By default all the output generated by these functions goes to
STDERR. You can override the default filehandler by overriding
C<$Apache::TestTrace::LogFH> with a new filehandler.
+
+When you override this package's global variables, think about
+localizing your local settings, so it won't affect other modules using
+this module in the same run.
