Everything's current now - the "script 1-5" are the scripts shown during the demonstration. The SSMS report and SSRS report have been added, and my automation script is the current version. The Parse_EN_Messages was updated in November and hasn't changed since.
At the very least, find yourself a testbox and run Script 1 - that shows how it all works, and is a great Proof Of Concept. You could also change the trace group to DDL_SERVER_LEVEL_EVENTS and see all the various things tracked.
And my original blog post on it, which I keep updating:
