This project builds several programs that batch factor integers and collects stats on them.
The implementation of SQUFOF is an adaptation to 64-bit and 128-bit fixed sized integers taken from the source code for Pari/GP available at http://pari.math.u-bordeaux.fr/ (Accessed April 10th, 2013).
I assume no credit for the SQUFOF code, accept no liability, and offer no warranty.
