+TODO(epoger): Create a command to update the expected results (in
+self._output_dir_expected) when appropriate.  For now, you should:
+1. examine the results in self.output_dir_actual and make sure they are ok
+2. rm -rf self._output_dir_expected
+3. mv self.output_dir_actual self._output_dir_expected
+Although, if you're using an SVN checkout, this will blow away .svn directories
+within self._output_dir_expected, which wouldn't be good...
