=head2 header_wanted

Saves the header of the structure into C<< $proc->header >>. You can
reach it via C<< $flow->procs->[ $i ]->header >>, where C<$i> is the
index of the DBF processor in your flow. For example:

  my $flow = DataFlow->new([
      [ 'DBF' => { direction => 'CONVERT_FROM', header_wanted => 1 } ],
  ]);

  my $perl_data = $flow->process( $dbf_data );
  my $header    = $flow->procs->[0]->header;

=head2 dbf_opts

  my $flow = DataFlow->new([
     [ 'DBF' => {
         direction => 'CONVERT_FROM',
         dbf_opts  => { name => 'dbase.dbf' },
       }
     ],
  ]);

Sets any particular option you may want to pass to L<XBase>. The most
important one being B<name>, in which you can specify a file name
for either input (CONVERT_FROM) or output (CONVERT_TO).
