# nvidia-switch utility 2.0.1
#
# A tool to install and cleanly remove the nvidia driver without stomping on the xorg files.
# Note: this tool "should" allow switching on the fly, but why? Pick a driver! You will still 
# need to edit a bunch of other config files

# TO-DO: Bounds/error checking, add more COMPAT32?
