-=head1 NAME
-
-smokeping.cgi - SmokePing webfrontend
-
-=head1 OVERVIEW
-
-This script acts as a 'website' for your SmokePing monitoring operation. It
-presents the targets you are looking at in a tree structure and draws graphs
-as they are required by people looking at the pages.
-
-=head1 DESCRIPTION
-
-To get B<smokeping.cgi> going, you need a webserver which allows you to run
-cgi scripts. The system must be setup so that the B<smokeping.cgi> is
-allowed to write to the image caching area as defined in the config file.
-
-This script runs with normal perl. B<BUT> it will appear to be very slow,
-because it does a lot of things when starting up. So if the script has to be
-started a fresh on every click, this is both slow and a tough thing for your
-webserver. I therefore strongly recomment using SpeedyCGI.
-
-Please refer to the installation document for detailed setup instructions.
-
-=head1 SETUP
-
-When installing SmokePing, this file has to be adjusted to fit your
-local system. Three paths have to be entered.
-
- use lib qw(/usr/pack/rrdtool-1.0.33-to/lib/perl);
-
-One pointing to your B<rrdtool> installation
-
- use lib qw(/home/oetiker/public_html/smokeping/lib);
-
-One pointing to the place where you have installed the SmokePing libraries
-
- use Smokeping;
-
- Smokeping::cgi("/home/oetiker/.smokeping/config");
-
-The third path is the argument to the Smokeping::cgi command. It points to
-the SmokePing configuration file.
