In the current version of lavaan (0.5-11), there is no function that
will compute all possible indirect/total effects automatically.
What you can do is to label the coefficients, and then use the ':='
operator to define the total/indirect effects that you are interested
in. Next, you could use se="boot" to get a bootstrap based SE.
See the lavaan paper (http://www.jstatsoft.org/v48/i02/) section 7.4 for
