Ok, will do.

I'd rather not go down that path if possible...  I often see people
using automake/autoconf as a crutch not to write portable software
from the get-go.  

However, I have often thought of moving away from Makefiles as my
primary build framework, and if I do, I'll maybe write a config script
that has similar usage.

Thanks much,
