          in <c>HOME/.erlang_tools/pman.opts</c>, where <c>HOME</c> is
          the user's home directory, if such a file exists. Otherwise
          standard trace settings will be used. The return value should

        <p><c>Excluded</c> is a list of module names. If the argument is

          will not be shown by Pman.</p>
