##
# RDoc::RI::Task creates ri data in <code>./.rdoc</code> for your project.
#
# It contains the following tasks:
#
# [ri]
#   Build ri data
#
# [clobber_ri]
#   Delete ri data files.  This target is automatically added to the main
#   clobber target.
#
# [reri]
#   Rebuild the ri data from scratch even if they are not out of date.
#
# Simple example:
#
#   require 'rdoc/ri/task'
#
#   RDoc::RI::Task.new do |ri|
#     ri.main = 'README.rdoc'
#     ri.rdoc_files.include 'README.rdoc', 'lib/**/*.rb'
#   end
#
# For further configuration details see RDoc::Task.
