-@node Global layout
-@section Global layout
-The global layout is determined by three factors: the page layout, the
-line breaks, and the spacing. These all influence each other. The
-choice of spacing determines how densely each system of music is set.
-This influences where line breaks are chosen, and thus ultimately, how
-many pages a piece of music takes.
-
-Globally spoken, this procedure happens in three steps: first,
-flexible distances (``springs'') are chosen, based on durations. All
-possible line breaking combinations are tried, and the one with the
-best results -- a layout that has uniform density and requires as
-little stretching or cramping as possible -- is chosen.
-
-After spacing and linebreaking, the systems are distributed across
-pages, taking into account the size of the page, and the size of the
-titles.

-@cindex vertical spacing
-@cindex distance between staves
-@cindex staff distance
-@cindex between staves, distance
-@cindex staves per page
-@cindex space between staves
-
-The height of each system is determined automatically. To prevent
-systems from bumping into each other, some minimum distances are set.
-By changing these, you can put staves closer together, and thus put
-more systems onto one page.
-
-Normally staves are stacked vertically. To make staves maintain a
-distance, their vertical size is padded. This is done with the
-property @code{minimumVerticalExtent}. It takes a pair of numbers, so
-if you want to make it smaller than its default @code{#'(-4 . 4)},
-then you could set
-
-@example
-\set Staff.minimumVerticalExtent = #'(-3 . 3)
-@end example
-
-@noindent
-This sets the vertical size of the current staff to 3 staff spaces on
-either side of the center staff line. The argument of
-@code{minimumVerticalExtent} is interpreted as an interval, where the
-center line is the 0, so the first number is generally negative. The
-staff can be made larger at the bottom by setting it to @code{(-6 . 4)}.
-
-To change the amount of space between systems, use
-@code{betweensystemspace}. A score with only one staff is still
-considered to have systems, so setting @code{betweensystemspace}
-will be much more useful than changing @code{minimumVerticalExtent}.

- betweensystemspace = 10\mm

-@node Vertical spacing of piano staves
-@subsection Vertical spacing of piano staves
-
-The distance between staves of a @internalsref{PianoStaff} cannot be
-computed during formatting. Rather, to make cross-staff beaming work
-correctly, that distance has to be fixed beforehand.
-
-The distance of staves in a @code{PianoStaff} is set with the
-@code{forced-distance} property of the
-@internalsref{VerticalAlignment} object, created in
-@internalsref{PianoStaff}.
-
-It can be adjusted as follows
-@example
-\new PianoStaff \with @{
- \override VerticalAlignment #'forced-distance = #7
-@} @{
- ...
-@}
-@end example
-
-@noindent
-This would bring the staves together at a distance of 7 staff spaces,
-measured from the center line of each staff.
-
-The difference is demonstrated in the following example,
-@lilypond[quote,verbatim]
-\relative <<
- \new PianoStaff \with {
- \override VerticalAlignment #'forced-distance = #7
- } <<
- \new Staff { c1 }

