Known Issues here:
1. First of all, our infrastructure for command line interface is very frustrating: Some command line options are
   passed down, but others not. No consistency, no documentation. To figure out, you have to trial-and-error. And
   mind you, your current learnings might not hold for the future.
2. There currently seems no way to get the -OPLSDIR option value. It's neigther passed down nor set in an environment
   variables.
