+/** DjVu Navigation Directory.
+
+    This class implements the {\em navigation directory} of a multipage
+    DjVu document - basically a list of pages that this document is composed
+    of. We would like to emphasize, that this is the list of namely
+    {\bf pages}, not {\bf files}. Any page may include any
+    number of additional files. When you've got an all-in-one-file multipage
+    DjVu document (DjVm archive) you may get the files list from \Ref{DjVmDir0}
+    class.
+
+    The \Ref{DjVuNavDir} class can decode and encode the navigation directory
+    from {\bf NDIR} IFF chunk. It's normally created by the library during
+    decoding procedure and can be accessed like any other component of
+    the \Ref{DjVuImage} being decoded.
+    
+    In a typical multipage DjVu document the navigation directory is stored
+    in a separate IFF file containing only one chunk: {\bf NDIR} chunk.
+    This file should be included (by means of the {\bf INCL} chunk) into
+    every page of the document to enable the navigation. */
