No problem with linking to it, BUT - I'm not using any latex
packages for the fonts.  I originally found some of them in texlive,
but many of what I'm now using are different versions (for one or
two, the coverage has changed over the years).

Thanks. I find the docs, and indeed trying to read fontforge's tiny
text, hard.  Will have to reinstall it and make another attempt.

Cheers.  I suppose I ought to start by reading up on the OTF font
format.  A quick look at wikipedia suggests the pcap or c2pc tags
(lowercaswe to petite caps, or uppercase to petit caps/0 are part of
what I need.

I think I may be some time!
