 ## Components
 The output consists of these parts:
 * JRE running on the EV3 - `jre-ev3.zip`
   * Stripped down version -- a runtime image
 * JDK built for the EV3 - `jdk-ev3.zip`
   * Basically the full build

   * Only a stripped down version -- also a runtime image
   * It can be used for creating custom JRE images. For this, jlink and the ev3 jmods are included.
   * It has `javac` (jdk.compiler module).
