+.SH DESCRIPTION
+.B cg-gamma
+sets the gamma on the monitors to
+.I all
+on all channels, or
+.IR blue ,
+.IR green ,
+and
+.IR blue
+to the red, green, and blue channels, respectively. Alternatively,
+.B cg-gamma
+can change the gamma on each monitor independently by using
+reading the values from
+.I file
+or a default file.
+.P
+The file is 4 column text file where empty lines and lines
+starting with a '#', after any whitespace, are ignored.
+The values in the columns should be, in order, a monitor's
+EDID, that monitor's red gamma value, green gamma value, and
+blue gamma value.
+.SH OPTIONS
+.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
+.B \-d
+Keep the process alive and remove the filter on death.
+.TP
+.BR \-M " "\fImethod\fP

+must be a signed 64-bit integer (between -9223372036854775807
+and 9223372036854775808).
