function dynare(fname, varargin)
%       This command runs dynare with specified model file in argument
%       Filename.
%       The name of model file begins with an alphabetic character, 
%       and has a filename extension of .mod or .dyn.
%       When extension is omitted, a model file with .mod extension
%       is processed.
%
% INPUTS
%   fname:      file name
%   varargin:   list of arguments following fname
