+The typed-checklist package
+===========================
+
+Copyright (C) 2013-2016 Richard Gay
+
+Released under the [LaTeX Project Public License](http://www.latex-project.org/lppl/) version 1.2 or later
+
+## Purpose
+
+The main goal of the `typed-checklist` package is to provide means for
+typesetting checklists in a way that stipulates users to explicitly
+distinguish checklists for goals, for tasks, for artifacts, and for
+milestones - i.e., the *type* of checklist entries.
+The intention behind this is that a user of the package is coerced to
+think about what kind of entries he/she adds to the checklist. This
+shall yield a clearer result and, in the long run, help with training to
+distinguish entries of different types.
+
+## Availability
+
+The `typed-checklist` package is on [CTAN](http://www.ctan.org/pkg/typed-checklist),
+where you can also find the [documentation](http://mirrors.ctan.org/macros/latex/contrib/typed-checklist/typed-checklist.pdf),
+as well as on [github](https://github.com/Ri-Ga/typed-checklist).
+
+## Manual Installation
+
+The `typed-checklist` package comes with (at least) the following files
+* typed-checklist.ins
+* typed-checklist.dtx
+* README.md
+
+and possibly also with
+* Makefile
+* typed-checklist.pdf (generated from typed-checklist.dtx)
+* typed-checklist.sty (generated from typed-checklist.dtx)
+
+To install the `typed-checklist` package, you additionally need
+* docstrip.tex
+
+To build the package (`typed-checklist.sty`), run one of the following
+```
+    latex typed-checklist.ins
+    make package (needs Makefile)
+```
+
+Put the resulting `typed-checklist.sty` somewhere where LaTeX can find it.
+Read the documentation of your LaTeX system to find out where this
+might be.
+
+## Building Documentation
+
+To build the documentation of the `typed-checklist` package,
+you additionally need the following classes and packages
+(including their dependencies):
+* ltxdoc
+* idxlayout
+* etoolbox
+* xcolor
+* soul
+* csquotes
+* enumitem
+* booktabs
+* showexpl
+* pbox
+* skull
+* hypdoc
+* xkeyval
+* etoolbox
+* xcolor
+* asciilist
+* bbding
+* marginnote
+* longtable
+* tabu
+
+as well as
+* pdflatex
+
+To build the documentation (`typed-checklist.pdf`), either run
+```
+    make docs
+```
+or the following sequence of commands
+```
+    pdflatex typed-checklist.dtx
+    makeindex -s gind.ist -o typed-checklist.ind typed-checklist.idx
+    makeindex -s gglo.ist -o typed-checklist.gls typed-checklist.glo
+    pdflatex typed-checklist.dtx
+    pdflatex typed-checklist.dtx
+```

+%
+% \begin{abstract}
+% The main goal of the \textsf{typed-checklist} package is to provide
+% means for typesetting checklists in a way that stipulates users to
+% explicitly distinguish checklists for goals, for tasks, for
+% artifacts, and for milestones -- i.e., the \emph{type} of checklist
+% entries.
+% The intention behind this is that a user of the package is coerced to
+% think about what kind of entries he/she adds to the checklist. This
+% shall yield a clearer result and, in the long run, help with training
+% to distinguish entries of different types.
+% \end{abstract}
+%
+% \section{Motivation and Disambiguation}
+%
+% The development of this package was driven with two goals in mind:
+% \begin{enumerate}
+% \item having a package with which one can easily typeset checklists and
+%   in a way that separates content from layout;
+% \item having a thinking tool that helps distinguishing between goals
+%   and tasks.
+% \end{enumerate}
+% The first goal felt natural to me since from time to time I manage
+% checklists in \LaTeX{} documents, mostly because I like it when the
+% result looks typeset nicely.
+% The second goal arose from an observation about some of my own
+% checklists as well as checklists created by others: Quite frequently,
+% the checklists mixed goals and tasks or had goals formulated as tasks
+% and vice versa. As a consequence, the checklists were formulated
+% unnecessarily unclear and were more difficult to understand by others.
