Line 1: A list of all states in the finite automaton, separated by tabs.
Line 2: The transition alphabet, symbols separated by tabs. Do not explicitly state the epsilon transition symbol here.
Line 3: The start state of the finite automaton.
Line 4: The goal state(s) of the finite automaton, separated by tabs.
Line 5+: A list of all transition functions in the finite automaton. Use eps to indicate an epsilon transition. Each line is of the format: state, transition = new_state
