End Notes

• This document was created September 1996,
  probably by Sean Kelly. The material was used for
  a presentation to the Taiwan CWB, and is included
  in a spiral-bound document titled WFO-Advanced
  Seminar. The blue text on slides 5, 7, and 12 is
  from handwritten notes by Herb Grote, possibly
  added during the presentation at CWB. Slides
  19-22 are from a hand-drawn page, also by Herb
  Grote. The document was recreated December 2005
  by John Osborn from a hard copy. The most recent
  edits are by Joe Wakefield, March 2006.
