;;; Commentary:
;; Emacs-w3m is an Emacs interface to the w3m program. For more
;; 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.
;;; Code:
;; Developers, you must not use the cl functions (e.g., `butlast',
;; `coerce', `merge', etc.) in any emacs-w3m or shimbun modules. To
;; exclude run-time cl is the policy of emacs-w3m. However, XEmacs
;; employs the cl package for all time, or those functions are
;; possibly provided in the other modules like APEL, so you may use
;; them only in w3m-xmas.el or w3m-om.el.

may strip it off with the following directives:

For fvwm version 1 use this in your .fvwmrc:

"*Alist of regexps matching URIs, and some types of replacements.
It can be used universally to replace URI strings in the local rule to
the valid forms in the Internet.
Each element looks like the `(REGEXP FUNCTION OPTIONS...)' form.
FUNCTION takes one or more arguments, a uri and OPTIONS. You can use
the grouping constructs \"\\\\(...\\\\)\" in REGEXP, and they can be
referred by the \"\\N\" forms in a replacement (which is one of OPTIONS).
Here are some predefined functions which can be used for those ways:
`w3m-pattern-uri-replace'
Replace a URI using PATTERN (which is just an OPTION). It is
allowed that PATTERN contains the \"\\N\" forms in the same manner
of `replace-match'.
`w3m-search-uri-replace'
Generate the valid forms to query words to some specified search
engines. For example, the element
(\"\\\\`gg:\" w3m-search-uri-replace \"google\")
makes it possible to replace the URI \"gg:emacs\" to the form to
query the word \"emacs\" to the Google site.\

When you invoke this command interactively for the first time, it will
visit a page which is pointed to by a string like url around the
cursor position or the home page specified by the `w3m-home-page'
variable, but you will be prompted for a URL if `w3m-quick-start' is
nil (default t) or `w3m-home-page' is nil.
The variables `w3m-pop-up-windows' and `w3m-pop-up-frames' control
whether this command should pop to a window or a frame up for the
session.
When emacs-w3m sessions have already been opened, this command will
pop to the existing window or frame up, but if `w3m-quick-start' is
nil, \(default t), you will be prompted for a URL (which defaults to
`popup' meaning to pop to an existing emacs-w3m buffer up).
In addition, if the prefix argument is given or you enter the empty
string for the prompt, it will visit the home page specified by the
`w3m-home-page' variable or the \"about:\" page.
You can also run this command in the batch mode as follows:
emacs -f w3m http://emacs-w3m.namazu.org/ &
In that case, or if this command is called non-interactively, the
variables `w3m-pop-up-windows' and `w3m-pop-up-frames' will be ignored
\(treated as nil) and it will run emacs-w3m at the current (or the
initial) window.
If the optional NEW-SESSION is non-nil, this function makes a new
emacs-w3m buffer. Besides that, it also makes a new emacs-w3m buffer
if `w3m-make-new-session' is non-nil and a user specifies a url string.
