• USE_GOOGLE_APPS := true – [1] Extract Google Apps from a gapps-passion package and install them into the system image.
  
• KITCHEN_BUILD := true – [2] Build a kitchen base system image. This will include absolutely no proprietary bits, including nothing from the dream ROM. This build is expected to be run after going through kitchen processing, with files written into it later.

Notes

1. A build with USE_GOOGLE_APPS := true defined is not legally redistributable in many countries due to proprietary rights held by Google on included binaries.
   
2. A build without KITCHEN_BUILD := true is not legally redistributable in many countries due to proprietary rights held by Qualcomm, HTC, or other companies on included binaries.
