GroupHeaders and GroupFooters

Every WikiGroup can have `GroupHeader and `GroupFooter pages that contain markup that should be included at the beginning or end of each page within the group. This feature is useful for:

• adding a disclaimer or heading to all of the pages of a group
• defining custom WikiStyles that may be used for all pages in a group
• replacing the default headers and/or footers for pages in a group (e.g., using (:noheader:) and or (:nofooter:) -- see PageDirectives).

To create a group header, just create a new page called YourGroup.GroupHeader. Group headers allow authors to create groups with custom headers and footers without having to coordinate with a wiki administrator.

The default `GroupHeader or `GroupFooter can be suppressed on an individual page (such as a group's `HomePage) by using the (:nogroupheader:) and (:nogroupfooter:) markups on that page.

If a generic `GroupHeader is used in one wikigroup (say, the Site wikigroup), then the code can be easily duplicated in the `GroupHeader of any other group by using (:include Site.GroupHeader:). See IncludeOtherPages.

If you want a header or footer to appear when you print a page (action print), simply create a page called YourGroup.GroupPrintHeader or YourGroup.GroupPrintFooter and fill it with your markup.

You can also set the variable $GroupPrintHeaderFmt and $GroupPrintFooterFmt in the same way as $GroupHeaderFmt and GroupFooterFmt in order to change the header used when action=print.

$GroupHeaderFmt = '(:include {$SiteGroup}.SiteHeader'

$GroupFooterFmt .= '(:nl:)(:include {$SiteGroup}.SiteFooter'
  . ' basepage={*$FullName}:)';
