<code class="literal">boost.heap</code> is an implementation of priority queues. Priority
queues are queue data structures, that order their elements by a priority.
The STL provides a single template class <code class="literal">std::priority_queue</code>,
which only provides a limited functionality. To overcome these limitations,
<code class="literal">boost.heap</code> implements <a class="link" href="heap/data_structures.html" title="Data Structures">data
structures</a> with more functionality and different performance characteristics.
Especially, it deals with additional aspects:

<li class="listitem">
<span class="bold"><strong>Mutability</strong></span>: The priority of heap elements
can be modified.
</li>
<li class="listitem">
<span class="bold"><strong>Iterators</strong></span>: Heaps provide iterators to
iterate all elements.

<span class="bold"><strong>Mergable</strong></span>: While all heaps can be merged,
some can be merged efficiently.
