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, Microsoft COM/DCOM
for instance, uses GUIDs very extensively to uniquely identify
classes, applications and components across network-connected
systems.
