uuid - DCE compatible Universally Unique Identifier library
The UUID library is used to generate unique identifiers for objects that may be
accessible beyond the local system. This library generates UUIDs compatible
with those created by the Open Software Foundation (OSF) Distributed Computing
Environment (DCE) utility uuidgen
The UUIDs generated by this library can be reasonably expected to be unique
within a system, and unique across all systems. They could be used, for
instance, to generate unique HTTP cookies across multiple web servers without
communication between the servers, and without fear of a name clash.
