usage: CDNSP.py [-h] [-i TID [TID ...]] [-g TID-VER-TKEY [TID-VER-TKEY ...]]
                [-s VER [VER ...]] [-r]

optional arguments:
  -h, --help                          show this help message and exit
  -i TID [TID ...]                    print info about a title:
                                         - name from shogun
                                         - available updates from versionlist
  -g TID-VER-TKEY [TID-VER-TKEY ...]  download games/updates/DLC's:
                                         - titlekey argument is optional
                                         - format TitleID-Version(-Titlekey)
                                         - update TitleID's are the same as the base game's,
                                           with the three last digits replaced with '800'
                                         - version is 0 for base games, multiple of 65536 (0x10000) for updates
  -s VER [VER ...]                    download system updates:
                                         - version is computed as follows (credit goes to SocraticBliss):
                                         - X.Y.Z-B (all decimal integers)
                                           => VER = X*67108864 + Y*1048576 + Z*65536 + B
                                                 (= X*0x4000000 + Y*0x100000 + Z*0x10000 + B)
                                         - 0 will download the lastest update
  -r                                  repack the downloaded games to nsp format
                                         - for non-update titles, titlekey is required to generate tik
                                         - will generate/download cert, tik and cnmt.xml
