+.SH DESCRIPTION
+.B cg-sleepmode
+gradually fade out the red, green, and blue channels on the
+monitors to the brilliances of
+.IR red-luminosity ,
+.IR green-luminosity ,
+and
+.IR blue-luminosity ,
+respectively, whose default values are 0.25, 0, and 0,
+respectively. A value of 0 means complete darkness, a
+value of 1 means normal brilliance.
+.P
+.B cg-sleepmode
+does not exist after the channels have been faded out,
+instead, it's waits until it's killed, and then fades the
+channel's back in to normal brilliance.
+.SH OPTIONS
+.TP
+.BR \-r " "\fIred-fadeout-time\fP
+Set the fade-out time for the red channel to
+\fIred-fadeout-time\fP seconds. The fade-in time is based
+on this value. The default fadeout time for the red channel
+is 3 seconds.
+.TP
+.BR \-g " "\fIgreen-fadeout-time\fP
+Set the fade-out time for the green channel to
+\fIgreen-fadeout-time\fP seconds. The fade-in time is based
+on this value. The default fadeout time for the green channel
+is 2 seconds.
+.TP
+.BR \-b " "\fIblue-fadeout-time\fP
+Set the fade-out time for the blue channel to
+\fIblue-fadeout-time\fP seconds. The fade-in time is based
+on this value. The default fadeout time for the blue channel
+is 1 second.
+.TP
+.BR \-c " "\fIcrtc\fP
+Apply the filter to the CRTC with the monitor whose EDID is
+.IR crtc .
+By default, the filter is applied to all monitors.
+.TP
+.BR \-M " "\fImethod\fP
+Adjustment method name or number. Recognised names include:
+
+.nf
+\fBdummy\fP      Dummy method
+\fBrandr\fP      X RAndR

+.BR libgamma (7).
+Only methods that were enabled when
+.B libgamma
+was compiled will be supported.
+.TP
+.BR \-p " "\fIpriority\fP
+Set the priority of the filter. Filters with lower priority
+are applied before filters with higher priority. The value
+must be a signed 64-bit integer (between -9223372036854775807
+and 9223372036854775808).
+.BR cg-sleepmode 's
+default priority is 1729382256910270464.
+.TP
+.BR \-R " "\fIrule\fP
+Set the rule of of the filter to
