Where do the Century Font files come from?

[Urs Liska]

Hi,

I'm wondering where the Century Font files come from that land in mf/out 
and out/share/lilypond/current/fonts when building lily.

I don't find any sources, and trying to understand mf/GNUmakefile I get 
the impression that they are somehow pulled from the latex installation 
that is part of the LilyPond build dependencies.

I'm asking because I'd like to have an estimate on the amount of work or 
complexity needed to add font faces to Century, a condensed version in 
particular.

The width of LilyPond's default text font is the major issue for using 
it in a vocal music style sheet for me. Once I started a survey but 
didn't find a suitable free replacement font. While there were several 
fonts that were aesthetically quite suitable for a LilyPond engraving 
stylesheet I didn't find any that would be suitable for typesetting 
dense lyrics. So unfortunately I'm still tied to use the commercial 
Minion font which has _lots_ of faces, with the particular advantage of 
allowing to combine for example condensed with medium _or_ semibold.

If Century came from metafont source it should be in theory be 
comparably simple to add a narrower variant, isn't it?

But that's probably useless hope?
