       libcaca-env - Libcaca environment variables

       Some environment variables can be used to change the behaviour of libcaca without having to modify the
       program which uses it. These variables are:

       •
        CACA_DRIVER: set the backend video driver. In order of preference:
         • conio uses the DOS conio.h interface.
         • ncurses uses the ncurses library.
         • slang uses the S-Lang library.
         • x11 uses the native X11 driver.
         • gl uses freeglut and opengl libraries.
         • raw outputs to the standard output instead of rendering the canvas. This is can be used together with
           cacaserver.
       •
        CACA_GEOMETRY:  set  the video display size. The format of this variable must be XxY, with X and Y being
        integer values. This option currently works with the raw, X11 and GL drivers.
       •
        CACA_FONT: 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 fixed or 5x7 is expected.
