# Useful global ipapi object and main IPython one. Unfortunately we have a
# long precedent of carrying the 'ipapi' global object which is injected into
# the system namespace as _ip, but that keeps a pointer to the actual IPython
# InteractiveShell instance, which is named IP. Since in testing we do need
# access to the real thing (we want to probe beyond what ipapi exposes), make
# here a global reference to each. In general, things that are exposed by the
# ipapi instance should be read from there, but we also will often need to use
# the actual IPython one.
# Get the public instance of IPython, and if it's None, make one so we can use
# it for testing

# IPython not running yet, make one from the testing machinery for
