"""Tool for preprocessing tests to determine their DEPENDENCIES.
Given an autotest root directory, this tool will aggregate the DEPENDENCIES of
all tests into a single file ready for later consumption by the dynamic suite
infrastructure. ALL DATA MUST BE STORED IN LITERAL TYPES! Dicts, lists,
strings, etc.
Data will be written to stdout (or, optionally a file). Format will be:
{'suite1': {'path/to/test1/control': set(['dep1', 'dep2']),
'path/to/test2/control': set(['dep2', 'dep3'])},
'suite2': {'path/to/test4/control': set(['dep6']),
'path/to/test5/control': set(['dep7', 'dep3'])}}
This is intended for use only with Chrome OS test suits that leverage the
dynamic suite infrastructure in server/cros/
