# Homework 4: Assassin, in Python

# Instructor-provided testing program.

# AssassinMain is the main client program for assassin game management.
# It reads names from a file names.txt, shuffles them, and uses them to
# start the game.  The user is asked for the name of the next victim until
# the game is over.

# If not random, use this value to guide the sequence of numbers
# that will be generated by the random number generator.

# Handles the details of recording one victim.  Shows the current kill
# ring and graveyard to the user, prompts for a name and records the
# kill if the name is legal.
