Usage: sudo $0 [options]

This script installs a (commercial) NKN node on a Raspberry Pi.
If a dedicated mining user should be created, provide their name and password.
Otherwise, installation will be done for the current user.

Options:
  -a arch    ARM architecture (armv7 or arm64)                 [armv7]
  -u name    name of NKN mining user                           [current user]
  -p secret  password of new NKN mining user                   []
  -b addr    NKN wallet address for mining rewards
  -w dir     directory that contains existing wallet.json and wallet.pswd to be used
  -d dir     deployment directory relative to mining user home [nkn-commercial-node]
  -h         print this help message
