+// CLASS DESCRIPTION (MItDependencyNodes)
+//
+// Use the dependency node iterator to traverse all the nodes in Maya's
+// Dependency Graph.
+// 
+// With filtering enabled, the iterator checks to see if the node is
+// compatible with the type specified by the filter.  See MFn::Type for a
+// list of all valid types.
+// 
+// Since MObjects may be compatible with more than one type (nodes are
+// organised in a hierarchy) the MObject::hasFn() method can be used to
+// further check for compatible types.
+// 
+// Any compatible Function Set can be attached to the retrieved object to
+// query or or edit it.  Often you will want to use the dependency node
+// function set (MFnDependencyNode), which is compatible with all
+// dependency nodes, to perform queries on each node as the iterator
+// Traverses the Dependency Graph.
