-    ast
-    ~~~
-
-    The `ast` module helps Python applications to process trees of the Python
-    abstract syntax grammar.  The abstract syntax itself might change with
-    each Python release; this module helps to find out programmatically what
-    the current grammar looks like and allows modifications of it.
-
-    An abstract syntax tree can be generated by passing `ast.PyCF_ONLY_AST` as
-    a flag to the `compile()` builtin function or by using the `parse()`
-    function from this module.  The result will be a tree of objects whose
-    classes all inherit from `ast.AST`.
-
-    A modified abstract syntax tree can be compiled into a Python code object
-    using the built-in `compile()` function.
-
-    Additionally various helper functions are provided that make working with
-    the trees simpler.  The main intention of the helper functions and this
-    module in general is to provide an easy to use interface for libraries
-    that work tightly with the python syntax (template engines for example).

-
-    :param directories: A list of directory names which will be
-     searched for a particular template URI. The URI is appended
-     to each directory and the filesystem checked.
-
-    :param collection_size: Approximate size of the collection used
-     to store templates. If left at its default of ``-1``, the size
-     is unbounded, and a plain Python dictionary is used to
-     relate URI strings to :class:`.Template` instances.
-     Otherwise, a least-recently-used cache object is used which
-     will maintain the size of the collection approximately to
-     the number given.
-
-    :param filesystem_checks: When at its default value of ``True``,
-     each call to :meth:`.TemplateLookup.get_template()` will
-     compare the filesystem last modified time to the time in
-     which an existing :class:`.Template` object was created.
-     This allows the :class:`.TemplateLookup` to regenerate a
-     new :class:`.Template` whenever the original source has
-     been updated. Set this to ``False`` for a very minor
-     performance increase.
-
-    :param modulename_callable: A callable which, when present,
-     is passed the path of the source file as well as the
-     requested URI, and then returns the full path of the
-     generated Python module file. This is used to inject
-     alternate schemes for Python module location. If left at
-     its default of ``None``, the built in system of generation
-     based on ``module_directory`` plus ``uri`` is used.
-
-    All other keyword parameters available for
-    :class:`.Template` are mirrored here. When new
-    :class:`.Template` objects are created, the keywords
-    established with this :class:`.TemplateLookup` are passed on
-    to each new :class:`.Template`.

-    as well as the source code of the
-    generated Python module (i.e. the :attr:`.code` attribute),
-    as well as a reference to an actual Python module.
-
-    :class:`.Template` is constructed using either a literal string
-    representing the template text, or a filename representing a filesystem
-    path to a source file.
-
-    :param text: textual template source.  This argument is mutually
-     exclusive versus the ``filename`` parameter.
-
-    :param filename: filename of the source template.  This argument is
-     mutually exclusive versus the ``text`` parameter.
-
-    :param buffer_filters: string list of filters to be applied
-     to the output of ``%def``\ s which are buffered, cached, or otherwise
-     filtered, after all filters
-     defined with the ``%def`` itself have been applied. Allows the
-     creation of default expression filters that let the output
-     of return-valued ``%def``\ s "opt out" of that filtering via
-     passing special attributes or objects.
-
-    :param bytestring_passthrough: When ``True``, and ``output_encoding`` is
-     set to ``None``, and :meth:`.Template.render` is used to render,
-     the `StringIO` or `cStringIO` buffer will be used instead of the
-     default "fast" buffer.   This allows raw bytestrings in the
-     output stream, such as in expressions, to pass straight
-     through to the buffer.  This flag is forced
-     to ``True`` if ``disable_unicode`` is also configured.
-
-     .. versionadded:: 0.4
-        Added to provide the same behavior as that of the previous series.
-
-    :param cache_args: Dictionary of cache configuration arguments that
-     will be passed to the :class:`.CacheImpl`.   See :ref:`caching_toplevel`.
-
-    :param cache_dir:
-
-     .. deprecated:: 0.6
-        Use the ``'dir'`` argument in the ``cache_args`` dictionary.
-        See :ref:`caching_toplevel`.
-
-    :param cache_enabled: Boolean flag which enables caching of this
-     template.  See :ref:`caching_toplevel`.
-
-    :param cache_impl: String name of a :class:`.CacheImpl` caching
-     implementation to use.   Defaults to ``'beaker'``.
-
-    :param cache_type:
-
-     .. deprecated:: 0.6
-        Use the ``'type'`` argument in the ``cache_args`` dictionary.
-        See :ref:`caching_toplevel`.
-

-
-     .. deprecated:: 0.6
-        Use the ``'url'`` argument in the ``cache_args`` dictionary.

-     be applied to all expressions.  See :ref:`filtering_default_filters`.
