This class used to output log statements from within the log4cxx package.

sometimes useful for the user to learn about what log4cxx is
doing. You can enable log4cxx internal logging by calling the
<b>#setInternalDebugging</b> method.
<p>All log4cxx internal debug calls go to standard output
where as internal error messages are sent to
standard error output. All internal messages are prepended with
the string "log4cxx: ".
