I am running an IRC bot to capture CNN news
When I call any news, it gave me the following
<ryeywe> !news list
<sdc> CNN Top Stories Headlines (c) CNN.com - by Thrill "!news help"
for options
<sdc>  Get RSS direct from CNN.com! (http://www.cnn.com/services/rss/index.=
html)


I am using the following news.tcl

# CNN news.tcl V1.1
# by Thrill
#
# All newsheadlines parsed by this script are (C) cnn.com
#
# Version History: V1.0  - first public release
#                  V1.01 - stupid bug ('putchan') fixed
#                  V1.1  - added URL's to the newsitem.
# Remember to change this script before implementing it!
Remove/comment the 'die "CNN News not changed!"' afterwards.
# Only the location of lynx needs change.
#
# The author takes no responsibility whatsoever for the usage and
working of this script !
#
# E-mail: jmildham59@hotmail.com

# default bind command !news, change to your liking
bind pub - "!news" news

# set the location of lynx here. Normally this should be ok.
#set lynx "/usr/bin/lynx"
set lynx "/usr/local/bin/lynx"

#set locations of tempfiles here, default /tmp/newstmp1.txt,
newstmp2.txt should be ok
set ftemp1 "/tmp/newstmp1.txt"
set ftemp2 "/tmp/newstmp2.txt"

# comment or remove this when you are done
# die "CNN News not changed!"
# see function PARSE below for the output-string, which can be changed
if you like, example included.

#### DO NOT EDIT BELOW - EVERY CHANGE IS ON YOUR OWN RISK AND COULD
LEAD THIS SCRIPT TO FAIL! ####
