<p>
This header defines the type <code class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">math</span><span class="special">::</span><span class="identifier">tuple</span></code>,
the associated free functions <code class="computeroutput"><span class="identifier">ignore</span></code>,
<code class="computeroutput"><span class="identifier">tie</span></code>, <code class="computeroutput"><span class="identifier">make_tuple</span></code>,
<code class="computeroutput"><span class="identifier">get</span></code>, and associated types
<code class="computeroutput"><span class="identifier">tuple_size</span></code> and <code class="computeroutput"><span class="identifier">tuple_element</span></code>.
</p>
<p>
These types and functions are aliases for:
</p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
std::tuple etc when available, otherwise:
</li>
<li class="listitem">
std::tr1::tuple etc when available, otherwise:
</li>
<li class="listitem">
boost::fusion::tuple etc if the compiler supports it, otherwise:
</li>
<li class="listitem">
boost::tuple.
</li>
</ul></div>
<p>
So this <code class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">math</span><span class="special">::</span><span class="identifier">tuple</span></code> is strongly recommended for maximum
portability.
