% I usually print on letter paper:
#(set-default-paper-size "letter")

paraOne = \markup \justify {
  Many LilyPond experts say that the
  best thing about LilyPond is that it
  handles all layout programmatically.
}

paraTwo = \markup \justify {
  \hspace #3 This block of text contains
  two paragraphs. In both paragraphs, for
  testing purposes, I am using
  abnormally long words.
}

\markup \column {
  \paraOne
  \hspace #0 % needed to prevent collision
  \paraTwo
}
