You'll need to update this path.

The below old webcore_dir will be used.

We've got some logic for this in htmlrenamer.py - e.g., search for
WebkitMediaSource.  We drop that in favor of MediaSource.

Perhaps this could be added there?

[terry, 2014/09/05 20:22:55]

Quickly tried it and it didn't work.  I'll look at finding out why post this
checkin and try to integrate with htmlrenamer (added TODO).
