+       within a display generated by the Derivative Works, if and
+       wherever such third-party notices normally appear. The contents
+       of the NOTICE file are for informational purposes only and

+   defend, and hold each Contributor harmless for any liability
+   incurred by, or claims asserted against, such Contributor by reason
+   of your accepting any such warranty or additional liability.

+// less.js - parser
+//
+//    A relatively straight-forward predictive parser.
+//    There is no tokenization/lexing stage, the input is parsed
+//    in one sweep.
+//
+//    To make the parser fast enough to run in the browser, several
+//    optimization had to be made:
+//
+//    - Matching and slicing on a huge input is often cause of slowdowns.
+//      The solution is to chunkify the input into smaller strings.
+//      The chunks are stored in the `chunks` var,
+//      `j` holds the current chunk index, and `current` holds
+//      the index of the current chunk in relation to `input`.
+//      This gives us an almost 4x speed-up.
+//
+//    - In many cases, we don't need to match individual tokens;
+//      for example, if a value doesn't hold any variables, operations
+//      or dynamic references, the parser can effectively 'skip' it,
+//      treating it as a literal.
+//      An example would be '1px solid #000' - which evaluates to itself,
+//      we don't need to know what the individual components are.
+//      The drawback, of course is that you don't get the benefits of
+//      syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+//      and a smaller speed-up in the code-gen.
+//
+//
+//    Token matching is done with the `$` function, which either takes
+//    a terminal string or regexp, or a non-terminal function to call.
+//    It also takes care of moving all the indices forwards.
+//

+        //      > .child {...}

+        //     Ruleset (Selector '.class', [
+        //         Rule ("color",  Value ([Expression [Color #fff]]))

+        //
+        //  In general, most rules will try to parse a token with the `$()` function, and if the return
+        //  value is truly, will return a new node, of the relevant type. Sometimes, we need to check

+/***********************************************************************
+
+  A JavaScript tokenizer / parser / beautifier / compressor.
+
+  This version is suitable for Node.js.  With minimal changes (the
+  exports stuff) it should work on any JS platform.
+
+  This file contains the tokenizer/parser.  It is a port to JavaScript
+  of parse-js [1], a JavaScript parser library written in Common Lisp
+  by Marijn Haverbeke.  Thank you Marijn!
+
+  [1] http://marijn.haverbeke.nl/parse-js/
+
+  Exported functions:
+
+    - tokenizer(code) -- returns a function.  Call the returned
+      function to fetch the next token.
+
+    - parse(code) -- returns an AST of the given JavaScript code.

+/***********************************************************************
+
+  A JavaScript tokenizer / parser / beautifier / compressor.
+
+  This version is suitable for Node.js.  With minimal changes (the
+  exports stuff) it should work on any JS platform.
+
+  This file implements some AST processors.  They work on data built
+  by parse-js.
+
+  Exported functions:
+
+    - ast_mangle(ast, options) -- mangles the variable/function names
+      in the AST.  Returns an AST.
+
+    - ast_squeeze(ast) -- employs various optimizations to make the
+      final generated code even smaller.  Returns an AST.
+
+    - gen_code(ast, options) -- generates JS code from the AST.  Pass
+      true (or an object, see the code for some options) as second
+      argument to get "pretty" (indented) code.
