1) In a CMSSW release:

cvs co -d MLFit UserCode/mpierini/MLFit
cd MLFit 
make -f Makefile_CMS

a shared library will be created: workdir/libMLFit.so.
This will have to be loaded in ROOT before doing fits etc.


2) setup the code to do the fit

cvs co -d RadionMLFit UserCode/crovelli/RadionMLFit

root -l RooLogon.C
.L src/FitGGData.cc 
FitGG()
PlotGG(31)
