Can you explain what this means?

Are you saying that when you execute a \latinfamily command, fontinst
(eventually) looks for:

pckm8a.afm then
pckm8r.afm them


And what if it finds pckm8a.afm?  pckm8r.afm?  pckm8r.mtx?

I'm afraid I'm still confused.  What would cause fontinst to do this

What does it do if it finds this?

>* if checks if pckm8r.mtx exists,

What does it do if it finds this?

Do you mean that the command above tells fontinst to look for pckm8r.mtx,
and if it fails to find that, it'll look for pckm8r.afm and convert it into
an mtx file, and that this procedure is followed by fontinst at *any* time
it's looking for an mtx file?

I'll take your word for it :-)
