# Log Server Status

# Mark J Cox, UK Web Ltd 1996, mark ukweb.com

# This script is designed to be run at a frequent interval by something

# like cron.  It connects to the server and downloads the status

# information.  It reformats the information to a single line and logs

# it to a file.  Make sure the directory $wherelog is writable by the

# user who runs this script.
