Compile

• You'll need docopt. The build script expects to find it at ../docopt.java/target/docopt-0.6.0-SNAPSHOT.jar, adjust to fit your environment.
• gradle jar
• gradle createRpm. The RPM is very basic, it contains a wrapper script that supports MacOS and Linux. On Linux, the script expects java to be managed by the alternatives system (see here).
