  26 ;; This defines a new url type, which is like the interwiki support of
  27 ;; muse-wiki. You can also publish to a different directory structure
  28 ;; from the file space (which I do for historical reasons). So a link
  29 ;; like
  30
  31 ;; [[iw:home\emacs][hello]] will work from any of the individual muse
  32 ;; projects that I have.
