No builtin facility yet. Maybe, you could file a feature request in our issue 
tracker?

Assuming you'd like this to work right now, you can fake this feature 
yourself. The $boost_root/test/unused/project-root.jam creates a new main 
target rule, which produces no target and only returns usage requirements.

By changing names, making body of 'construct' empty and removing 
'compute-usage-requirements' method, you'll be able to get 
'header-only-library' rule, which does what you'll want. 

Of course, you might prefer to wait while proper interface is decided on and 
implemented. It's up to you.
