     29 
     30 This script builds libportable.a for app link with portable header.
     31 
     32 This requires a platform.git/development and a temporary NDK installation
     33 containing platforms and toolchain binaries for all target architectures.
     34 
     35 By default, this will try with the current NDK directory, unless
     36 you use the --ndk-dir=<path> option.
     37 
     38 The output will be placed in appropriate sub-directories of
     39 <ndk>/$LIBPORTABLE_SUBDIR, but you can override this with the --out-dir=<path>
     40 option.
