Steven, this sounds really interesting!

I tried to test it out on your test program but get a lot of BBv2 errors, 
first off I had to change:

import profile_templates ;

to

import ../profile_templates ;

in the test/Jamfile.v2 otherwise I get an error from BB that it can't find 
"profile_templates".

But then I see:

c:/data/boost/boost/trunk/libs/profile_templates/test\../profile_templates.jam:32: 
in load
*** argument error
* rule path.make ( native )
* called with: (  )
* missing argument native

c:\data\boost\boost\trunk\boost-build.jam:11: in module scope

This kind of error usually happens when some variable is not defined, but I 
can't spot the problem off hand, any ideas?  Anything in user-config.jam 
that I should have set up?

Cheers, John.
