DESCRIPTION

       This  package  provides a generator of universally unique identifiers (UUID) also known as
       globally unique identifiers (GUID). This implementation follows  the  draft  specification
       from (1) although this is actually an expired draft document.

COMMANDS

       ::uuid::uuid generate
              Creates a type 4 uuid by MD5 hashing a number of bits of variant data including the
              time and hostname.  Returns the string representation of the new uuid.

       ::uuid::uuid equal id1 id2
              Compares two uuids and returns true if both arguments are the same uuid.

EXAMPLES

              % uuid::uuid generate
              b12dc22c-5c36-41d2-57da-e29d0ef5839c
