[alan-agius4]

You should use the arguments with a double dash, example --aot

@alan-agius4 Oh wow... I tried so many things without realizing it. I think the confusion came from using the -o flag along with the other. Sorry!

EDIT: I copy-pasted the flag from an older project. Perhaps it's changed.
