I have a tutorial to describe how to use the enumerator library in
Japanese. Since it is popular among the Haskell community in Japan, I
guess it's worth translating into English. So, I did.

	http://www.mew.org/~kazu/proj/enumerator/

This tutorial explains how to use (=$) and ($=) as well as other
operators(($$), (<==<), (>>=)).

Of course, my English is broken. If English native speakers will
kindly correct broken grammar, it would be appreciated.

I'm reachable by e-mail or twitter (@kazu_yamamoto).
