I don't think anybody else uses it. PariPython does not, neither does CLISP,
and neither do we. So feel free to send a patch. Could you post an example of
foreignHandler so that I see how you use it precisely ? (and maybe we could
document the whole mechanism after all this time...).

Since nobody seems to use it, and nobody knew who put it there, I assumed it
was you... I'm removing it then.

If you wish (although the Configure checks for a libgnuplo.a which of course
it never finds...). I had a casual look at this plotgnuplot.c long ago (had
many many other pressing things to do at the time...), and it seemed to me it
needed to be linked with some other library hacked from the GNU package,
right ? And this is definitely not included yet. If I can figure out how it
works, I'll try to include it in one of the next alpha updates.

Everything in there has indeed been (expanded then) included (and is now
documented in the user's manual).
