The files like tfm, afm, pfb,... seem to be found alright by "mtxrun
--script fonts --reload" when they are in the ${HOME}/texmf/fonts/
tree, so I think I can leave them there.
So I should make a sort of copy of "mdugm-math.lgf" and call it
"kpfonts-math.lgf", and put it in
${HOME}/context/tex/texmf-context/tex/context/fonts/.
[Do the same with a copy of "type-imp-mathdesign.mkiv", which
contains: "\loadfontgoodies[mdugm-math]".] Or rather put a typescript
in my document file as explained here:
http://wiki.contextgarden.net/Math_fonts, and insert some
"\loadfontgoodies[kpfonts-math]" in it.
Execute: "context --make en". And that should be it.
What is the "\s!" syntax for, as in "\s!Serif“?
