+
+LPPL Version 1.3c  2008-05-04
+
+Copyright 1999 2002-2008 LaTeX3 Project
+    Everyone is allowed to distribute verbatim copies of this
+    license document, but modification of it is not allowed.
+
+
+PREAMBLE
+========
+
+The LaTeX Project Public License (LPPL) is the primary license under
+which the LaTeX kernel and the base LaTeX packages are distributed.
+
+You may use this license for any work of which you hold the copyright
+and which you wish to distribute.  This license may be particularly
+suitable if your work is TeX-related (such as a LaTeX package), but 
+it is written in such a way that you can use it even if your work is 
+unrelated to TeX.
+
+The section `WHETHER AND HOW TO DISTRIBUTE WORKS UNDER THIS LICENSE',
+below, gives instructions, examples, and recommendations for authors
+who are considering distributing their works under this license.
+
+This license gives conditions under which a work may be distributed
+and modified, as well as conditions under which modified versions of
+that work may be distributed.
+
+We, the LaTeX3 Project, believe that the conditions below give you
+the freedom to make and distribute modified versions of your work
+that conform with whatever technical specifications you wish while
+maintaining the availability, integrity, and reliability of
+that work.  If you do not see how to achieve your goal while
+meeting these conditions, then read the document `cfgguide.tex'
+and `modguide.tex' in the base LaTeX distribution for suggestions.
+
+
+DEFINITIONS
+===========
+
+In this license document the following terms are used:
+
+   `Work'
+    Any work being distributed under this License.
+    
+   `Derived Work'
+    Any work that under any applicable law is derived from the Work.
+
+   `Modification' 
+    Any procedure that produces a Derived Work under any applicable
+    law -- for example, the production of a file containing an
+    original file associated with the Work or a significant portion of
+    such a file, either verbatim or with modifications and/or
+    translated into another language.
+
+   `Modify'
+    To apply any procedure that produces a Derived Work under any
+    applicable law.
+    
+   `Distribution'
+    Making copies of the Work available from one person to another, in
+    whole or in part.  Distribution includes (but is not limited to)
+    making any electronic components of the Work accessible by
+    file transfer protocols such as FTP or HTTP or by shared file
+    systems such as Sun's Network File System (NFS).
+
+   `Compiled Work'
+    A version of the Work that has been processed into a form where it
+    is directly usable on a computer system.  This processing may
+    include using installation facilities provided by the Work,
+    transformations of the Work, copying of components of the Work, or
+    other activities.  Note that modification of any installation
+    facilities provided by the Work constitutes modification of the Work.
+
+   `Current Maintainer'
+    A person or persons nominated as such within the Work.  If there is
+    no such explicit nomination then it is the `Copyright Holder' under
+    any applicable law.
+
+   `Base Interpreter' 
+    A program or process that is normally needed for running or
+    interpreting a part or the whole of the Work.    
+
+    A Base Interpreter may depend on external components but these
+    are not considered part of the Base Interpreter provided that each
+    external component clearly identifies itself whenever it is used
+    interactively.  Unless explicitly specified when applying the
+    license to the Work, the only applicable Base Interpreter is a
+    `LaTeX-Format' or in the case of files belonging to the 
+    `LaTeX-format' a program implementing the `TeX language'.
+
+
+
+CONDITIONS ON DISTRIBUTION AND MODIFICATION
+===========================================
+
+1.  Activities other than distribution and/or modification of the Work
+are not covered by this license; they are outside its scope.  In
+particular, the act of running the Work is not restricted and no
+requirements are made concerning any offers of support for the Work.
+
+2.  You may distribute a complete, unmodified copy of the Work as you
+received it.  Distribution of only part of the Work is considered
+modification of the Work, and no right to distribute such a Derived
+Work may be assumed under the terms of this clause.
+
+3.  You may distribute a Compiled Work that has been generated from a
+complete, unmodified copy of the Work as distributed under Clause 2
+above, as long as that Compiled Work is distributed in such a way that
+the recipients may install the Compiled Work on their system exactly
+as it would have been installed if they generated a Compiled Work
+directly from the Work.
+
+4.  If you are the Current Maintainer of the Work, you may, without
+restriction, modify the Work, thus creating a Derived Work.  You may
+also distribute the Derived Work without restriction, including
+Compiled Works generated from the Derived Work.  Derived Works
+distributed in this manner by the Current Maintainer are considered to
+be updated versions of the Work.
+
+5.  If you are not the Current Maintainer of the Work, you may modify
+your copy of the Work, thus creating a Derived Work based on the Work,
+and compile this Derived Work, thus creating a Compiled Work based on
+the Derived Work.
+
+6.  If you are not the Current Maintainer of the Work, you may
+distribute a Derived Work provided the following conditions are met
+for every component of the Work unless that component clearly states
+in the copyright notice that it is exempt from that condition.  Only
+the Current Maintainer is allowed to add such statements of exemption 
+to a component of the Work. 
+
+  a. If a component of this Derived Work can be a direct replacement
+     for a component of the Work when that component is used with the
+     Base Interpreter, then, wherever this component of the Work
+     identifies itself to the user when used interactively with that
+     Base Interpreter, the replacement component of this Derived Work
+     clearly and unambiguously identifies itself as a modified version
+     of this component to the user when used interactively with that
+     Base Interpreter.
+     
+  b. Every component of the Derived Work contains prominent notices
+     detailing the nature of the changes to that component, or a
+     prominent reference to another file that is distributed as part
+     of the Derived Work and that contains a complete and accurate log
+     of the changes.
+  
+  c. No information in the Derived Work implies that any persons,
+     including (but not limited to) the authors of the original version
+     of the Work, provide any support, including (but not limited to)
+     the reporting and handling of errors, to recipients of the
+     Derived Work unless those persons have stated explicitly that
+     they do provide such support for the Derived Work.
+
+  d. You distribute at least one of the following with the Derived Work:
+
+       1. A complete, unmodified copy of the Work; 
+          if your distribution of a modified component is made by
+          offering access to copy the modified component from a
+          designated place, then offering equivalent access to copy
+          the Work from the same or some similar place meets this
+          condition, even though third parties are not compelled to
+          copy the Work along with the modified component;
+
+       2. Information that is sufficient to obtain a complete,
+          unmodified copy of the Work.
+
+7.  If you are not the Current Maintainer of the Work, you may
+distribute a Compiled Work generated from a Derived Work, as long as
+the Derived Work is distributed to all recipients of the Compiled
+Work, and as long as the conditions of Clause 6, above, are met with
+regard to the Derived Work.
+
+8.  The conditions above are not intended to prohibit, and hence do not
+apply to, the modification, by any method, of any component so that it
+becomes identical to an updated version of that component of the Work as
+it is distributed by the Current Maintainer under Clause 4, above.
+
+9.  Distribution of the Work or any Derived Work in an alternative
+format, where the Work or that Derived Work (in whole or in part) is
+then produced by applying some process to that format, does not relax or
+nullify any sections of this license as they pertain to the results of
+applying that process.
+     
+10. a. A Derived Work may be distributed under a different license
+       provided that license itself honors the conditions listed in
+       Clause 6 above, in regard to the Work, though it does not have
+       to honor the rest of the conditions in this license.
+      
+    b. If a Derived Work is distributed under a different license, that
+       Derived Work must provide sufficient documentation as part of
+       itself to allow each recipient of that Derived Work to honor the 
+       restrictions in Clause 6 above, concerning changes from the Work.
+
+11. This license places no restrictions on works that are unrelated to
+the Work, nor does this license place any restrictions on aggregating
+such works with the Work by any means.
+
+12.  Nothing in this license is intended to, or may be used to, prevent
+complete compliance by all parties with all applicable laws.
+
+
+NO WARRANTY
+===========
+
+There is no warranty for the Work.  Except when otherwise stated in
+writing, the Copyright Holder provides the Work `as is', without

