+MooseX::Types::UUID - UUID type for Moose classes
+
+=head1 SYNOPSIS
+
+  package Class;
+  use Moose;
+  use MooseX::Types::UUID qw(UUID);
+  
+  has 'uuid' => ( is => 'ro', isa => UUID );
+
+  package main;
+  Class->new( uuid => '77C71F92-0EC7-11DD-B986-DF138EE79F6F' );
+
+=head1 DESCRIPTION
+
+This module lets you constrain attributes to only contain UUIDs (in
+their usual human-readable form).  No coercion is attempted.
+
+=head1 EXPORT
+
+None by default, you'll usually want to request C<UUID> explicitly.
