[h4 Synopsis]

``
#include <boost/math/tools/tuple.hpp>
``

[h4 Description]

This header defines the type `boost::math::tuple`, 
the associated free functions `ignore`, `tie`, `make_tuple`, `get`, 
and associated types `tuple_size` and `tuple_element`.

These types and functions are aliases for:

* std::tuple etc when available, otherwise:
* std::tr1::tuple etc when available, otherwise:
* boost::fusion::tuple etc if the compiler supports it, otherwise:
* boost::tuple.

So this `boost::math::tuple` is strongly recommended for maximum portability.
