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+`
* `haiku-`
* `haiku--`

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).
