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

[Valentin Petzel]

Hello Paolo,

Please note that default values are intended to be changed if required. If you 
do not change the default footer in Libre Office Writer you’d be unable to do 
anything but empty footers.

Then note that headers and footers in Lilypond DO have recurring rules, just 
that those rules are much more powerful than what you’d find in a typical text 
writer. But even these so usually have options to have headers and footers 
that are specific to one page.

That being said: Generally the footer markups are what you want to go for when 
placing something at the bottom of the page. With cover and introductory pages 
(where you have full control over the exact page layout) you can instead fill 
the space to push your markup to the bottom. See the appended file as example.

Cheers,
Valentin
