That would include me as well, without the use-project I get an error from 
bjam.  It still means hardcoding the path-to-boost though which is what I am 
trying to avoid.

A couple of asides:

1) I don't see this mentioned in the docs - or at least a quick grep didn't 
find it.  How about a "Refering to Boost and other bjam.v2 based projects" 
section ?
2) I'm still not convinced that defining BOOST_ALL_NO_LIB globally is a good 
idea, it just masks any bugs/incompatibilities between bbv2's name mangling 
and what auto-linking expects, but <shrug> whatever.

Thanks, John.
