Какая функция отвечает за инициализацию и проверку включенного плагина?

Question

[Влад Лисовец]

Подскажите пожалуйста, какая функция в этом коде отвечает за проверку установленного плагина и активации его работы. Этот код - дополнительный модуль к плагину начисления баллов за действия пользователей на сайте. Конкретно этот модуль - за посещение материалов пользователя другими юзерами и конвертации этих посещений в баллы. Дело в том, что меня не устраивает способ учета посетителей, который работает во вспомогательном плагине. Хочу синхронизировать другой. Пытаюсь найти мета кей, к которому этот модуль обращается в данном коде, но не могу понять.
