+# Define a task library for running RSpec contexts.
+
+require 'rake'
+require 'rake/tasklib'
+
+module Spec
+  module Rake
+
+    # A Rake task that runs a set of specs.
+    #
+    # Example:
+    #
+    #   Spec::Rake::SpecTask.new do |t|
+    #     t.warning = true
+    #     t.rcov = true
+    #   end
+    #
+    # This will create a task that can be run with:
+    #
+    #   rake spec
+    #
+    # If rake is invoked with a "SPEC=filename" command line option,
+    # then the list of spec files will be overridden to include only the
+    # filename specified on the command line.  This provides an easy way
+    # to run just one spec.
+    #
+    # If rake is invoked with a "SPEC_OPTS=options" command line option,
+    # then the given options will override the value of the +spec_opts+
+    # attribute.
+    #
+    # If rake is invoked with a "RCOV_OPTS=options" command line option,
+    # then the given options will override the value of the +rcov_opts+
+    # attribute.
+    #
+    # Examples:
+    #
+    #   rake spec                                      # run specs normally
+    #   rake spec SPEC=just_one_file.rb                # run just one spec file.
+    #   rake spec SPEC_OPTS="--diff"                   # enable diffing
+    #   rake spec RCOV_OPTS="--aggregate myfile.txt"   # see rcov --help for details
+    #
+    # Each attribute of this task may be a proc. This allows for lazy evaluation,
+    # which is sometimes handy if you want to defer the evaluation of an attribute value
+    # until the task is run (as opposed to when it is defined).
+    #
+    # This task can also be used to run existing Test::Unit tests and get RSpec
+    # output, for example like this:
+    #
+    #   require 'spec/rake/spectask'
+    #   Spec::Rake::SpecTask.new do |t|
+    #     t.ruby_opts = ['-rtest/unit']
+    #     t.spec_files = FileList['test/**/*_test.rb']
+    #   end
+    #
+    class SpecTask < ::Rake::TaskLib
+      def self.attr_accessor(*names)
+        super(*names)
+        names.each do |name|
