=head1 NAME
KiokuDB::TypeMap::Entry::DBIC::Schema - KiokuDB::TypeMap::Entry for DBIx::Class::Schema objects.

=head1 DESCRIPTION
This typemap entry handles references to L<DBIx::Class::Schema> as a scoped
singleton.
The ID of the schema is always C<dbic:schema>.
References to L<DBIx::Class::Schema> objects which are not a part of the
underlying L<DBIx::Class> layout are currently not supported, but may be in the
future.
