Subject: one9 - a commandline tool to convert 1.8 code to ruby 1.9.2

Hi all,
  Introducing one9, a commandline tool to make the upgrade to 1.9.2
easier. It works by spying on
your tests and detecting 1.9 changes. Once your test suite finishes,
one9 prints a report listing
the exact locations of methods that have changed in 1.9.

I'm curious to hear what is stopping us from upgrading our jobs to
1.9.2. What other tools like one9 could help with this?
Thoughts?
