The current ant file basically only works on my computer as it seems,
because it was generated from my copy of IntelliJ IDEA. I have edited
it, though, to add the creation of the Jar and the required Premain-
Class line in the manifest file.
I'm not very proficient in Ant files - maybe it's time I learned but I
just can't bring myself to it. Anyone here with knowledge on how to
parameterise an ant file in a way that it will find the JDK location
itself, etc?
