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