Re: set-global-staff-size from inside Scheme function

[Jan-Peter Voigt]

Hi Urs,

the last statement the include returns is not music:
#(ly:set-option 'preview #t)
so the parser complains.
Those warnings can be avoided with void-functions, which wrap the statement.

(A bit in a hurry, so no example for noew ;) )

Cheers, Jan-Peter
