function dynare(fname, varargin)

% 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.
