There is a ticket about this, but no conclusion about whether the vote happened or not (https://trac.einsteintoolkit.org/ticket/1410).  The minutes of the 8th August meeting do not mention it.  I think the discussion started briefly at the end of a later telecon but there was not enough time, and it hasn't been brought up again.  Specifically, I think the major objection to Boost is its size, which can be ameliorated by changing the way the repository is structured, or the way that external thorns work (e.g. downloading the library tarball when needed, rather than on checkout).  The toolkit is only supposed to contain components which have been agreed on.  Since Boost is not yet (as far as I know) part of the toolkit, I don't think it should be downloaded with the toolkit by default.  It should be commented out in the thornlist, so that use
rs can add it back in if they want, until we agree on whether it should be included, and in what form.

have you looked into the possibility of using git-annex
for large binary files? It is a tool that acts on top
of a git repository and it commits only symbolic links
to the data you choose into the git repository. A checkout
then would be quick and you could choose to bring in
from a central repository only the data you want
if or when you need it. Please take a look into the
following link for more info:


specially the walk through link:


It may be helpful when dealing with external libraries
tar balls.
