Markups attached to a multi-measure rest will be centered above or
below it. Long markups attached to multi-measure rests do not cause
the measure to expand. To expand a multi-measure rest to fit the markup,
use a spacer rest with an attached markup before the multi-measure rest:
-@c -- music is somewhat compressed vertically. I thought it
-@c was good because the emphasis is not on the content
-@c of the markup, but on the place the markup was attached -cs

@cindex grace notes, in anacruses
-This command does not take into account grace notes at the start
-of the music. If the pick-up starts with one or more grace
-notes, then the @code{\partial} should follow the grace note(s):
-
-@lilypond[verbatim,quote,ragged-right,relative,fragment]
-\grace f16
-\partial 4
-g4
-a2 g2
-@end lilypond
-
The @code{\partial} command is intended to be used only at the
beginning of a piece. If you use it after the beginning, some
odd warnings may occur.
Polymetric notation is supported, either explicitly or through
clever use of markup features.
-@c Each of these examples uses \set or \override, and therefore
-@c by policy should be converted to a snippet.
-@c Do we want to have a section with a very brief (two-line

-Two special forms of the @code{\grace} command exist.

-is denoted by a slurred small note with a slashed stem. The
-@emph{appoggiatura}, a grace note that takes a fixed fraction of the
-main note, is denoted as a slurred note in small print without
