I notice that the project has dependencies on other
libraries (boost).
Will these libraries are included in dists or will download
be required.
If the libraries will be included, is the Boost License
compatible with
the apache license?

Of course, I'm in support of this proposal. Anyone have
any concerns
to raise before we call it to a vote?

The whole Boost library is meant to be a stadards breeding
site for C++.
Much of its components, including all used by us, will
probably be a
part of the C++ standard in the future. So I do not think it
is
purposeful, though permited, to include them in
distributions.
We also use one more library - GMP, mainly for the
BigInteger like
functionality. This library is distributed under LGPL, so
downloading
and dynamic linking is the only possibility. In my opinion
legal issue
is not a problem here, as is portability. So there is a
place for
discussion.
