I'd prefer to avoid adding this new program. xeno-test is already more
complicated than I would like, and I am almost sure that we can handle
differences between the shells by testing what shell we are running (for
instance using the SHELL variable) and using some explicit "ifs" in the
script.

I get a 404.
