    <title>Introduction to Ed</title>

    <para>
      <application>Ed</application> is a line-oriented text editor. It
      is used to create, display, modify and otherwise manipulate text files,
      both interactively and via shell scripts. Ed isn't something which many
      people use. It's described here because it can be used by the patch
      program if you encounter an ed-based patch file. This happens rarely
      because diff-based patches are preferred these days.
