Universally unique ID library
http://en.wikipedia.org/wiki/Util-linux
This is the universally unique ID development library and headers,
part of util-linux.
The libuuid library generates and parses 128-bit universally unique
id's (UUID's). A UUID is an identifier that is unique across both
space and time, with respect to the space of all UUIDs. A UUID can
be used for multiple purposes, from tagging objects with an extremely
short lifetime, to reliably identifying very persistent objects
across a network.
See also the "uuid-devel" package, which is a separate implementation.
