Hi,

after quite some time this question is on my table again, and I have to 
(and can) be somewhat more concrete about it.

a)
I want to redistribute the Emmentaler .otf fonts in a LaTeX package that 
will be licensed under the LPPL (http://www.latex-project.org/lppl.txt)


b)
I _think_ the Emmentaler fonts are licensed under the OpenFontLicense.
At least that's what I read from the threads Janek reference, and in 
LilyPond's Git repository is a LICENSE.OFL file which strongly indicates 
this.
But in the distributed LilyPond Installation I don't find a reference to 
any license which applies to Emmentaler fonts (Is this a bug?).

The OFL allows redistribution of the fonts without source code but 
strongly suggests to enclose a FONTLOG file. I would gladly supply this 
but unfortunately don't find the relevant information (esp. authors) in 
the LilyPond installation.

So: are my assumptions right? And wouldn't it be necessary to add these 
informations to the LilyPond installation?