+
+In no event unless required by applicable law or agreed to in writing

+anyone as a result of any failure of the Work to operate with any other
+programs), even if the Copyright Holder or said author or said other
+party has been advised of the possibility of such damages.
+
+
+MAINTENANCE OF THE WORK
+=======================
+
+The Work has the status `author-maintained' if the Copyright Holder
+explicitly and prominently states near the primary copyright notice in
+the Work that the Work can only be maintained by the Copyright Holder
+or simply that it is `author-maintained'.
+
+The Work has the status `maintained' if there is a Current Maintainer
+who has indicated in the Work that they are willing to receive error
+reports for the Work (for example, by supplying a valid e-mail
+address). It is not required for the Current Maintainer to acknowledge
+or act upon these error reports.
+
+The Work changes from status `maintained' to `unmaintained' if there
+is no Current Maintainer, or the person stated to be Current
+Maintainer of the work cannot be reached through the indicated means
+of communication for a period of six months, and there are no other
+significant signs of active maintenance.
+
+You can become the Current Maintainer of the Work by agreement with
+any existing Current Maintainer to take over this role.
+
+If the Work is unmaintained, you can become the Current Maintainer of
+the Work through the following steps:
+
+ 1.  Make a reasonable attempt to trace the Current Maintainer (and
+     the Copyright Holder, if the two differ) through the means of
+     an Internet or similar search.
+
+ 2.  If this search is successful, then enquire whether the Work
+     is still maintained.
+
+  a. If it is being maintained, then ask the Current Maintainer
+     to update their communication data within one month.
+     
+  b. If the search is unsuccessful or no action to resume active
+     maintenance is taken by the Current Maintainer, then announce
+     within the pertinent community your intention to take over
+     maintenance.  (If the Work is a LaTeX work, this could be
+     done, for example, by posting to comp.text.tex.)
+
+ 3a. If the Current Maintainer is reachable and agrees to pass
+     maintenance of the Work to you, then this takes effect
+     immediately upon announcement.
+     
+  b. If the Current Maintainer is not reachable and the Copyright
+     Holder agrees that maintenance of the Work be passed to you,
+     then this takes effect immediately upon announcement.  
+    
+ 4.  If you make an `intention announcement' as described in 2b. above
+     and after three months your intention is challenged neither by
+     the Current Maintainer nor by the Copyright Holder nor by other
+     people, then you may arrange for the Work to be changed so as
+     to name you as the (new) Current Maintainer.
+     
+ 5.  If the previously unreachable Current Maintainer becomes
+     reachable once more within three months of a change completed
+     under the terms of 3b) or 4), then that Current Maintainer must
+     become or remain the Current Maintainer upon request provided
+     they then update their communication data within one month.
+
+A change in the Current Maintainer does not, of itself, alter the fact
+that the Work is distributed under the LPPL license.
+
+If you become the Current Maintainer of the Work, you should
+immediately provide, within the Work, a prominent and unambiguous
+statement of your status as Current Maintainer.  You should also
+announce your new status to the same pertinent community as
+in 2b) above.
+
+
+WHETHER AND HOW TO DISTRIBUTE WORKS UNDER THIS LICENSE
+======================================================
+
+This section contains important instructions, examples, and
+recommendations for authors who are considering distributing their
+works under this license.  These authors are addressed as `you' in
+this section.
+
+Choosing This License or Another License
+----------------------------------------
+
+If for any part of your work you want or need to use *distribution*
+conditions that differ significantly from those in this license, then
+do not refer to this license anywhere in your work but, instead,
+distribute your work under a different license.  You may use the text
+of this license as a model for your own license, but your license
+should not refer to the LPPL or otherwise give the impression that
+your work is distributed under the LPPL.
+
+The document `modguide.tex' in the base LaTeX distribution explains
+the motivation behind the conditions of this license.  It explains,
+for example, why distributing LaTeX under the GNU General Public
+License (GPL) was considered inappropriate.  Even if your work is
+unrelated to LaTeX, the discussion in `modguide.tex' may still be
+relevant, and authors intending to distribute their works under any
+license are encouraged to read it.
+
+A Recommendation on Modification Without Distribution
+-----------------------------------------------------
+
+It is wise never to modify a component of the Work, even for your own
+personal use, without also meeting the above conditions for
+distributing the modified component.  While you might intend that such
+modifications will never be distributed, often this will happen by
+accident -- you may forget that you have modified that component; or
+it may not occur to you when allowing others to access the modified
+version that you are thus distributing it and violating the conditions
+of this license in ways that could have legal implications and, worse,
+cause problems for the community.  It is therefore usually in your
+best interest to keep your copy of the Work identical with the public
+one.  Many works provide ways to control the behavior of that work
+without altering any of its licensed components.
+
+How to Use This License
+-----------------------
+
+To use this license, place in each of the components of your work both
+an explicit copyright notice including your name and the year the work
+was authored and/or last substantially modified.  Include also a
+statement that the distribution and/or modification of that
+component is constrained by the conditions in this license.
+
+Here is an example of such a notice and statement:
+
+  %% pig.dtx
+  %% Copyright 2005 M. Y. Name
+  %
+  % This work may be distributed and/or modified under the
+  % conditions of the LaTeX Project Public License, either version 1.3
+  % of this license or (at your option) any later version.
+  % The latest version of this license is in
+  %   http://www.latex-project.org/lppl.txt
+  % and version 1.3 or later is part of all distributions of LaTeX
+  % version 2005/12/01 or later.
+  %
+  % This work has the LPPL maintenance status `maintained'.
+  % 
+  % The Current Maintainer of this work is M. Y. Name.
+  %
+  % This work consists of the files pig.dtx and pig.ins
+  % and the derived file pig.sty.
+
+Given such a notice and statement in a file, the conditions
+given in this license document would apply, with the `Work' referring
+to the three files `pig.dtx', `pig.ins', and `pig.sty' (the last being
+generated from `pig.dtx' using `pig.ins'), the `Base Interpreter'
+referring to any `LaTeX-Format', and both `Copyright Holder' and
+`Current Maintainer' referring to the person `M. Y. Name'.
+
+If you do not want the Maintenance section of LPPL to apply to your
+Work, change `maintained' above into `author-maintained'.  
+However, we recommend that you use `maintained', as the Maintenance
+section was added in order to ensure that your Work remains useful to
+the community even when you can no longer maintain and support it
+yourself.
+
+Derived Works That Are Not Replacements
+---------------------------------------
+
+Several clauses of the LPPL specify means to provide reliability and
+stability for the user community. They therefore concern themselves
+with the case that a Derived Work is intended to be used as a
+(compatible or incompatible) replacement of the original Work. If
+this is not the case (e.g., if a few lines of code are reused for a
+completely different task), then clauses 6b and 6d shall not apply.
+
+
+Important Recommendations
+-------------------------
+
+ Defining What Constitutes the Work
+
+   The LPPL requires that distributions of the Work contain all the
+   files of the Work.  It is therefore important that you provide a
+   way for the licensee to determine which files constitute the Work.
+   This could, for example, be achieved by explicitly listing all the
+   files of the Work near the copyright notice of each file or by
+   using a line such as:
+
+    % This work consists of all files listed in manifest.txt.
+   
+   in that place.  In the absence of an unequivocal list it might be
+   impossible for the licensee to determine what is considered by you
+   to comprise the Work and, in such a case, the licensee would be
+   entitled to make reasonable conjectures as to which files comprise
+   the Work.

+# exam-zh: LaTeX template for Chinese exam
+
+Provides a class exam-zh.cls and its several module packages like exam-zh-question.sty and exam-zh-choices.sty, where these module packages can be used individually. 
+
+Although there are several excellent exam packages or classes uploaded before like exam and bhcexam , they don't fit the chinese style very well or they cannot be customized easily for chinese exam of all types like exams in primary school, junior high school, senior high school and even college. Those are the main reason why exam-zh was created.
+
+In exam-zh, you can
+
+- seperate the format and the content very well;
+- use choices environment to typeset choice items easily and automatically;
+- design the sealline easily;
+- use it in Windows, macOS and Linux;
+- ... (for more that you can do with it, please read the manual(in Chinese): `exam-zh-doc.pdf`

