 # Build the Android libraries without needing a project

 # (AndroidManifest.xml, jni/{Application,Android}.mk, etc.)

 #

 # Usage: androidbuildlibs.sh [arg for ndk-build ...]"

 #

 # Useful NDK arguments:

 #

 #  NDK_DEBUG=1          - build debug version

 #  NDK_LIBS_OUT=<dest>  - specify alternate destination for installable

 #                         modules.

 #

 # Note that SDLmain is not an installable module (.so) so libSDLmain.a

 # can be found in $obj/local/<abi> along with the unstripped libSDL.so.

 #

 # Android.mk is in srcdir

 srcdir=`dirname $0`/..
