. This can also be accomplished by
# "rundemo -save-files".
#
# There are two font files that are not included. Set
# corresponding environment variables for sfrm1000.pfb and
# cmmi10.pfb if running the demo fontfile_latex.dem.
#
# With no arguments we will run the default demo.
# With arguments we will run gnuplot with those arguments.
# One easy way to run the gnuplot demo is "rundemo < /dev/null"
