-LilyPond has no concept of page layout, which makes it difficult to
-reliably choose page breaks in longer pieces.
+@node Page breaking
+@subsection Page breaking
-@node Output details
-@section Output details
+The default page breaking may be overriden by inserting
+@code{\pageBreak} or @code{\noPageBreak} commands. These commands are
+analogous to @code{\break} and @code{\noBreak}. They should be
+inserted with a bar line. These commands force and forbid a page-break
+from happening.
-The default output format is La@TeX{}, which should be run
-through La@TeX{}. Using the option @option{-f}
-(or @option{--format}) other output formats can be selected also, but
- none of them work reliably.
+Page breaks are computed by the @code{page-breaking} function in the
+@code{\bookpaper} block.
-Now the music is output system by system (a `system' is a single line
-from the score, consisting of staves belonging together). From
-@TeX{}'s point of view, a system is an @code{\hbox} which contains a
-lowered @code{\vbox} so that it is centered vertically on the baseline
-of the text. Between systems, @code{\interscoreline} is inserted
-vertically to have stretchable space. The horizontal dimension of the
-@code{\hbox} is given by the @code{linewidth} parameter from
-LilyPond's @code{\paper} block.

-After the last system LilyPond emits a stronger variant of
-@code{\interscoreline} only if the macro
-@code{\lilypondpaperlastpagefill} is not defined (flushing the systems
-to the top of the page). You can avoid that by setting the variable
-@code{lastpagefill} in LilyPond's @code{\paper} block.

-It is possible to fine-tune the vertical offset further by defining the
-macro @code{\lilypondscoreshift}:

+@cindex page size
+@cindex @code{papersize}
+To change the paper size, there are two commands,

-\def\lilypondscoreshift@{0.25\baselineskip@}
+ #(set-default-paper-size "a4")
+ \paper@{
+ #(set-paper-size "a4")

+The second one sets the size of the @code{\paper} block that it is in.

-where @code{\baselineskip} is the distance from one text line to the next.

+@node Page layout
+@subsection Page layout
-@example
-\documentclass@{article@}
+@cindex page layout
+@cindex margins
+@cindex header, page
+@cindex footer, page
-\def\lilypondpaperlastpagefill@{@}
-\lineskip 5pt
-\def\lilypondscoreshift@{0.25\baselineskip@}
+LilyPond will do page layout, setting margins and adding headers and
+footers to each page.
-\begin@{document@}
-This is running text which includes an example music file
-\input@{foo.tex@}
-right here.
-\end@{document@}
-@end example
+The default layout responds to the following settings in the
+@code{\bookpaper} block
-The file @file{foo.tex} has been simply produced with
+@table @code
+@item hsize
+ The width of the page
+@item vsize
+ The height of the page
+@item top-margin
+ Margin between header and top of the page
+@item bottom-margin
+ Margin between footer and bottom of the page
+@item head-sep
+ Distance between top-most music system and the page header
+@item foot-sep
+ Distance between bottom-most music system and the page footer
+@end itemize
+
+The default page header puts the page number and the @code{instrument}
+field from the @code{\header} block on a line.
+
+@cindex copyright
+@cindex tagline
+
+The default footer is empty, except for the first page, where it the
+@code{copyright} field from @code{\header} is inserted, and the last
+page, where @code{tagline} from @code{\header} is added (the default
+tagline is ``Engraved by LilyPond (@var{version})''.
+
+The header and footer are created by the functions @code{make-footer}
+and @code{make-header}, defined in @code{\bookpaper}. The default
+implementations are in @file{scm/page-layout.scm}.
+
+The page layout itself is done by two functions:
+@code{page-music-height} and @code{page-make-stencil}. The former
+tells the line-breaking algorithm how much space can be spent on a
+page, the latter creates the actual page given the system to put on it.
