      All exception objects are defined in one of the standard header
      files: <code class="filename">exception</code>,
      <code class="filename">stdexcept</code>, <code class="filename">new</code>, and
      <code class="filename">typeinfo</code>.
    </p><p>
      The base exception object is <code class="classname">exception</code>,
      located in <code class="filename">exception</code>. This object has no
      <code class="classname">string</code> member.
    </p><p>
      Derived from this are several classes that may have a
      <code class="classname">string</code> member: a full hierarchy can be
      found in the <a class="ulink" href="http://gcc.gnu.org/onlinedocs/libstdc++/latest-doxygen/a00233.html" target="_top">source documentation</a>.
