[pdftex] how to include literal commands into vpl files

[Ulrich Dirr]

I've tried this but it didn't work.

Maybe there's something wrong with my virtual font setup. I
put the tfm and vf files in the texmf tree and rebuilt the
database. In the source I put (for testing) a
\font\virtualfontname=virtualfont at 16dd and in the map
file something like "tfmrealfont Postscriptname
<realfont.pfb".

?
