statistics display intervall (requires --enable-statistics configuration flag)
-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
