  For those of you who aren't java-averse you can setup a debug environment
with Eclipse (or whatever your favorite JDE is) -- though, with Eclipse when
you import *build.xml* there are a few things to do to get it working.

  There are a number of exceptions that go largely ignored that, while
usually not a big deal, can help resolve obscure problems, not to mention
it's better than waiting for a bugfix if you either find an obscure problem
without a good error message, or a legitimate bug.
