With this extension different pages can include or exclude selected sections from a source page. Excellent for logical organization of info in the same category but different contexts/components. For example, import settings of 20 sub-plugins can reside in one page and provide one view of all settings, and each sub-plugin specific section is transcluded into the respective sub-plugin page (template syntax). Maintenance of the documentation of these import settings becomes much easier because it is done in one place and populated by transclusion to all other pages.
