+"""Simple event test for the HTML5 media tag.
+
+This PyAuto powered script plays media (video or audio) files using the HTML5
+tag embedded in an HTML file (specified in the GetPlayerHTMLFileName() method)
+and asserts proper event occurrence relating to track (caption). The parameters
+needed to run this test are passed in the form of environment variables
+(such as the number of runs). Media_perf_runner.py is used for generating
+these variables (PyAuto does not support direct parameters).
