  24 # Collected wisdom re Perl magic incantation:
  25 #
  26 # From: Tom Hughes
  27 #
  28 # Two problems - one is that you need -p to force perl to loop over
  29 # the input lines and apply your expression to each one and then print
  30 # the results.
  31 #
  32 # The other is that as somebody else said you need to change the input
  33 # record separator so that it reads in the whole file as a single line
  34 # (which means we can do multi-line matching in a single regexp) which you
  35 # can do with the -0 switch.
  36 #
  37 # Hence -0 -p.
