[ROOT] New data member & trees

Hello,

we added some data members in a class, but now we are not able to read the
old root trees. The only hint I found in the digests is to add some lines
in the streamer function like:
if (R__v > 1) { R__b >> newdata;}

But I think the streamer function is created automatically, so I have to
add it after the creation of EventDict.cpp, each? Or is it possible to do
this version management also automatically?

Thanks for your help, Ingo
