⌂ Inserting large plain text sections, as independent \markup blocks

LilyPond can handle text almost as well as music notation: in a \book block, you can enter different \score blocks, but also independent \markup sections. This snippet also demonstrates some interesting text formatting features such as \justify-string or \wordwrap-string (do not forget the # character when using them). The \fill-line command produces centered text, and you can define margins using \override #'(line-width . X), where X is the width in staff spaces.
