 =head1 DESCRIPTION
 
 This class is designed to support the Class::DBI connection-as-classdata style
 for DBIx::Class. You are *strongly* recommended to use a DBIx::Class::Schema
 instead; DBIx::Class::DB will not undergo new development and will be moved
-to being a CDBICompat-only component before 1.0.
+to being a CDBICompat-only component before 1.0. In order to discourage further
+use, documentation has been removed as of 0.08000
