# Emacs 23 daemon capability is a killing feature.
  # One emacs process handles all your frames whether
  # you use a frame opened in a terminal via a ssh connection or X frames
  # opened on the same host.
  
  # Benefits are multiple
  # - You don't have the cost of starting Emacs all the time anymore
  # - Opening a file is as fast as Emacs does not have anything else to do.
  # - You can share opened buffered across opened frames.
  # - Configuration changes made at runtime are applied to all frames.
