psdev just released (well not recently) a very simple and useful script for psv users
wiki: Playstation Update Package (PUP) - Vita Dev Wiki
this script is used for nvestigating the PS Vita PUP files (PlayStation Update Package). This script will give you some basic information about the package header, as well as extract the license file. Magic Reader might be useful for those of you who are too lazy to understand the information provided from PSVITADEV WIKI.
INSTALLATION:
Extract, and to run, just type ./magic.sh PSP2UPDAT.PUP (assuming the PUP file you want to analyze is called PSP2UPDAT.PUP) . The files will run on CYGWIN as-well, if you donít have Linux
DOWNLOAD:
