# nvidia-switch utility 4.7.1
#
# A tool to install and cleanly remove the nvidia driver without stomping
# on the mesa files. Note: this tool "should" allow switching on the fly,
# but why? Pick a driver! You will stilll need to edit a bunch of other
# config files.
# When ROOT=<PATH> is specified when using {install,upgrade,remove}pkg,
# PATH is usually specified without a trailing "/", so we need to add it