+%
+% This package approaches particularly the second goal by providing
+% checklists with a \emph{type}. A checklist of a particular type shall
+% then only contain entries of this type.
+%
+% While the package allows one to define custom checklist types (see
+% Section~\ref{sec:customizing}), it comes with four basic types:
+% |Artifact|, |Goal|, |Milestone|, and |Task|. In this documentation,
+% the terms \enquote{artifact}, \enquote{goal}, \enquote{milestone}, and
+% \enquote{task} will be used along the lines of the following
+% definitions (highlights added):
+% \begin{description}[leftmargin=!,labelwidth=\widthof{\bfseries milestone:}]
+% \item[artifact:]
+%   \begin{Dict}
+%   \item\textquote[\href{https://en.wiktionary.org/wiki/artifact}{Wiktionary}]{An \hl{object} made or shaped by human hand.}
+%   \end{Dict}
+% \item[goal:]
+%   \begin{Dict}
+%   \item\textquote[\href{http://www.businessdictionary.com/definition/goal.html}{BusinessDictionary.com}]{An observable and measurable \hl{end result} having one or more objectives to be achieved within a more or less fixed timeframe.}
+%   \item\textquote[\href{http://www.merriam-webster.com/dictionary/goal}{Merriam-Webster}]{the \hl{end} toward which effort is directed}
+%   \item\textquote[\href{http://www.oxforddictionaries.com/de/definition/englisch_usa/goal?q=Goal}{Oxford Dictionaries}]{The object of a person’s ambition or effort; an aim or desired \hl{result}}
+%   \item\textquote[\href{https://en.wiktionary.org/wiki/goal}{Wiktionary}]{A \hl{result} that one is attempting to achieve.}
+%   \end{Dict}
+% \item[milestone:]
+%   \begin{Dict}
+%   \item\textquote[\href{https://en.wiktionary.org/wiki/milestone}{Wiktionary}]{An important event \textelp{} in the life of some project}
+%   \end{Dict}
+% \item[task:]
+%   \begin{Dict}
+%   \item\textquote[\href{http://www.merriam-webster.com/dictionary/task}{Merriam-Webster}]{a usually assigned \hl{piece of work} often to be finished within a certain time}
+%   \item\textquote[\href{https://en.wiktionary.org/wiki/task}{Wiktionary}]{A \hl{piece of work} done as part of one’s duties.}
+%   \end{Dict}
+% \end{description}
+% We could connect the four terms as follows.
+% Typically, the \textquote{piece of work} that constitutes a task is
+% performed for achieving some goal. One can also say that a goal
+% serves as a reference point for why and how one should perform certain
+% tasks. A goal can be that a particular artifact or set of artifacts is
+% available at some point in time. A milestone is a group of goals whose
+% achievement is of importance for something bigger.
+% These connections suggest that nesting different types of checklists
+% is reasonable -- and it is supported by the \textsf{typed-checklist}
+% package.
+%
+% \section{Recommendations for Structuring Checklists}
+%
+% The \textsf{typed-checklist} package allows checklists of different
+% types as well as of identical types to be nested. That is, within a
+% checklist, another checklist can be placed. The following list
+% discusses some combinations of nested checklist types and provides
+% some recommendations of what types could be nested for
+% particular purposes and what types should better not be nested.
+% \begin{enumerate}
+% \item tasks in goals\Good
+%   This nesting combination could be used for listing tasks whose
+%   accomplishment would lead to the satisfaction of the
+%   superordinated goal.
+% \item goals in goals\Good
+%   This nesting combination could be used for explicitly listing
+%   sub-goals (and sub-sub-goals and \ldots) to a goal. That is,
+%   using this nesting combination you can express the result of
+%   breaking down goals into sub-goals. Used reasonably, this nesting
+%   should be used in a way that the sub-goals, when achieved, yield
+%   the superordinated goal to be achieved (at least with high
+%   probability and/or to a significant extent).