+  证明:$2 < \frac{1}{a} + \frac{1}{b} < \eu$。
+\end{problem}
+```
+
+
+## 使用方法
+
+下面简要叙述 `exam-zh` 的使用方法,**更多使用细节请阅读手册 `exam-zh-doc.pdf`。**
+### 西文和数学字体
+
+模板中可以设置西文和数学的字体。
+
+```tex
+\examsetup{
+  font      = times,
+  math-font = xits,
+}
+```
+
+西文字体 `font` 有以下选项:
+- `newcm`(默认)New Computer Modern
+- `lm` Latin Modern
+- `times` Times New Roman
+- `termes` TeX Gyre Termes
+- `stix` STIX Two
+- `xits` XITS
+- `libertinus` Libertinus
+
+数学字体 `math-font` 有以下选项:
+- `newcm`(默认)New Computer Modern Math
+- `lm` Latin Modern Math
+- `termes` TeX Gyre Termes Math
+- `stix` STIX Two Math
+- `xits` XITS Math
+- `libertinus` Libertinus Math
+- `cambria` Cambria Math
+
+注意数学字体使用了 `unicode-math` 宏包进行配置。
+
+
+### 题目环境 `question` 和 `problem`
+
+选择题和填空题使用 `question` 环境,解答题使用 `problem` 环境。两者的内容对齐方式不同。
+
+`question` 和 `problem` 环境还接受一个可选参数,其中可以使用以下 key—value 进行设置。
+- `answer-color` 答案的颜色(默认:`black`)。
+- `index` 题号。
+- `points` 题目的分数(默认:`0`)。
+- `show-paren` 是否显示选择题的括号(默认 `false`)。
+- `show-points` 是否显示题目的分数(默认 `auto`:选择题和填空题默认 `false`,解答题默认 `true`)。
+- `show-answer` 是否显示答案(默认:`false`)。
+- `top-sep` 题目上方垂直方向的空白距离(默认:`.5em plus .5em minus .2em`)。
+- `bottom-sep` 题目下方垂直方向的空白距离,与 `top-sep` 不叠加(默认:`.5em plus .5em minus .2em`)。
+
+其中 `index`、`show-points`、`show-answer`、`top-sep` 和 `bottom-sep` 可以使用 `\examsetup` 命令的 `choices` 层级进行全局设置。比如设置同一层级的多个选项:
+```latex
+\examsetup{
+  choices = {
+    show-points = true,
+    show-answer = true,
+  },
+}
+```
+也可以用斜线“/”表示层级并设置单项。
+```latex
+\examsetup{
+  question/show-points = true,
+  question/show-answer = true,
+}
+```
+
+
+### 选择题的括号 `\paren` 和填空 `\fillin`
+
+`\paren` 和 `\fillin` 命令分别生成选择题的括号和填空题的横线。这两个命令还分别接受一个可选参数作为题目的答案,如 `\paren[B]` 或 `\fillin[foo]`。当 `show-answer = true` 时则将答案显示在其中。
+
+需要注意的是,如果 `\fillin` 的参数中含有不配对的中括号时会报错,如 `\fillin[$(−\infty, 1]$]`。这时需要使用大括号将内容保护起来:`\fillin[{$(−\infty, 1]$}]`。
+
+`\fillin` 提供了样式的切换(目前就是下划线和括号两种):
+```latex
+\examsetup{
+  fillin = {
+    type = paren    % 括号风格 
+    % type = line    % 下划线风格
+  }
+}
+```
+也可以局部更改单个 `\fillin` 的样式:`\fill[type = paren][foo]`(有答案)或`\fill[type = paren][]`(无答案)
+
+
+### 选项环境 `choices`
+
+选择题的选项使用 `choices` 环境排版,可以自动根据内容的长度选择合适的列数并对齐。该环境的设计主要参考了 @xkwxdyy 的 [choices-l3](https://gitee.com/xkwxdyy/choices-l3) 和 [xchoices](https://gitee.com/xkwxdyy/xchoices) 项目。
+```latex
+\begin{choices}[label-pos = top-left]
+  \item $\{2\}$
+  \item $\{2, 3\}$
+  \item $\{3, 4\}$
+  \item $\{2, 3, 4\}$
+\end{choices}
+```
+其中的可选参数使用 key–value 的方式进行设置,除了 `label-pos` 外还包括以下选项。
+- `index`       第一个选项标签的计数器的数字值(默认为 `1`)。
+- `column-sep`  选项列之间的最小间隔(默认 `1em`)。
+- `columns`     强制按照该列数排版选项,如果为 0 则自动选择合适的列数(默认 `0`)。
+- `label-align`(可选:`left`, `center`, `right`;默认 `right`)标签内容的对齐方式。
+- `label`       标签的格式,类似 `enumitem` 可以在 `\Roman` 等命令后加 `*` 生成数字(默认 `\Alph*.`)。
