-
-   On XFree86 systems, "man xset" reports:
-
-       -dpms    The -dpms option disables DPMS (Energy Star) features.
-       +dpms    The +dpms option enables DPMS (Energy Star) features.
-
-       dpms flags...
-                The dpms option allows the DPMS (Energy Star)
-                parameters to be set.  The option can take up to three
-                numerical values, or the `force' flag followed by a
-                DPMS state.  The `force' flags forces the server to
-                immediately switch to the DPMS state specified.  The
-                DPMS state can be one of `standby', `suspend', or
-                `off'.  When numerical values are given, they set the
-                inactivity period before the three modes are activated.
-                The first value given is for the `standby' mode, the
-                second is for the `suspend' mode, and the third is for
-                the `off' mode.  Setting these values implicitly
-                enables the DPMS features.  A value of zero disables a
-                particular mode.
-
-   However, note that the implementation is more than a little bogus,
-   in that there is code in /usr/X11R6/lib/libXdpms.a to implement all
-   the usual server-extension-querying utilities -- but there are no
-   prototypes in any header file!  Thus, the prototypes here.  (The
-   stuff in X11/extensions/dpms.h and X11/extensions/dpmsstr.h define
-   the raw X protcol, they don't define the API to libXdpms.a.)
