Could someone please explain to me the sordid details of font families
(in Plain TeX).  Or alternatively, has anyone managed to make Adobe
``expert'' fonts work with Tetures (for the Macintosh)?

What I would like to do, for example, is use Adobe Garamond and Adobe
Garamond Expert within TeX without too much trouble.  That is, I would
like ligatures other than `fi' and `fl' to be automatically chosen from
the expert font (e.g., ff, ffi, ffl), without forcing me to special case
these within the text.  Similarly, it would be nice to take advantage of
other features such as italic, bold, titling caps, small caps, etc.,
without getting into too much of the guts of TeX.  I have managed to get
\it and \bf to do what I want, more or less painlessly, but I would
still appreciate someone explaining to me more of the fine points of
TeX font families than is in the TeXbook.

Thanks for any help anyone can supply.
