So they'll see the CMake files and just go ahead and use them without realising that something experimental made it into the release.
Yeah, that clearly would happen, so the boost-cmake build won't let you proceed until you confirm that you understand the system is experimental. It looks like this: % cmake ../src -- The C compiler identification is GNU -- The CXX compiler identification is GNU -- Check for working C compiler: /usr/bin/gcc -- Check for working C compiler: /usr/bin/gcc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Check for working CXX compiler: /usr/bin/c++ -- Check for working CXX compiler: /usr/bin/c++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- ########################################################################## -- This cmake-based build system is currently under development.

Maybe it should mention specifically to keep cmake chatter off of the main boost list.
Has the CMake code merged to release been rigorously tested
Yeah, as rigorously as one could given our resources (small)
or do we at least have a means to test it prior to release - for example to test the library build process?
Sure... just build boost with it. -t
