function mwizard(file)
%MWIZARD - M2HTML Graphical User Interface
%  MWIZARD launches a Matlab GUI front-end to edit parameters
%  that are then used by M2HTML to generate HTML documentation.
%  MWIZARD(FILE) allows to specify a mat-file FILE from which
%  default parameters are extracted and can be updated.  
%
%  For more information, please read the M2HTML tutorial and FAQ at:
%    <http://www.artefact.tk/software/matlab/m2html/>
