You can do it manually, just run 'b2 headers'. Hopefully, you can
configure Visual Studio to do that before builds.

Others have responded about windows, which I know nothing about. On
linux directories are now soft links if they contain headers from only
one module, but if they contain headers from multiple modules then
they can't be a soft link.

I guess it's just slow on windows then. Btw. when referring to a wiki
page, please link to it.

Beman sent an email asking for volunteers a little while ago, but no
one responded. The build people are doing the build things, and the
test people are doing the test things, but no one is really doing the
more general things at the moment.
