% struct2ini converts a given structure into an ini-file.
% It's the opposite to Andriy Nych's ini2struct. Only 
% creating an ini-file is implemented. To modify an existing
% file load it with ini2struct.m from:
%       Andriy Nych ( [e-mail] )
% change the structure and write it with struct2ini.
%

% Open file, or create new file, for writing
% discard existing contents, if any.
