'''''This page is about the [Tcllib] package. For a general discussion of the concept see [GUID and UUID].''''' The `uuid` package provides a generator of universally unique identifiers (UUID) also known as globally unique identifiers (GUID). Documentation can be found at https://core.tcl.tk/tcllib/doc/trunk/embedded/www/tcllib/files/modules/uuid/uuid.html [PYK] 2016-01-29: Warning: This implementation uses `[info hostname]`, or `exec ipconfig` on [Microsoft Windows%|%Windows]. I was once offline and a program of mine was hanging. This package turned out to be the culprit. ** See Also ** [GUID and UUID]: [TclGetGUID]: [ULID]: Does not use the host information as a seed. <> Package | Tcllib
