Description:

This module provides a framework for generating UUIDs (Universally
Unique Identifiers, also known as GUIDs (Globally Unique Identifiers).
A UUID is 128 bits long, and is guaranteed to be different from all
other UUIDs/GUIDs generated until 3400 A.D. UUIDs were originally used
in the Network Computing System (NCS) and later in the Open Software
Foundation's (OSF) Distributed Computing Environment. Currently many
different technologies rely on UUIDs to provide unique identity for
various software components.
