John the ripper

Hi guys, Does anyone know how to, if I interrupted john with ctrl+C, let it resume where it stopped? I accidently stopped it (wrong console...) after about two weeks of running on a 3ghz Xeon - not keen to start over. Googling found only one possibility - a -resume switch, but john tells me it's an unknown option. Thanks -- Hans du Plooy SagacIT (Pty) Ltd hansdp at sagacit dot com
