# build-platforms.sh
#
# This tool is used when packaging a new release, or when developing
# the NDK itself. It will populate DST ($NDK/platforms by default)
# with the content of SRC ($NDK/../development/ndk/platforms/ by default).
#
# The idea is that the content of $SRC/android-N/ only contains stuff
# that is relevant to API level N, and not contain anything that is already
# provided by API level N-1, N-2, etc..
#
# More precisely, for each architecture A:
#  $SRC/android-N/include        --> $DST/android-N/arch-A/usr/include
#  $SRC/android-N/arch-A/include --> $DST/android-N/arch-A/usr/include
#  $SRC/android-N/arch-A/lib     --> $DST/android-N/arch-A/usr/lib
#
# For backwards compatibility:
#  $SRC/android-N/arch-A/usr/include --> $DST/android-N/arch-A/usr/include
#  $SRC/android-N/arch-A/usr/lib     --> $DST/android-N/arch-A/usr/lib
#
# Repeat after that for N+1, N+2, etc..
