  23 # Joshua Crawford, November 2004:
  24 #       Out of range error fixed.
  25 #       Allow for all caps "SUBJECT:".
  26 #       Display user and server name in messages.
  27 #       Don't prompt for save if no changes.
  28 #       Don't clear the screen until we're displaying a menu.
  29 #       Check for invalid choice.
  30 #       Check all arguments exist.
  31 #       Check for errors in POP.
  32 #       Return 1 on errors, 0 otherwise.
  33 # Eric S. Raymond, January 2003:
