Re: fretboard diagram - string labels

[Gilles van Eeden]

Hi Carl,

your analysis sounds recognizable. I did notice that a substantial 
amount of code could be reused, e.g. the string parsing and label 
printing code. I will have to look at it again and try to wrap my head 
around lilypond data structures and scheme syntax. Thanks for sharing 
your ideas.

Regards,
Gilles
