Usage: ${0##*/} [<options>] <GL implementation>
       Set the opengl implementation.
       Valid options:
       --help|-h|-?:       Prints this help.
       --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)
       --impl-headers:     Use headers provided by this implementation to
                           override global ones provided by opengl-update.

Usage: ${0##*/} --get-implementation
       Print the current implementaion

Notes:
       --impl-headers was default in <opengl-update-2.2.

       This utility switches between OpenGL implementations.  There ${IS_ARE}
       $(echo ${AVAIL_IMPLEMS} | wc -w) available implementation${IMPLEM_PLURAL}: ${AVAIL_IMPLEMS}

Examples:
       ${0##*/} xorg
       This will setup things to use libGL.so from X.org.

       ${0##*/} nvidia
       This will setup things to use libGL.so from the nVidia drivers.
