+# Define a task library for running unit tests.

+require 'rake'

+module Rake
+
+  # Create a task that runs a set of tests.
+  #
+  # Example:
+  #  
+  #   Rake::TestTask.new do |t|
+  #     t.libs << "test"
+  #     t.test_files = FileList['test/test*.rb']
+  #     t.verbose = true
+  #   end
+  #
+  # If rake is invoked with a "TEST=filename" command line option,
+  # then the list of test files will be overridden to include only the
+  # filename specified on the command line.  This provides an easy way
+  # to run just one test.
+  #
+  # If rake is invoked with a "TESTOPTS=options" command line option,
+  # then the given options are passed to the test process after a
+  # '--'.  This allows Test::Unit options to be passed to the test
+  # suite.
+  #
+  # Examples:
+  #
+  #   rake test                           # run tests normally
+  #   rake test TEST=just_one_file.rb     # run just one test file.
+  #   rake test TESTOPTS="-v"             # run in verbose mode
+  #   rake test TESTOPTS="--runner=fox"   # use the fox test runner
