-This plugin generates a list of possibly orphaned pages -- pages that no
-other page links to.
-
-The optional parameter "pages" can be a [[PageSpec]] specifying the pages
-to check for orphans, default is search them all.
-
-Note that it takes [[BackLinks]] into account, but does not count inlining a
-page as linking to it, so will generally count many blog-type pages as
-orphans.
