This library is useful for creating, comparing, parsing and printing Universally Unique Identifiers. See http://en.wikipedia.org/wiki/UUID for the general idea.
We offer two different packages: uuid and uuid-types
The uuid package aims to be a fully-featured library for working with UUIDs.
However if you're developing a library and only want the UUID type to show up
in your APIs you may want to use the uuid-types library to minimize the number
of dependencies needed by users of your library.
