  31         The following templates transform one type to another, based upon some well-defined
  32         rule. Each template has a single member called <code class="computeroutput"><span class="identifier">type</span></code>
  33         that is the result of applying the transformation to the template argument
  34         <code class="computeroutput"><span class="identifier">T</span></code>.
