;;; Commentary:
-;; The latest version of this package should be available from
-;; <URL:http://wombat.doc.ic.ac.uk/emacs/browse-url.el>.
-
;; This package provides functions which read a URL (Uniform Resource
;; Locator) from the minibuffer, defaulting to the URL around point,
;; and ask a World-Wide Web browser to load it. It can also load the
;; is started. Currently there is support for:
;; Function Browser Earliest version
-;; browse-url-netscape Netscape 1.1b1
-;; browse-url-mosaic XMosaic <= 2.4
+;; browse-url-netscape Netscape 1.1b1

;; browse-url-lynx-* Lynx 0
;; browse-url-grail Grail 0.3b1

;; Netscape can cache Web pages so it may be necessary to tell it to

;; Emacs <URL:ftp://cs.indiana.edu/pub/elisp/w3/>
;; has a function w3-follow-url-at-point, but that

-;; This package generalises function html-previewer-process in Marc
-;; Andreessen <marca@ncsa.uiuc.edu>'s html-mode (LCD
-;; modes/html-mode.el.Z) and provides better versions of the URL
-;; functions in Michelangelo Grigni <mic@cs.ucsd.edu>'s ffap.el
-;; (find-file-at-point) <URL:ftp://cs.ucsd.edu:/pub/mic/>. The huge
-;; hyperbole package also contains similar functions.
+;; The `gnuserv' package that can be used to control it in another
+;; Emacs process is available from
+;; <URL:ftp://ftp.splode.com/pub/users/friedman/packages/>.
;; Grail is the freely available WWW browser implemented in Python, a
;; cool object-oriented freely available interpreted language. Grail
;; 0.3b1 was the first version to have remote control as distributed.
;; For more information on Grail see
-;; <URL:http://monty.cnri.reston.va.us/> and for more information on
+;; <URL:http://grail.cnri.reston.va.us/> and for more information on
;; Python see <url:http://www.python.org/>. Grail support in
;; browse-url.el written by Barry Warsaw <bwarsaw@python.org>.
+;; MMM is the freely available WWW browser implemented in Objective
+;; Caml, a cool impure functional programming language, by Francois
+;; Rouaix. See the MMM home page
+;; <URL:http://pauillac.inria.fr/%7Erouaix/mmm/>.
+
+;; Lynx is now distributed by the FSF. See also
+;; <URL:http://lynx.browser.org/>.
+
+;; Free graphical browsers that could be used by `browse-url-generic'
+;; include Chimera <URL:ftp://ftp.cs.unlv.edu/pub/chimera> and
+;; <URL:http://www.unlv.edu/chimera/>, Arena
+;; <URL:ftp://ftp.yggdrasil.com/pub/dist/web/arena> and Amaya
+;; <URL:ftp://ftp.w3.org/pub/amaya>. mMosaic
+;; <URL:ftp://sig.enst.fr/pub/multicast/mMosaic/> (with development
+;; support for Java applets and multicast) can be used like Mosaic by
+;; setting `browse-url-mosaic-program' appropriately.
+
+;; I [Denis Howe] recommend Nelson Minar <nelson@santafe.edu>'s excellent
+;; html-helper-mode.el for editing HTML and thank Nelson for

+;; PSGML the general SGML structure editor package
+;; <URL:ftp://ftp.lysator.liu.se/pub/sgml>; hm--html-menus can be used

+
+;; This package generalises function html-previewer-process in Marc

;; Help!
;; Do any other browsers have remote control?
-;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
-;; Installation
-
-;; Put the following in your ~/.emacs file:
-;;
-;; (autoload 'browse-url-at-point "browse-url"
-;; "Ask a WWW browser to load the URL at or before point." t)
-;; (autoload 'browse-url-at-mouse "browse-url"
-;; "Ask a WWW browser to load a URL clicked with the mouse." t)
-;; (autoload 'browse-url-of-buffer "browse-url"
-;; "Ask a WWW browser to display BUFFER." t)
-;; (autoload 'browse-url-of-file "browse-url"
-;; "Ask a WWW browser to display FILE." t)
-;; (autoload 'browse-url-of-dired-file "browse-url"
-;; "In Dired, ask a WWW browser to display the file named on this line." t)
-
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;; Usage
;; To display the URL at or before point:
;; M-x browse-url-at-point RET
+;; or, similarly but with the opportunity to edit the URL extracted from
+;; the buffer, use:
+;; M-x browse-url
;; To display a URL by shift-clicking on it, put this in your ~/.emacs
;; file:
;; To display the current buffer in a web browser:
;; M-x browse-url-of-buffer RET
+;; To display the current region in a web browser:
+;; M-x browse-url-of-region RET
+
;; In Dired, to display the file named on the current line:
;; M-x browse-url-of-dired-file RET
;; Customisation (~/.emacs)
;; To see what variables are available for customization, type
-;; `M-x set-variable browse-url TAB'.
+;; `M-x set-variable browse-url TAB'. Better, use
+;; `M-x customize-group browse-url'.
;; Bind the browse-url commands to keys with the `C-c C-z' prefix
;; (as used by html-helper-mode):
;; (global-set-key "\C-c\C-z." 'browse-url-at-point)
;; (global-set-key "\C-c\C-zb" 'browse-url-of-buffer)
+;; (global-set-key "\C-c\C-zr" 'browse-url-of-region)
;; (global-set-key "\C-c\C-zu" 'browse-url)

-;; (add-hook 'dired-mode-hook

+;; (add-hook 'rmail-mode-hook (lambda () ; rmail-mode startup

;; '(define-key gnus-article-mode-map [mouse-2] 'browse-url-at-mouse))
+;; [The current version of Gnus provides a standard feature to
+;; activate URLs in article buffers for invocation of browse-url with

;; Use the Emacs w3 browser when not running under X11:
;; (or (eq window-system 'x)
-;; (setq browse-url-browser-function 'browse-url-w3))
+;; (setq browse-url-browser-function 'browse-url-w3))
;; To always save modified buffers before displaying the file in a browser:
-;; (setq browse-url-save-file t)
+;; (setq browse-url-save-file t)
;; To get round the Netscape caching problem, you could EITHER have
;; write-file in html-helper-mode make Netscape reload the document:
;;
-;; (autoload 'browse-url-netscape-reload "browse-url"
-;; "Ask a WWW browser to redisplay the current file." t)
-;; (add-hook 'html-helper-mode-hook
-;; (function (lambda ()
-;; (add-hook 'local-write-file-hooks
-;; (function (lambda ()
-;; (let ((local-write-file-hooks))
-;; (save-buffer))
-;; (browse-url-netscape-reload)
-;; t)) ; => file written by hook
-;; t)))) ; append to l-w-f-hooks
+;; (autoload 'browse-url-netscape-reload "browse-url"
+;; "Ask a WWW browser to redisplay the current file." t)

+;; (lambda ()

+;; (lambda ()
+;; (let ((local-write-file-hooks))
+;; (save-buffer))
+;; (browse-url-netscape-reload)
+;; t) ; => file written by hook
+;; t))) ; append to l-w-f-hooks
;;
;; OR have browse-url-of-file ask Netscape to load and then reload the
;; file:
;;
-;; (add-hook 'browse-url-of-file-hook 'browse-url-netscape-reload)
+;; (add-hook 'browse-url-of-file-hook 'browse-url-netscape-reload)
;; You may also want to customise browse-url-netscape-arguments, e.g.
-;; (setq browse-url-netscape-arguments '("-install"))
+;; (setq browse-url-netscape-arguments '("-install"))
;;
-;; or similarly for the other browsers.
