+
+ ##
+ # = 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.
