# This program gets the slashdot.xml from slashdot.org
# and extracts the and <url> elements from each
# of the <story> elements stored in the dot-xml file.
# It dynamically generates a webpage that displays the
# titles as hyperlinks to Slashdot articles.
#
# The dynamically generated dot-html file is installed
# in the MOTD directory.
#
# The following cron entry is used to generate the
# webpage once an hour.
