>Derek Smith has released MacSFV 1.3, an update to his RAR package 
>verification program that "has been rewritten entirely in Cocoa with 
>Apple's Project Builder and can scan packages up to 20% than the 
>MacOS 9 classic application. MacSFV is used to verify complete RAR 
>sets and to identify bad or missing individual files in a set." It
