+=head1 NAME
+
+DBIx::Class::UUIDColumns - Implicit uuid columns
+
+=head1 SYNOPSIS
+
+ package Artist;
+ __PACKAGE__->load_components(qw/UUIDColumns Core DB/);
+ __PACKAGE__->uuid_columns( 'artist_id' );
+
+=head1 DESCRIPTION
+
+This L<DBIx::Class> component resembles the behaviour of
+L<Class::DBI::UUID>, to make some columns implicitly created as uuid.
+
+When loaded, C<UUIDColumns> will search for a suitable uuid generation module
+from the following list of supported modules:
+
+ Data::UUID
+ APR::UUID*
+ UUID
+ Win32::Guidgen
+ Win32API::GUID
+
+If no supporting module can be found, an exception will be thrown.
+
+*APR::UUID will not be loaded under OpenBSD due to an as yet unidentified XS
+issue.
+
+If you would like to use a specific module, you can set C<uuid_class>:
+
+ __PACKAGE__->uuid_class('::Data::UUID');
+ __PACKAGE__->uuid_class('MyUUIDGenerator');
+
+Note that the component needs to be loaded before Core.
+
+=head1 METHODS
+
+=head2 uuid_columns(@columns)
+
+Takes a list of columns to be filled with uuids during insert.
+
+ __PACKAGE__->uuid_columns('id');
+
+=head2 uuid_class($classname)
+
+Takes the name of a UUIDMaker subclass to be used for uuid value generation.
+This can be a fully qualified class name, or a shortcut name starting with ::
+that matches one of the available DBIx::Class::UUIDMaker subclasses:
+
+ __PACKAGE__->uuid_class('CustomUUIDGenerator');
+ # loads CustomeUUIDGenerator
+
+ __PACKAGE->uuid_class('::Data::UUID');
+ # loads DBIx::Class::UUIDMaker::Data::UUID;
+
+Note that C<uuid_class> chacks to see that the specified class isa
+DBIx::Class::UUIDMaker subbclass and throws and exception if it isn't.
+
+=head2 uuid_maker
+
+Returns the current UUIDMaker instance for the given module.
+
+ my $uuid = __PACKAGE__->uuid_maker->as_string;
