+scripts for theatrical musicals, especially ones under development.  The
+output is formatted to follow generally accepted script style while also
+maintaining a high level of typographic integrity, and includes commands for
+dialog, lyrics, stage directions, music and dance cues, rehearsal marks, and
+more.  It gracefully handles dialog that crosses page breaks, and can generate
+lists of songs and lists of dances in the show.")
