+By using tags, it's possible to use the same music to produce both
+mensural and modern music.  In this snippet, a function @code{menrest}
+is introduced, allowing mensural rests to be pitched as in the
+original, but with modern rests in the standard staff position.  Tags
+are used to produce different types of bar line at the end of the
+music, but tags can also be used where other differences are needed:
+for example using @qq{whole measure rests} (R1, R\\breve etc.) in
+modern music, but normal rests (r1, r\\breve, etc.) in the mensural
+version.  Note that converting mensural music to its modern equivalent
+is usually referred to as @code{transcription}.
