* <dt><tt>logToStdErr</tt></dt>
* <dd>When it is set true, the output stream will be
* <code>std::cerr</code> instead of <code>std::cout</code>.</dd>
*
* <dt><tt>ImmediateFlush</tt></dt>
* <dd>When it is set true, output stream will be flushed after
* each appended event.</dd>
*
* <dt><tt>Locale</tt></dt>
* <dd>This property specifies a locale name that will be imbued
* into output stream. Locale can be specified either by system
* specific locale name, e.g., <tt>en_US.UTF-8</tt>, or by one of
* four recognized keywords: <tt>GLOBAL</tt>, <tt>DEFAULT</tt>
* (which is an alias for <tt>GLOBAL</tt>), <tt>USER</tt> and
* <tt>CLASSIC</tt>. When specified locale is not available,
* <tt>GLOBAL</tt> is used instead. It is possible to register
* additional locale keywords by registering an instance of
* <code>spi::LocaleFactory</code> in
* <code>spi::LocaleFactoryRegistry</code>.
* \sa spi::getLocaleFactoryRegistry().
*
* Note: if <tt>Locale</tt> is set, <tt>ImmediateFlush</tt> will
* be set to true automatically.
