Hi, Noel,

I haven't tried exactly that, but I think you can do something like what
we've done. I put a "project" statement in my Jamroot.jam file that
sets requirements and default build settings. This might do what you want:

project rootproject
    : requirements

You could also do things based on the OS you were running on (using "[
modules.peek : OS ]") or which toolsets are set up (using "[
feature.values <toolset> ]"). Then, you could set a variable to go in
the requirements section of the project statement so you wouldn't have
to have all of the toolset requirements on the project statement. You
could leave off the "<toolset>foo," part, too, if there's only one
toolset set up. :-) But I digress.