+% \item tasks in tasks\Good
+%   This nesting combination could be used for listing all sub-tasks
+%   to a task. That is, using this nesting combination you can express
+%   the result of breaking down tasks into sub-tasks.
+% \item goals in milestones\Good
+%   This nesting combination could be used for listing all goals that
+%   must be achieved, at a particular date, for calling a
+%   milestone achieved.
+% \item artifacts in milestones\Good
+%   This nesting combination could be used for listing all artifacts
+%   that must exist, at a particular date, for calling a milestone
+%   achieved.
+% \item goals in tasks\Evil
+%   This nesting lacks a clearly recognizable meaning. The use of this
+%   kind of nesting might be an indicator for a misunderstanding of
+%   goals or tasks, or it might be the result of too vague
+%   formulations of goals or tasks that do not reveal that something
+%   is wrong in the planning.
+% \item milestones in milestones\Evil
+%   A milestone, as cited, is an important event. Having
+%   sub-milestones would blur the notion of important events by
+%   introducing multiple levels of important events. Instead of
+%   nesting milestones, one could nest goals or artifacts in
+%   milestones to express intermediate stages of a milestone.
+% \end{enumerate}
+%
+% \section{Basic Usage}
+%
+% The following example demonstrates a basic use of the package.
+%
+% \begin{LTXexample}
+% \documentclass{article}
+% \usepackage{typed-checklist}
+% \begin{document}
+% \begin{CheckList}{Goal}
+%   \Goal{open}{I have a trendy haircut}
+%     \begin{CheckList}{Task}
+%       \Task{done}{find a hairdresser}
+%       \Task{started}{make an appointment}
+%       \Task{open}{go to the hairdresser}
+%     \end{CheckList}
+%   \Goal{achieved}{I have a typed checklist}
+% \end{CheckList}
+% \end{document}
+% \end{LTXexample}
+% The example contains a checklist for goals and the first goal contains
+% a checklist for tasks. Checklist entries have a status and a
+% description. In the typeset result, the checklist type is reflected by
+% a basic symbol (an empty circle for a goal and an empty box for a
+% task) that is decorated depending on the status (e.g., with a
+% check mark). The entry's description is shown next to the symbol.
+%
+% \NiceDescribeEnv{CheckList}{\oarg{options}\marg{type}}
+% Checklists are created via the |CheckList| environment.
+% The \meta{type} parameter determines the type of all checklist entries
+% in the environment. The \textsf{typed-checklist} package comes with
+% four predefined types: |Goal|, |Task|, |Artifact|, and |Milestone|.
+% Each of the types comes with a macro of the same name as the type.
+% With this macro, the entries of the checklist can be created.
+%
+% The \meta{options} can be a comma-separated list of
+% \meta{key}|=|\meta{value} pairs. The following keys can be set:
+% \begin{itemize}
+% \item With the |layout| key, the layout of the checklist can be
+%   chosen. Supported layouts are |list| (a list-based layout with
+%   each entry being a list item), |table| (a table-based layout with
+%   each entry being a table row), and |hidden| (a layout that does
+%   not display the entries).
+% \end{itemize}
+% A checklist can be viewed as a list of entries (even if the layout is
+% actually tabular). The macros for creating the entries are described
+% next.
+%
+% \NiceDescribeMacro{\Goal}{\oarg{options}\marg{status}\marg{description}}
+% Inside a checklist of type |Goal|, the |\Goal| macro specifies a goal.
