-$ tools/retrolambda.sh build/libs/AppleCommander-ac-<version>.jar
-Converting...
-Retrolambda 2.5.6
-Repackaging to build/libs/AppleCommander-ac-<version>-java5.jar
-```
-
-This will:
-1. Create the `build` directory and populate with uber-jars in `build/libs`.
-2. Create a Java 5 variant of the `ac` tool in `AppleCommander-ac-<version>-java5.jar`. (Replace `<version>` with version.) 
-
-To run the command-line version of AppleCommander, use the following:
-
-* All platforms:
-  `java -jar build/libs/AppleCommander-ac-VERSION.jar`
-* Java 5:
-  `java -jar build/libs/AppleCommander-ac-VERSION-java5.jar`
-
-To launch the GUI version of AppleCommander, use the following:
-
-* Linux:
-  `java -jar build/libs/AppleCommander-linux64-gtk-VERSION.jar`
-* Windows:
-  `java -jar build/libs/AppleCommander-win64-VERSION.jar`
-* Mac OS X:
-  `java -XstartOnFirstThread -jar build/libs/AppleCommander-macosx-VERSION.jar`

-## Raspberry Pi Notes
-
-Available versions found are: `3.8` and `4.6`. `4.6` failed with a JNI issue.
-
-Retrieve libraries:
-
-```
-$ sudo apt install libswt-gtk-3-java libswt-gtk-3-jni
-```
-
-Combine into one JAR (`-j` drops the directories from `*.so` files in the zip file):
-
-```
-$ cp /usr/lib/java/swt-gtk-3.8.2.jar org.eclipse.swt.gtk.linux.arm-3.8.2.jar
-$ zip -j org.eclipse.swt.gtk.linux.arm-3.8.2.jar /usr/lib/jni/libswt-*3836*.so 
-```
-
-Preserve JAR file in `rpi-lib`!  If the file name is incorrect, the build process will show the expected filename in the error message...
-
-Error for 4.6:
-
-```
