Documentation of Command Line Arguments
The documentation has information on command line arguments you can pass: https://www.eclipse.org/simopenpass/content/html/advanced_topics/simulator/simulation.html#command-line-arguments
In the documentation it says e.g.
–configs [configs] : Path for writing outputs (relative or absolute)
However, you have to provide
--configs [configs]. That is, two leading dashes are neccesary. This is very confusing.
