+;; pelican-mode is an Emacs minor mode for editing pages and posts in
+;; Pelican (URL http://getpelican.com/) sites.
+;;
+;; It's intended to be used alongside `markdown-mode' or `rst-mode'.
+;; It also assumes you've set up Pelican with ``pelican-quickstart''
+;; or something like it. In particular it assumes:
+;;
+;; * The existence of ``pelicanconf.py'' and ``Makefile'' in some
+;; ancestor directory.
+;; * The first component of the path (e.g. ``content'') after that
+;; ancestor is irrelevant.
+;; * If the next component is ``pages'', that indicates a page
+;; rather than an article.
