0.6.1 (2008-02-25)
========================

ruby-prof 0.6.1 add support for profiling tests cases. 

Features
--------
* Added two new methods - RubyProf.resume and RubyProf.pause. 
  RubyProf.resume takes an optional block, which ensures that
  RubyProf.pause is called.  For example:
  
  10.times do |i|
    RubyProf.resume do
      # Some long process
    end
  end
  
  result = RubyProf.stop

* Added support for profiling tests that use Ruby's built-in
  unit test framework (ie, test derived from 
  Test::Unit::TestCase).  To enable profiling simply add
  the following line of code to your test class:
  
    include RubyProf::Test
    
  By default, profiling results are written to the current 
  processes working directory.  To change this, or other
  profiling options, simply modify the PROFILE_OPTIONS hash
  table as needed.        

* Used the new support for profiling test cases to revamp
  the way that Rails profiling works.  For more information
  please refer to RubyProf's documentation.
  
  
Fixes
-------
* RubyProf.profile no longer crashes if an exception is
  thrown during a profiling run.
