+"""Runs Protector updater tests using two Chrome builds.
+
+Test requires two arguments: build url and chrome versions to be used, rest of 
+the arguments are optional. Specified builds are sorted before installation
+begins, meaning lowest version of Chrome gets installed first and then Chrome
+is updated using the next, higher version of Chrome. Install and Update, which
+are both handled by the base class, return a pyauto.PyUITest object. PyUITest
+object can then be used to run updater tests.
+
+Example:  
+    $ python protector_updater.py --url=<URL> --builds=19.0.1069.0,19.0.1070.0
