 Usage
 -----
 
-subunit-describe-calls will take in a file path via the --subunit parameter
-which contains either a subunit v1 or v2 stream. This is then parsed checking
-for details contained in the file_bytes of the --non-subunit-name parameter
-(the default is pythonlogging which is what Tempest uses to store logs). By
-default the OpenStack Kilo release port defaults (http://bit.ly/22jpF5P)
-are used unless a file is provided via the --ports option. The resulting output
-is dumped in JSON output to the path provided in the --output-file option.
