[Jaroslav Reznik]

As decided by FESCo on 2012-12-05 meeting, all proposed Features are required
to pass through the community review by announcing them on devel-announce list.
FESCo votes on new features no sooner than a week from the announcement.

* Detailed description:
That feature aims at synchronising the top of the Fedora tree with the 
current Boost upstream release. The current Fedora release is boost-1.50.0.

As of Fedora 13, the canonical sources used for the package switched from 
the official Boost release (with BJam build) to an alternate repository 
(with CMake build, for boost-1.41.0). That alternate repository has been 
deprecated and may be deleted any time soon (as of January 2013). 
boost-1.41.0 has been delivered from that (now deprecated) Boost-CMake 
repository (hosted on Gitorious), where the code base had slightly diverged
from upstream.
