-    Label a test as 'slow'.
-
-    The exact definition of a slow test is obviously both subjective and
-    hardware-dependent, but in general any individual test that requires more
-    than a second or two should be labeled as slow (the whole suite consists of
-    thousands of tests, so even a second is significant).
-
-    Parameters
-    ----------
-    t : callable
-        The test to label as slow.
-
-    Returns
-    -------
-    t : callable
-        The decorated test `t`.
-
-    Examples
-    --------
-    The `numpy.testing` module includes ``import decorators as dec``.
-    A test can be decorated as slow like this::
-
-      from numpy.testing import *
-
-      @dec.slow
-      def test_big(self):
-          print 'Big, slow test'

-
-    t.slow = True
-    return t

-def setastest(tf=True):
-    """
-    Signals to nose that this function is or is not a test.
-
-    Parameters
-    ----------
-    tf : bool
-        If True, specifies that the decorated callable is a test.
-        If False, specifies that the decorated callable is not a test.
-        Default is True.
-
-    Notes
-    -----
-    This decorator can't use the nose namespace, because it can be
-    called from a non-test module. See also ``istest`` and ``nottest`` in
-    ``nose.tools``.
-
-    Examples
-    --------
-    `setastest` can be used in the following way::
-
-      from numpy.testing.decorators import setastest
-
-      @setastest(False)
-      def func_with_test_in_name(arg1, arg2):
-          pass

-    def set_test(t):
-        t.__test__ = tf
-        return t

-    Filter deprecation warnings while running the test suite.
-
-    This decorator can be used to filter DeprecationWarning's, to avoid
-    printing them during the test suite run, while checking that the test
-    actually raises a DeprecationWarning.
-
-    Parameters
-    ----------
-    conditional : bool or callable, optional
-        Flag to determine whether to mark test as deprecated or not. If the
-        condition is a callable, it is used at runtime to dynamically make the
-        decision. Default is True.
