$myname is a wrapper around update-alternatives supporting only configuration
of the 'glx' and 'nvidia' alternatives. After updating the alternatives, it
takes care to trigger any follow-up actions that may be required to complete
the switch.

It can be used to switch between the main NVIDIA driver version and the legacy
drivers (eg: the 304 series, the 340 series, etc).

For users with Optimus-type laptops it can be used to enable running the discrete
GPU via bumblebee.

Usage: $myname <command>

Commands:
  --auto <name>            switch the master link <name> to automatic mode.
  --display <name>         display information about the <name> group.
  --query <name>           machine parseable version of --display <name>.
  --list <name>            display all targets of the <name> group.
  --config <name>          show alternatives for the <name> group and ask the
                           user to select which one to use.
  --set <name> <path>      set <path> as alternative for <name>.

<name> is the master name for this link group.
  Only 'nvidia' and 'glx' are supported.
<path> is the location of one of the alternative target files.
  (e.g. /usr/lib/nvidia)
