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