Better documented options?

[trevtravtrev]

Could we get better documented options in the readme? These options, while helpful, are quite vague and after tinkering with them I'm quite unsure what most do.

options:
  -h, --help            show this help message and exit
  -i, --interactive     run in interactive mode
  --interactive-start   run in interactive mode and poll user input at startup
  -r PROMPT, --reverse-prompt PROMPT
                        in interactive mode, poll user input upon seeing PROMPT
  --color               colorise output to distinguish prompt and user input from generations
  -s SEED, --seed SEED  RNG seed (default: -1)
  -t N, --threads N     number of threads to use during computation (default: 4)
  -p PROMPT, --prompt PROMPT
                        prompt to start generation with (default: random)
  -f FNAME, --file FNAME
                        prompt file to start generation.
  -n N, --n_predict N   number of tokens to predict (default: 128)
  --top_k N             top-k sampling (default: 40)
  --top_p N             top-p sampling (default: 0.9)
  --repeat_last_n N     last n tokens to consider for penalize (default: 64)
  --repeat_penalty N    penalize repeat sequence of tokens (default: 1.3)
  -c N, --ctx_size N    size of the prompt context (default: 2048)
  --temp N              temperature (default: 0.1)
  -b N, --batch_size N  batch size for prompt processing (default: 8)
  -m FNAME, --model FNAME
                        model path (default: ggml-alpaca-7b-q4.bin)
