The mystery is: where is this list?  I have lots of information which will
probably help me produce such a list myself, but I've not seen a clear list
of exactly how fontinst selects a fount to fake (say) an sc fount.  I've
seen a list of fd file substitutions which is beginning to make more sense.

Ah....  That explains it.  I don't when I'm using that sort of phrase.

I've run \latinfamily on a set of afms that included old-style numerals and
the result did not include a fount with old style numerals:

FontName CaslonBookBE-RegularExp
FullName Caslon Book BE Regular Expert
FamilyName Caslon Book BE

afm name: pckr8x.afm

Instruction to fontinst: \latinfamily{pck}{}

Result: a set of pl and vpl files none of which used any glyphs from
pckr8x.afm.  I've searched the log file for occurances of pckr8x, and there
are no occurances of 8x anywhere in it.

Clearly, fontinst did not `just do it'.  What do you have to do to get
fontinst to use expert encoded founts?  Is it just adding an `x' or `9'
onto the end of the family name in \latinfamily?

Ta muchly
