For those that don't know, the s/// thing is basically saying replace the first bit with the second bit.
s/Imperial Senate/Security Council/;
s/this battle station/the pentagon/;
s/regional governors/the generals/;
s/Old Republic/United Nations/;
s/local systems/regional competitors/;
to be used with this text:
TARKIN: The Imperial Senate will no longer be of any concern to us. I've just received word that the Emperor has dissolved the council permanently. The last remnants of the Old Republic have been swept away.
TAGGE: That's impossible! How will the Emperor maintain control without the bureaucracy?
TARKIN: The regional governors now have direct control over territories. Fear will keep the local systems in line. Fear of this battle station.
