def content(node)
  io = website.blackboard.invoke(:source_paths)[node.node_info[:src]].io
  if node.node_info[:preprocessor]
    is_binary = website.blackboard.invoke(:content_processor_binary?, node.node_info[:preprocessor])
    context = Webgen::Context.new(:content => io.data(is_binary ? 'rb' : 'r'), :chain => [node])
    website.blackboard.invoke(:content_processor, node.node_info[:preprocessor]).call(context)
    context.content
  else
    io
  end
