Empire uses certain conventions for input and output control.
When a response has a default value, pressing return is equivalent
to entering the default value. Control Y should terminate any
command and return you to the main prompt. For many questions
entering a zero '0' is the same as pressing control Y. Double
slashes "//" mean back up to the previous question. If you are
at the first question, // will back you up to the main prompt.
If you are uncertain as to what would be a valid response to
any question, enter a question mark "?". There may not be
specific help text (often there is) but the error message should
explain what the question is expecting.
Only the minimum portion of commands and keywords are generally
required to execute a command.
