This branch is the equivalent of the old SVN trunk. It enables testing of
the develop branches of the submodules. The typical Boost developer workflow

- make changes
- run local tests
- when those pass, commit to develop (SVN trunk)
- wait a few days for the develop (SVN trunk) testers to cycle
- when those pass, merge to master (SVN release)

In addition, testing a composition of the develop branches of the submodules
enables people to detect inadvertent breaking changes in a dependent
submodule and complain loudly. This ideally happens before the merge to
master. (Or, alternatively, if the changes were in fact deliberate, it
enables them to fix their code ahead of the merge to master.)

That's not - quite - true. The develop branches are expected to work, even
though this is not strictly enforced. We mostly rely on the honor system.
