+    By default, module.__version__ is used to get the module version.  To
+    override this, set the module_version_attr keyword argument.  If the
+    attribute of the module to get the version should be called (e.g.,
+    module.version()), then set module_version_attr_call_args to the args such
+    that module.module_version_attr(*module_version_attr_call_args) returns the

+    If the module version is less than min_module_version using the Python <

+
+    You can also specify a minimum Python version by using the

+
+    If the keyword argument warn_not_installed is set to True, the function will

+
+    If the keyword argument warn_old_version is set to True, the function will
+    emit a UserWarning when the library is installed, but cannot be imported
+    because of the min_module_version or min_python_version options.
+
+    Note that because of the way warnings are handled, a warning will be
+    emitted for each module only once.  You can change the default warning
+    behavior by overriding the values of WARN_NOT_INSTALLED and WARN_OLD_VERSION
+    in sympy.external.importtools.  By default, WARN_NOT_INSTALLED is False and
+    WARN_OLD_VERSION is True.
+
+    This function uses __import__() to import the module.  To pass additional
+    options to __import__(), use the import_kwargs keyword argument.  For
+    example, to import a submodule A.B, you must pass a nonempty fromlist option
+    to __import__.  See the docstring of __import__().
+
+    This catches ImportError to determine if the module is not installed.  To
+    catch additional errors, pass them as a tuple to the catch keyword
+    argument.

+
+    Given a Lucas sequence defined by P, Q, returns the kth values for

+
+    Explanation
+    ===========
+
+    The Lucas compositeness test checks whether n is a prime number.
+    The test can be run with arbitrary parameters ``P`` and ``Q``, which also change the performance of the test.
+    So, which parameters are most effective for running the Lucas compositeness test?
+    As an algorithm for determining ``P`` and ``Q``, Selfridge proposed method A [1]_ page 1401
+    (Since two methods were proposed, referred to simply as A and B in the paper,
+    we will refer to one of them as "method A").
+
+    method A fixes ``P = 1``. Then, ``D`` defined by ``D = P**2 - 4Q`` is varied from 5, -7, 9, -11, 13, and so on,
+    with the first ``D`` being ``jacobi(D, n) == -1``. Once ``D`` is determined,
+    ``Q`` is determined to be ``(P**2 - D)//4``.

+PythonMPQ: Rational number type based on Python integers.
+
+This class is intended as a pure Python fallback for when gmpy2 is not
+installed. If gmpy2 is installed then its mpq type will be used instead. The
+mpq type is around 20x faster. We could just use the stdlib Fraction class
+here but that is slower:
+
+    from fractions import Fraction
+    from sympy.external.pythonmpq import PythonMPQ
+    nums = range(1000)
+    dens = range(5, 1005)
+    rats = [Fraction(n, d) for n, d in zip(nums, dens)]
+    sum(rats) # <--- 24 milliseconds
+    rats = [PythonMPQ(n, d) for n, d in zip(nums, dens)]
+    sum(rats) # <---  7 milliseconds
+
+Both mpq and Fraction have some awkward features like the behaviour of
+division with // and %:
+
+    >>> from fractions import Fraction
+    >>> Fraction(2, 3) % Fraction(1, 4)
+    1/6
+
+For the QQ domain we do not want this behaviour because there should be no
+remainder when dividing rational numbers. SymPy does not make use of this
+aspect of mpq when gmpy2 is installed. Since this class is a fallback for that
+case we do not bother implementing e.g. __mod__ so that we can be sure we
+are not using it when gmpy2 is installed either.
