+"""Script to find list of common images (first beta releases) in Chromeos.
+
+Display information about stable ChromeOS/Chrome versions to be used
+by the team developers. The purpose is to increase team productivity
+by using stable (known and tested) ChromeOS/Chrome versions instead of
+using randomly selected versions. Currently we define as a "stable"
+version the first Beta release in a particular release cycle.
