-	  - This is a re-write of GraphViz. The method parameter lists are incompatible.
-	  	Sorry, but it now supports all options and attributes in Graphviz V 2.23.6.
-	  - Rewrite GraphViz, GraphViz::Data::Grapher, GraphViz::Parse::RecDescent, GraphViz::Parse::Yacc and GraphViz::Parse::Yapp.
-	  	The core code of *::RecDescent, *::Yacc and *::Yapp has been copied from GraphViz, with tiny changes.
-	  - GraphViz2::Data::Grapher uses Tree::DAG_Node to hold information, before calling external plotting programs.
-	  	The tree is available for you to process whether or not you actually plot the graph.
-	  - GraphViz::Regex renamed GraphViz2::Parse::Regexp.
-	  - GraphViz::XML renamed GraphViz2::Parse::XML. And it uses XML::Tiny by default.
-	  	One demo shows how to use XML::Bare instead.
-	  - All new documentation.
-	  - All new demos, in scripts/*.pl. These are documented in GraphViz's POD.

+=head2 Why did I get an error about 'Unable to find primary key'?
+
+For plotting foreign keys, the code has an algorithm to find the primary table/key pair which the
+foreign table/key pair point to.
+
+The steps are listed here, in the order they are tested. The first match stops the search.

+Currently, the only special case is a foreign key of C<spouse_id>. It is assumed to point to a

+There is no option available, at the moment, to override this check.
+
+=item o Ask the database for foreign key information
+
+L<DBIx::Admin::TableInfo> is used for this.
