If the pages to include are not specified, all pages (and other files) in
the wiki are mapped.
+By default, the names of pages are shown in the map. The `show` parameter
+can be used to show the titles or descriptions of pages instead (as set by
+the [[meta]] plugin). For example:
+
+ \[[map pages="* and !blog/* and !*/Discussion" show=title]]
+
Hint: To limit the map to displaying pages less than a certain level deep,
use a [[ikiwiki/PageSpec]] like this: `pages="* and !*/*/*"`
