# This shell script is a wrapper to launch the NDK build from the
# command-line inside an application project path.
#
# Typical usage is:
#
# cd $PROJECT_PATH
# ndk-build
#
# Assuming that the Android NDK root path is in your PATH. However,
# you can also invoke it directly as:
#
# $NDK_ROOT/ndk-build
#
# This really is a tiny wrapper around GNU Make.
#
# Ensure we get the full path of this script's directory
# this is needed if the caller uses the -C <path> GNU Make
# option, as in:
#
# cd ndk
# ./ndk-build -C <project-path>
#
PROGDIR=`dirname $0`
