I believe James Britt said he had a copy of the docs but couldn't see  
the value in putting them up:

http://groups.google.com/group/comp.lang.ruby/msg/7502f37a8a2fbf46

I filed a complaint, maybe you should add one too.  :(

I discussed enumerator in this Ruby Quiz summary:

http://www.rubyquiz.com/quiz50.html

Then daz was nice enough to point me to the docs:

http://groups.google.com/group/comp.lang.ruby/msg/46abfe771a1b0033

For what it's worth, I don't believe enumerator is what you built  
here.  The library is used to switch any given iterator to each():

 >> require "enumerator"
=> true
 >> str = "Some data..."
=> "Some data..."
 >> enum = str.enum_for(:each_byte)
=> #<Enumerable::Enumerator:0x31e348>
 >> enum.map { |byte| byte.chr }
=> ["S", "o", "m", "e", " ", "d", "a", "t", "a", ".", ".", "."]

Hope that helps.
