if you read this with netscape,
then it (would you believe) shows reverse ' as '

e.g.
in netscape these will be the same  ` '
but I typed them differntly.. (duh)

since I am using netscape to type this
I don't even know if they actually got entered
as different characters because they echo on the screen as the same.!
