# This script is tailor made for my local weather forecast, but it may work for you. 
# You should at least be able get the idea behind what it does and you can modify to 
# suit your own needs.
#
# The script uses the console web browser lynx to get my weather from the Bureau
# of Meteorology, sed to filter out the relevant lines of text amd more to display
# as output. I could probably use gmessage to display output as a pop up window but  
# this script is CLI anyway and everyone here can use/read from a console.
#
# I live on the Mornington Peninsula (AU) and my local weather forcast can be found
# at www.bom.gov.au/cgi-bin/wrap_fwo.pl?IDV17102.txt starting with a line that
# begins with "Mornington". This is the last entry on the page so I want everything 
# between "Mornington" and the first characters in the next section of that page 
# which are "[27]" or as regular expressions /Mornington/ and /\[27\]/
