Re: doc-view.el --- View PDF/PostStript/DVI files in Emacs

Hi Tassilo,

I made some mods to my copy of the doc-view function so that it can
either be passed a file name or called from dired:

           (dir (doc-view-file-name-to-directory-name doc)))
       (switch-to-buffer buffer)

I've also added a "V" key in my .emacs file so that dired can call
doc-view:

(defun doc-view-dired (no-cache)
  "View the current dired file with doc-view."
  (interactive "P")
  (doc-view no-cache (dired-get-file-for-visit)))

(define-key dired-mode-map "V" 'doc-view-dired)

I find this very convenient and you might want to consider adding
something similar.
