In LaTeX, literal blocks can be customized with the "literal-block-env"
setting. This test file exists to check if the LaTeX writer output compiles
and looks as expected. 

Start with a plain literal block::

  $\sin^2(x)$ and $\cos^2(x)$ equals one:

  \[
     \sin^2(x) + \cos^2(x) = 1 % for all x
  \]

A latex "code-block" (set with "literal-block-env", if syntax
highlight is "none"):

.. code:: latex

  $\sin^2(x)$ and $\cos^2(x)$ equals one:

  \[
     \sin^2(x) + \cos^2(x) = 1 % for all x
  \]

A literal block in a table:

====  ===========  ====
test  ::           test

        \sin^2 x
====  ===========  ====

A literal block in a table with auto-width columns:

.. table::
   :widths: auto

   ====  ===========  ====
   test  ::           test

           \sin^2 x
   ====  ===========  ====

.. note:: A literal block in an admonition::

    \sin^2 x

Parsed literal block with inline markup and leading whitespace:

   standalone hyperlinks (http://www.python.org),
   internal_ and external_ hyperlinks,
   _`internal` hyperlink targets,
   images via substitution references (|example|),

   citation references ([CIT2002]_), and more.

      Here are some explicit interpreted text roles:

   :title:`Docutils`' :emphasis:`standard` :strong:`inline` :literal:`markup`.

   It contains a literal block::
