----------------------------------------------------------
Apologies for the spurious posts. I had a few issues with my review tools
setup. I have posted a RB review: https://reviews.apache.org/r/19573/
I'll post an updated patch with some changes and clean-up soon.
By the way, I noticed that the {{request-patch-review.py}} tool uses the old
{{post-review}} tool, which will be deprecated in favor of {{rbt}} soon. If you
would like, I can open a ticket and help clean it up, add a {{.reviewboardrc}}
to the source tree, and use {{rbt}} to post the review.
