+  # Create a documentation task that will generate the RDoc files for
+  # a project.
+  #
+  # The RDocTask will create the following targets:
+  #
+  # [<b><em>rdoc</em></b>]
+  #   Main task for this RDOC task.  
+  #
+  # [<b>:clobber_<em>rdoc</em></b>]
+  #   Delete all the rdoc files.  This target is automatically
+  #   added to the main clobber target.
+  #
+  # [<b>:re<em>rdoc</em></b>]
+  #   Rebuild the rdoc files from scratch, even if they are not out
+  #   of date.
+  #
+  # Simple Example:
+  #
+  #   Rake::RDocTask.new do |rd|
+  #     rd.main = "README.rdoc"
+  #     rd.rdoc_files.include("README.rdoc", "lib/**/*.rb")
+  #   end
+  #
+  # You may wish to give the task a different name, such as if you are
+  # generating two sets of documentation.  For instance, if you want to have a
+  # development set of documentation including private methods:
+  #
+  #   Rake::RDocTask.new(:rdoc_dev) do |rd|
+  #     rd.main = "README.doc"
+  #     rd.rdoc_files.include("README.rdoc", "lib/**/*.rb")
+  #     rd.options << "--all"
+  #   end
+  #
+  # The tasks would then be named :<em>rdoc_dev</em>, :clobber_<em>rdoc_dev</em>, and
+  # :re<em>rdoc_dev</em>.
