  18   --root   Specifies the repository root. This defaults to "../.." relative
  19            to the script file. This will be correct given the normal location
  20            of the script in "<root>/tools/checklicenses".
  21
  22   --ignore-suppressions  Ignores path-specific license whitelist. Useful when
  23                          trying to remove a suppression/whitelist entry.
  24
  25   tocheck  Specifies the directory, relative to root, to check. This defaults
  26            to "." so it checks everything.