+% Every goal comes at least with a \meta{description} and a
+% \meta{status}. The \meta{description} can, technically, be anything
+% that is displayable in the given checklist |layout|. However, for the
+% purpose of a meaningful checklist, the \meta{description} should be a
+% clear description of a goal in a full sentence\footnote{Incomplete
+% sentences typically tend to be less clear.}. The \meta{status}
+% parameter selects the most recent known status of the goal. This
+% parameter can assume any of the following values\footnote{See
+% Section~\ref{sec:AddingStates} to find out how custom states can be
+% defined}:
+% \begin{longtabu}{@{}CX@{}}
+% achieved &
+%   This value specifies that the goal has been achieved. Depending on
+%   how the \meta{description} was formulated, this might mean that in
+%   the respective situation the \meta{description} is a true
+%   statement.\\
+% dropped &
+%   This value specifies that the goal was a goal once but is no longer
+%   a goal that shall be pursued. This value allows one to preserve
+%   historical information about a checklist.\\
+% unclear &
+%   This value specifies that the goal somehow exists but is not yet
+%   clear enough to those who pursue the goal (or: who typeset the
+%   checklist) for actually pursuing the goal.\\
+% open &
+%   This value specifies the negation of all aforementioned values. That
+%   is, the goal is clear but neither achieved yet nor dropped.\\
+% \end{longtabu}
+% The \meta{options}\label{EntryOptions} allow one to specify further
+% details about the goal. The \meta{options} must be a possibly empty,
+% comma-separated list of \meta{key}|=|\meta{value} pairs. The
+% \meta{key} must be one of the following values\footnote{See
+% Section~\ref{sec:AddingEntryKeys} to find out how custom \meta{key}s
+% can be defined.}:
+% \begin{longtabu}{@{}CX@{}}
+% who &
+%   This option declares who is responsible for making sure the
+%   checklist entry is addressed. Remember to put the value in curly
+%   braces if it contains commas.\\
+% deadline &
+%   This option declares a deadline for the checklist entry, i.e., a date
+%   until which the entry must be addressed at latest. The deadline must
+%   be of the format ``\meta{day}.\meta{month}.\meta{year}''.\\
+% label &
+%   This option declares a label name for the checklist entry. This is
+%   analogous to the \cs{label} macro of \LaTeX. The entry's label is
+%   displayed next to the entry. A reference to a labeled checklist
+%   entry can be made using the \cs{ref} macro of \LaTeX{}.\\
+% \end{longtabu}
+%
+% \NiceDescribeMacro{\Task}{\oarg{options}\marg{status}\marg{description}}
+% Inside a checklist of type |Task|, the |\Task| macro specifies a task.
+% Every task comes at least with a \meta{description} and a
+% \meta{status}. The \meta{description} can, technically, be anything
+% that is displayable in the given checklist |layout|. However, for the
+% purpose of a meaningful checklist, the \meta{description} should be a
+% clear description of a task in a full sentence, possibly in imperative
+% form\footnote{For a \meta{description} in imperative form, the
+% \texttt{who} option can be used to specify who is addressed by the
+% \meta{description}.}. The \meta{status} parameter selects the most
+% recent known status of the task. This parameter can assume any of the
+% following values:
+% \begin{longtabu}{@{}CX@{}}
+% open &
+%   This value specifies that the task is still planned but has not
+%   yet been started.\\
+% dropped &
+%   This value specifies that the task was originally planned but is
+%   no longer part of the plan.\\
+% unclear &
+%   This value specifies that the task itself or its current status is
+%   unclear.\\
+% started &
+%   This value specifies that someone has started to perform the task,
+%   but has not finished yet.\\
+% done &
+%   This value specifies that someone has accomplished the task.
+%   Depending on the clarity and level of detail of the
+%   \meta{description}, whether accomplishing the task yielded a
+%   meaningful outcome might be more or less subjective to the person
+%   who accomplished the task.\\
+% \end{longtabu}
+% The \meta{options} parameter can be set as documented for the
+% |\Goal| macro on page~\pageref{EntryOptions}.
+%
+% \NiceDescribeMacro{\Artifact}{\oarg{options}\marg{status}\marg{description}}
+% Inside a checklist of type |Artifact|, the |\Artifact| macro specifies
+% an artifact.
+% Every artifact comes at least with a \meta{description} and a
+% \meta{status}. The \meta{description} can, technically, be anything
+% that is displayable in the given checklist |layout|. However, for the
+% purpose of a meaningful checklist, the \meta{description} should be a
+% clear identification of the artifact and its required attributes.