-
-    :param disable_unicode: Disables all awareness of Python Unicode
-     objects.  See :ref:`unicode_disabled`.
-
-    :param enable_loop: When ``True``, enable the ``loop`` context variable.
-     This can be set to ``False`` to support templates that may
-     be making usage of the name "``loop``".   Individual templates can
-     re-enable the "loop" context by placing the directive
-     ``enable_loop="True"`` inside the ``<%page>`` tag -- see
-     :ref:`migrating_loop`.

-    :param encoding_errors: Error parameter passed to ``encode()`` when
-     string encoding is performed. See :ref:`usage_unicode`.
-
-    :param error_handler: Python callable which is called whenever
-     compile or runtime exceptions occur. The callable is passed
-     the current context as well as the exception. If the
-     callable returns ``True``, the exception is considered to
-     be handled, else it is re-raised after the function
-     completes. Is used to provide custom error-rendering
-     functions.
-
-    :param format_exceptions: if ``True``, exceptions which occur during
-     the render phase of this template will be caught and
-     formatted into an HTML error page, which then becomes the
-     rendered result of the :meth:`.render` call. Otherwise,
-     runtime exceptions are propagated outwards.
-
-    :param imports: String list of Python statements, typically individual
-     "import" lines, which will be placed into the module level
-     preamble of all generated Python modules. See the example
-     in :ref:`filtering_default_filters`.
-
-    :param future_imports: String list of names to import from `__future__`.
-     These will be concatenated into a comma-separated string and inserted
-     into the beginning of the template, e.g. ``futures_imports=['FOO',
-     'BAR']`` results in ``from __future__ import FOO, BAR``.  If you're
-     interested in using features like the new division operator, you must
-     use future_imports to convey that to the renderer, as otherwise the
-     import will not appear as the first executed statement in the generated
-     code and will therefore not have the desired effect.
-
-    :param input_encoding: Encoding of the template's source code.  Can
-     be used in lieu of the coding comment. See
-     :ref:`usage_unicode` as well as :ref:`unicode_toplevel` for
-     details on source encoding.
-
-    :param lookup: a :class:`.TemplateLookup` instance that will be used
-     for all file lookups via the ``<%namespace>``,
-     ``<%include>``, and ``<%inherit>`` tags. See
-     :ref:`usage_templatelookup`.
-
-    :param module_directory: Filesystem location where generated
-     Python module files will be placed.
-
-    :param module_filename: Overrides the filename of the generated
-     Python module file. For advanced usage only.
-
-    :param module_writer: A callable which overrides how the Python
-     module is written entirely.  The callable is passed the
-     encoded source content of the module and the destination
-     path to be written to.   The default behavior of module writing
-     uses a tempfile in conjunction with a file move in order
-     to make the operation atomic.   So a user-defined module
-     writing function that mimics the default behavior would be:
-
-     .. sourcecode:: python
-
-         import tempfile
-         import os
-         import shutil
-
-         def module_writer(source, outputpath):
-             (dest, name) = \\
-                 tempfile.mkstemp(
-                     dir=os.path.dirname(outputpath)
-                 )
-
-             os.write(dest, source)
-             os.close(dest)
-             shutil.move(name, outputpath)
-
-         from mako.template import Template
-         mytemplate = Template(
-                         filename="index.html",
-                         module_directory="/path/to/modules",
-                         module_writer=module_writer
-                     )
-
-     The function is provided for unusual configurations where
-     certain platform-specific permissions or other special
-     steps are needed.
-
-    :param output_encoding: The encoding to use when :meth:`.render`
-     is called.
-     See :ref:`usage_unicode` as well as :ref:`unicode_toplevel`.
-
-    :param preprocessor: Python callable which will be passed
-     the full template source before it is parsed. The return
-     result of the callable will be used as the template source
-     code.
-
-    :param lexer_cls: A :class:`.Lexer` class used to parse
-     the template.   The :class:`.Lexer` class is used by
-     default.
-
-     .. versionadded:: 0.7.4
-
-    :param strict_undefined: Replaces the automatic usage of
-     ``UNDEFINED`` for any undeclared variables not located in
-     the :class:`.Context` with an immediate raise of
-     ``NameError``. The advantage is immediate reporting of
-     missing variables which include the name.
-
-     .. versionadded:: 0.3.6
-
-    :param uri: string URI or other identifier for this template.
-     If not provided, the ``uri`` is generated from the filesystem
-     path, or from the in-memory identity of a non-file-based
-     template. The primary usage of the ``uri`` is to provide a key
-     within :class:`.TemplateLookup`, as well as to generate the
-     file path of the generated Python module file, if
-     ``module_directory`` is specified.
