     17 #  This shell script is a wrapper to launch the NDK build from the
     18 #  command-line inside an application project path.
     19 #
     20 #  Typical usage is:
     21 #
     22 #     cd $PROJECT_PATH
     23 #     ndk-build
     24 #
     25 #  Assuming that the Android NDK root path is in your PATH. However,
     26 #  you can also invoke it directly as:
     27 #
     28 #     $NDK_ROOT/ndk-build
     29 #
     30 #  This really is a tiny wrapper around GNU Make.
     31 #
     32 
     33 # Ensure we get the full path of this script's directory
     34 # this is needed if the caller uses the -C <path> GNU Make
     35 # option, as in:
     36 #
     37 #    cd ndk
     38 #    ./ndk-build -C <project-path>
