libcaca-envLibcaca environment variables 
 \- Some environment variables can be used to change the behaviour of \fIlibcaca\fP without having to modify the program which uses it\&. These variables are:
.PP
.PD 0
.IP "\(bu" 2
\fBCACA_DRIVER:\fP set the backend video driver\&. In order of preference:
.IP "  \(bu" 4
\fCconio\fP uses the DOS conio\&.h interface\&.
.IP "  \(bu" 4
\fCncurses\fP uses the ncurses library\&.
.IP "  \(bu" 4
\fCslang\fP uses the S-Lang library\&.
.IP "  \(bu" 4
\fCx11\fP uses the native X11 driver\&.
.IP "  \(bu" 4
\fCgl\fP uses freeglut and opengl libraries\&.
.IP "  \(bu" 4
\fCraw\fP outputs to the standard output instead of rendering the canvas\&. This is can be used together with cacaserver\&.

.IP "\(bu" 2
\fBCACA_GEOMETRY:\fP set the video display size\&. The format of this variable must be \fCXxY\fP, with \fCX\fP and \fCY\fP being integer values\&. This option currently works with the raw, X11 and GL drivers\&.
.PP
.PD 0
.IP "\(bu" 2
\fBCACA_FONT:\fP set the rendered font\&. The format of this variable is implementation dependent, but since it currently only works with the X11 driver, an X11 font name such as \fCfixed\fP or \fC5x7\fP is expected\&.
