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

55 ;; [A version of the Netscape browser is now free software
56 ;; <URL:http://www.mozilla.org/>, albeit not GPLed, so it is
57 ;; reasonable to have that as the default.]
59 ;; Note that versions of Netscape before 1.1b1 did not have remote
60 ;; control. <URL:http://www.netscape.com/newsref/std/x-remote.html>.
62 ;; Browsers can cache Web pages so it may be necessary to tell them to
63 ;; reload the current page if it has changed (e.g. if you have edited
64 ;; it). There is currently no perfect automatic solution to this.
66 ;; Netscape allows you to specify the id of the window you want to
67 ;; control but which window DO you want to control and how do you
70 ;; William M. Perry's excellent "w3" WWW browser for
71 ;; Emacs <URL:ftp://cs.indiana.edu/pub/elisp/w3/>
72 ;; has a function w3-follow-url-at-point, but that
73 ;; doesn't let you edit the URL like browse-url.
74 ;; The `gnuserv' package that can be used to control it in another
75 ;; Emacs process is available from
76 ;; <URL:ftp://ftp.splode.com/pub/users/friedman/packages/>.
78 ;; Lynx is now distributed by the FSF. See also
79 ;; <URL:http://lynx.browser.org/>.
81 ;; Free graphical browsers that could be used by `browse-url-generic'
82 ;; include Chimera <URL:ftp://ftp.cs.unlv.edu/pub/chimera> and
83 ;; <URL:http://www.unlv.edu/chimera/>, Arena
84 ;; <URL:ftp://ftp.yggdrasil.com/pub/dist/web/arena> and Amaya
85 ;; <URL:ftp://ftp.w3.org/pub/amaya>. mMosaic
86 ;; <URL:ftp://ftp.enst.fr/pub/mbone/mMosaic/>,
87 ;; <URL:http://www.enst.fr/~dauphin/mMosaic/> (with development
88 ;; support for Java applets and multicast) can be used like Mosaic by
89 ;; setting `browse-url-mosaic-program' appropriately.
