=head1 NAME
-SQL::Translator::Producer - base object for Producers
-
-=head1 SYNOPSIS
+SQL::Translator::Producer - describes how to write a producer
=head1 DESCRIPTION
Producer modules designed to be used with SQL::Translator need to
implement a single function, called B<produce>. B<produce> will be
-called with a data structure created by a SQL::Translator::Parser
-subclass. It is expected to return a string containing a valid SQL
-create statement.
+called with the SQL::Translator object from which it is expected to
+retrieve the SQL::Translator::Schema object which has been populated
+by the parser. It is expected to return a string.
