##
# = RSS 2.0 support
#
# RSS has three different versions. This module contains support for version
# 2.0[http://www.rssboard.org/rss-specification]
#
# == Producing RSS 2.0
#
# Producing our own RSS feeds is easy as well. Let's make a very basic feed:
#
# require "rss"
#
# rss = RSS::Maker.make("2.0") do |maker|
# maker.channel.language = "en"
# maker.channel.author = "matz"
# 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 2.0 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.
