[ROOT] MakeClass and friends

Hi,

I have several different trees that I want to analyze at once.  Rather 
than add the branches together and rewrite the tree, I have done the 
AddFriend thing and can for instance tree->Draw("var from tree 1":"var 
from tree 2"...just like in the manual.

But I want to use MakeClass to a real analysis.  Unfortunately, 
tree->MakeClass("mycode") only produces a .h file with the stuff from 
the original tree in it, and nothing from any of the friends.

To be specific, I'm doing something like:

TFile *f=new TFile("ALTR.root");
TTree *t1 = (TTree*) f->Get("theStuff");
t1.AddFriend("t2 = theStuff","BEAS.root");
t1.AddFriend("t3 = theStuff","BRCD.root");
t1->MakeClass("mycode")

What can I do to get a .h with all friend's variables included?

	- John
