I'll throw in my $0.02 too... If the current build system were replaced, 

I'd like to not lose one specific feature: fully parallel builds.  At 

present, given the "single Makefile in src/", I can actually use all 4 

CPUs to do compiles, etc.  I don't want to regress to having a separate 

Makefile in every subdirectory.  :)

Great, thanks informing me so I can check this out. If you remember I'm

pretty unfamiliar with build systems. I have no idea what you are

talking about. Can I get a link or a more detailed explaination?
