I'm un-dropping off the grid to mention that the Boost mandatory source
files should be able to be directly incorporated into a user's build
system. It's been possible in the past. Maybe we should suggest to
Monotone to try that first.

I've mentioned thoughts like this before, but since our primary purpose
is creating C++ libraries, I don't want our secondary projects (like
Boost.Build) to create a NIH barrier for our users. I've finally posted
an official bug about this (#1093) at
