Notes
=====

    - A line in the body of a post is considered to be original if it
      does *not* match the regular expression /^\s{0,3}(?:>|:|\S+>|\+\+|\|\s+|\*\s)/.
    - All text after the last cut line (/^-- $/) in the body is
      considered to be the author's signature.
    - The scanner prefers the Reply-To: header over the From: header
      in determining the "real" e-mail address and name.
    - Original Content Rating is the ratio of the original content volume
      to the total body volume.
    - Please send all comments to Christopher Browne <cbbrowne@acm.org>
