Minimal Boost.Jam

 As an exercise, I created, what I thought was a minimal
Boost.Jam file.

rule foo
{
ECHO "Hello, World!" ;
}

foo ;

When I execute it, I get:

Hello, World!
don't know how to make all
...found 1 target...
...can't find 1 target...

Two simple questions about the minimal script.

1) Is foo a target? Or is rule a target?

2) What is the minimal Boost.Jam that will know how to make all?
