|ContextPages exist to hold additional configuration information for a group of pages (maybe only one page). The context pages are subpages using a configured name. The FractalWiki uses the name:
The contents of ContextPages are searched for bullet-lists of ConfigurationVariable assignments (This is for improved readability). The assigments found are executed and add to the effective configuration information that is used to render a page.
Typically the ContextPages would be writeable only by an administrator. They also might be hidden from index and excluded from search, but this shouldn't be necessary.
ContextPages are normal pages and their revisions go into the page archive automatically. So if something goes wrong, you can always go back.
