# This script makes you choose 1 out of 2 Oulipo constraints:

# Constraint 1: http://oulipo.net/fr/contraintes/litterature-definitionnelle
# Constraint 2: rewrites the beginning of a novel by replacing the principal names/places/gender
# The idea for this script comes from the book 'Think Python'.
