Aha! :-))))) So *that's* what all that's about! It's been bothering for
*ages*. Another bit of the jigsaw drops into place.

Coo - thanks. I'll have a look at that file.

Unfortunately, while I've got the hang of the broad flow of things, it's
the nitty-gritty details I'm missing. Do you know which founts
\latinfamily considers as a source of small caps glyphs?

Right - but I don't use the perl scripts and I don't have a directory
structure compatible with anything except my own imagination (it covers
three disc volumes for starters and please don't ask why because I'm not
sure I can remember).

Thanks :-) And thanks very much for trying to answer my questions. I
think I'll be getting somewhere useful soon.
