+=head1 NAME
+
+DBIx::Class::Storage::ODBC::ACCESS - Support specific to MS Access over ODBC
+
+=head1 WARNING
+
+I am not a DBI, DBIx::Class or MS Access guru. Use this module with that in
+mind.
+
+This module is currently considered alpha software and can change without notice.
+
+=head1 DESCRIPTION
+
+This class implements support specific to Microsoft Access over ODBC. It currently only
+implements functions necessary for working with auto-incremented primary keys.
+
+It is loaded automatically by by DBIx::Class::Storage::DBI::ODBC when it
+detects a MS Access back-end.
+
+=head1 SUPPORTED VERSIONS
+
+This module have currently only been tested on MS Access 2003 using the Jet 4.0 engine.
+
+As far as my knowledge it should work on MS Access 2000 or later, but that have not been tested.
+Information about support for different version of MS Access is welcome.
+
+=head1 IMPLEMENTATION NOTES
+
+MS Access supports the @@IDENTITY function for retriving the id of the latest inserted row.
+@@IDENTITY is global to the connection, so to support the possibility of getting the last inserted
+id for different tables, the insert() function stores the inserted id on a per table basis.
+last_insert_id() then just returns the stored value.
+

+=head1 BUGS
+
+Most likely. Bug reports are welcome.
