-// This project demonstrates how to migrate a Windows desktop app to Native
-// Client, running first as a Win32 application (define STEP1), then as a PPAPI
-// plugin (define STEP2 through STEP6), and finally as a Native Client module.
-
-// Start with STEP1 defined and the defines for STEP2 through STEP6 commented
-// out.  For each step in the process, un-comment the next #define, leaving the
-// previous ones on.  Ready, set, port!
-
-// *** SELECT THE WIN32 PLATFORM AND RUN WITH #define STEP1 ONLY ***
-
-#define STEP1
-// Launches the original Windows desktop application, Hello World, which runs
-// as WinMain.  STEP1 encloses Windows-specific functions that are used with
-// the WIN32 and PPAPI platforms.  These will be removed when the full PPAPI
-// port is finished (STEP6)
-
-// *** SELECT THE PPAPI PLATFORM ***
-
-#define STEP2
-
-// Client Module.  STEP2 encloses the Native Client module APIs needed to link
-// any app to the browser.  The module does nothing except report
-// starting/ending the function Instance_DidCreate.  The Windows app does not
-// run because it is not being called.
-
-#define STEP3
-// What changed: Replace WinMain with WndProc, and call it from
-// Instance_DidCreate, launching hello_nacl_plus in its own window. Since
-// WndProc spins in its message loop, the call to Instance_DidCreate never
-// returns. Close the hello_nacl_plus window and the module initialization will
-// finish.
-
-#define STEP4
-// What changed: In WndProc replace the message loop with a callback function.
-// Now the app window and the Native Client module are running concurrently.
-
-#define STEP5
-// What changed: Instance_DidCreate calls initInstanceInBrowserWindow rather
-// than initInstanceInPCWindow. The initInstanceInBrowserWindow uses
-// postMessage to place text (now "Hello, Native Client") in the web page
-// instead of opening and writing to a window.
-
-#define STEP6
-// What changed: All the Windows code is def'd out, to prove we are
-// PPAPI-compliant.  The functional code that is running is the same as STEP5.
-
-// *** SELECT THE NACL64 PLATFORM AND RUN ***
-
-// What changed: The code is the same as STEP6, but you are using the SDK
-// toolchain to compile it into a nexe.  The module is now running as a real
-// Native Client executable in a NaCl sandbox, with nacl-gdb attached.
-
-// *** RUN YOUR MODULE IN THE WILD ***
-// You can run your nexe outside of Visual Studio, directly from Chrome by
-// following these steps:
-// - Build STEP6 and verify the file
-//   <project directory>/newlib/hello_nacl_plus/hello_nacl_plus.nexe exists
-// - Copy the folder <project directory>/hello_nacl_plus into your NaCl SDK's
-//   example directory.
-// - Go to the NaCl SDK directory and launch the httpd.py server.
-// - Launch Chrome, go to about:flags and enable the Native Client flag and
-//   relaunch Chrome
-// - Point Chrome at localhost:5103/hello_nacl_plus
