A Discord Bot with asyncio

Following last year’s article on Slack, here is how to create a bot for Discord. We will go through a minimalist bot that does close to nothing. Most of the provided examples using libraries like discord.py hide asyncio away. Here we will make it explicit how it works under the hood. Be aware that this is not the easiest way to build a bot but a step-stone to understand what complete libraries do for you.

	some special magic rules which are altering the context. E.g. french puts a
	space before the colon (:).