+% The \meta{status} parameter selects the most recent known status of
+% the artifact. This parameter can assume any of the following values:
+% \begin{longtabu}{@{}CX@{}}
+% missing &
+%   This value specifies that the artifact is missing yet.\\
+% dropped &
+%   This value specifies that the artifact was originally planned but
+%   is no longer part of the plan.\\
+% unclear &
+%   This value specifies that the artifact itself or its current
+%   status is unclear.\\
+% incomplete &
+%   This value specifies that some non-negligible parts of the
+%   artifact exist but the artifact does not yet exist in its final
+%   form\\
+% available &
+%   This value specifies that the artifact exists and available.\\
+% \end{longtabu}
+%
+% \NiceDescribeMacro{\Milestone}{\oarg{options}\marg{status}\marg{description}}
+% Inside a checklist of type |Milestone|, the |\Milestone| macro
+% specifies a milestone.
+% Every milestone comes at least with a \meta{description} and a
+% \meta{status}. The \meta{description} can, technically, be anything
+% that is displayable in the given checklist |layout|. However, for the
+% purpose of a meaningful checklist, the \meta{description} should be a
+% clear identification of what has to exist or must have been
+% fulfilled.
+% The \meta{status} parameter selects the most recent known status of
+% the milestone. This parameter can assume any of the following values:
+% \begin{longtabu}{@{}CX@{}}
+% open &
+%   This value specifies that the milestone has not yet been achieved.\\
+% achieved &
+%   This value specifies that the milestone has been achieved.\\
+% \end{longtabu}
+%
+% \subsection{Example}\label{sec:NestOptExample}
+% The following example shows the use of nested checklists and the use
+% of the options |layout|, |deadline|, |label|, and |who|. Note that
+% deadlines normally are displayed in the margin of the document, which
+% is not the case in this documentation.
+% \begin{LTXexample}[pos=t,preset=\FakeRefs]
+% \begin{CheckList}{Goal}
+%   \Goal[deadline=31.12.999]{achieved}{No Y1K problems}
+%   \Goal[who=John,deadline=31.12.1999]{open}{No Y2K problems}
+%     \begin{CheckList}[layout=table]{Task}
+%       \Task[who=John,label=Fix1]{started}{Repair all programs}
+%       \Task[who=Mankind,deadline=31.12.1999]
+%           {open}{Just turn off all computers, if \ref{Fix1} fails}
+%     \end{CheckList}
+%   \Goal[deadline=31.12.9999]{unclear}{No Y10K problems}
+% \end{CheckList}
+% \end{LTXexample}
+%
+%
+% \section{Customized Checklists}\label{sec:customizing}
+%
+% The \textsf{typed-checklist} package comes with a set of layouts,
+% checklist types, checklist entry states, and checklist entry
+% options. These together shall provide everything needed for
+% typesetting even checklists with complex structures. When the
+% default is not enough, you can use the macros described in this
+% section for creating your own layouts, types, states, and options.
+%
+% \subsection{Defining Checklist Types}\label{sec:AddingTypes}
+%
+% \NiceDescribeMacro{\CheckListAddType}{\marg{type}\marg{symbol}}
+% Using this macro, you can add a new checklist type. The name of the
+% type, i.e., the name that can be used as argument to the |CheckList|
+% environment, is specified by \meta{type}.
+% The basic symbol of entries belonging to this checklist type will be
+% \meta{symbol} (e.g., an empty box or circle). All status-symbols (see
+% Section~\ref{sec:AddingStates}) are drawn on top of \meta{symbol}.
+%
+% Note that the \textsf{typed-checklist} package uses this macro also
+% for creating each of the four default checklist types.
+%
+% \subsection{Defining Checklist Entry States}\label{sec:AddingStates}
+%
+% \NiceDescribeMacro{\CheckListAddStatus}{\marg{types}\marg{status}\marg{isclosed}\marg{symbol}}
+% Using this macro, you can add a new checklist entry status for
+% selected checklist types. The name of the status to define is
+% specified by the \meta{status} argument. The checklist types to which
+% the status is added, are provided by the \meta{types} argument, a
+% comma-separated list.
