[Groff] Vgrind and vfontedpr

[Pierre-Jean]

Hello alls,

You maybe remember that vgrind is an old pre-processor for
troff that colorize source code. It's a shell script that
call a C progamm named vfontedpr.

I'm trying to understand what those names means. In french,
to grind means « grincer » and « mouliner ». Does that mean
that vgrind does a difficult job?

It seems that vfontedpr has something to do with « font »,
since it adds font definition inside code. Does that mean
that within vfontedpr, a programm ( « pr » ) is « fonted » ?

Last but not least, what's the meaning of that « v » ? Is it
for « virtual » ?

As you can see, these questions are absolutely essentials. I
hope that a good english speaker could explain me what does
that mean.

Cheers,

Pierre-Jean.
