/**
 * @brief tool to access the system config from the CLI
 *
 * With this script you can access the system configuration of your node from
 * the CLI. You can do both, reading current values stored in the database and
 * set new values to config variables.
 *
 * Usage:
 *   If you specify no parameters at the CLI, the script will list all config
 *   variables defined.
 *
 *   If you specify one parameter, the script will list all config variables
 *   defined in this section of the configuration (e.g. "system").
 *
 *   If you specify two parameters, the script will show you the current value
 *   of the named configuration setting. (e.g. "system loglevel")
 *
 *   If you specify three parameters, the named configuration setting will be
 *   set to the value of the last parameter. (e.g. "system loglevel 0" will
 *   disable logging)
