                        Minimum length of words used in the passphrase. 
                        Must be an integer value between 1 and 8. 
                        Defaults to 1
  --separators [SEPARATORS ...], -s [SEPARATORS ...]
                        List of separators to separate words in the passphrase.

                        0 -> kebab-case (default)
                        1 -> PascalCase
                        2 -> InTermitteNt CapItalIzaTIon
                        3 -> StIcKy CaPs
  --num_passphrases NUM_PASSPHRASES, -n NUM_PASSPHRASES
                        The number of passphrases to be generated from the acronym.
