Dead easy.

void export( srcdir, targetdir ) {
  foreach ( file in srcdir.files() ) {
    if ( file.name() == "." || file.name() == ".." ) {
      return;
    }
    else if ( !isVersionControlled( file ) ) {
      return;
    }
    else if ( isDirectory( file ) ) {
      mkdir( targetdir.path() + "/" + file.name() );
      export( file, targetdir->findChild( file.name() ) );
    }
    else {
      cp( file, targetdir );
    }
  }
}

Actual implementation may slightly differ.

isVersionControlled()! I love that one.

Agreed.

I'm glad that you did it this way instead :-]
