# Demonstration example that Craig DeLancey made up all by himself.
# 
# This stuff with a hashtag is all comments, where you can
# explain how your machine's tape should be set.  For example
# I might write:
#
# This addition machine adds two numbers represented in unary
# as a series of 1s, separated by a single space. The machine
# starts on the leftmost 1 of the left number. The machine ends
# under the the leftmost 1 of the answer number.  It is designed
# only to handle two numbers greater than zero.
# 
# What you write here with the hashtag to the left is
# ignored by Tursi.  Programmers call this a "comment."
# 
# The rules below (at the bottom) are listed always in the order:
# In-State    Reading-Symbol   Write-state   Move-Direction   Go-Into-State
# 
# So, that first line means: in state 0, reading 1 on the tape,
# write a 1 on the tape, and move right, and go into state 0.
# 
# Remember that you can put something on the tape in Tursi
# by writing in that box below the word "Tape", and then hit return.
#
# These lines immediately below, with hash-tag and exclamation point
# to the left, allow one to tell the machine which state to start 
# with, and which state to end on.
# 
#! start 0
#! end H
