Project IDs

I was just reading through boost_build_v2.html, and even though I was
in on the design of these features, I've forgotten a lot, so I here
are my remarks:

1. target/Project IDs are mentioned without any introduction. Some
introductory description needs to be written. I'd do it, but I'm
not clear on the concepts anymore ;-S

2. The example shows:

use-project /lib1 : lib/lib1 ;
exe app : app.cpp @/lib1/lib1 ;

What's the meaning of the initial slash? What would it mean if I wrote:

use-project lib1 : lib/lib1 ;
exe app : app.cpp @lib/lib1 ;

??

3. What's the scope of these target IDs? Suppose two different
projects do "use-project /lib1"?
