 In addition to learning a new appreciation for fire, you've also made water...
 And while dusting off your C/C++ image manipulation skills,
 you've discovered how easy it is to modify, build,
 and run a NaCl application that uses PPAPI.
 
 2D graphics is fun, but now you're ready to check out the wealth of
 other
 `PPAPI interfaces available

 While our in-browser environment is rapidly evolving
 to become a complete development solution,
 for the broadest range of development options, check out the
 `NaCl SDK

 I hope this codelab has lit a fire in you to go out there,
 and bring an awesome C/C++ application to NaCl or PNaCl today!
