    or a static renderer), render the value (or set of values) present
    in ``value``. Return the result of the renderer's ``__call__``
    method (usually a string or Unicode).

    If the ``renderer_name`` refers to a file on disk, such as when the
    renderer is a template, it's usually best to supply the name as an
    :term:`asset specification`
    (e.g. ``packagename:path/to/template.pt``).

    You may supply a relative asset spec as ``renderer_name``.  If
    the ``package`` argument is supplied, a relative renderer path
    will be converted to an absolute asset specification by
    combining the package ``package`` with the relative
    asset specification ``renderer_name``.  If ``package``
    is ``None`` (the default), the package name of the *caller* of
    this function will be used as the package.

    The ``value`` provided will be supplied as the input to the
    renderer.  Usually, for template renderings, this should be a
    dictionary.  For other renderers, this will need to be whatever
    sort of value the renderer expects.

    The 'system' values supplied to the renderer will include a basic set of
    top-level system names, such as ``request``, ``context``,
    ``renderer_name``, and ``view``.  See :ref:`renderer_system_values` for
    the full list.  If :term:`renderer globals` have been specified, these
    will also be used to augment the value.

    Supply a ``request`` parameter in order to provide the renderer
    with the most correct 'system' values (``request`` and ``context``
    in particular).

    .. note:: Calling :meth:`pyramid.Request.static_url` can be used to
              achieve the same result as :func:`pyramid.url.static_url`.

        static_url('mypackage:static/foo.css', request) =>

    The ``path`` argument points at a file or directory on disk which
    a URL should be generated for.  The ``path`` may be either a
    relative path (e.g. ``static/foo.css``) or a :term:`asset
    specification` (e.g. ``mypackage:static/foo.css``).  A ``path``
    may not be an absolute filesystem path (a :exc:`ValueError` will
    be raised if this function is supplied with an absolute path).

    The ``request`` argument should be a :term:`request` object.

    The purpose of the ``**kw`` argument is the same as the purpose of
    the :func:`pyramid.url.route_url` ``**kw`` argument.  See the
    documentation for that function to understand the arguments which
    you can provide to it.  However, typically, you don't need to pass
    anything as ``*kw`` when generating a static asset URL.

    This function raises a :exc:`ValueError` if a static view
    definition cannot be found which matches the path specification.
