# In short, this provisions a Zulip development environment and then
# builds a Zulip release tarball (the same way we build them for an
# actual release).  The actual test job will then install that.
#
# This script is more complicated than that, basically because Travis
# CI installs a ton of crap in its build workers, and we need to
# remove some and reconfigure others to make things run smoothly and
# quickly.
