  {temp} values = Tstart Tstop Tdamp

    Tstart,Tstop = external temperature at start/end of run

    Tdamp = temperature damping parameter (time units)

    alpha = strength of Cauchystat control parameter

    continue = {yes} or {no} = whether of not to continue from a previous run

  {fixedpoint} values = x y z

    x,y,z = perform barostat dilation/contraction around this point (distance units)

    x,y,z = perform barostat dilation/contraction around this point (distance units) :pre
