Plugin API
Geeklog's Plugin API defines the interface between the core Geeklog code and the plugins. From Geeklog's point of view, all the Plugin API functions are called PLG_something, which will result in a function plugin_something_foo being called in the "foo" plugin (if it exists - all the API functions are optional).
For details about Plugin API functions that are not documented yet, please refer to the documented source code of lib-plugins.php
