Hi Ron,
Since you are a programmer, please consider to join our small LC team and improve it.
Our source code is mostly clean, and we are happy to assist when it's not that clean in source code.
You can also help improve our user manual/wiki, etc.
Back to your question, you can find available command line support here:
