Hi Robert,

I have added a new tutorial $ROOTSYS/tutorials/langaus.C
illustrating a fit with a Landau + Gaus convolution.
(see file in attachement)
The original code is from Heinz.Pernegger@cern.ch
and
Markus.Friedl@cern.ch based  on a Fortran code by R.Fruehwirth

It should not be to difficult to modify this code and replace
the TMath::Landau calls by TMath::BreitWigner.

I also received a proposal by miha.puc@marvin.fmf.uni-lj
to include a convolution of a Lorentz and Gaus function.
