* - 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 llok at their sizen when
* doing the layout
* - we could add the caps to the pad itself, then we should use one line per
* caps (simple caps = one line)
