 // 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.

 // *** 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>/NaCl64/newlib/Debug/hello_nacl_64.nexe exists
 // - Copy the folder <project directory> 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
