# This launches Tor and starts an Onion service using Twisted and
# txtorcon, and then starts a Web server using the aiohttp library.
#
# This style of interop between asyncio and Twisted requires twisted
# to use the "asyncioreactor" and for code to convert Futures/Tasks to
# Deferreds (most of which is already in Deferred)
#
# Thanks to Mark Williams for the inspiration, and this code:
# https://gist.github.com/markrwilliams/bffb9c293194d105169ea06f03484ba1
#
# note: if run in Python2, there are SyntaxErrors before we can tell
# the user nicely
