Yep, I understood that.  The creation of the makefiles, however, must be 
completely invisible to the user.  So their first invocation of make *will* 
be the build invocation.  I cannot force them to do the generation step.

I would have to rebuild the generated makefiles every time anyway (no way 
to predict when they need to be updated).  The only performance issue I 
really need to address is reducing the multiple echo commands into a single 
command that dumps them all out at once for that dir/session.  I wish 
GNU/clearmake had a function to do it (like $(error) and $(warning)), which 
would save me the cost of using $(shell).

And since there are ordinarily a large number of directories in our users' 
source trees, I'd rather incur the cost of a simple text-output command 
than another invocation of make.  8^)