+% The \meta{symbol} is \LaTeX{} code of a symbol
+% that is put on top of the checklist type's symbol. The \meta{isclosed}
+% parameter must be one of |true| or |false|. A value of |true|
+% indicates that the status of the entry corresponds to the entry being
+% closed. This particularly means that no warning will be shown if the
+% deadline of an entry with this status is passed. A value of |false|
+% for \meta{isclosed} indicates that the \meta{status} corresponds to
+% the entry not yet being closed.
+%
+% Note that the \textsf{typed-checklist} package uses this macro also
+% for creating the provided states of the four default checklist types.
+%
+% \subsection{Defining Checklist Layouts}\label{sec:AddingEntryKeys}
+% \NiceDescribeMacro{\CheckListDeclareLayout}{\marg{name}\marg{fields}\marg{begin}\marg{end}}
+% Using this macro, you can add a new checklist layout.
+% The \meta{begin} and \meta{end} part is similar to a
+% |\newenvironment|. The \meta{fields} must be a comma-separated list
+% of field names that can be the names of the checklist entry options
+% (plus ``description'' and ``status'') but can assume other values.
+%
+% \NiceDescribeMacro{\CheckListDefineFieldFormat}{\marg{layout}\marg{field}\marg{code}}
+% After the new type has been added, for each field in the
+% comma-separated \meta{fields}, this
+% macro must be used to define how a field is formatted. The
+% \meta{code} can take one argument, through which it is passed the
+% entry's option with name \meta{field}.
+%
+% \NiceDescribeMacro{\CheckListExtendLayout}{\marg{name}\marg{base}\marg{fields}}
+% Using this macro, you can extend an existing checklist layout.
+% Afterwards, the layout \meta{name} is available. This layout takes
+% the \meta{begin} and \meta{end} code from the \meta{base} layout.
+% Moreover, all fields defined by the \meta{base} layout can be used
+% in the \meta{fields} parameter of the new layout. However,
+% additional fields can be defined and the format of the fields for
+% the new layout can be overwritten via |\CheckListDefineFieldFormat|.
+% 
+% \section{Checklists and Other Packages}
+%
+% \subsection{asciilist}
+%
+% The \textsf{typed-checklist} package can be combined with the
+% \textsf{asciilist} package in the sense that a checklist can be
+% defined within an |AsciiList| environment. The
+% \textsf{typed-checklist} package provides a syntax for this when the
+% package is loaded with the |withAsciilist=true| option. The syntax
+% is illustrated with the following snippet, a transformed version of
+% the example in Section~\ref{sec:NestOptExample}:
+% \begin{LTXexample}[pos=t,preset=\FakeRefs]
+% \usepackage[withAsciilist=true]{typed-checklist}
+% \begin{AsciiList}[GoalList,TaskList]{-,*}
+%   - achieved[deadline=31.12.999]: No Y1K problems
+%   - open[who=John,deadline=31.12.1999]: No Y2K problems
+%     * started[who=John,label=Fix2]: Repair programs
+%     * open[who=Mankind,deadline=31.12.1999]:%
+%         Just turn off all computers, if \ref{Fix2} fails
+%   - unclear[deadline=31.12.9999]: No Y10K problems
+% \end{AsciiList}
+% \end{LTXexample}
+% For each checklist type \meta{type} (added by
+% |\CheckListAddType|), an |AsciiList| environment
+% \meta{type}|List| is automatically created.
+%
+% Note that currently, a checklist entry in an |AsciiList| environment
+% must fit into a single line \emph{or} each except for the last line
+% is ended with a percent char (as in the above example).
+% Note also that the |table| layout does not work within an |AsciiList|
+% environment.
+%
+% \section{Related Packages}
+%
+% The following \LaTeX{} packages provide related functionalities to
+% the \textsf{typed-checklist} package.
