- * @fileoverview Enhances <a href="https://github.com/mishoo/UglifyJS/"
- * >UglifyJS</a> with consolidation of null, Boolean, and String values.
- * <p>Also known as aliasing, this feature has been deprecated in <a href=
- * "http://closure-compiler.googlecode.com/">the Closure Compiler</a> since its
- * initial release, where it is unavailable from the <abbr title=
- * "command line interface">CLI</a>. The Closure Compiler allows one to log and
- * influence this process. In contrast, this implementation does not introduce
- * any variable declarations in global code and derives String values from
- * identifier names used as property accessors.</p>
- * <p>Consolidating literals may worsen the data compression ratio when an <a
- * href="http://tools.ietf.org/html/rfc2616#section-3.5">encoding
- * transformation</a> is applied. For instance, <a href=
- * "http://code.jquery.com/jquery-1.7.1.js">jQuery 1.7.1</a> takes 248235 bytes.
- * Building it with <a href="https://github.com/mishoo/UglifyJS/tarball/v1.2.5">
- * UglifyJS v1.2.5</a> results in 93647 bytes (37.73% of the original) which are
- * then compressed to 33154 bytes (13.36% of the original) using <a href=
- * "http://linux.die.net/man/1/gzip">gzip(1)</a>. Building it with the same
- * version of UglifyJS 1.2.5 patched with the implementation of consolidation
- * results in 80784 bytes (a decrease of 12863 bytes, i.e. 13.74%, in comparison
- * to the aforementioned 93647 bytes) which are then compressed to 34013 bytes
- * (an increase of 859 bytes, i.e. 2.59%, in comparison to the aforementioned
- * 33154 bytes).</p>

- * of <a href="http://es5.github.com/">ECMA-262 5.1 Edition</a>. Encoded in <a
- * href="http://tools.ietf.org/html/rfc3629">UTF-8</a>. Follows <a href=

-
-  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.
