>>> show(lilypond_file) # doctest: +SKIP
Makes LilyPond file.
Wraps `music` in LilyPond ``\score`` block.
Adds LilyPond ``\header``, ``\layout``, ``\paper`` and ``\score`` blocks to
LilyPond file.
Defines layout settings for custom ``\TimeSignatureContext``.
(Note that you must create and populate an Abjad context with name
equal to ``'TimeSignatureContext'`` in order for ``\TimeSignatureContext``
layout settings to apply.)
Applies many file, layout and paper settings.
Returns LilyPond file.
