+  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".
+
+  --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.

+  python checklicenses.py
+  python checklicenses.py --root ~/chromium/src third_party"""
