With the :rdoc, :clobber_rdoc and +# :rerdoc options, you can customize the task names to your liking. +# +# For example: +# +# RDoc::Task.new(:rdoc => "rdoc", :clobber_rdoc => "rdoc:clean", +# :rerdoc => "rdoc:force") +# +# This will create the tasks :rdoc, :rdoc:clean and +# :rdoc:force. + +class RDoc::Task < Rake::TaskLib + + ## + # Name of the main, top level task.
