Liboil is a library of simple functions that are optimized for 
various CPUs. These functions are generally loops implementing 
simple algorithms, such as converting an array of N integers to 
floating-point numbers or multiplying and summing an array of N 
numbers. Such functions are candidates for significant optimization 
using various techniques, especially by using extended instructions 
provided by modern CPUs (Altivec, MMX, SSE, etc.).
