The drvopt option was an atempt to give some order to a multitude of=20
driver dependant options. What matters to a postscript user to know the=20
tk, xwin, png, tex or other drivers options?
I only didn't remove those driver dependent options from the comon=20
options for "compatibility" reasons, but I was very tempted to do it...

Anyway there are also *program* dependent options, so why not driver=20
dependent options?

Usage:
        lt-x01c [options]

x01c options:
    -locate              Turns on test of API locate function
    -xor                 Turns on test of XOR
    -font number         Selects stroke font set (0 or 1, def:1)
    -save filename       Save plot in color postscript `file'

Make sure you get it right!

At this pace, one would get the one million options award :)
