+"""protector_updater.py: 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. The builds specified 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 Chrome-Protector.py --url=http://chrome-master2.mtv.corp.google. \
+      com/official_builds/ --builds=19.0.1069.0,190.0.1070.0
