SYNOPSIS

        use Linux::Bootloader;
        
        my $bootloader = new Linux::Bootloader();
        my $config_file='/boot/grub/menu.lst';
        
        $bootloader->read($config_file);
        $bootloader->print_info('all');
        $bootloader->add(%hash);
        $bootloader->update(%hash);
        $bootloader->remove(2);
        $bootloader->get_default();
        $bootloader->set_default(2);
        %hash = $bootloader->read_entry(0);
        $bootloader->write($config_file);
