Usage: spit [OPTION...]

Passes standard input to a Large Language Model (LLM) instance and prints
the response.
With the --to option, it translates standard input to the specified language
through a Large Language Model (LLM) and prints the translation.

Warning: The output might not be what you expect.
It might be of the wrong form, be of poor quality, or reflect some biases.

Options:
      --species=TYPE          Specifies the type of LLM.  The default and only
                              valid value is 'ollama'.
      --url=URL               Specifies the URL of the server that runs the LLM.
  -m, --model=MODEL           Specifies the model to use.
      --to=LANGUAGE           Specifies the target language.
      --prompt=TEXT           Specifies the prompt to use before standard input.
                              This option overrides the --to option.
      --postprocess=COMMAND   Specifies a command to post-process the output.

Informative output:

  -h, --help                  Display this help and exit.
  -V, --version               Output version information and exit.
