make is technically a tool for building applications, but it's 
amazing what a pre-processor and recursion can do for you.

This was the original GNU make version that annoyed me by using backticks and expr to do the math, hence my pure GNU Make version.. however I think there is a better way... (since I only got one vote for Bad as Hell
