From the doc: 'This program is intended for
finding forgotten passwords to RAR archives of
versions 2.XX. The program finds by the method of
exhaustive search all possible combinations of
characters ('bruteforce' method) or/and using
passwords from a list ('wordlist' or 'dictionary'
method). The program is able to save the current
state of operation. The skilful configuring allows
to perform parallel processing. The process with
selfextracting archives (SFX) and multivolume
archives is supported.'
