;;; Commentary:
;; Kanji-and-Kana mixed text or Katakana text by commands specified in
;; CONVERSION-KEYS argument of the Quail package.
+;; [There was an input method for Mule 2.3 called `Tamago' from the
+;; Japanese `TAkusan MAtasete GOmenasai', or `Sorry for having you
+;; wait so long'; this couldn't be included in Emacs 20. `Tamago' is
+;; Japanese for `egg' (implicitly a hen's egg). Handa-san made a
+;; smaller and simpler system; the smaller quail egg is also eaten in
+;; Japan. Maybe others will be egged on to write more sorts of input
+;; methods.]
