[R] MANOVA extension of paired t-test?

What is the original manova() statement in such a case?  In other words,
one has several variables, and the desire is to test whether the mean of
each is zero (the "treatment" has been subsumed by the definition of the
variable, which is a before-after difference).  manova(Y~rep(0,nrow(Y))) is
the intuitive choice, but doesn't work.
