-      Abjad helps composers build up complex pieces of music notation in
-      iterative and incremental ways. Use Abjad to create a symbolic
-      representation of all the notes, rests, chords, tuplets, beams and slurs
-      in any score. Because Abjad extends the Python programming language, you
-      can use Abjad to make systematic changes to music as you work. Because
-      Abjad wraps the LilyPond music notation package, you can use Abjad to
-      control the typographic detail of symbols on the page.
