+;;; Commentary:
+
+;; This file implements links to open files in doc-view-mode.
+;; Org-mode loads this module by default - if this is not what you want,
+;; configure the variable `org-modules'.
+
+;; The links take the form
+;;
+;;    docview:<file path>::<page number>
+;;
+;; for example: [[docview:~/.elisp/org/doc/org.pdf::1][Org-Mode Manual]]
+;;
+;; Autocompletion for inserting links is supported; you will be
+;; prompted for a file and a page number.
+;;
+;; If you use org-store-link in a doc-view mode buffer, the stored
+;; link will point to the current page.
+
