-*Usage
- #navi(page)

--page~

+/*
+ * Usage:
+ * #navi(contents-page-name) <for ALL child pages>
+ * #navi([contents-page-name]) <for contents page>
+ *
+ * Parameter:
+ * contents-page-name - Page name of home of the navigation (default:itself)
+ *
+ * Behaviour at contents page:
+ * Always show child-page list like 'ls' plugin
+ *
+ * Behaviour at child pages:
+ *
+ * The first plugin call - Show a navigation bar like a DocBook header
+ *
+ * Prev <contents-page-name> Next
+ * --------------------------------
+ *
+ * The second call - Show a navigation bar like a DocBook footer
+ *
+ * --------------------------------
+ * Prev Home Next
+ * <pagename> Up <pagename>
+ *
+ * Page-construction example:
+ * foobar - Contents page, includes '#navi' or '#navi(foobar)'
+ * foobar/1 - One of child pages, includes one or two '#navi(foobar)'
+ * foobar/2 - One of child pages, includes one or two '#navi(foobar)'