+- `label-pos`   标签相对于选项内容的位置;`auto` 表示自动选择:如果内容高度超过两行时(通常是图片)标签位于左居中 `left`,否则位于左上角跟首行文字对齐(`top-left`)(可选:`auto`, `top-left`, `left`, `bottom`;默认 `auto`)。
+- `label-align` 标签内部的对齐方式。(可选:`left`, `center`, `right`;默认 `right`)
+- `label-sep`   标签与选项之间的距离(默认 `0.5em`)。
+- `label-width` 标签的宽度;如果宽度不足会自动调整为最长标签的宽度(默认 `0pt`)。
+- `max-columns` 选项的最大列数;排版选项时会优先尝试该列数,如果无法排下内容,依次将列数除以 2 并取整再进行尝试,直到可以排下全部选项(默认 `4`)。
+
+这些选项可以使用 `\examsetup` 命令的 `choices` 层级进行全局设置,类似 `question`。
+
+`exam-zh-choices` 模块还提供了 `\circlednumber` 命令调用中文字体生成带圈数字,该命令既可以接受 LaTeX2e 计数器的名字(如 `section`)作为参数,也可以接受数值表达式,比如 `\circlednumber{7}`,但仅限 0~50 的整数。而且有的字体可能没有提供 10 以上的字形,建议只对 10 以内的值使用。
+
+如果用户需要使用其他形式的数字作为 `choices` 的标签,需要使用 `\AddChoicesCounter` 命令将其添加进 `label` 选项的识别范围内(类似 `enumitem` 的 `\AddEnumerateCounter`)。它的格式是 `\AddChoicesCounter{⟨LaTeX command⟩}{⟨internal command⟩}{⟨widest label⟩}`,其中 `⟨LaTeX command⟩` 是在 `label` 选项中的形式,`⟨internal command⟩` 是内部的实现,`⟨widest label⟩` 是最宽的标签。比如带圈数字的添加方法:`\AddChoicesCounter{\circlednumber}{\__examzh_choices_circled_number:n}{1}`。
+
+
+### 解答环境 `solution` 和分数命令 `\score`
+
+```latex
+\begin{solution}
+  函数的定义域为 $(0, +\infty)$,
+  又 \[f^{\prime}(x) = 1 - \ln x-1 = -\ln x, \score{2}\]
+  当 $x \in(0, 1)$ 时, $f^{\prime}(x) > 0$, 当 $x \in(1, +\infty)$ 时, $f^{\prime}(x) < 0$,
+  故 $f(x)$ 的递增区间为 $(0,1)$, 递减区间为 $(1, +\infty)$.
+\end{solution}
+```
+用于解答题的解答环境,以及 `\score` 命令输出给分点,具体使用和相关键值请阅读手册。
+
+### 正体的数学常数
+
+按照国标,数学常数应使用正体。模板中提供了命令 `\eu` 和 `\iu` 分别表示自然对数的底“e”和虚数单位“i”。`\eu` 可以理解为 “e upright” 的缩写或者 “Euler's number” 的首字母,`\iu` 可以理解为 “i upright” 或 “imaginary unit” 的缩写,这样更方便记忆。圆周率“π”直接使用 `\uppi` 命令。
+
+
+### 密封线
+
+```latex
+  \examsetup{
+    sealline = {
+      show        = true,
+      % scope        = firstpage,
+      % scope        = oddpage,
+      scope        = everypage,
+      line-thickness       = 1pt,
+      line-xshift          = 8mm,
+      line-yshift          = 0mm,
+      line-type            = densely-dashed,
+      text                 = 密封线内不得答题,
+      text-xshift          = 11mm,
+      text-yshift          = 30mm,
+      circle-show          = true,
+      circle-start         = 0.07,
+      circle-end           = 0.92,
+      circle-step          = 3.5em,
+      circle-diameter      = 3mm,
+      circle-xshift        = 8mm,
+      odd-info-content     = {
+        {\kaishu 姓名}:{\underline{\hspace*{8em}}},
+        {\kaishu 准考证号}:{\underline{\hspace*{8em}}},
+        {\kaishu 考场号}:{\underline{\hspace*{8em}}},
+        {\kaishu 座位号}:{\underline{\hspace*{8em}}},
+      },
+      odd-info-seperator   = \hspace*{3em},
+      odd-info-align       = center,
+      odd-info-xshift      = 20mm,
+      odd-info-yshift      = 0mm
+    }
+  }
+```
+
+具体密封线参数含义从参数名称基本可以知道,具体的可以看手册 `exam-zh-doc.pdf`。

