This is going to make it incredibly hard to use in the same project both
serialization and any of the libraries that changed since you set up your

I believe there are two problems in Gennadiy's proposal: the granularity is too
fine and the constraint of releasing Boost in a single whole is going to make
things unnecessarily hard.

A better approach would be to separate from core Boost some of the larger
libraries once and for all. I'm thinking of Serialization, Spirit, Python,
possibly a few others. In most cases other libraries should not depend on these
(i.e. Preprocessor is not a good candidate). Where dependencies exist they
should either be removed or moved to reside within the separate library (e.g.
serialization support for core libraries should be supplied by serialization and
not core [as I believe it is now, at least in many cases]).

These libraries should be developed, tested and released separately, against the
most recent release of core. It will be up to each library mantainers' team to
decide whether to "port" one or more released versions of their library to new
releases of Boost Core, while they work on a new major release.

This will help shorten the Core release cycle, while allowing large libraries
developers to proceed at their own pace.

Users will also benefit from not having to download/install/build libraries they
do not need.
