@section Input structure
The main format of input for LilyPond are text files. By convention,
-these files end with @code{.ly}.
+these files end with @file{.ly}.
@menu
* Structure of a score::
@funindex \book
-All the movements and texts which appear in the same @code{.ly} file
+All the movements and texts which appear in the same @file{.ly} file
will normally be typeset in the form of a single output file.
@example
@node Multiple output files from one input file

-@code{\book} block in the input file, LilyPond will implicitly treat
-the whole file as a single \book block, see @ref{File structure}.

within lilypond-book documents, where you explicitly have to add

or @code{\markup} in the same example. This behavior can be

A more advanced option is to change the definitions of the following
variables in the @code{\paper} block. The init file
-@file{../@/ly/@/titling@/-init@/.ly} lists the default layout.
+@file{../ly/titling-init.ly} lists the default layout.
@table @code
@funindex bookTitleMarkup
The following definition will put the title flush left, and the
composer flush right on a single line.
-@verbatim
-\paper {
- bookTitleMarkup = \markup {
- \fill-line {
+@example
+\paper @{
+ bookTitleMarkup = \markup @{
+ \fill-line @{
\fromproperty #'header:title
\fromproperty #'header:composer
- }
- }
-}
-@end verbatim
+ @}
+ @}
+@}
+@end example
+
+The header and footer are created by the functions
+@code{make-header} and @code{make-footer}, defined in
+@code{\paper}. The default implementations are in
+@file{ly/paper-defaults-init.ly} and
+@file{ly/titling-init.ly}.
+
+This example centers page numbers at the bottom of every page.

Context definitions follow precisely the same syntax as those
within a @code{\layout} block. Translation modules for sound are
called performers. The contexts for MIDI output are defined in
-@file{../@/ly/@/performer@/-init@/.ly},
+@file{../ly/performer-init.ly},
see @rlearning{Other sources of information}.
For example, to remove the effect of dynamics
from the MIDI output, insert the following lines in the
MIDI volume range. The default fractions range from 0.25 for
@notation{ppppp} to 0.95 for @notation{fffff}. The set of dynamic
marks and the associated fractions can be seen in
-@file{../@/scm/@/midi.scm}, see @rlearning{Other sources of information}.
+@file{../scm/midi.scm}, see @rlearning{Other sources of information}.
This set of fractions may be changed or extended by providing a
function which takes a dynamic mark as its argument and returns the
required fraction, and setting
Alternatively, if the whole table of fractions needs to be
redefined, it would be better to use the
@notation{default-dynamic-absolute-volume} procedure in
-@file{../@/scm/@/midi.scm} and the associated table as a model.

The final example in this section shows how this might be done.

LilyPond will, by default, apply a small degree of equalization
to a few instruments. The instruments and the equalization
applied are shown in the table @notation{instrument-equalizer-alist}
