  26 # Unfortunately, the gnuplot demo wants run in the
  27 # /usr/demo/gnuplot directory.  While there it wants to read and
  28 # create files.  But ordinary users can't create files there.  So
  29 # we will create a temporary directory, put in symlinks to the
  30 # gnuplot data files, and run the gnuplot command from there.
  31 # This will allow us to run the gnuplot demo from any directory.
  32 #
  33 # If the environment variable $GNUPLOT_DEMO_SAVE_FILES is set to y,
  34 # then we will save any new files that get created back to the
  35 # current directory.  This can also be accomplished by
  36 # "rundemo -save-files".
  37 #
  38 # There are two font files that are not included.  Set
  39 # corresponding environment variables for sfrm1000.pfb and
  40 # cmmi10.pfb if running the demo fontfile_latex.dem.
  41 #
  42 # With no arguments we will run the default demo.
  43 # With arguments we will run gnuplot with those arguments.
  44 # One easy way to run the gnuplot demo is "rundemo < /dev/null"
