;;;  Gets the a summary of the latest news from Pathfinder.com (Time
;;;  magazine and synthesizes it).  My first web based speech application.
;;;
;;;  This is far too dependent on Time's latest news pages format and
;;;  not really very general, but its a start.  Also they seem to change
;;;  both the format and the name of the pages regularly so this probably
;;;  no longer works.
;;;
;;;  Note the news in Copyright Reuters, and should not be used except
;;;  for personal use.  This program can be viewed simply as a web
;;;  browser (for one particular page) and does not itself contain any
;;;  information under Time or Reuter copyright.

;;; load the initfiles: init.scm and user's .festivalrc
