+ * This file is a small equivalent to the GNU readline library, but it
+ * was originally designed for small systems, like Atmel AVR
+ * microcontrollers (8 bits). Indeed, we don't use any malloc that is
+ * sometimes not implemented (or just not recommended) on such
+ * systems.
+ *
+ * Obviously, it does not support as many things as the GNU readline,
+ * but at least it supports some interesting features like a kill
+ * buffer and a command history.
+ *
+ * It also have a feature that does not have the GNU readline (as far
+ * as I know): we can have several instances of it running at the same
+ * time, even on a monothread program, since it works with callbacks.
+ *
+ * The lib is designed for a client-side or a server-side use:
+ * - server-side: the server receives all data from a socket, including
+ * control chars, like arrows, tabulations, ... The client is
+ * very simple, it can be a telnet or a minicom through a serial line.
+ * - client-side: the client receives its data through its stdin for
+ * instance.
