...one of the most highly
regarded and expertly designed C++ library projects in the
world.

While many test log configuration tasks can be performed at runtime using
predefined framework parameters, the Unit Test Framework
provides a compile time interface as well. The interface gives you full power
over what, where and how to log. The interface of the logger is provided
by singleton class boost::unit_test::unit_test_log_t
and is accessible through local file scope reference to single instance of
this class
boost::unit_test::unit_test_log
In order to install customization of the logger, the Unit Test
Framework provides the BOOST_TEST_GLOBAL_CONFIGURATION
facility that acts in a similar fashion to a global fixture.
