% ProcessScriptOptions() reads options and processes options as they are

% options is given as the 'index' argument of the argument array given.

% Other arguments following index may be read by special script options
% as settings (strings), images, or as operations to be processed in various
% ways. How they are treated is up to the script being processed.
%
% Note that a script not 'return' to the command line processing, nor can
% they call (and return from) other scripts. At least not at this time.
%
% There are no 'ProcessOptionFlags' control flags at this time.
