+@subheading Processing the DocBook document
+
+Running @command{lilypond-book} on our @file{.lyxml} file will create a
+valid DocBook document to be further processed with @file{.xml}
+extension. If you use
+@uref{http://@/dblatex@/.sourceforge@/.net@/,dblatex}, it will create a
+PDF file from this document automatically. For HTML (HTML Help,
+JavaHelp etc.) generation you can use the official DocBook XSL
+stylesheets, however, it is possible that you have to make some
+customization for it.

+@node Music fragment options
+@section Music fragment options
+
+In the following, a @q{LilyPond command} refers to any command described
+in the previous sections which is handled by @command{lilypond-book} to
+produce a music snippet. For simplicity, LilyPond commands are only
+shown in @LaTeX{} syntax.
+
+Note that the option string is parsed from left to right; if an option
+occurs multiple times, the last one is taken.
+
+The following options are available for LilyPond commands:
+
+@table @code
+@item staffsize=@var{ht}
+Set staff size to @var{ht}, which is measured in points.
+
+@item ragged-right
+Produce ragged-right lines with natural spacing, i.e.,
+@code{ragged-right = ##t} is added to the LilyPond snippet. This is the
+default for the @code{\lilypond@{@}} command if no @code{line-width}
+option is present. It is also the default for the @code{lilypond}
+environment if the @code{fragment} option is set, and no line width is
+explicitly specified.
+
+@c does this option still exist in lilypond? -jm
+@item packed
+Produce lines with packed spacing, i.e., @code{packed = ##t} is added
+to the LilyPond snippet.
+
+@item line-width
+@itemx line-width=@var{size}\@var{unit}
+Set line width to @var{size}, using @var{unit} as units. @var{unit} is
+one of the following strings: @code{cm}, @code{mm}, @code{in}, or
+@code{pt}. This option affects LilyPond output (this is, the staff
+length of the music snippet), not the text layout.
+
+If used without an argument, set line width to a default value (as
+computed with a heuristic algorithm).
+
+If no @code{line-width} option is given, @command{lilypond-book} tries to
+guess a default for @code{lilypond} environments which don't use the
+@code{ragged-right} option.
