1 Root

  Mn_Fit can fetch ROOT histograms so that its fitting (and plotting) features
  can also be used in conjunction with ROOT. The interface is very new and so
  probably has a number of bugs and I am sure that several necessary checks
  for errors are not yet made. Please also look out for memory leaks.

  I only plan to support the reading in of histograms (1-D, 2-D and 3-D) as
  well as profile plots (3-D histogram support will be added soon). I do not
  plan to make it possible to read in Ntuples - this is too much work. Create
  your histograms from Ntuples within ROOT and then read them in with Mn_Fit.

  It seems as if the Mn_Fit executable including root is not really
  transportable, so you should compile Mn_Fit yourself if you want to use
  this feature. The environment varibale `ROOTSYS' must be set before you run
  the Makefile. The Mn_fit startup script will set `ROOTSYS' to whatever it was
  when the executable was made.

  In order to use the ROOT interface Mn_Fit must have been compiled with the
  ROOT option turned on. Use the command `make all_root' to make both nomral
  and ROOT interface excutables. The environment variable `ROOTSYS' must
  also be set before starting Mn_Fit.