+%
+% \begin{description}
+% \item[\textsf{todo}:]
+%   The package allows for typesetting ``to-dos'', i.e., tasks in some
+%   sense, in a simple way with customizable display. The three main
+%   conceptual differences between \textsf{todo} and
+%   \textsf{typed-checklist} are:
+%   \begin{enumerate}
+%   \item \textsf{todo} does not distinguish between different types
+%     (such as goals and tasks);
+%   \item \textsf{todo} does not allow one to provide a status for a
+%     to-do and rather assumes that done to-dos are simply removed from
+%     the document;
+%   \item \textsf{todo} aims at specifying tasks for document into which
+%     the to-dos are placed, while \textsf{typed-checklist} aims at
+%     typesetting checklists whose entries are for more general kinds of
+%     projects.
+%   \end{enumerate}
+% \item[\textsf{easy-todo}:]
+%   The package is similar in spirit to the \textsf{tood} package and
+%   shares the main differences to the \textsf{typed-checklist} package.
+% \item[\textsf{todonotes}:]
+%   The package is similar in spirit to \textsf{todo} and
+%   \textsf{easy-tood}, but provide more formatting options for the
+%   to-dos.
+% \item[\textsf{pgfgantt}:]
+%   The package allows one to create Gantt charts, i.e., graphical
+%   displays of activities and milestones with a focus on time frames.
+%   The package allows one to structure the activities into groups. In
+%   that sense, there are certain similarities between the packages. The
+%   main conceptual difference to \textsf{typed-checklist} is the form
+%   of presentation (time-centric Gantt chart vs. text-centric lists).
+% \end{description}
+%
+% \section{Limitations and Future Work}
+%
+% \begin{itemize}
+% \item In |twoside| documents, deadlines are currently displayed in the
+%   left margin on even pages. The default layout (|list|) does not look
+%   good then. This should be repaired. The same problem is with
+%   checklist entry labels, which are displayed on the other side.
+% \item The package automatically adds the pre-defined checklist types
+%   and states, which might have two draws for some users: firstly, this
+%   adds a dependency on symbol packages, which might not work well
+%   together with some fonts; secondly, some users might prefer other
+%   definitions of the standard checklist types.
+%   To improve the situation, the package could offer an option for
+%   disabling the definition of the standard checklist types. Concerning
+%   the symbols packages, \textsf{typed-checklist} could also reduce the
+%   set of used packages or even draw all symbols itself.
+% \item The date format for deadlines currently is ``DD.MM.YYYY''. We
+%   could make the package more flexible in this regard by offering
+%   other formats as well, for instance by using the \textsf{datetime2}
+%   package.
+% \item The package displays checklist entries in the ordering in which
+%   they are listed in the \LaTeX{} sources. Automatic sorting of
+%   checklist entries, for instance by deadline or future fields like
+%   priority/importance, might make the package even more useful for
+%   bigger checklists.
+%   The implementation of the feature could be inspired by the following
+%   \textsf{stackexchange} thread:
+%   \url{http://tex.stackexchange.com/questions/6988/how-to-sort-an-alphanumeric-list}
+% \end{itemize}

+%
+% \subsection{Checklist Types}
+% In the following, we implement the existing types of checklists as
+% well as the macros for declaring new types.
+%
+% \begin{macro}{\tchklst@ChecklistTypes}
+% The |\tchklst@ChecklistTypes| collects the list of known checklist types.
+% Initially, the list is empty.
+%    \begin{macrocode}
+\newcommand*\tchklst@ChecklistTypes{}
+%    \end{macrocode}
+% \end{macro}
+% \begin{macro}{\CheckListAddType}
+% The |\CheckListAddType|\marg{type}\marg{symbol} adds a new
+% checklist type with name \meta{type} to the list of known
+% checklist types. The basic symbol of entries belonging to this
+% checklist type will be \meta{symbol} (e.g., an empty box or circle).
