+=head1 DESCRIPTION
+
+The tree modules provide the tools to represent, modify, and analyze
+trees of data with DBIx::Class.
+
+=head1 COMPONENTS
+
+L<DBIx::Class::Tree::AdjacencyList> - Manage a tree of data using the
+common adjacency list model.
+
+L<DBIx::Class::Tree::AdjacencyList::Ordered> - Glue DBIx::Class::Ordered
+and DBIx::Class::Tree::AdjacencyList together.
+
+=head1 DAG
+
+All tree related modules must conform to have and use the basic traversal
+methods of a DAG.  For the most part this just means that Tree modules
+must provide the appearance of having multiple parents per node (via a
+parents() method) but may very well never return more than one parent.
+All utility modules, such as a Visitor module, should do its best to
+never assume that a node only has one parent.  There are situations
+where this is not possible - in those cases the module's documentation
+should clearly state that it is not compatible with DAGs.
+
+So far there is no Tree::DAG module, but there will be.  These requirements
+are vague, and the requirements of Tree modules to be DAG compatible will
+become more defined in due course.
