I recently contact Nathan about this code here : http://bazaar.launchpad.net/~lib2geom-hackers/lib2geom/trunk/view/head:/src/toys/metro.cpp

 I wanted to work with it : he suggeres me to ask on the mailing list if someone (perhaps jabertxo) could help me to turn it in a plugin...

Does anyone know about this code or could help me with this ?

Thank you in advance,

Best regards,
