+/***********************************************************************
+
+ 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.
