This is a reminder for myself more than anything.
To learn what you can do with an application using osascript, you can run Script Editor and click “Open the Application’s Dictionary” to see properties &/methods that are available.
Quick script to decompile all the class files.
find . -name "*.class" -not -name "*\$*" | while read class
do
dir=`dirname $class`
file=`basename $class .class`
pushd $dir >/dev/null
jad -p ${file}.class > ${file}.java
popd >/dev/null
done
