Note the following important things:
Using the compatibility layer is as easy as adding the following three lines:
#include <caca.h>
libcaca program - 0.x API
...
| #include <caca.h> #ifdef CACA_API_VERSION_1 # include <caca0.h> #endif libcaca program - 0.x API ... |

caca-config
utility is deprecated in favour of the standard pkg-config
interface:
gcc -c foobar.c -o foobar.o `pkg-config --cflags caca` gcc foobar.o -o foobar `pkg-config --libs caca`
caca-config
is still provided as a convenience tool but may be removed in the future.
