+"""Simple command-line sample for Google Coordinate.
+
+Pulls a list of jobs, creates a job and marks a job complete for a given
+Coordinate team. Client IDs for installed applications are created in the
+Google API Console. See the documentation for more information:
+
+   https://developers.google.com/console/help/#WhatIsKey
+
+Usage:
+  $ python coordinate.py -t teamId
+
+You can also get help on all the command-line flags the program understands
+by running:
+
+  $ python coordinate.py --help
+
+To get detailed log output run:
+
+  $ python coordinate.py -t teamId --logging_level=DEBUG
