+Using Scheme code to override the stencil for @code{MetronomeMark}
+objects, this example allows the creation of metronome marks which include
+text directions.  The function @code{\tempoChangeMarkup} is called with three
+strings: the text label, note duration, and beats per minute.  To print the
+new metronome mark, this is followed by the standard @code{\tempo} command.

+Unlike text scripts, rehearsal marks cannot be stacked at a particular point
+in a score: only one @code{RehearsalMark} object is created.  Using an
+invisible measure and bar line, an extra rehearsal mark can be added, giving
+the appearance of two marks in the same column.
+
+This method may also prove useful for placing rehearsal marks at both the
+end of one system and the start of the following system.
