font-family

[Walt North]

I don't think I'm understanding font-family correctly.  And the 
documentation is not gelling with me.

I see a large number of font family names when I run the display fonts 
command.

But only roman, sans, and typewriter seem to have any affect when I set 
the font-family in the layout.

So far neither the lilypond documentation nor any any google searches is 
helping me understand how font families are set other then the three 
that seem to work. I'm hoping someone can help make it click for me.
