+
+ JS Beautifier
+---------------
+
+
+  Written by Einar Lielmanis, 
+      http://jsbeautifier.org/
+
+  Originally converted to javascript by Vital, 
+  "End braces on own line" added by Chris J. Shull, 
+  Parsing improvements for brace-less statements by Liam Newman 
+
+
+  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,
+    max_preserve_newlines (default unlimited) - maximum number of line breaks to be preserved in one chunk,
+
+    jslint_happy (default false) - if true, then jslint-stricter mode is enforced.
+
+            jslint_happy        !jslint_happy
+            ---------------------------------
+            function ()         function()
+
+            switch () {         switch() {
+            case 1:               case 1:
+              break;                break;
+            }                   }
+
+    space_after_anon_function (default false) - should the space before an anonymous function's parens be added, "function()" vs "function ()",
+          NOTE: This option is overriden by jslint_happy (i.e. if jslint_happy is true, space_after_anon_function is true by design)
+
+    brace_style (default "collapse") - "collapse" | "expand" | "end-expand"
+            put braces on the same line as control statements (default), or put braces on own line (Allman / ANSI style), or just put end braces on own line.
+
+    space_before_conditional (default true) - should the space before conditional statement be added, "if(true)" vs "if (true)",
+
+    unescape_strings (default false) - should printable characters in strings encoded in \xNN notation be unescaped, "example" vs "\x65\x78\x61\x6d\x70\x6c\x65"
+
+    wrap_line_length (default unlimited) - lines should wrap at next opportunity after this number of characters.
+          NOTE: This is not a hard limit. Lines will continue until a point where a newline would
+                be preserved if it were present.
+
+    end_with_newline (default false)  - end output with a newline
+
+
+    e.g
+
+    js_beautify(js_source_text, {
+      'indent_size': 1,
+      'indent_char': '\t'
+    });
