=head1 NAME

DBIx::Class::Tree - Manipulate and anaylze tree structured data.  (EXPERIMENTAL)

=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. (EXPERIMENTAL)

L<DBIx::Class::Tree::AdjacencyList::Ordered> - Glue DBIx::Class::Ordered 
and DBIx::Class::Tree::AdjacencyList together. (EXPERIMENTAL)

=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.
