Usage: $(basename "$0") [OPTIONS]

This script processes files with specified options.

Options:
  -h, --help    Display this help message and exit.
  -c, --context <value>    Set context length. Bigger need more memory.
  -p, --promote <value>    Prompt to start generation with.
  -m, --model   <value>    Full model file path.
  -mg,--main-gpu <value>   Set main GPU ID (0 - n) for single GPU mode.
  -sm,--split-mode <value> How to split the model across multiple GPUs, one of:
                            - none: use one GPU only
                            - layer (default): split layers and KV across GPUs
                            - row: split rows across GPUs
  -ngl,--n-gpu-layers <value>  Max. number of layers to store in VRAM (default: -1)
  -lv,--log-verbosity <value>  Set the verbosity threshold. Messages with a higher verbosity will be
                               ignored. Values:
                                - 0: generic output
                                - 1: error
                                - 2: warning
                                - 3: info
                                - 4: debug
