  # == Introduction
  # 
  # Unit testing is making waves all over the place, largely due to the
  # fact that it is a core practice of XP. While XP is great, unit testing
  # has been around for a long time and has always been a good idea. One
  # of the keys to good unit testing, though, is not just writing tests,
  # but having tests. What's the difference? Well, if you just _write_ a
  # test and throw it away, you have no guarantee that something won't
  # change later which breaks your code. If, on the other hand, you _have_
  # tests (obviously you have to write them first), and run them as often
  # as possible, you slowly build up a wall of things that cannot break
  # without you immediately knowing about it. This is when unit testing
  # hits its peak usefulness.
  # 
  # Enter Test::Unit, a framework for unit testing in Ruby, helping you to
  # design, debug and evaluate your code by making it easy to write and
  # have tests for it.
  # 
  # 
  # == Notes
  # 
  # Test::Unit has grown out of and superceded Lapidary.

  # == Feedback
  # 
  # I like (and do my best to practice) XP, so I value early releases,
  # user feedback, and clean, simple, expressive code. There is always
  # room for improvement in everything I do, and Test::Unit is no
  # exception. Please, let me know what you think of Test::Unit as it
  # stands, and what you'd like to see expanded/changed/improved/etc. If
  # you find a bug, let me know ASAP; one good way to let me know what the
  # bug is is to submit a new test that catches it :-) Also, I'd love to
  # hear about any successes you have with Test::Unit, and any
  # documentation you might add will be greatly appreciated. My contact
  # info is below.
