| 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... |
