So that's something that should probably be documented better.  The code
that I wrote relies on pre-existing history enabler code.  It is meant
as a supplement to something like Michael Granger's persistent IRB
history:

http://www.rubygarden.org/Ruby/page/show/Irb/TipsAndTricks

or Wirble (gem install wirble), which just packages the above with some
other IRB hacks. If you set up Michael's code or install wirble and
enable history, it'll save your history between sessions.

My code does not replace that stuff; it serves a different purpose.
Mine is about accessing the history you already have.  I've been meaning
to re-open a conversation I was having with wirble's author over a year
ago, to get my code included there.  Once that happens (if Paul is still
interested), you'll be able to just install/enable wirble and have all
your history goodies for free.

Hope that answers your question :)
