1 Object::Signature is an abstract base class that you can inherit from in
2 order to allow your objects to generate unique cryptographic signatures.
4 The method used to generate the signature is based on Storable and
5 Digest::MD5. The object is fed to Storable::nfreeze to get a string,
6 which is then passed to Digest::MD5::md5_hex to get a unique 32
7 character hexadecimal signature.
