+the Jabber IM network is built).
+Its goal is to let you connect very easily (no account creation needed) to the
+network and join various chatrooms, immediately.  It tries to look like the
+most famous IRC clients (weechat, irssi, etc).  Many commands are identical and
+you won't be lost if you already know these clients.  Configuration can be
+made in a configuration file or directly from the client.
+You'll find the light, fast, geeky and anonymous spirit of IRC while using a
+powerful, standard and open protocol.")
