+"""Represents builder bots running layout tests.
+
+This class is used to keep a list of all builder bots running layout tests on
+the Chromium waterfall. There are other waterfalls that run layout tests but
+this list is the one we care about in the context of TestExpectatoins. The
+builders are hard coded in the constructor but can be overridden for unit tests.
