  1 Overview
  ══════════

    The [introduction] to the `preview' manual reads as follows:

          Does your neck hurt from turning between previewer windows
          and the source too often? This AUCTeX component will
          render your displayed LaTeX equations right into the
          editing window where they belong.

          The purpose of preview-latex is to embed LaTeX
          environments such as display math or figures into the
          source buffers and switch conveniently between source and
          image representation.
