# Maintainer: gilcu3
# This PKGBUILD is highly experimental and works on my Intel i7 setup
# It is not setup to produce any other targets and not yet tested on more than
# my own system.
# I have made small fixes to the AMD K8 assembly code not yet submitted upstream.
# No guarantees.
# Past Maintainer: K. Hampf <khampf@users.sourceforge.net>
