<p>
Generally shouldn't be called directly by users, instead they should use
<code class="computeroutput"><a href="boost/hash.html" title="Struct template hash">boost::hash</a></code>, <code class="computeroutput"><a href="hash_range.html" title="Function hash_range">boost::hash_range</a></code>
or <code class="computeroutput"><a href="hash_combine.html" title="Function template hash_combine">boost::hash_combine</a></code> which
call hash_value without namespace qualification so that overloads
for custom types are found via ADL.
