% \section{模板介绍}
% \thubeamer\ (\textbf{T}sing\textbf{H}ua \textbf{U}niversity \LaTeX{}
% \textbf{Beamer} Template) 是为了帮助清华大学师生撰写演示文稿而编写的 \LaTeX{} Beamer 模板。
%
% 本文档将尽量完整的介绍模板的使用方法，如有不清楚之处可以参考示例文档或者根据
% 第~\ref{sec:howtoask} 节说明提问，有兴趣者可以联系作者参与完善此手册，非常欢迎你清学子对本代码作出贡献。
%
% \section{安装}
% \label{sec:installation}
%
% \thubeamer\ 已经上传 CTAN，已包含在 TeXLive 与 MiKTeX 发行版中。
% 安装方法：打开命令行，输入以下命令即可
% \begin{shell}
% $ tlmgr install thubeamer
% \end{shell}
% 阅读本说明文档可以使用以下命令：
% \begin{shell}
% $ texdoc thubeamer
% \end{shell}
%
% 如果要使用开发版，需自己下载，\thubeamer\ 相关链接：
% \begin{itemize}
% \item 主页：\href{https://github.com/YangLaTeX/thubeamer}{GitHub}
% \item 下载：\href{http://www.ctan.org/pkg/thubeamer}{CTAN}
% \end{itemize}
%
% \subsection{模板的组成}
% 下表列出了 \thubeamer{} 的主要文件及其功能介绍：

% \endlastfoot
% thubeamer.dtx & 主题宏包、说明文档以及主题驱动文件的混排文件\\
% main.tex & 主题测试文档\\
% figures/ & 主题相关矢量图存储文件夹\\
% makedoc.bat & 生成主题与用户手册脚本\\
% makebeamer.bat & 编译测试样例脚本\\
% makeclean.bat & 清理编译过程中间文件脚本\\

% \bottomrule
% \end{longtable}
% \textbf{注：}使用前，请仔细阅读\textbf{thubeamer.pdf}，即本文档。
%
% \section{使用说明}
% \label{sec:usage}
% 本手册假定用户已经能处理一般的 \LaTeX\ 文档，并对 \BibTeX\ 有一定了解。如果
% 从来没有接触过 \TeX\ 和 \LaTeX，建议先学习相关的基础知识。
%
% \subsection{关于提问}
% \label{sec:howtoask}
% 按照优先级推荐提问的位置如下：
%
% \begin{itemize}
% \item Github Issues: \href{http://github.com/YangLaTeX/thubeamer/issues}{http://github.com/YangLaTeX/thubeamer/issues}
% \item Email: \href{mailto:yanglatex2e@gmail.com}{yanglatex2e@gmail.com}, \href{mailto:yangjx20@mails.tsinghua.edu.cn}{yangjx20@mails.tsinghua.edu.cn}
% \end{itemize}
%
% \subsection{示例文件}
% \label{sec:userguide}
% 模板核心文件有四个\file{*.sty}，但是如果
% 没有示例文档用户会发现很难下手。所以推荐新用户从模板自带的示例文档入手，里面包
% 括了Beamer写作用到的所有命令及其使用方法，只需要用自己的内容进行相应替换就可以。
% 对于不清楚的命令可以查阅本手册。下面的例子描述了模板中章节的组织形式，来自于示
% 例文档，具体内容可以参考模板附带的 \file{main.tex}。
%
% \lstinputlisting[style=lstStyleLaTeX]{main.tex}
%
% \subsection{论文选项}
% \label{sec:option}
%
% 论文选项在\file{main.tex} 文件的开头描述，此处不赘述。
%
% \section{使用模板}
% \subsection{如何编译}\label{SubSec:HowToMake}
% \subsubsection{Windows用户}
% 主题项目里已经列出了脚本：
% 首先双击\file{makedoc.bat} 脚本，生成主题和用户手册；
% 然后双击\file{makebeamer.bat} 脚本生成测试 Beamer 文件预览；
% 最后双击\file{makeclean.bat} 清理编译过程的中间文件；
% 双击\file{makecleanall.bat}可以清除辅助文件以及样式文件。
%
% \subsubsection{Linux \& Mac OS用户}
% 首先运行下面命令生成主题和用户手册；
% \begin{shell}
% $ make doc
% \end{shell}
%
% 然后运行下面命令生成测试 Beamer 文件预览；
% \begin{shell}
% $ make beamer
% \end{shell}
%
% 最后运行下面命令清理编译过程的中间文件。
% \begin{shell}
% $ make clean
% \end{shell}
%
% 若运行下面命令则清理编译过程的中间文件以及所有样式文件。
% \begin{shell}
% $ make cleanall
% \end{shell}
%
% \section{致谢}
% \label{sec:thanks}
% 感谢 \href{https://github.com/StickCui/XDUstyle-Beamer-Theme}{XDUstyle}、\href{https://github.com/tl3shi/THUBeamer}{thubeamer} 模板的作者，本模板基于他们改编而来！
