+\pkg{codebox} is a \LaTeX3 package for typesetting programming source code box.
+
+Both \env{codebox} and \env{codeview} environment are provided with enironment body.
+At the same time, both \tn{codefile} and \tn{cvfile} macros are created
+for reading source code file.
+
+The starred environments(\env{codebox*} and \env{codeview*}) and
+macros(\tn{codefile*} and \tn{cvfile*}) are also provided
+to get codebox with comments at the bottom of box.

+% \StopEventually{}
+%
+% \begin{implementation}
+%
+% \section{代码实现}
+%
+% 该宏包使用 \LaTeX3 语法编写，依赖 \pkg{expl3} 环境，
+% 并需调用 \pkg{l3packages}、\pkg{tcolorbox}、\pkg{minted}
+% \pkg{listings}、\pkg{fontawesome5}等宏包。
+%
+% 按照 \LaTeX3 语法，代码中的空格、换行、回车与制表符会完全被忽略，
+% 而下划线“|_|”和冒号“|:|”则可作为一般字母使用。
+% 正常的空格可以使用“|~|”代替；至于 |~| 原来所表示的“带子”，
+% 则要用 \LaTeXe{} 的原始命令 \tn{nobreakspace} 代替。
+%
+% 以下代码中有一些形如 \textcolor[HTML]{2E3191}{\textsf{<*package>}}
+% 的标记，这是 \pkg{DocStrip} 中的“guard”，用来选择性地提取文件。
+% “\textsf{*}”和“\textsf{/}”分别表示该部分的开始和结束。不含
+% “\textsf{*}”和“\textsf{/}”的 guard 出现在行号右侧，它们用来确定
+% 单独一行代码的归属。这些 guard 的颜色深浅不一，用以明确嵌套关系。
+%
+% 另有若干形如 \textcolor[HTML]{AD1457}{\textsf{<@@=codebox>}} 的 guard，
+% 它们由 \pkg{l3docstrip} 定义，用来标识名字空间（模块）。
+%
+% \subsection{环境检测与准备}
+%
