  # to incorporate this file as a package using the following packages: configuration, and then overwrite these substitutions
  # in your local yaml file by redefining them.

  # on_hold_5s re-enables the AP and captive portal for the precompiled update binary.
  # any length of hold can be implemented with just on_press and on_release using the following directions.  This
  # is basically how this yaml file works.
  #   * have a delay for the desired hold in the on_press script
  #   * stop the on_press script in the on_release script
  #   * place actions in the on_press script after the delay to perform them while still holding the button
  #   * place actions in the on_release script, with the condition that the on_press script is not running, to 
  #     perform them on release of the button.
