;; detail about w3m, see:
;;
;; http://w3m.sourceforge.net/
;;; How to install:
;; See the README file in any case. We also recommend you check
;; whether a newer version of w3m is released.
;;
;; The outline of installation is: run the `configure' script and type
;; `make install' in the top directory of the emacs-w3m distribution.
