Notes

1. Patterns
    * Words
        * `W`: WORD
        * `w`: word
        * `T`: Word
        * `k`: `shuffle(cccc(c|d)(C|c))`
        * `{sub}`: see `WordKind`s section in readme
    * Characters
        * `C`: A-Z
        * `c`: a-z
        * `d`: 0-9
        * `s`: `~!@#$%^&*-_=+;:,./?()[]{}<>`
        * `a`: `C` | `c` | `d` | `s`
    * Special
        * `keychain`
        * `codename`
        * `codename-series`
        * `haiku--` | `haiku-condensed`
        * `haiku-` | `haiku-with-syllables-condensed`
        * `haiku`
        * `haiku+` | `haiku-with-syllables`
        * `haiku++` | `haiku-full`
        * `haiku+++` | `haiku-full-with-syllables`

2. Ten attempts are made to satisfy the given length requirements by default;
   use `-a N` and set `N` to the number of attempts to increase chances.
   It will exit with an error if unable to satisfy requirements; some
   configurations will always produce an error.

3. Extended words are only available in exclusively extended word kinds by
   default; however, with `-e`, they are merged with regular word kinds; use
   with the `-L` option to see its effect.

Notes

  1. WordKind / {sub}

  2. It is only necessary to set the most descriptive WordKind(s) since they are automatically included in the larger word kinds.

  3. The characters object value must contain the C, c, and d keys with non-empty values. Additional keys/values can be added and used.

  4. {sub}s produce lowercase words by default, but if prefixed with W: or T: words will be uppercase or title case, respectively: i.e. {W:sub} or {T:sub} (replace sub with an actual {sub} name above).

  5. {sub}s include all words by default, but if suffixed with :N where N is a number, it will only include words with that number of syllables: i.e. {sub:N} (replace sub with an actual {sub} name above and N with the desired number of syllables ~1-5).
