+  \class NodesVisitor
+
+  \short Base class for visitors that can be used to traverse a node hierarchy.
+
+  The class follows the visitor pattern as described in Gamma et al. Pass
+  an instance of NodesVisitor to FolderNode::accept(): The visit methods
+  will be called for each node in the subtree, except for file nodes:
+  Access these through FolderNode::fileNodes() in visitProjectNode()
+  and visitoFolderNode().
