The setting above is what I'd expect. The question is how to order the 
libraries. If 'DirectSubLibs' is "a" and "b", I assumed something like:

lib a : a.cpp : <library>b ;
lib b : b.cpp ;

would result in 'b' put before 'a' on the linker's command line. Now, I'm 
having problems defending this approach --- yours looks better. So, please 
you <dependency> feature. In future, then <dependency> will be renamed to
<using> we'll have

lib a : a.cpp : <using>b ;
lib b : b.cpp ;

which is quite intuitive.
