Hi Thomas,

Thank you for your input! This is maybe a silly question, but isn't
there a simple way to hide the following markup code into the Scheme
procedure?

\override #'(line-width . 40) \justify-string

I'd love to keep my 60 etude input files as simple as possible, so if
possible I'd rather write 60 times the shorthand:

\section "The section title comes here. It can be lengthy but it
should gently word wrap if its length exceeds one line."

Best regards,

Olivier
