The 'runner', if provided, must expect the following: cmd : a list of strings representing the command and arguments to execute, as would be passed to e.g. 'subprocess.check_call'. cwd : a string representing the working directory that must be used for the subprocess. Corresponds to the provided source_dir. extra_environ : a dict mapping environment variable names to values which must be set for the subprocess execution.
