@return [RSS:Rss]

# File lib/html2rss.rb, line 23
def self.feed_from_yaml_config(file, name)
  # rubocop:disable Security/YAMLLoad
  yaml = YAML.load(File.open(file))
  # rubocop:enable Security/YAMLLoad

  feed_config = yaml['feeds'][name]
  global_config = yaml.reject { |key| key == 'feeds' }

  config = Config.new(feed_config, global_config)
  feed(config)
