instance, for a module that could optionally use either MySQL or
PostgreSQL databases, you might use C<auto_features> like this:

  my $build = Module::Build->new
    (
     ...other stuff here...
     auto_features => {
       pg_support    => {
                         description => "Interface with Postgres databases",
                         requires    => { 'DBD::Pg' => 23.3,
                                          'DateTime::Format::Pg' => 0 },
                        },
       mysql_support => {
                         description => "Interface with MySQL databases",
                         requires    => { 'DBD::mysql' => 17.9,
                                          'DateTime::Format::MySQL' => 0 },
                        },
     }
    );

For each feature named, the required prerequisites will be checked, and
if there are no failures, the feature will be enabled (set to C<1>).
Otherwise the failures will be displayed to the user and the feature
will be disabled (set to C<0>).
