+ __PACKAGE__->sqlt_deploy_callback('mycallbackmethod');
+
+An accessor to set a callback to be called during deployment of
+the schema via L<DBIx::Class::Schema/create_ddl_dir> or
+L<DBIx::Class::Schema/deploy>.
+
+The callback can be set as either a code reference or the name of a
+method in the current result class.
+
+If not set, the L</default_sqlt_deploy_hook> is called.
+
+Your callback will be passed the $source object representing the
+ResultSource instance being deployed, and the
+L<SQL::Translator::Schema::Table> object being created from it. The
+callback can be used to manipulate the table object or add your own
+customised indexes. If you need to manipulate a non-table object, use
+the L<DBIx::Class::Schema/sqlt_deploy_hook>.
+
+See L<DBIx::Class::Manual::Cookbook/Adding Indexes And Functions To
+Your SQL> for examples.
+
+This sqlt deployment callback can only be used to manipulate
+SQL::Translator objects as they get turned into SQL. To execute
+post-deploy statements which SQL::Translator does not currently
+handle, override L<DBIx::Class::Schema/deploy> in your Schema class
+and call L<dbh_do|DBIx::Class::Storage::DBI/dbh_do>.

+will be called and passed the current C<$source> and the
+C<$sqlt_table> being deployed.
