[ROOT] comparing two histograms

Dear ROOTers,

	I am trying to compare two very similar histograms...so similar that 
KolmogorovTest returns exactly one for the comparision.  OK, that's nice, but 
these histograms have error bars on them, and I'd like to quantify the how 
different they are based on the errors.  Does ROOT have a function that 
computes a chisquared between two histograms?  Or a function that allows one 
to fit one histogram with another histogram as the "user function"?  Thanks, 
best wishes.

						Ken
