[ROOT] TMinuit with constraints

Hello Rooters,

How can I impose some constraints on parameters in TMinuit? I want to
minimize a chi square and the parameters are weight so that their sum
should be equal to 1. The "hard" way is of course to change the function
using Lagrange multipliers to get ride of the constraint but I was
wondering if TMinuit had a method to handle that the lazy way.

Thanks
