Right. But Thierry said that the \endinstallfonts command was the command
that actually did the writing to the files concerned. This appears to be
not the case.

Magic, eh? And there was me thinking it was OzMF->Tools->pltotf->Do all
files. In case you're wondering, I'm not being mindlessly nit-picking.
You get tfms from pl and vpl files. What the fontinst user needs to know
is exactly which files are produced from which input: just saying you get a
tfm doesn't help.

Hmm - but it's not used in \latinfamily, though, which is what I was asking

How do you do that with \latinfamily? I've seen \latinfamily fake small
caps when a suitable afm file containing small caps was available. Can you
say which fount(s) \latinfamily looks for when it's trying to find `real'

Right. The problem is that it's not possible to work out exactly what's
meant unless the distinction is made explicitly. What the novice fontinst
user needs to know is what files you get out for what input, and how those
files relate to what you need to use the founts in LaTeX. I understand the
last bit of that perfectly: pl -> tfm, vpl -> tfm+vf, and fds stay as they
are (with the ui->it substitution added). It's just the correspondance
between input and output that's got me. But... I've got more of an idea
of what's going on now than I did at the start of the week.
