Re: LilyPond, LilyPond snippets and the GPL

[Karsten Reincke]

Dear Urs;

many thanks for your clever thoughts! You brought up a very seductive argument,
which I therefore will only summarize here for being sure that I've understood 
you
correctly. May I condense your line of argumentation in the following way?

You point out that there could be a function in a GPL licensed snippet which 
only
modifies the apperance of a score. Such a function does not concern the music
itself. And therefore, the copyleft effect is not applied of the music.

Then it seems that you try to generalize your argumentation: Every piece of
LilyPond code describing the music score does not not concern the music, but 
only
the appearance. Hence the, the copyleft effect can not be applied to any results
of the LilyPond compilation process (the pdfs, pngs, ...)

Please tell me, whether I got your point or not. Again, it seems to seductive 
and
I want to consider it a bit longer, before I will answer

best regards karsten
