module RSS

##
  # = RSS 1.0 support
  #
  # RSS has three different versions. This module contains support for version
  # 1.0[http://web.resource.org/rss/1.0/]
  #
  # == Producing RSS 1.0
  #
  # Producing our own RSS feeds is easy as well. Let's make a very basic feed:
  #
  #  require "rss"
  #
  #  rss = RSS::Maker.make("1.0") do |maker|
  #    maker.channel.language = "en"
  #    maker.channel.author = "matz"
  #    maker.channel.about = "About my feed."
  #    maker.channel.updated = Time.now.to_s
  #    maker.channel.link = "http://www.ruby-lang.org/en/feeds/news.rss"
  #    maker.channel.title = "Example Feed"
  #    maker.channel.description = "A longer description of my feed."
  #    maker.items.new_item do |item|
  #      item.link = "http://www.ruby-lang.org/en/news/2010/12/25/ruby-1-9-2-p136-is-released/"
  #      item.title = "Ruby 1.9.2-p136 is released"
  #      item.updated = Time.now.to_s
  #    end
  #  end
  #
  #  puts rss
  #
  # As you can see, this is a very Builder-like DSL. This code will spit out an
  # RSS 1.0 feed with one item. If we needed a second item, we'd make another
  # block with maker.items.new_item and build a second one.
