# This is a metapackage which pulls in the dependencies. There are two main
# installation scenarios:

# 1) We get installed from PyPi from our own sdist. In this case we need to
# declare dependencies on the released PyPi packages.

# 2) We get run from the root of the source tree (e.g. checked out from git). In
# this case we need to declare the setup.py as a dependency so it gets installed
# first.
