.SH NAME
\fBlibggigcp\fR : GGI extension for color and palette
.SH DESCRIPTION
LibGGIGCP is a generic color and palette management extension. It
supports conversion between different color spaces such as RGBA,
YUV, HSV and CMYK.
.SH ENVIRONMENT VARIABLES
.TP
\fBGCP_DEBUG\fR
The debugging level for LibGGIGCP:
.RS

.TP

all debug output is on
.PP
You may also bitwise-or any of the following together:
.IP \(bu 4
2 : debug core
.IP \(bu 4
4 : debug mode setting
.IP \(bu 4
8 : debug color handling
.IP \(bu 4

32 : misc debugging output
.IP \(bu 4
64 : debug dynamic library handling
.IP \(bu 4

.PP
The debugging output can be quite verbose and in most cases you
should redirect stderr so that it does not interfere with your
program's output.
.RE

Turn on synchronous debugging output, flushing the output buffers
before returning from \fBDPRINT\fR calls.
.TP

Note that the last environment variable really begin with \fBGGI\fR,
and not \fBGCP\fR.
