# ► Module Ft.Lib.Uuid

Functions for generating and comparing Universal Unique Identifiers (UUIDs), based on ideas from e2fsprogs.
A UUID is essentially a 128-bit random number that has a string
representation of 28 hexadecimal digits, hyphenated in groups of
8-4-4-12. The value could be greater than the number of atoms in the
universe; it's extremely unlikely that the same number would ever be
generated twice.
UUIDs are defined by ISO/IEC 11578:1996 (Remote Procedure Call)
and The Open Group's DCE 1.1 (Distributed Computing Environment) spec
(the ISO version was based on an earlier version of the DCE spec).

for the current version, and also see the expired IETF Internet-Draft
http://www.opengroup.org/dce/info/draft-leach-uuids-guids-01.txt for
a version with more informative prose and examples.
