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