Boost :

I am in agreement with Lois's directory suggestion. It is that same as what
I was after, but more concise since it removes the /src under BOOST_TOP.

Why can't we reserve boost/libname for the actual code and push all the
stuff you mention into boost/libname/doc?

Not quite. If we really follow through on the suggestion some libraries
would need to be changed. For example, smart_ptr.hpp should include 4 files
from boost/smart_ptr: scoped_ptr.hpp, scoped_array.hpp, shared_ptr.hpp and
shared_array.hpp. Or if I want (and I would like to), I could include the
individual files directly from boost/smart_ptr. Right now I can't just
include scoped_ptr.hpp because scoped_ptr is lumped together with shared_ptr
into smart_ptr.hpp. I am also in favor of the *_fwd.hpp file for complex
libs as well.

I sincerely hope that Lois has time to provide some example makefiles.
While I agree with John that it is not simple due to all the variations in
make systems, it is something that needs to be done. I suspect that a good
bit of ground could be covered by providing a set of gmake compatible files
since gmake is free and widely available. Makefile generation tools (ala
John's script or Imake) would be good options as well.
