Hi *:
	I want to do a simulation where ions are moving in some medium
with a diaelectric constant of 25. I want to use PME for the
electrostatics, but I am wondering if I can turn the epsilon_r = 25 and go
ahead with PME.
	My concern is that perhaps such epislon_r is implemented only for
the cut-off scheme? (maybe I am murming nosense...).
