Usage: ${0##*/} [<options>] <DRI implementation>
       Set the dri implementation.

       --version:          Shows the version of this utility.
       --use-old:          If an implementation is already set, use that one.
       --prefix=<val>:     Set the source prefix (default: /usr)
       --dst-prefix=<val>: Set the destination prefix (default: /usr)

Usage: ${0##*/} --get-implementation

       This utility switches between DRI implementations.  There ${IS_ARE}

       ${0##*/} gallium
       This will setup things to use the gallium DRI drivers.
