Java UUID Generator (JUG) is a Java library for generating
Universally Unique IDentifiers, UUIDs (see http://en.wikipedia.org/wiki/UUID).
It can be used either as a component in a bigger application, or as a standalone command line tool.
JUG generates UUIDs according to the IETF UUID draft specification.
JUG supports 3 original official UUID generation methods as well as later additions (v6, v7)
