Allowed values:(integer)
Default value:0



If non-zero, Special:Export can be used to export all pages linked to or from the specified page, or from those pages, or from those pages, and so forth, up to a maximum depth governed by this parameter. Since this can include an really really large number of pages and could easily break a wiki, the default (0) disables the feature.
