# a very simple eliza-like program
#
# 1) greet user
# react if user doesn't greet Eliza
# 2) repeat a huge number of times:
# 2.1) get user's statement about life
# 2.2) do a reflexion first to second person
# by replacing I by you, me by you,
# mine by yours, my by your, etc...
# and also 2nd to first person
# 2.3) figure out what to print
# if the user's sentence is in the form 'I xxxx you', ask why
# if there are key words, print a random family related sentence
# if the sentence was reflected, then print it
# if the sentence contained no or never, then
# react to it
# otherwise, just a random canned sentence
#
import random
from logging111 import Print
from logging111 import Raw_input
#Note: if you do not have a logging111.py module, simply replace
# Print by print, and Raw_input by raw_input is the program, and it
# should work fine.
