#   Note:
#
#   This file is used to build HarfBuzz within the Android
#   platform itself.  If you need to compile HarfBuzz to
#   ship with your Android NDK app, you can use the autotools
#   build system to do so.  To do that you need to install a
#   "standalone" toolchain with the NDK, eg:
#
#       ndk/build/tools/make-standalone-toolchain.sh \
#           --platform=android-18 \
#           --install-dir=/prefix
#
#   Set PLATFORM_PREFIX eng var to that prefix and make sure
#   the cross-compile tools from PLATFORM_PREFIX are in path.
#   Configure and install HarfBuzz:
#
#       ./configure --host=arm-linux-androideabi \
#           --prefix=$PLATFORM_PREFIX \
#           --enable-static \
#           --with-freetype \
#           PKG_CONFIG_LIBDIR=$PLATFORM_PREFIX/lib/pkgconfig
#       make install
#
#   You can first build FreeType the same way:
#
#       ./configure --host=arm-linux-androideabi \
#           --prefix=$PLATFORM_PREFIX \
#           --enable-static \
#           --without-png \
#           PKG_CONFIG_LIBDIR=$PLATFORM_PREFIX/lib/pkgconfig
#       make install
#
