=head1 NAME 

    DBIx::Class::Serialize::Storable - hooks for Storable freeze/thaw
    (EXPERIMENTAL)

=head1 SYNOPSIS

    # in a table class definition
    __PACKAGE__->load_components(qw/Serialize::Storable/);
    
    # meanwhile, in a nearby piece of code
    my $cd = $schema->resultset('CD')->find(12);
    $cache->set($cd->ID, $cd); # if the cache uses Storable, this
			       # will work automatically

=head1 DESCRIPTION

This component adds hooks for Storable so that row objects can be
serialized. It assumes that your row object class (C<result_class>) is
the same as your table class, which is the normal situation. However,
this code is not yet well tested, and so should be considered
experimental.