+\subsection{获取 \cls{exam-zh}}
+
+目前模块还处于开发阶段,用户目前以「下载发行版」的方式获取最新版本的 \cls{exam-zh}:
+
+\begin{enumerate}
+  \item 进入项目主页(\href{https://gitee.com/zepinglee/exam-zh}{gitee 项目主页} (界面见图~\ref{figure:gitee项目主页} )
+  \item 在右侧一列有“发行版”(gitee),并且有一个标签图标并有“vx.x.x - 20xx-xx-xx”字样,表示最新的发行版版本和发布时间,点击即可查看相关信息(如果想查看历史所有发行版信息,可以点击“发行版”右侧的“全部”(gitee))。
+  
+    发行版中一般由以下信息构成(\href{https://gitee.com/zepinglee/exam-zh/releases}{gitee 发行版} 界面见图~\ref{figure:gitee发行版})
+      \begin{itemize}
+        \item 更新文件的特别说明。如果没有,则表明此次更新只需要更新 \file{exam-zh.cls} 文件至最新\footnote{“更新 \meta{文件} 至最新”目前表示在发行版中下载最新版本的模板,并用其中所需要更新的 \meta{文件} 去替换本地的旧 \meta{文件}} 即可
+        \item 更新日志。 主要为此次发行版与上次发行版的不同,一般为“Added”、“Changed”、“Fixed”等信息
+        \item 模版及用户手册下载链接(“下载”部分)。一般用户只需要点击 \file{exam-zh-vx.x.x.zip} 进行模版下载即可,而下面的 \file{Source code} 为项目的整个源码,包括手册的源码,测试文件等,如果感兴趣的用户可以下载进行查看(当然,如果会使用 \cmd{git} 的用户也可以将整个 \cls{exam-zh} 项目 \cmd{clone} 下来查看)
+      \end{itemize}
+  \item 点击 \file{exam-zh-vx.x.x.zip} 进行下载,在本地解压即可

