Re: String at the bottom of a cover page without using \markup

[Valentin Petzel]

Hello Paolo,

Yes, that makes sense. This was never meant as some full working 
implementation but just as an example.

Still, what problems did you have with the vertical-fill method? This should 
work quite well for cover pages and such.

Cheers,
Valentin
