A tool to automate user account creation and initial balance setting.

THIS TOOL MUST NOT BE USED IF YOU WANT TO LIMIT YOUR USERS BY PAGE QUOTA !

command line usage :

  THIS TOOL MUST NOT BE USED FROM THE COMMAND LINE BUT ONLY AS PART
  OF AN external policy IN pykota.conf
  
  autopykota { -i | --initbalance value } 

options :

  -v | --version       Prints autopykota's version number then exits.
  -h | --help          Prints this message then exits.
  
  -i | --initbalance b Sets the user's account initial balance value to b.
                       If the user already exists, actual balance is left
                       unmodified. If unset, the default value is 0.
