-Riece is a redesign of the Liece IRC client. The code is almost
-completely rewritten.
+Riece is mainly written by Daiki Ueno <ueno@unixuser.org>.
-Liece was mainly written by the same author of Riece. It is based on
-Irchat (version 3.01) which has been distributed under GNU General
-Public License version 1 or later. Special thanks to Tor Lillqvist,
-the original author of Irchat.
+The development of Riece has started to redesign the Liece IRC client.
+Liece was mainly written by the same author of Riece. Liece is based
+on Irchat (version 3.01) which has been distributed under GNU General
+Public License version 1 or later. Tor Lillqvist <tml@iki.fi> is the
+original author of Irchat. The current Riece source code, however,
+doesn't contain any code from Irchat. For the historical reason, the
+original copyright statement of Irchat is filed under
+doc/irchat-copyright.el.
+
+Riece has many code borrowed from other GPL'ed elisp packages such as
+Gnus, Emacs-w3m, ECB, and SEMI. I would like to thank the developers
+of these packages.
