% Define the command \txichapter{<format>}.  <format>
% is the format to put in the chapter head.
% 
% The command \txisection{<seclevel>}{<format>} 
% defines the <format> for the <seclevel>.
% 
% The command \txichapterdelim{<code>} sets the 
% <code> as the delimiter between chapter number and
% chapter/section name. 
% You may change the default \squad for .\space saying
% \txichapterdelim{.\space}
% 
% The rest should be self explanatory.
