+The returned hashref will have the following structure:
+
+  { per_page => 20,   # how many entries per page
+    max      => 5,    # number of the last page
+    cur      => 2,    # number of the current page
+    common   => [     # an array of hashes for each page
+      ...,
+      { active  => 1, # set if this is the active page
+        page    => 2, # the string to display for this page
+        visible => 1, # should this be displayed in the paginating controls
+      },
+      ...
+    ]
+  }
+
+You may assume that C<cur> is sanitized to be within 1..C<max>.
+
+The common list is kept arbitrary by design, so that the algorithm to display
+the paginating controls can be changed by solely changing the
+C<make_common_pages> algorithm. If you need different glyphs for the pages or
+different boundaries, translate the C<page> entry for the page.
+
+The initial algorithm will show the following pages:
