+    Written by Harutyun Amirjanyan, (amirjanyan@gmail.com)
+
+    Based on code initially developed by: Einar Lielmanis, <einar@jsbeautifier.org>
+        http://jsbeautifier.org/
+
+    Usage:
+        css_beautify(source_text);
+        css_beautify(source_text, options);
+
+    The options are (default in brackets):
+        indent_size (4)                   — indentation size,
+        indent_char (space)               — character to indent with,
+        selector_separator_newline (true) - separate selectors with newline or
+                                            not (e.g. "a,\nbr" or "a, br")
+        end_with_newline (false)          - end with a newline
+
+    e.g
+
+    css_beautify(css_source_text, {
+      'indent_size': 1,
+      'indent_char': '\t',
+      'selector_separator': ' ',
+      'end_with_newline': false,
+    });
