print """Usage: python checklicenses.py [--root <root>] [tocheck]
--root Specifies the repository root. This defaults to "../.." relative
to the script file. This will be correct given the normal location
of the script in "<root>/tools/checklicenses".
--ignore-suppressions Ignores path-specific license whitelist. Useful when
trying to remove a suppression/whitelist entry.
tocheck Specifies the directory, relative to root, to check. This defaults
to "." so it checks everything.
Examples:
python checklicenses.py
python checklicenses.py --root ~/chromium/src third_party"""
