+### Buffering
+
+Note that when you use colout within real time streams (like `tail -f X | qrep Y | colout Y`) of commands,
+you may observe that the lines are printed by large chunks and not one by one, in real time.
+This is not due to colout but to the buffering behavior of your shell.
+To fix that, use `stdbuf`, for example: `tail -f X | stdbuf -o0 grep Y | colout Y`.
