# 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"
