Sorry for not getting to this sooner. I have been travelling for the
last week and a half. I just got home on Sunday and I am suffering
from a pretty bad bout of jet lag as I am overcoming a 12.5 hour time
change. The earliest I can probably get to this for review would be
tomorrow morning (8/14 in the AM PDT) as my calendar has me fully
booked with meetings most of today.

Thanks,
