+ JS Beautifier
+---------------

+ Originally converted to javascript by Vital, <vital76@gmail.com>
+
+ You are free to use this in any way you want, in case you find this useful or working for you.
+
+ Usage:
+ js_beautify(js_source_text);
+ js_beautify(js_source_text, options);
+
+ The options are:
+ indent_size (default 4) — indentation size,
+ indent_char (default space) — character to indent with,
+ preserve_newlines (default true) — whether existing line breaks should be preserved,
+ indent_level (default 0) — initial indentation level, you probably won't need this ever,
+
+ space_after_anon_function (default false) — if true, then space is added between "function ()"
+ (jslint is happy about this); if false, then the common "function()" output is used.
+
+ e.g
+
+ js_beautify(js_source_text, {indent_size: 1, indent_char: '\t'});
