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