 # This script is used to generate .gypi files needed to build libvpx.
 # Every time libvpx source code is updated just run this script.
 #
 # For example:
 # $ ./generate_gypi.sh
 #
 # And this will update all the .gypi files needed.
 # However changes to asm_*_offsets.asm, vpx_config.asm and
 # vpx_config.h are not updated and needs to modified manually
 # for all platforms.
