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
This library generates UUIDs compatible OSF DCE 1.1, and hash based UUIDs V3 and
V5 compatible with RFC-4122.
