"""Tool for preprocessing control files to build a suite to control files map.
Given an autotest root directory, this tool will bucket tests accroding to
their suite.Data will be written to stdout (or, optionally a file), eg:
{'suite1': ['path/to/test1/control', 'path/to/test2/control'],
'suite2': ['path/to/test4/control', 'path/to/test5/control']}
This is intended for use only with Chrome OS test suites that leverage the
dynamic suite infrastructure in server/cros/ It is invoked
at build time to generate said suite to control files map, which dynamic_suite
consults at run time to determine which tests belong to a suite.
