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