Running mplib is easy enough to document, but that is only a part of
the work: you also have to convert the image to pdf literals, and
that is more work than I would like to put in the manual. Anyway, 
attached is a bunch of definitions I stripped out of context that
will allow you to run mplib in plain tex provided that you also have
context installed (you need mlib-pdf.lua for the PDF conversion)

Best wishes,
