Right command-line parameters (prompt etc.) for orca-mini-3B in interactive mode

[hfassold]

I want to use the orca-mini-3B model in interactive mode (chat mode) for question answering.

Specifically, I use the quants at
https://huggingface.co/Aryanne/Orca-Mini-3B-gguf
which are derived from the HF model at
https://huggingface.co/pankajmathur/orca_mini_3b

The doc for the HF model states that the right prompt is the following:
"### System:\n{system}\n\n### User:\n{instruction}\n\n### Response:\n"

What is the right way to call the llam.cpp executable ('main') so that it uses exactly this prompt (and is in interactive mode) ?
