[svlug] Unified Makefile

[Charles Peterman]

Having recently read "Recursive Makefiles Considered Harmful", I am
attempting to apply said techniques to an existing codebase.  

Ref:
http://www.pcug.org.au/~millerp/rmch/recu-make-cons-harm.html

Can anyone refer me to an open source project that contains nested
subsystems and either 

1. A single makefile at the toplevel, and no recursive makefiles
   in the nested subsystems.
2. A master makefile at the topfile, and files which are included from
   the nested subsystems.

I am poking through the source on my system, of course, but if you know of
one off the top of your head, I would be grateful.

Thanks much,

-Charles
