I use a lot of overhead slides in my econ teaching
(thanks to gpresent) which often contain math
symbols. The default math symbols are not Bold
(in either S or SS). I have found and installed (thanks
to the recent advice on doing this) a bold italics
math font MathDesign-UT-Bold-Italic-MathItalic-10
Now I want geqn to use the symbols from this fault
instead of from SS. I suppose I could just rename
MDUTBIMI (my name for the new font) SS in
font/devps, but isn't there a more elegant way to do
it in a document? (I don't always want to use the
new font in geqn.)
