> Objects are serialized to OutStreams and deserialized from InStreams.  Hooks
> are provided for the Perl core serialization module Storable, so that e.g.
> Storable::freeze($query) works as expected; hopefully it will prove practical
> to hook into canonical serialization routines for other hosts as well.
> The primary utility for serialization is communication between machines within
> search clusters, so all classes that may need to be sent across the network
> will eventually get serialization routines.  However, only Lucy installations
> with exactly the same version can be guaranteed to serialize and deserialize
> each others data; rolling updates are not supported.
