它是什么以及它做了什么？

Question

我可以猜到what<!-- INCLUDE navbar_footer.html -->，<!-- IF TRANSLATION_INFO -->，<!-- ENDIF -->和<!-- INCLUDEJS forum_fn.js -->。

但是什么是<!-- EVENT overall_footer_content_after -->，它的目的是什么？

这是文件/styles/latte/template/overall_footer.html

        <!-- EVENT overall_footer_content_after -->
    </div>

<!-- EVENT overall_footer_page_body_after -->

<div id="page-footer" class="page-footer" role="contentinfo">
    <!-- INCLUDE navbar_footer.html -->

    <div class="copyright">
        <!-- EVENT overall_footer_copyright_prepend -->
        {CREDIT_LINE}
        <!-- IF TRANSLATION_INFO --><br />{TRANSLATION_INFO}<!-- ENDIF -->
        <!-- EVENT overall_footer_copyright_append -->
        <!-- IF DEBUG_OUTPUT --><br />{DEBUG_OUTPUT}<!-- ENDIF -->
        <!-- IF U_ACP --><br /><strong><a href="{U_ACP}">{L_ACP}</a> 
</strong><!-- ENDIF -->
    </div>

    <div id="darkenwrapper" class="darkenwrapper" data-ajax-error-title="{L_AJAX_ERROR_TITLE}" data-ajax-error-text="{L_AJAX_ERROR_TEXT}" data-ajax-error-text-abort="{L_AJAX_ERROR_TEXT_ABORT}" data-ajax-error-text-timeout="{L_AJAX_ERROR_TEXT_TIMEOUT}" data-ajax-error-text-parsererror="{L_AJAX_ERROR_TEXT_PARSERERROR}">

phpBB 3.1.x引入了整个代码库和模板文件中的事件系统，允许扩展使用侦听器添加功能，注入代码和修改现有功能或行为......

事件：

 <!-- EVENT overall_footer_content_after -->

与phpBB 3.1.0-a3一起介绍，其目的是允许在页脚之前的主要内容之后的所有页面上添加内容。
