The template could be any HTML that includes [[plugin]]. First, the Plug-in replaces [[plugin]] with the generated contents. The contents imply, for example, TagCloud or PageList in a website. Next, the Plug-in replaces all the contents in the sprite with the template.
Some Plug-ins ignore the Plug-in template. Take care to check whether the template is available or not.
PositLog can create the content of the sprite dynamically by using Plug-ins. For example, a sprite shows the up-to-date contents by importing the entries or RSS feeds of a blog. Besides, many useful Plug-ins for arranging contents are provided, such as TagCloud, PageList, and RecentContents.
This page explains the general information for configuring and using Plug-ins.
