/** The facilities provided by this header are deprecated.  True assertions
    (that detect broken program logic) should use standard assert (which aborts
    if an assertion fails, and is controlled by the standard NDEBUG macro).
    Logging of warnings (e.g., about malformed input) and traces (e.g., about
    steps taken while executing some protocol) should use the facilities
    provided by sal/log.hxx.

    Because the assertion macro (DBG_ASSERT) has been used for
    true assertions as well as to log warnings, it maps to SAL_WARN instead of
    standard assert.  The warning and error macros (DBG_ASSERTWARNING,
    DBG_WARNING, DBG_WARNING1, ..., DBG_WARNING3, DBG_ERRORFILE) all map to
    SAL_INFO.
