Can you write to tech-pkg-ja@jp.netbsd.org about this?

I couldn't live w/o Japanese input, so I got ddskk dated 20011021 and made a
package attempt:

  http://mashin.nanoyo.net:81/pkgsrc/ddskk.tgz

This package assumes editors/emacs, not editors/emacs21.  I made the
dependency for ddskk emacs>=21.1.  Also I edited pkg/PLIST for
devel/apel to use 21.1 instead of 20.7.  Not very elegant.
(I'm not too sure about the dependencies of ddskk -- may be skkserv or
something is necessary...)

Hmmm, may be I shouldn't do any further work until we get one...

I guess in some sense it's simpler to not have coexistence, but then
it might make developers' lives harder...

Incredible forward compatibility too! ;-)

Perhaps someone should grep the appropriate Makefiles to determine
the maintainers to contact...