+% % \subsubsection{标准安装}
+
+% % 如果没有特殊理由,始终建议您使用宏包管理器安装 \cls{exam-zh}。
+% % 例如在 \TeXLive{} 中,执行(可能需要管理员权限)
+% % \begin{shellexample}[morekeywords={tlmgr,install}]
+% %   tlmgr install exam-zh
+% % \end{shellexample}
+% % 即可完成安装。
+
+% % 在 \TeXLive{} 和 \MiKTeX{} 中,您还可以通过图形界面进行安装,
+% % 此处不再赘述。
+
+% % \subsubsection{手动安装}
+
+% % 如果您需要从 CTAN 上自行下载并手动安装,较好的方法是使用 TDS
+% % 安装包:
+% % \begin{itemize}
+% %   \item 从 CTAN 上下载 \cls{exam-zh} 的
+% %     \href{http://mirror.ctan.org/install/macros/latex/contrib/exam-zh.tds.zip}{TDS 安装包};
+% %   \item 按目录结构将 \file{exam-zh.tds.zip} 中的文件复制到 \TeX{}
+% %     发行版的本地 TDS 根目录;
+% %   \item 执行 \bashcmd{mktexlsr} 刷新文件名数据库以完成安装。
+% % \end{itemize}
+% % %
+% % 您也可以从源代码直接生成模板(不推荐):
+% % \begin{itemize}
+% %   \item 打开 \href{https://gitee.com/stone-zeng/exam-zh}{项目主页},
+% %     点击“Code”按钮,并选择“Download ZIP”,下载 \file{exam-zh-main.zip};
+% %     如果您的电脑中安装有 git 程序,也可通过以下命令直接克隆代码仓库:
+% %     \begin{shellexample}[gobble=6,alsoletter={.},morekeywords={git,clone}]
+% %       git clone https://gitee.com/stone-zeng/exam-zh.git
+% %     \end{shellexample}
+% %   \item 解压并进入到 \file{source} 文件夹,执行以下命令以生成
+% %     模板的各组件:
+% %     \begin{shellexample}[gobble=6,morekeywords={xetex}]
+% %       xetex exam-zh.dtx
+% %     \end{shellexample}
+% %   \item 将生成的文档类(\file{.cls})、宏包(\file{.sty})以及
+% %     参数配置文件(\file{.def})复制到 \TeX{} 发行版本地 TDS 树
+% %     的 \path{texmf-local/tex/latex/exam-zh/} 目录下,并执行
+% %     \bashcmd{mktexlsr} 刷新文件名数据库,方可完成安装。
+% %   \item 使用 \cls{exam-zh} 撰写论文时,您还需要从代码仓库下的
+% %     \file{testfiles/support} 目录中复制 \file{fudan-name.pdf}
+% %     文件至工作目录,以确保封面中的校名图片可以正确显示。
+% % \end{itemize}
+
+% % \subsubsection{扁平化安装}
+
+% % 如果您不希望安装本模板,但需要立刻使用,也可以使用模板提供的安装脚本。
+% % 从 gitee 上获取代码仓库后,执行 \file{install-win.bat}(Windows 系统)
+% % 或 \file{install-linux.sh}(Linux 系统),所有需要的文件便会在
+% % \file{thesis} 文件夹中生成。

+\section{介绍}
+
+试卷排版是中小学教师经常遇到的需求,目前在网上可以找到的试卷排版相关文类或宏包有:
+\begin{itemize}
+  \item Philip Hirschhorn:\href{https://www.ctan.org/pkg/exam}{exam}
+  \item 吕荐瑞:\href{https://www.ctan.org/pkg/jnuexam}{jnuexam}
+  \item 胡振震:\href{https://github.com/hushidong/simplexam}{simplexam}
+  \item 鲍宏昌:\href{https://github.com/mathedu4all/bhcexam}{BHCexam}

+  \item 唐绍东:\href{https://github.com/shaodongtang/CMC}{CMC}
+  \item sd44:\href{https://github.com/sd44/DANexam}{DANexam}
+\end{itemize}
+
+但是大部分没有经过系统设计以及后续进一步的维护,\href{https://www.ctan.org/pkg/exam}{exam} 大部分设置与国内习惯不同,调试配置起来增加用户的使用成本 \href{https://www.ctan.org/pkg/jnuexam}{jnuexam}、\href{https://github.com/shaodongtang/CMC}{CMC} 是比较“定制化”的,也无法顺利地进行迁移使用。
+
+但是上述前人所做的工作值得参考,比如 \cls{exam-zh} 的 A4 和 A3 页面切换就参考了 \href{https://www.ctan.org/pkg/jnuexam}{jnuexam} 项目。
+
+本模板将借鉴前辈经验,重新设计,并使用 \LaTeX3 编写,以适应 \TeX 技术发展潮流; 同时还将构建一套简洁的接口,方便用户使用。

