I've got a reply off list suggesting to use mplib. That sounds
good, but I have some problems getting mplib source code, because
I cannot find the header files in TeX Live or ConTeXt Beta.

The only place where I have found mplib.h is in

trunk/branches/pweb/src/texk/web2c/mpdir

from

svn checkout https://foundry.supelec.fr/svn/metapost trunk

However, compiling a program results in 'mpd.h' not found. This
may depend on the fact that the checkout eventually times out,
leaving me with a partial download (I've tried a couple of times).

Is there a smaller download?
