Example page
From CityDeepSky
This is just an Example page; see description of subpages in Help:Subpages.
If the subpage feature is on (default is off and this is a per namespace setting), then slashes (/) within a page name break the page into parent and subpages, recursively, eg:
Link(s) back to parent(s) of the subpage(s) automatically appear at the top of each subpage. Note that these link do not appear however if the parent page has not yet been created.
