##
# RDoc::Task creates the following rake tasks to generate and clean up RDoc
# output:
#
# [rdoc]
#   Main task for this RDoc task.
#
# [clobber_rdoc]
#   Delete all the rdoc files.  This target is automatically added to the main
#   clobber target.
#
# [rerdoc]
#   Rebuild the rdoc files from scratch, even if they are not out of date.
#
# Simple Example:
#
#   require 'rdoc/task'
#
#   RDoc::Task.new do |rdoc|
#     rdoc.main = "README.rdoc"
#     rdoc.rdoc_files.include("README.rdoc", "lib/**/*.rb")
#   end
#
# The +rdoc+ object passed to the block is an RDoc::Task object. See the
# attributes list for the RDoc::Task class for available customization options.
#
# == Specifying different task names
#
# 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:
#
#   require 'rdoc/task'
#
#   RDoc::Task.new :rdoc_dev do |rdoc|
#     rdoc.main = "README.doc"
#     rdoc.rdoc_files.include("README.rdoc", "lib/**/*.rb")
#     rdoc.options << "--all"
#   end
#
# The tasks would then be named :<em>rdoc_dev</em>,
# :clobber_<em>rdoc_dev</em>, and :re<em>rdoc_dev</em>.
#
# If you wish to have completely different task names, then pass a Hash as
# first argument. With the <tt>:rdoc</tt>, <tt>:clobber_rdoc</tt> and
# <tt>:rerdoc</tt> options, you can customize the task names to your liking.
#
# For example:
#
#   require 'rdoc/task'
#
#   RDoc::Task.new(:rdoc => "rdoc", :clobber_rdoc => "rdoc:clean",
#                  :rerdoc => "rdoc:force")
#
# This will create the tasks <tt>:rdoc</tt>, <tt>:rdoc:clean</tt> and
# <tt>:rdoc:force</tt>.
