Template:Lecture alt

About
This template is used for categorising lectures.

The template contains some code which does the following:
 * If the page is not a subpage, the page is categorised as a lecture.
 * If the page is a subpage, the page is categorised as a lecture.
 * If the rootname category does not yet exist, the user is warned to create the rootname category and add the rootname category to the category "lectures"; the page is then also added to a list of lectures where the rootname category is missing.
