- -c
only print statistics if a key other than `q' is pressed
- -r
enable rewriting of dictionary words (see rules below)
- -w <num>
number of threads to run with.
- -b <size>
size of the word list buffer
- -u <user>
user account to su to
- -l <rules>
specify certain rules for the rewriting process
- Rewriting rules:
- A
Rewrite word with only upper case characters
- F
Rewrite word with first character as upper case
- L
Rewrite word with last character as upper case
- a
Rewrite word with only lower case characters
- f
Rewrite word with first character as lower case
- l
Rewrite word with last character as lower case
- D
Prepend each digit (0-9) to the word
- d

- e

- x
apply all rules to a word
