-@subsection Scheme data types
-
-Scheme is used to glue together different program modules. To aid this
-glue function, many LilyPond specific object types can be passed as
-Scheme value.
-
-The following list are all LilyPond specific types, that
-can exist during parsing:
-@table @code
-@item Duration
-@item Input
-@item Moment
-@item Music
-@item Event
-In C++ terms, an @code{Event} is a subtype of @code{Music}. However,
-both have different functions in the syntax.
-@item Music_output_def
-@item Pitch
-@item Score
-@item Translator_def
-@end table
-
-
-During a run, transient objects are also created and destroyed.
-
-@table @code
-@item Grob: short for `Graphical object'.
-@item Scheme_hash_table
-@item Music_iterator
-
-@item Stencil: Device-independent page output object,
-including dimensions.
-
-@item Spring_smob
-
-@item Translator: An object that produces audio objects or Grobs.
-It may be accessed with @code{\applyoutput}.
-
-@item Font_metric: An object representing a font.
-@end table
-
-Many functions are defined to manipulate these data structures. They
-are all listed and documented in the internals manual, see
-@internalsref{All scheme functions}.

@section Output details
-LilyPond's default output format is @TeX{}. Using the option @option{-f}
+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
currently none of them work reliably.
-At the beginning of the output file, various global parameters are defined.
-It also contains a large @code{\special} call to define PostScript routines
-to draw items not representable with @TeX{}, mainly slurs and ties. A DVI
-driver must be able to understand such embedded PostScript, or the output
-will be rendered incompletely.
-
-Then the file @file{lilyponddefs.tex} is loaded to define the macros used
-in the code which follows. @file{lilyponddefs.tex} includes various other
-files, partially depending on the global parameters.

Now the music is output system by system (a `system' consists of all

The horizontal dimension of the @code{\hbox} is given by the

After the last system LilyPond emits a stronger variant of
@code{\interscoreline} only if the macro

where @code{\baselineskip} is the distance from one text line to the next.
-The code produced by LilyPond should be run through La@TeX{}, not
-plain @TeX{}.
-
Here an example how to embed a small LilyPond file @code{foo.ly} into
running La@TeX{} text without using the @code{lilypond-book} script
(@pxref{lilypond-book manual}):
The file @file{foo.tex} has been simply produced with
@example
-lilypond foo.ly
+ lilypond-bin foo.ly
@end example
-It is important to set the @code{indent} parameter to zero in the
-@code{\paper} block of @file{foo.ly}.
-
The call to @code{\lineskip} assures that there is enough vertical space
between the LilyPond box and the surrounding text lines.
