Provide scripts to set up transparent proxying, where supported

Setting up a transparent TOR proxy is quite complicated when it comes to firewall rules (e.g. IPTables). Any configuration slip breaks the anonymity.

So I suggest to add the options 'Trans{Local|MiddleBox}IPv{4|6}' to torrc which automagically configure a transparent TOR proxy with all necessary settings (e.g. IPTables rules, system resolver set-up with .onion).
