This module converts Perl data structures to MessagePack and vice versa.
=head1 ABOUT MESSAGEPACK FORMAT
MessagePack is a binary-based efficient object serialization format.
It enables to exchange structured objects between many languages like JSON. But unlike JSON, it is very fast and small.
=head2 ADVANTAGES

=item PORTABILITY
Messagepack is language independent binary serialize format.
=item SMALL SIZE
say length(JSON::XS::encode_json({a=>1, b=>2})); # => 13
say length(Storable::nfreeze({a=>1, b=>2})); # => 21
say length(Data::MessagePack->pack({a=>1, b=>2})); # => 7
MessagePack format saves memory than JSON and Storable format.
=item STREAMING DESERIALIZER
MessagePack supports streaming deserializer. It is useful for networking such as RPC.
