  This script provides badoo executor scheduler. Delay is set to "${DELAY_BETWEEN_RUN}" seconds between run.

  Please use next commands:
    - 'counted-executor' to run executor certain amount of time e.g '100'
    - 'infinite-executor' to run executor infinite period of time (it will run until script is crashed)
    - 'infinite-executor-background' to run executor infinitely in a background.
       Logs will be saved in '${LOGS}' file automatically

  Please see '${LOGS}' file for additional logs info.
