+=head1 NAME
+
+SQL::Translator::Producer::YAML - A YAML producer for SQL::Translator
+
+=head1 SYNOPSIS
+
+  use SQL::Translator;
+
+  my $translator = SQL::Translator->new(producer => 'YAML');
+
+=head1 DESCRIPTION
+
+This module uses YAML to serialize a schema to a string so that it
+can be saved to disk.  Serializing a schema and then calling producers
+on the stored can realize significant performance gains when parsing
+takes a long time.
