=head1 Test::Smoke::Syncer::Rsync

This handles syncing with the B<rsync> program.
It should only be visible from the "parent-package" so no direct
user-calls on this.

=head2 Test::Smoke::Syncer::Rsync->new( %args )

This crates the new object. Keys for C<%args>:

  * ddir:   destination directory ( ./perl-current )
  * source: the rsync source ( ftp.linux.activestate.com::perl-current )
  * opts:   the options for rsync ( -az --delete )
  * rsync:  the full path to the rsync program ( rsync )
  * v:      verbose

=head2 $rsync->pre_sync()

Create the destination directory is it doesn't exist.

sub pre_sync {
    my $self = shift;
    if (! -d $self->{ddir}) {
        require File::Path;
        open my $fh, '>', \my $output;
        my $stdout = select $fh;
        File::Path::mkpath($self->{ddir}, $self->verbose);
        select $stdout;
        $self->log_info($output);
    }
    $self->SUPER::pre_sync;
}

=head2 $object->sync( )

Do the actual sync using a call to the B<rsync> program.

B<rsync> can also be used as a smart version of copy. If you
use a local directory to rsync from, make sure the destination path
ends with a I<path separator>! (This does not seem to work for source
paths mounted via NFS.)
