[NTG-context] Using MetaPost to create fonts

Hi! I have the impression that I did see that MetaPost can be used to create full fonts and not only pictures. (In fact to keep the potential of METAFONT, but extending it to OpenType /PostScript/TrueType (??) fonts.) I even think there was mention about Perl in this respect. Did I dream or not (yes I start to dream about ConTeXt and MetaPost !!!). Could you point me to the right direction and provide links and/or email address of the persons who are involved? Thanks, -- Alain
