File: js.el.html

This is based on Karl Landstrom's barebones javascript-mode. This is much more robust and works with cc-mode's comment filling
(mostly).

The main features of this JavaScript mode are syntactic highlighting (enabled with font-lock-mode(var)/font-lock-mode(fun) or global-font-lock-mode(var)/global-font-lock-mode(fun)), automatic indentation and filling of comments, C preprocessor fontification, and MozRepl integration.

General Remarks:

XXX: This mode assumes that block comments are not nested inside block XXX: comments

Exported names start with "js-"; private names start with
"js--".
