NIPyLL: Non-Intelligent Python Language-Learner

A Python emulation of the original NIALL (Non-Intelligent AMOS Language-
Learner).  NIPyLL receives conversational sentences from the user, builds
multisets recording which words follow other words.  NIPyLL then responds with
a chain of words, built using this information, often producing gibberish,
sometimes producing acceptable or amusing sentences.

Usage:    nipyll.py [ file ]
