[boost] Experimenting with modular Boost

The instructions at https://svn.boost.org/trac/boost/wiki/TryModBoost
seem to be bogus, apparently because the cloned repo contains no
.gitmodules file so the 'git submodule update --init' command does
nothing, and I then get an error for the last step:

$ cmake -P forward_headers.cmake
CMake Error: Error processing file:forward_headers.cmake

I'm "only" using Git 1.7.12 but I don't think that's the problem.

The older instructions at
https://svn.boost.org/trac/boost/wiki/CMakeModularizationStatus refer
to a non-existent http://github.com/boost-lib/boost URL, so they don't
work either.

I've looked at several other wiki pages, but they're also inconsistent
or don't help. Is there any accurate documentation for modular Boost?

How does someone try modular boost?
