It is similar to the recently released PS3 PKGView and UnPKG file extractors / unpackers, and to use it simply click the big button and select your PKG file.
To quote, roughly translated: "There is a similar procedure before the call PkgView.exe But the program can not bulk unpacked, unpack and often wrong.
The device can be quickly unpacked all the files once unpacked. Self-made program can only unpack and debug pkg. Can not unpack the pkg downloaded from the official PSN."
