[Boost-build] Seperating objects and libraries

I'm looking at replacing our current build-system with something new (for 
various reasons). This is a several million line system so i've been looking 
at boost.build.v2 amongst others.

One feaure I would like is to keep the build output separate from the source 
using build-dir - however I would like to put the objects and intermediate 
files in a separate location to the libries and binaries.  

I'd also like to drop the default ".../msvc-7.1/debug" extensions that get 
added onto build-dir as well.

Ideally all the objects would end up under a "obj" folder, with one separate 
sub-folder per library/project then there would be a lib folder and bin 
folders.

Something like this was dicussed before (see 
http://thread.gmane.org/gmane.comp.lib.boost.build/9519/focus=9535)

And there the suggestion was to use stage for this, but then elsewhere I read 
that stage involves a relink. I would like to be able to specify the ouput 
where the actual link goes to in the first place.  

Ideally the output would end up something like

Workspace
|
+-src          // All the source code/Jamfiles etc below here
|
+-win32        // Windows 32 output
| |
| +-obj        // intermediate files
| | |
| | +-library1 // objects for library (or project) 1
| |
| +-lib        // library files
| |
| +-bin        // Executables
|
+-sol          // Solaris output (then the same structure as above)
