-=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.
