Right (I think).  So fontinst begins by writing xxx8r.mtx which it also
turns into xxx8r.pl?  And you rely on the dvi driver/printer to encode the
`real' Type 1 fount in 8r encoding?

Now then, obviously you use \transformfont to create the 8r version from
the 8a version.  Am I right in that \transformfont outputs a pl and mtx
file at each step of the way?  So that

\transformfont{fxx8r}{\reencodefont{8r}{\fromafm{fxx8a}}}

will produce fxx8r.mtx, fxx8r.pl, fxx8a.mtx, and fxx8a.pl?

(I think I've got all this straight anyway, but I've been greatly confused
over the last couple of days)
