        `sym <https://github.com/bjodah/sym>`_ provides a unified wrapper to some
        symbolic manipulation libraries in Python. It makes it easy for library authors
        to test their packages against several symbolic manipulation libraries.
        
        Currently the following Python pacakges are available as "backends":
        
            - `SymPy <https://github.com/sympy/sympy>`_
            - `SymEngine <https://github.com/symengine/symengine.py>`_
            - `PySym <https://github.com/bjodah/pysym>`_
            - `SymCXX <https://github.com/bjodah/symcxx>`_
            - `Diofant <https://github.com/diofant/diofant>`_
        
        The capabilities exposed here are those needed by
        
            - `pyodesys <https://pypi.python.org/pypi/pyodesys>`_
            - `pyneqsys <https://pypi.python.org/pypi/pyneqsys>`_
        
        and include:
        
            - Differentiation
            - Numerical evaluation (including "lambdify" support)
        
        see `tests <https://github.com/bjodah/sym/tree/master/sym/tests/>`_ for examples.
        Note that ``pyodesys`` and ``pyneqsys`` also act as test suits for this package.
        
        
        Documentation
        -------------
        Auto-generated API documentation for the latest stable release is found here:
        `<https://bjodah.github.io/sym/latest>`_
        (and the development version for the current master branch is found here:
        `<http://hera.physchem.kth.se/~sym/branches/master/html>`_).
        
        Installation
        ------------
        Simplest way to install sym and its (optional) dependencies is to use pip:
        
        ::
        
           $ pip install --user sym pytest
           $ python -m pytest --pyargs sym
        
        or the `conda package manager <http://conda.pydata.org/docs/>`_:
        
        ::
        
           $ conda install -c bjodah sym pytest
           $ python -m pytest --pyargs sym
        
        Source distribution is available here:
        `<https://pypi.python.org/pypi/sym>`_
        
        Example
        -------
        Differentiation
        
        .. code:: python
        
           >>> from sym import Backend
           >>> be = Backend('pysym')  # just an example, use SymPy rather than pysym
           >>> x, y = map(be.Symbol, 'x y'.split())
           >>> expr = x*y**2 - be.tan(2*x)
           >>> print(expr.diff(x))
           ((y**2) - ((1 + (tan((2*x))**2))*2))
