What you actually need is a cff2afm program, however, this doesn't
exist...
BUT: You can use FontForge to load any font, then converting it to a
Type1 font and an AFM file. I just tried it for `Linux Biolinum'
(from the Libertine family): The AFM file has a whopping size of
2.6MByte, with 2479 glyph metrics and 109131 kernpairs...
BTW, this should work on any platform since FontForge can be
controlled by two scripting languages (either a native one or with a
Python interface) which doesn't use a GUI.
