#
# == OPTIONS
# * _F_nvidia_name (defaults to NVIDIA-Linux-$_F_nvidia_arch-$pkgver-pkg$F_nvidia_pkgnum): the nvidia package name
# * _F_nvidia_arch (defaults guessed using CARCH): the nvidia package arch
# * _F_nvidia_pkgnum (defaults guessed using _F_nvidia_arch): the nvidia package number
# * _F_nvidia_linkver (defaults to pkgver): the link number used by the nvidia shared libraries
# * _F_nvidia_install (defaults to nvidia.install): Install file
# * _F_nvidia_legacyver (optionnal): version string has found at http://www.nvidia.com/object/unix.html
# * _F_nvidia_up2date (defaults depends of _F_nvidia_legacyver): an up2date grep string that will be followed
