| * |
| * for more compact nodes, try |
| * - changing node-shape from box into record |
| * - use labels like : element [ label="{element | <src> src | <sink> sink}"] |
| * - point to record-connectors : element1:src -> element2:sink |
| * - we use head/tail labels for pad-caps right now |
| * - this does not work well, as dot seems to not look at their size when |
| * doing the layout |
| * - we could add the caps to the pad itself, then we should use one line per |
