The only problem with this resulting code is that setup_path_on_import
only works if the Python versions are the same, so you need to run
this with Python 3 in that case.
We try to resolve that for use on Zulip servers with
zulip/zulip:47c5aae5b242fb6d2f5e860602e0fc0af68419bb; since that's the
main case where the code path runs, that should be good enough.
These were quite messy code, and now that almost nobody is running
their own zephyr mirroring script (vs. using webathena), making the
zephyr mirroring script deployable outside the package isn't super
valuable.
To do so, we need to import all required internal modules after the
script had the option to provision. The provisioning itself is then
done by zulip.init_from_options().
I'm not thrilled with the `replace` error handler losing information
if the logfile contains invalid UTF-8 for some reason; but that sure
beats a UnicodeDecodeError, and for this script I can't quite be
bothered to run the rather tricky riddle trail that Python 3 makes it
to pass arbitrary byte data through layers of ordinary text processing.
In order to keep all three packages (zulip, zulip_bots,
zulip_botserver) in the same repo, all package files must now
be nested one level deeper.
For instance, python-zulip-api/zulip_bots/zulip_bots/bots/, instead
of python-zulip-api/zulip_bots/bots/.
