Of course, users may have installed JapaneseCodecs with
--without-aliases, in which case the aliases won't be there
(neither automatically, nor after explicitly importing japanese).
I believe mailman use it that way
So people who currently do

encodings.aliases.aliases.update(
   {"shift_jis" : "japanese.shift_jis"})

would have to adjust their code.

I also find that installing JapaneseCodecs on top of a CJK-enabled
Python 2.4 causes shift_jis to use the CJK codec, not the japanese
codec.
