Thing is, it is a library for mounting other libraries into a yet
another library's local namespace. I figured the Lib ought to be in

Yes, I think I like that a lot. Thank you.

Yep, exactly my need too. A modular Boost library not requiring Boost
needs a substitutable unit testing framework.

Easy: I didn't.
AFIO and Spinlock, like probably most Boost.Test users, only use
maybe 5% of Boost.Test's capabilities. Essentially auto test casing,
requires and checks. So that's what BindLib, soon to become Using,
For most users, Boost.Test is way overkill, it is probably why people
get so frustrated when small bugs remain unfixed in release builds
for so long. Essentially they don't care about most of Boost.Test or
the bigger picture for the library, so small unfixed problems really
For me personally, AFIO simply undef's Boost.Test internal macros and
redefs them to working fixed versions. I don't see the issues others
do with that, but then my test framework isn't tied deeply into

People don't get the concept at all yet of mapping APIs from one
location into many others. It is very new to C++ still of course.
I think the biggest technical problem preventing passing community
review is the state of the libclang based bindings generator. It
needs a whole load more work on it, but my problem is that it is
already good enough that the minor errors in its output are easily
hand repaired :(
