Webrings and Links
# This script now works with IIS (Internet Infromation Server)
# and PWS (Personal Web Server)!
#
# This script requires that PERL is loaded on your web server
# and that the web server is configured to run PERL scripts as
# CGI scripts.
#
# Configure the script in the User Configuration section below.
#
# Upload this file to your CGI directory on your web server in
# ASCII mode. If you do not know if you have a CGI directory,
# ask your web server administrator.
#
# Chmod this file to 755, if you have Unix.
#
# On unix machines you must create an empty file with the name
# of your log file and then chmod it to 777. Most NT machines
# do this automatically for you.
#
# On unix machines you must create the map data file with the cordinates
# Upload it in Asci and then chmod it to 744.
#
# The script is called by creating a link like this
#
# 
#
#
# An exmaple of the data file is
# url|x1|y1|x2|y2
#
# for the url to go to, do not include http://
#
# 0,0 is in the upper left corner of the image
# so in other terms this is your rectangle
# x1,y1.........................x2,y1
# . .
# . .
# x1,y2.........................x2,y2
