.SH "NAME"
.PP
cotemp - set the Color Temperature
.SH "SYNOPSIS"
.PP
\fBcotemp\fP [ \fB-dlv\fP ] [ \fB-s\fP \fIscreen\fP ] [ \fB-c\fP \fIcrtc\fP ] [ \fB-t\fP \fItemperature\fP ] [ \fB-b\fP \fIbrightness\fP ] [ \fB-p\fP \fIprofile\fP ]
.SH "DESCRIPTION"
.PP
\fBcotemp\fP is a simple program that uses Xrandr to apply a color temperature.
.br

.PP
It can also set the \fIbrightness\fP, or what someone would call it “\fIfake brightness\fP”,
since \fBcotemp\fP doesn’t access the hardware to change that, rather it changes the
values of the colors, giving them a darker tone all inside X11.
.SH "OPTIONS"
.PP
Without any arguments, cotemp will start to run every interval seconds forever.
If \fB-s\fP flag is not present, the properties will be applied to all screens.

.TP
\fB-b, --brightness brightness\fP
Sets the linear brightness and exits: [0.0 ... 1.0].
.TP
\fB-c, --crtc CRTC\fP
Zero-based index of CRTC to use.
.TP
\fB-d, --delta\fP
Shift the temperature by the \fItemp\fP (\fB-t\fP) argument value.
.TP
\fB-l, --list\fP
Print current temperature and brightness of screen(s) and exits.
.TP
\fB-s, --screen screen\fP
Zero-based index of which screen to use.
.TP
\fB-t, --temperature temp\fP
Sets the temperature and exits. Default value is \fB6500\fP and can’t be lower than \fB700\fP. If \fItemp\fP is \fB0\fP, default value is applied.
.TP
\fB-p, --profile profilename\fP
Sets the temperature and brightness of \fIprofilename\fP and exits.
.TP
\fB-v, --version\fP
Prints the version and exits.
.SH "CONFIGURATION"
.PP
cotemp is customized by creating a custom config.h and (re)compiling the source
code. This keeps it simple, since reading a config file isn’t that hard (but
adds unneeded complexity), and in many aspects more customizable. I try my best
to comment about the variables in config.h, since they don’t do anything crazy,
so it should be very straight foward what does what.
