Only links between mapped pages will be shown; links pointing to or from
unmapped pages will be omitted. If the pages to include are not specified,
-the links between all pages (and other files) in the wiki are mapped. For
-best results, only a small set of pages should be mapped, since otherwise
-the map can become very large, unweildy, and complicated. Also, the map is
-rebuilt whenever one of the mapped pages is changed, which can make the
-wiki a bit slow.
+the links between all pages (and other files) in the wiki are mapped.
Here are descriptions of all the supported parameters to the `linkmap`
directive:
* `height`, `width` - Limit the size of the map to a given height and width,
in inches. Both must be specified for the limiting to take effect, otherwise
the map's size is not limited.
+* `connected` - Controls whether to include pages on the map that link to
+ no other pages (connected=no, the default), or to only show pages that
+ link to others (connected=yes).

+For best results, only a small set of pages should be mapped, since
+otherwise the map can become very large, unwieldy, and complicated.
+If too many pages are included, the map may get so large that graphviz
+cannot render it. Using the `connected` parameter is a good way to prune
+out pages that clutter the map.
