Can you please provide a bit more details. For example, if I want to know 
what are released versions of boost.chrono what should I do?

What is the specific command?

This is not really adequate answer IMO. What I was after is to specify my 
dependency in my Jamfile/CMakefile and make testing framework to figure out 
the rest automatically. Is this realistic/in our plans?

Even if we are talking only about local testing, I think we need to develop 
set of scripts to help boost developers with these mundane tasks.

The same here: I think we need a scripts to do this.

Why is this difficult? Do we have an information about dependency graph 
somewhere? And again I think we need a scripts to do this.

Script would be helpful.
