=head1 NAME

SQL::Translator::Producer::Storable - serializes the SQL::Translator::Schema 
    object via the Storable module

=head1 SYNOPSIS

  use SQL::Translator;

  my $translator = SQL::Translator->new;
  $translator->producer('Storable');

=head1 DESCRIPTION

This module uses Storable 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.
