# 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.
