- /** \page libcaca-env Libcaca environment variables
-
- Some environment variables can be used to change the behaviour of
- \e libcaca without having to modify the program which uses them. These
- variables are:
-
- \li \b CACA_DRIVER: set the backend video driver. In order of preference:
- - \c conio uses the DOS conio.h interface.
- - \c ncurses uses the ncurses library.
- - \c slang uses the S-Lang library.
- - \c x11 uses the native X11 driver.
- - \c gl uses freeglut and opengl libraries.
- - \c raw outputs to the standard output instead of rendering the
- canvas. This is can be used together with cacaserver.
-
- \li \b CACA_GEOMETRY: set the video display size. The format of this
- variable must be \c XxY, with \c X and \c Y being integer values. This
- option currently works with the raw, X11 and GL drivers.
-
- \li \b 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 \c fixed or \c 5x7 is expected.
