I see -- and it's not possible to draw them in as standard Maven
dependencies for the correct platforms? I think this works with other
Java-C-bridging libraries such as OpenCV, for example:
http://search.maven.org/#search%7Cga%7C1%7Copencv
you have there linux-armhf.jar, linux-x86.jar, linux-x86_64.jar,
macosx-x86_64.jar, windows-x86.jar etc.
would it be possible to do that with NetCDF as well?
best, .h.h.
