clearOnAppStop - where does it belong? Application.xml

I see the documentation about using clearOnAppStop, but its not clear what file its supposed to be put into!?

Does it belong in Application.xml?  Event.xml?  httpd.conf?  main.asc?  In the HTML of the player?????

Sorry, I'm far from an expert on all of this stuff.  I have been able to successfully publish multibitrate HDS and HLS, but I'd like the stream files to go away.

Update: I added the recommended configuration to the Application.xml file:

<Application>

...

    <ScriptEngine>

        <ApplicationObject>

            <config>

                <clearOnAppStop>true</clearOnAppStop>

            </config>

        </ApplicationObject>

    </ScriptEngine>

...

</Application>

After 600 seconds of inactivity, the stream files, and the directory they were in, were removed.  I found helpful info about this here: http://forums.adobe.com/thread/755484

Also, I'm assuming that this setting has no affect on the livepkgr/events/_definst_/<event>/*.stream files?

Is there a way to clean up the events?  I'm creating a unique event and stream names for each event, and when the event is over, it will never be used again.

Update: I still haven't found an automatic way to remove the event files.

Thanks!
