  Answer the following questions to setup this RHQ Agent instance.

  If you press the ENTER key without providing any value,
  the new preference value will be set to that default value.
- If you wish to rely on the system internal default value and
  not define any preference value, enter '!*'.
- If you wish to stop before finishing all the questions but still
  retain those preferences you already set, enter '!+'.
- If you wish to cancel before finishing all the questions and revert
  all preferences back to their original values, enter '!-'.
- If you need help for a particular preference, enter '!?'.
