source: libcaca/trunk/examples/frames.c @ 2821

Last change on this file since 2821 was 2821, checked in by Sam Hocevar, 11 years ago

Starting refactoring to get rid of libcucul. The initial reason for the
split is rendered moot by the plugin system: when enabled, binaries do
not link directly with libX11 or libGL. I hope this is a step towards
more consisteny and clarity.
