[Boost-build] How to control include order?

Hi,

I have found about the && syntax (e.g. <include>a&&b ) in the
documentation. But I wonder how to maintain the include order of two
targets that have include directives in their usage requirements :

lib a : a.cpp : : <include>dir/a ;
lib b : b.cpp : : <include>dir/b ;

exe c : a&&b ;

Here I would like to specify that 'dir/a' should be included before
'dir/b'. Is there any way to that ?
