Re: [cbi-dev] Minutes: platform CBI build

[Krzysztof Daniel <kdaniel@xxxxxxxxxx>]

I think the Kepler CBI was discussed, too, but I don't remember the
output. 
Andrew,
what was the final conclusions?

Example of expected speedup - SWT CBI patches were staying in bugzilla for looong time because they were supposed to go to stable branch and I personally would not push possible breakage(considering the complexity of the build system) to stable branch but Kepler patch is something entirely different which I would have tested and pushed myself probably. I guess that many other committers feel the same way.
