Initial value:=
"Specify an analytic solution to impose a Dirichlet condition on the "
"lapse. The analytic solution will be evaluated at coordinates "
"centered at the apparent horizon. "
"Alternatively, set this option to 'None' "
"to impose a zero von-Neumann boundary condition on the lapse. Note "
"that the latter will not result in the standard Kerr-Schild slicing "
"for a single black hole."