+% !TeX root = ../exam-zh-doc.tex
+
+\section{使用说明}
+
+\subsection{基本用法}
+
+以下是一份简单的 \TeX{} 文档,它演示了 \cls{exam-zh} 的最基本用法:
+
+\begin{latexcode}[deletetexcs={\documentclass},
+    moretexcs={\chapter},morekeywords={\documentclass},
+    emph={[2]document}]
+  % main.tex
+  \documentclass{exam-zh}
+  \begin{document}
+    \section{Welcome to exam-zh!}
+    你好,\LaTeX{}!
+  \end{document}
+\end{latexcode}
+
+
+按照~\ref{subsec:编译方式} 小节中的方式编译,您应当得到一篇 1 页的文档。
+
+
+\subsection{编译方式} \label{subsec:编译方式}
+
+本模板不支持 \pdfTeX{} 引擎,仅支持使用 \XeLaTeX{} 。为了生成正确的目录、脚注以及交叉引用,您至少需要连续编译两次。
+
+以下代码中,假设您的 \TeX{} 源文件名为 \file{example.tex}。请在命令行中执行
+\begin{shellcode}[morekeywords={xelatex}]
+  xelatex example
+\end{shellcode}
+
+
+\subsection{模板选项}
+
+所谓“模板选项”,指需要在引入文档类的时候指定的选项:
+\begin{latexcode}[deletetexcs={\documentclass},
+    morekeywords={\documentclass}]
+  \documentclass(*\oarg{模板选项}*){exam-zh}
+\end{latexcode}
+
+有些模板选项为布尔型,它们只能在 \opt{true} 和 \opt{false}
+中取值。对于这些选项,\kvopt{\meta{选项}}{true} 中的“|= true|”
+可以省略。
+
+\cls{exam-zh} 的模版选项接口与 \cls{ctexart} 相同,具体可 \cmd{texdoc ctex} 查阅 \pkg{ctex} 宏包文档。
+
+
+\subsection{命令和环境介绍}
+
+\subsubsection{正体的数学常数}
+
+\begin{function}{\eu}
+  正体的自然对数的底“e”。
+\end{function}
+
+\begin{function}{\iu}
+  正体的虚数单位“i”。
+\end{function}
+
+\tn{eu} 可以理解为 “e upright” 的缩写或者 “Euler's number” 的首字母,\tn{iu} 可以理解为 “i upright” 或 “imaginary unit” 的缩写,这样更方便记忆。
+
+\begin{latexexample}{\tn{eu} 和 \tn{iu} 的效果}
+  $\eu \quad \iu$
+\end{latexexample}
+
+
+\subsubsection{优化的命令环境}
+
+\cls{exam-zh} 对一些命令环境进行了优化,方便用户使用。
+
+\begin{function}{\vec}
+  \begin{ccnusyntax}[emph={[1]vec}]
+    \vec(*\marg{content}*)
+  \end{ccnusyntax}
+  向量命令。当只有一个字符的时候默认加粗斜体,两个及两个以上字符则加箭头。
+\end{function}
+
+\begin{latexexample}{\tn{vec} 示例}
+  $\vec{a} \quad \vec{AB}$
+\end{latexexample}
+
+
+\subsubsection{中国化数学符号}
+
+中国的初高中教材中一些数学符号和 \LaTeX{} 默认的或者是 \pkg{amsmath} 等宏包提供的符号有差异,于是 \cls{exam-zh} 用 \TikZ 重新绘制了部分符号。
+
+\begin{function}{\parallelogram}
+  平行四边形。$\parallelogram$
+\end{function}
+
+\begin{function}{\parallel,\nparallel}
+  平行和不平行。$\parallel \, \nparallel$
+\end{function}
+
+\begin{function}{\paralleleq}
+  平行且相等。$\paralleleq$
+  \examsetup{symbols/paralleleq-type = perpendicular}
+  \, $\paralleleq$。由~\ref{subsubsec:参数-中国化数学符号} 节的键值可以控制倾斜和垂直两个不同类型。
+\end{function}
+

+%   \begin{ccnusyntax}[emph={[1]}]
+    
+%   \end{ccnusyntax}
+% \end{function}
+
+
+% \subsubsection{中文字体}
+
+% 在语文试卷中可能需要不同的字体,比如楷体等,在 \cls{exam-zh} 中,不使用 \tn{kaiti} 等命令(一般会有报错),推荐使用 \tn{itshape} 等命令:
+% \begin{latexexample}{不同字体命令效果}
+%   测试 {\normalfont 测试}
+
+%   加粗 {\bfseries 测试}
+
+%   黑体 {\sffamily 测试}

+      choices = {

+\begin{function}{\AddChoicesCounter}
+  \begin{ccnusyntax}[emph={[2]\AddChoicesCounter}]
+    \AddChoicesCounter(*\marg{LaTeX command}*)(*\marg{internal command}*)
+  \end{ccnusyntax}
+  如果用户需要使用其它形式的数字作为 \env{choices} 环境的标签,需要使用 \tn{AddChoicesCounter} 命令将其添加进 \opt{label} 选项的识别范围内(类似 \pkg{enumitem} 宏包的 \tn{AddEnumerateCounter} )。其中 \meta{LaTeX command} 是在 \opt{label} 选项中的形式,\meta{internal command} 是内部的实现,\meta{widest label} 是最宽的标签。比如带圈数字的添加方法:

+    \circlednumber*(*\meta{数字或计数器名字}*)
+  \end{ccnusyntax}
+  带圈数字命令。不带星号的基于字体开发,带星号的基于 \TikZ 开发。|\circlednumber| 仅接受 0~50 的输入值,而 |\circlednumber*| 无限制。
+  \begin{latexexample}{\tn{circlednumber} 的使用示例}

