This can be overidden with the value provided +by the B or B plugins. + +B<$feed_yr> is where you specify the year your site began. This is +important as atomfeed needs to create a unique, unchanging ID for +your weblog and it need this information to do so. + +Everything else is optional. + +=head1 FURTHER CONFIGURATION + +There are a lot of variables available in the plugin you can use to +customise your Atom feed. These are all listed under B, below, with some notes as to their intended usage. Some +have defaults already specified, others will silently be excluded +until you set them. + +As there are some variables generated entirely by the plugin, and as +some of the configurable variables are modified by the plugin, there +is also a complete list of all the variables available for use in +templates with notes on their form under B
