%
% Users are allowed to use the friendly interface:

% \begin{quote}
%   |\documentclass[fontset = lxgw]{ctex|^^A
%   \meta{art\textup\textbar book\textup\textbar rep\textup\textbar beamer}|}|\\

% (aka \hologo{pLaTeX}-ng) supported. \hologo{pdfLaTeX} is not
% supported temporarily since the long mapping time of |zhmap|.
% Additionally, the following four commands are provided for convenience.
