MPFit: changing the cost function [message #58595]

Hello,

I am using Craig Markwardt's MPFit with great enjoyement but I would
like to change the way the model error is calculated. MPfit minimizes
the Chi^2 but for what I want to do, I would prefer minimizing "the
largest relative error" rather than the "mean relative error".
I haven't found any hint in the documentation about "user-defined cost
function". Shall I modify MPfit itself to add this option or did I
miss something?
Thanks,
Thomas
