<h2><a name="single">Single Bit-Mask Class Template</a></h2>

<p>The <code>boost::high_bit_mask_t</code> class template provides
constants for bit masks representing the bit at a certain position.  The
masks are equivalent to the value 2<sup><code>Bit</code></sup>, where
<code>Bit</code> is the template parameter.  The bit position must be a
nonnegative number from zero to <i>Max</i>, where <dfn>Max</dfn> is one
less than the number of bits supported by the larges
