-/// These functions are stand-ins for your complicated computations which you
-/// want to run in native code.  We do two very simple things:  return 42, and
-/// reverse a string.  But you can imagine putting more complicated things here
-/// which might be difficult or slow to achieve in JavaScript, such as
-/// cryptography, artificial intelligence, signal processing, physics modeling,
-/// etc.  See hello_world.cc for the code which is required for loading a NaCl
-/// application and exposing methods to JavaScript.
