Re: kpfonts, math, type 1 font

[Elspeth McGullicuddy <elspethmcgullicuddy@gmail.com>]

As for the first point: buggy afm files, I've tried "generate font"
from "fontforge" interface:
Even though I've let fontforge proceed to many auto-corrections, the
output produced
and then installed seems not to fit the bill: nothing is showing.

I reckon I've learned as much as can be done in one go:
=> I temporarily give up.

Nevertheless if one have information about the vector I wrote for bold Greek:
why that didn't work, I'll will gladly have it.
