[Boost-build] Terminating bjam just before the compile starts?

Hi everyone,

I've hacked builtin.jam to provide a rudimentary capability to  
enumerate every single source file and include path that will be  
built for a given invocation of bjam (it's a primitive source code  
distribution capability).  It's not elegant but it works.  But I want  
bjam to exit once it's finished generating the source distribution.

Is there an easy way to tell when bjam has finished processing  
Jamfiles and source files and is about ready to start compiling?  I  
want to find a place in bjam's processing where my source  
distribution is complete but before it starts compiling.  The point  
here is that if a user requests a source distribution, I want to  
generate the distribution files and exit, I don't want bjam to  
continue on to the build phase.

The only solution I know if that when bjam says ...patience..., I  
know I can ctrl-C and have a complete set of source and headers  
copied to my distribution directory.  Does anyone know if the  
generator calls some function when it's about to start compiling that  
I could hook to force to bjam to exit if a distribution was  
requested?  Or maybe another way to accomplish this?

Thanks.
