30 ;; This package provides functions which read a URL (Uniform Resource
31 ;; Locator) from the minibuffer, defaulting to the URL around point,
32 ;; and ask a World-Wide Web browser to load it. It can also load the
33 ;; URL associated with the current buffer. Different browsers use
34 ;; different methods of remote control so there is one function for
35 ;; each supported browser. If the chosen browser is not running, it
36 ;; is started. Currently there is support for the following browsers,
37 ;; some of them probably now obsolete:
39 ;; Function Browser Earliest version

56 ;; [A version of the Netscape browser is now free software
57 ;; <URL:http://www.mozilla.org/>, albeit not GPLed, so it is
58 ;; reasonable to have that as the default.]
60 ;; Note that versions of Netscape before 1.1b1 did not have remote
61 ;; control. <URL:http://www.netscape.com/newsref/std/x-remote.html>.
63 ;; Browsers can cache Web pages so it may be necessary to tell them to
64 ;; reload the current page if it has changed (e.g. if you have edited
65 ;; it). There is currently no perfect automatic solution to this.
67 ;; Netscape allows you to specify the id of the window you want to
68 ;; control but which window DO you want to control and how do you
71 ;; William M. Perry's excellent "w3" WWW browser for
72 ;; Emacs <URL:ftp://cs.indiana.edu/pub/elisp/w3/>
73 ;; has a function w3-follow-url-at-point, but that
74 ;; doesn't let you edit the URL like browse-url.
75 ;; The `gnuserv' package that can be used to control it in another
76 ;; Emacs process is available from
77 ;; <URL:ftp://ftp.splode.com/pub/users/friedman/packages/>.
79 ;; Grail is the freely available WWW browser implemented in Python, a
80 ;; cool object-oriented freely available interpreted language. Grail
81 ;; 0.3b1 was the first version to have remote control as distributed.
82 ;; For more information on Grail see
83 ;; <URL:http://grail.cnri.reston.va.us/> and for more information on
84 ;; Python see <url:http://www.python.org/>. Grail support in
85 ;; browse-url.el written by Barry Warsaw <bwarsaw@python.org>.
87 ;; Lynx is now distributed by the FSF. See also
88 ;; <URL:http://lynx.browser.org/>.
90 ;; Free graphical browsers that could be used by `browse-url-generic'
91 ;; include Chimera <URL:ftp://ftp.cs.unlv.edu/pub/chimera> and
92 ;; <URL:http://www.unlv.edu/chimera/>, Arena
93 ;; <URL:ftp://ftp.yggdrasil.com/pub/dist/web/arena> and Amaya
94 ;; <URL:ftp://ftp.w3.org/pub/amaya>. mMosaic
95 ;; <URL:ftp://sig.enst.fr/pub/multicast/mMosaic/>,
96 ;; <URL:http://sig.enst.fr/~dauphin/mMosaic/> (with development
97 ;; support for Java applets and multicast) can be used like Mosaic by
98 ;; setting `browse-url-mosaic-program' appropriately.
