Subject [lucy-dev] [DISCUSS] Graduation (was Re: [lucy-dev] All dependency licensing issues resolved)
Date Thu, 27 Oct 2011 22:44:13 GMT
Marvin,

That's amazing!

As soon as I VOTE on the latest RC, I'm going to recommend that the Lucy 
community over the next month seriously consider graduating from the Incubator.

You've fulfilled pretty much the mantra that you set out in the Incubator:

- elected new committers
- had > 1 release manager (nice job Peter!)
- made releases
- cleaned up licensing issues

You guys are ready for prime time. What do others think? I raised this 
issue a few months ago and the major thing I remember that was raised 
was this licensing issue. 


Cheers,
Chris
