  ${0##*/} is a Bash script to build UIX Lite's Icons.xbx.

  Usage: ${0##*/} OPTION

  OPTION:
    -a    Xbox's IP address.
          If only ogxbox's IP given, then the script will download default.xbes
          from all of the partitions.
          Specific directory is recommended for large disk, e.g.
          192.168.0.1/F/Games instead of just 192.168.0.1.
    -i    Local directory contains downloaded default.xbes.
          Use this to not redownloading the xbes from ogxbox.
          When -a and -i are provided, -i will be prioritized.
    -o    Output Icons.xbx.
          Default to script's working directory.
    -p    FTP password.
          Default to xbox.
    -u    FTP username.
          Default to xbox.