-
-@node Horizontal spacing
-@subsection Horizontal Spacing
-
-The spacing engine translates differences in durations into
-stretchable distances (``springs'') of differring lengths. Longer
-durations get more space, shorter durations get less. The shortest
-durations get a fixed amount of space (which is controlled by
-@code{shortest-duration-space} in the @internalsref{SpacingSpanner} object).
-The longer the duration, the more space it gets: doubling a
-duration adds a fixed amount (this amount is controlled by
-@code{spacing-increment}) of space to the note.
-
-For example, the following piece contains lots of half, quarter, and
-8th notes; the eighth note is followed by 1 note head width (NHW).
-The quarter note is followed by 2 NHW, the half by 3 NHW, etc.
-
-@lilypond[quote,fragment,verbatim,relative=1]
-c2 c4. c8 c4. c8 c4. c8 c8
-c8 c4 c4 c4
-@end lilypond
-
-Normally, @code{spacing-increment} is set to 1.2 staff space, which is
-approximately the width of a note head, and
-@code{shortest-duration-space} is set to 2.0, meaning that the
-shortest note gets 2.4 staff space (2.0 times the
-@code{spacing-increment}) of horizontal space. This space is counted
-from the left edge of the symbol, so the shortest notes are generally
-followed by one NHW of space.
-
-If one would follow the above procedure exactly, then adding a single
-32nd note to a score that uses 8th and 16th notes, would widen up the
-entire score a lot. The shortest note is no longer a 16th, but a 32nd,
-thus adding 1 NHW to every note. To prevent this, the shortest
-duration for spacing is not the shortest note in the score, but rather
-the one which occurs most frequently.
-
-
-The most common shortest duration is determined as follows: in every
-measure, the shortest duration is determined. The most common shortest
-duration is taken as the basis for the spacing, with the stipulation
-that this shortest duration should always be equal to or shorter than
-an 8th note. The shortest duration is printed when you run
-@code{lilypond} with the @code{--verbose} option.
-
-These durations may also be customized. If you set the
-@code{common-shortest-duration} in @internalsref{SpacingSpanner}, then
-this sets the base duration for spacing. The maximum duration for this
-base (normally an 8th), is set through @code{base-shortest-duration}.
-
-@cindex @code{common-shortest-duration}
-@cindex @code{base-shortest-duration}
-@cindex @code{stem-spacing-correction}
-@cindex @code{spacing}
-
-Notes that are even shorter than the common shortest note are
-followed by a space that is proportional to their duration relative to
-the common shortest note. So if we were to add only a few 16th notes
-to the example above, they would be followed by half a NHW:
-
-@lilypond[quote,fragment,verbatim,relative=2]
-c2 c4. c8 c4. c16[ c] c4. c8 c8 c8 c4 c4 c4
-@end lilypond
-
-
-In the introduction (see @ref{Engraving}), it was explained that stem
-directions influence spacing. This is controlled with the
-@code{stem-spacing-correction} property in the
-@internalsref{NoteSpacing}, object. These are generated for every
-@internalsref{Voice} context. The @code{StaffSpacing} object
-(generated in @internalsref{Staff} context) contains the same property
-for controlling the stem/bar line spacing. The following example shows
-these corrections, once with default settings, and once with
-exaggerated corrections:
-
-@lilypond[quote,raggedright]
-{
- c'4 e''4 e'4 b'4 |
- b'4 e''4 b'4 e''4|
- \override Staff.NoteSpacing #'stem-spacing-correction = #1.5

-Spacing is determined on a score wide basis. If you have a score that

-The following definition will put the title flush left, and the
-composer flush right on a single line.

-The major part of this manual is concerned with entering various
-forms of music in LilyPond. However, many music expressions are not
-valid input on their own, for example, a @code{.ly} file containing
-only a note
-@example
-c'4
-@end example
-
-@noindent
-will result in a parsing error. Instead, music should be inside other
-expressions, which may be put in a file by themselves. Such
-expressions are called toplevel expressions. This section enumerates
-them all.
-
-A @code{.ly} file contains any number of toplevel expressions, where a
-toplevel expression is one of the following
-
-@itemize @bullet
-@item
-An output definition, such as @code{\paper}, @code{\midi}, and
-@code{\layout}. Such a definition at the toplevel changes the default
-settings for the block entered.
-
-@item
-A @code{\header} block. This sets the global header block. This
-is the block containing the definitions for book-wide settings, like
-composer, title, etc.
-
-@item
-An @code{\addquote} statement. See @ref{Quoting other voices}
-for more information.
-
-@item
-A @code{\score} block. This score will be collected with other
-toplevel scores, and combined as a single @code{\book}.
-
-This behavior can be changed by setting the variable
-@code{toplevel-score-handler} at toplevel. The default handler is
-defined in the init file @file{scm/@/lily@/.scm}.
-
-@item
-A @code{\book} block logically combines multiple movements
-(i.e., multiple @code{\score} blocks) in one document. A number of
-@code{\scores} creates a single output file, where all movement are
-concatenated.
-
-This behavior can be changed by setting the variable
-@code{toplevel-book-handler} at toplevel. The default handler is
-defined in the init file @file{scm/@/lily@/.scm}.
-
-@item A compound music expression, such as
-@example
-@{ c'4 d' e'2 @}
-@end example
-
-This will add the piece in a @code{\score} and format it in a
-single book together with all other toplevel @code{\score}s and music
-expressions.
-
-This behavior can be changed by setting the variable
-@code{toplevel-music-handler} at toplevel. The default handler is
-defined in the init file @file{scm/@/lily@/.scm}.
-
-@item An indentifier, such as
-@example
-foo = @{ c4 d e d @}
-@end example
-
-This can be used later on in the file by entering @code{\foo}.
-
-@end itemize
-
-The following example shows three things that may be entered at
-toplevel
-
-@example
-\layout @{
- % movements are non-justified by default
- raggedright = ##t
-@}
-
-\header @{
- title = "Do-re-mi"
-@}
-
-@{ c'4 d' e2 @}
-@end example
-
-
-At any point in a file, any of the following lexical instructions can
-be entered:
-
-@itemize @bullet
-@item @code{\version}
-@item @code{\include}
-@item @code{\renameinput}
-@end itemize
