# We want to run mitmproxy with our script as an addon. A simple way would be to
# find something like a 'main' function in mitmproxy, import it and call here.
# Unfortunately, there is currently no guarantee that such function can be
# considered mitmproxy's stable programming API. For this reason we instead
# spawn a new process.

# The following import requires at least Python 3.8. There is no point adding
# a workaround for Python 3.7 because mitmproxy itself (which we're loading
# here) relies on Python 3.9+. This does not affect the Hydrilla server and
# builder which continue to work under Python 3.7.
