I am a bit confused about the status of the b3 project.
At EclipseCon 2010 and Eclipse Summit Europe 2010 the new build
replacing Buckminster and eventually the (in)famous pde build,
was one of the omnipotent topics.
However I observed that the activity on the project became very
low and at EclipseCon 2011 Tycho was the only build present at all.
