-
-  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.
