  The following is a list of the available commands.
  For more information see the detailed HELP on each command.
  If you set a parameter to 0 or do not supply it, the default is taken.
  The following are the standard MINUIT commands:

  HELP
  CALL_FCN    Calls FCN with flag `iflag'.
  MAX_CALLS   Sets the maximum number of calls for `SIMPLEX', `MIGRAD'
              and `MINOS'.
  CONTOUR     Draws a contour plot on the screen.
  COVARIANCE  Reads in the covariance matrix.
  ERROR_DEF   Sets the chi**2 or likelihood change for the errors.
  EXIT        Exits MINUIT.
  FIX         Fixes the value of a variable.
  FLOAT       Floats a previously fixed variable.
  FORCE_ISW   Changes MINUIT status flags - VERY RISKY!!
              (only in C. Rippich version).
  GRADIENT    Indicates that FCN can calculate derivatives - DO NOT USE.
  NO_GRADIENT Turns off `GRADIENT' - DO NOT USE.
  HESSE       Recalculates the covariance matrix.
  IMPROVE     Tries to find a new minimum somewhere nearby.
  INFO        Gives information on the current fit status.
  MATOUT      Writes out the covariance matrix.
  MIGRAD      Runs MIGRAD.
  MINIMIZE    Runs SIMPLEX then MIGRAD.
  MINOS       Calculates MINOS errors.
  MINUIT      Executes a MINUIT command (CERN version of MINUIT only).
  MNCONTOUR   Makes a graphical contour minimizing w.r.t. other parameters.
  MODIFY      Changes the value of a parameter, its error or limits.
  PAGE        Starts a new page on standard outupt.
  PRECISION   Sets the convergence criteria.
  PRINTOUT    Changes the printout level.
  PUNCH       Saves the current parameter values in a file.
  RELEASE     Floats a previously fixed variable (CERN version of MINUIT
              only).
  RESTORE     Floats variable(s) which were fixed.
  SAVE        Saves the current parameter values in a file
  SEEK        Monte Carlo minimization.
  SIMPLEX     Runs the fairly crude SIMPLEX minimizer.
  STANDARD    Calls subroutine STAND.
  STRATEGY    Sets the MINUIT strategy (CERN version of MINUIT only).
  STOP        Stops MINUIT.
  UNIT        Changes the output unit (do not use in Mn_Fit).

  The following commands have been defined by Mn_Fit to give you more
  information and control on what to fit and the results:

  BACK_SUB      Makes a background subtracted plot.
  CHI_PLOT      Plots the chi**2 vs. a variable even if you are doing
                a likelihood fit.
  CONSTRAIN     Constrains a parameter w.r.t. other parameters.
  UNCONSTRAIN   Removes a constraint.
  DISPLAY       Shows the fit results on the softcopy device.
  DUMP          Dumps the point by point fit values.
  EXCLUDE       Excludes part of histogram for fitting.
  NO_EXCLUDE    Removes exclusions.
  FCN_DRAW      Draws the FCN vs. a variable on the terminal.
  FCN_PLOT      Plots the chi**2 or likelihood vs. a variable.
  FIT_INFO      Gets information on the fit.
  INCLUDE       Includes part of a histogram for fitting.
  NO_INCLUDE    Removes inclusions.
  ITERATIONS    Draws fit iterations.
  NO_ITERATIONS Stops drawing fit iterations.
  PROB_PLOT     Plots the probability vs. a variable (replaces FCN_DRAW).
