 The most commonly used functionality of gnuplot is supported directly by the
-script. Anything not directly supported can still be done with the
-C<--extracmds> and C<--curvestyle> options. Arbitrary gnuplot commands can be
-passed in with C<--extracmds>. For example, to turn off the grid, pass in
-C<--extracmds 'unset grid'>. As many of these options as needed can be passed
-in. To add arbitrary curve styles, use C<--curvestyle curveID extrastyle>. Pass
-these more than once to affect more than one curve. To apply an extra style to
-I<all> the curves that lack an explicit C<--curvestyle>, pass in
-C<--curvestyleall extrastyle>.