+  \end{latexexample}
+\end{function}
+
+
+\subsubsection{填空题}
+
+\begin{function}[updated = 2022-07-27]{\fillin}
+  \begin{ccnusyntax}[emph={[2]\fillin}]
+    \fillin(*\oarg{键值列表}*)(*\oarg{答案}*)
+    \fillin*(*\oarg{键值列表}*)(*\oarg{答案}*)
+  \end{ccnusyntax}
+  填空(下划线或括号)。\meta{答案} 可以受~\ref{subsubsec:参数-题干} 节的 \cmd{question/show-answer} 键值控制隐藏。\meta{键值列表} 见~\ref{subsubsec:参数-填空题} 节。\tn{fillin} 不可换行,但是会自动根据内容深度提升基线(比如排版分数不会“压线”);\tn{fillin*} 可以自动换行但是没有前者的功能,且 \tn{fillin*} 的换行功能只适用于 \kvopt{fillin/type}{line}、\kvopt{fillin/type}{paren} 和 \kvopt{fillin/type}{blank}。
+\end{function}
+
+注意,\tn{fillin} 命令经过处理,|\fillin[<1>]| 表示 |\fillin[<答案>]|(而不是通常定义两个可选参数命令,若只写一个的时候默认为第一个参数),而如果仅仅改变 \tn{fillin} 的类型(见下)而不输入答案,则需要使用 |\fillin[type=paren][]|。这样设计是考虑到:大部分时候都是无答案和输入答案两种情况,而单独改某一个 \tn{fillin} 的类型的情况很少,一般都是一些题目统一改,这个时候在需要修改的 \tn{fillin} 之前使用
+  \begin{latexcode}[gobble=4]
+    \examsetup{
+      fillin/type = paren
+    }
+  \end{latexcode}
+  更改即可。如果后续需要换回来,则只需要使用
+  \begin{latexcode}[gobble=4]
+    \examsetup{
+      fillin/type = line
+    }
+  \end{latexcode}
+  即可。
+
+需要注意的是,如果 \tn{fillin} 的参数重含有不配对的中括号时会报错,如 |\fillin[$(−\infty, 1]$]|。这时需要使用大括号将内容保护起来:|\fillin[{$(−\infty, 1]$}]|。
+
+
+\begin{function}[added = 2022-07-21]{\AddFillinCounter}
+  \begin{ccnusyntax}[emph={[1]\AddFillinCounter}]
+    \AddFillinCounter(*\marg{LaTeX command}*)(*\marg{internal command}*)
+  \end{ccnusyntax}
+  如果用户需要使用其它形式的数字作为 \kvopt{fillin/no-answer-type}{counter} 下 \opt{counter} 的标签,需要使用 \tn{AddFillinCounter} 命令将其添加进 \opt{label} 选项的识别范围内(类似 \pkg{enumitem} 宏包的 \tn{AddEnumerateCounter} )。其中 \meta{LaTeX command} 是在 \opt{label} 选项中的形式,\meta{internal command} 是内部的实现,\meta{widest label} 是最宽的标签。比如带圈数字的添加方法:
+  \begin{latexcode}[gobble=4]
+    \AddFillinCounter{\circlednumber}{\__examzh_fillin_circled_number:n}
+  \end{latexcode}
+\end{function}
+
+
+\subsubsection{判断题}
+
+作为 \tn{paren} 和 \tn{fillin} 命令的应用可以实现判断题效果:
+\begingroup
+\examsetup{
+  question/index=0
+}
+\begin{latexexample}{\tn{paren} 和 \tn{fillin} 命令的应用:判断题}
+  \examsetup{
+    question/show-answer = true,
+    fillin/type = paren,
+    paren/show-paren = true
+  }
+  \newcommand{\true}{$\surd$}
+  \newcommand{\false}{$\times$}
+
+  \begin{question}
+    $1 + 1 = 2$ \paren[对]
+  \end{question}
+
+  \begin{question}
+    $1 + 1 = 3$ \fillin[错]
+  \end{question}
+
+  \begin{question}
+    $1 + 1 = 2$ \paren[\true]
+  \end{question}
+
+  \begin{question}
+    $1 + 1 = 3$ \fillin[\false]
+  \end{question}
+\end{latexexample}
+\endgroup
+
+由于使用“对错”还是“叉勾”因人而异,所以本模版没有固定,但结合上面的例子为用户提供一种“自定义”思路(基于 \tn{fillin} 为例):
+\ExplSyntaxOn
+\cs_undefine:N \true
+\cs_undefine:N \false
+\ExplSyntaxOff
+\examsetup{
+  question/index = 0
+}
+\begingroup

+  \begin{ccnusyntax}[emph={[1]score}]
+    \score(*\marg{分数}*)
+  \end{ccnusyntax}
+  \env{solution} 环境中得分点的得分命令。若在行间公式使用,则需要编译两次产生虚线。
+\end{function}
+
+\begin{latexexample}{\tn{score} 命令示例}
+  \begin{solution}
+    函数的定义域为 $(0, +\infty)$,
+    又 \[f^{\prime}(x) = 1 - \ln x-1 = -\ln x, \score{2}\]
+    当 $x \in(0, 1)$ 时, $f^{\prime}(x) > 0$, 当 $x \in(1, +\infty)$ 时, $f^{\prime}(x) < 0$.
+
+    故 $f(x)$ 的递增区间为 $(0,1)$, \score{1} 递减区间为 $(1, +\infty)$. \score{1}
+  \end{solution}

+\end{function}
+
+
+\subsubsection{方格}

+
+\subsubsection{试卷合集}
+
+\cls{exam-zh} 不仅可以排版单份的试卷,也可以通过 \tn{chapter} 排版多份试卷,构成试卷合集。一般排版多份试卷会用到下面的命令:
+
+\begin{function}{\tableofcontents}

+\end{function}
+
+\begin{function}{\chapter}
+  用于排一份的试卷标题。并可以用 \opt{page/show-chapter} 键值控制显示与否。

+    \ExamPrintAnswerSet(*\oarg{cmd list}\marg{key-val list}*)
+  \end{ccnusyntax}
+  设置用户对于师生两版的第二个版本 PDF 的导言区设置(可以自由选择第二个版本的键值设置,自由度高)。其中 \meta{cmd list} 和 \meta{key-val list} 的内容均用西文逗号分隔。\emph{注意第二个版本的设置是本 \file{.tex} 文件的设置基础之后加上 \tn{ExamPrintAnswerSet} 生成的,所以键值的使用要注意。(比如本 \file{.tex} 文件中设置了 \kvopt{fillin/show-answer}{true},如果 \tn{ExamPrintAnswerSet} 不写 \kvopt{fillin/show-answer}{false} 的话,则还是按照 \kvopt{fillin/show-answer}{true} 的设置编译的)}
+  \begin{itemize}

+选项通常是 \kvopt{\meta{key}}{\meta{value}} 的形式。部分选项的
+\meta{value} 可以省略。对于同一项,后面的设置将会覆盖前面的设置。
+在下文的说明中,将用\textbf{粗体}表示默认值。
+
+\cs{examsetup} 采用 \LaTeX3 风格的键值设置,支持不同类型以及多种
+层次的选项设定。键值列表中,“|=|”左右的空格不影响设置;但需注意,
+参数列表中\emph{不可以出现空行}。
+
+与模板选项相同,布尔型的参数可以省略 \kvopt{\meta{选项}}{true}
+中的“\kvopt{}{true}”。
+
+另有一些选项包含子选项,如 \opt{page} 和 \opt{choices} 等。它们可以
+按如下两种等价方式来设定:
