#
# The page at http://horoscopes.astrology.com/index/dailyindex.html
# contains 12 links to the 12 astrological signs.
# Each sign is associated with a URL.
# For example, Aries is associated with
# http://horoscopes.astrology.com/dailyaries.html
# and Leo is associated with
# http://horoscopes.astrology.com/dailyleo.html
#
# Looking at one of these, we find that that information
# we are interested in is found in the Web page in the
# following form:
#
# <h1>LEO</h1>
# <h3>July 23-August 22</h3><br />
# <p><span id="intelliTxt">A small event this morning blossoms
# into a full-scale epic adventure and you have the time of your
# life. If things aren't happening by mid-afternoon, you may need
# to jump-start them.
# </span>
#
# This program is given the name of sign and returns the astrological
# forecast for the day. :-)
