ZenTest version 4.6.0 has been released!

* <https://github.com/seattlerb/zentest>

ZenTest provides 4 different tools: zentest, unit_diff, autotest, and
multiruby.

ZenTest scans your target and unit-test code and writes your missing
code based on simple naming rules, enabling XP at a much quicker
pace. ZenTest only works with Ruby and Test::Unit. Nobody uses this
tool anymore but it is the package namesake, so it stays.

unit_diff is a command-line filter to diff expected results from
actual results and allow you to quickly see exactly what is wrong.
Do note that minitest 2.2+ provides an enhanced assert_equal obviating
the need for unit_diff

autotest is a continous testing facility meant to be used during
development. As soon as you save a file, autotest will run the
corresponding dependent tests.

multiruby runs anything you want on multiple versions of ruby. Great
for compatibility checking! Use multiruby_setup to manage your
installed versions.

Changes:

### 4.6.0 / 2011-07-22

* 6 minor enhancements:

  * Added -p (plain diff) and made -u (unified diff) the default for unit_diff.
  * Added ./tmp to default exclusions.
  * Autotest defaults unit_diff to nil now, to allow minitest's enhanced assert_equal to shine.
  * Autotest will raise if the :died handler doesn't handle the exception. (ralfebert)
  * Dropped 1.8.6 as a default tag/branch to build in multiruby.
  * autotest can now be automatically 'narrowed' on the command-line.
    * eg: `autotest lib test/test_blah.rb`

* 7 bug fixes:

  * Believe it or not... but some ppl use zentest. Fixed nested class vs module bug
  * Fix to turn on jruby's support for ObjectSpace. (stepheneb)
  * Fixed a rubygems deprecation in autotest
  * Fixed unit_diff scanning for minitest output.
  * Normalized shebangs to fix problems on windows (luis)
  * autotest/isolate.rb sets GEM_HOME as well as GEM_PATH.
  * Fixed 1.9.3 warnings.
