The implementation was a painful trial and error process, but I finally 
have something that's almost ready for a project to use. I have to hook 
up the bcp exe target to the action instead of using the hardcoded path. 
I had to modify bcp to add reading the module-list from a file because 
it can get very long, and doing it piecemeal means way too much 
redundant scanning! So I'll (we'll?) have to use a custom version of 
that until it gets patched in.

Here's a basically self-contained test case:
http://codepad.org/nZuE8ppq

I actually put the code in grafik's boost.jam though since that was 
simpler than adding a new module and making it depend on boost.jam. 
Perhaps this is something that would make sense in the official 
boost-build distribution? That would presumably entail using the main 
boost build Jamfiles instead of grafik's external build system.