+%    \begin{macrocode}
+\newcommand*\CheckListAddType[2]{%
+%    \end{macrocode}
+% Add new type to existing list, if the type is not already known.

+% \end{macro}
+%
+% \begin{macro}{\tchklst@aux@OargAfter}
+% The |\tchklst@aux@OargAfter|\marg{macro-use}\oarg{opt-arg} macro takes a

+% added to the \meta{macro-use} in a way that the macro uses the
+% optional argument. If no optional argument is given, then the
+% \meta{macro-use} is taken as is.
+%
+% Example use: |\tchklst@aux@OargAfter{\cite{foo}}[page 9]| would expand
+% to |\tchklst@aux@OargAfter@ii{\cite}{page 9}{foo}| and, finally, to
+% |\cite[page 9]{foo}|.

+%
+% \subsection{Checklist Entry States}
+% In the following, we implement the existing status possibilities of
+% the individual checklist types as well as macros for declaring a new
+% status.
+%
+% \begin{macro}{\CheckListAddStatus}
+% The |\CheckListAddStatus|\marg{types}\marg{status}\marg{isclosed}\marg{symbol}
+% macro declares a new \meta{status} for a given comma-separated list of
+% checklist \meta{types}. The \meta{symbol} is \LaTeX{} code of a symbol
+% that is put on top of the checklist type's symbol. The \meta{isclosed}
+% parameter must be one of |true| or |false|. A value of |true|
+% indicates that the status of the entry corresponds to the entry being
+% closed. This particularly means that no warning will be shown if the
+% deadline of an entry with this status is passed. A value of |false|
+% for \meta{isclosed} indicates that the \meta{status} corresponds to
+% the entry not yet being closed.
+%    \begin{macrocode}
+\newcommand*\CheckListAddStatus[4]{%
+%    \end{macrocode}
+% We loop over all the checklist \meta{types} given.

+      {#1}}%
+%    \end{macrocode}
+% \begin{macro}{\tchklst@AddStatus}
+% The
+% |\tchklst@AddStatus|\marg{status}\marg{isclosed}\marg{symbol}\marg{type}
+% has the same parameters (in different ordering) and intention as
+% the |\CheckListAddStatus| macro, except that it assumes a single
+% \meta{type} instead of a type list. This macro is used internally by
+% |\CheckListAddStatus|.
+%    \begin{macrocode}

+%    \begin{macrocode}

+%    \end{macrocode}
+% The following line makes sure that the \textsf{bbding} font is
+% actually loaded, by simply putting a particular symbol into a box and
+% then forgetting the box again (via the grouping). This addresses the
+% case that the \textsf{bbding} symbols are used inside an |\import*| or
+% |\subimport*| of the \textsf{import} package: In this case, the font
+% would be attempted to be loaded only inside the `import' and could
+% then no longer be found (producing ``No file Uding.fd'').
+%    \begin{macrocode}
+\AtBeginDocument{{\setbox0\hbox{\Checkmark}}}
+%    \end{macrocode}
+% The following provides the default set of checklist types.

+%
+% \subsection{Default Checklist Layouts}
+%
+% The following provides the default set of checklist layouts.
+%
+% \subsubsection{list}
+%
+% We use the \textsf{marginnote} package to display deadlines in the |list|
+% layout.
+%    \begin{macrocode}
+\RequirePackage{marginnote}
+%    \end{macrocode}
+%
+% The |list| layout is based on a |description| environment with a
+% slightly modified vertical and horizontal spacing.
+% \changes{v1.1b}{2015/03/05}{Fix for more comprehensible error messages
+%   when end of environment is forgotten}
+% \changes{v1.3b}{2015/07/26}{Removed dependency on \textsf{paralist}
+%   package}
+%    \begin{macrocode}
+\CheckListDeclareLayout{list}{status,label,description,who,deadline,END}%
+  {\bgroup\topsep=\medskipamount\itemsep=0pt\description
+    \advance\itemindent by 0.5em}%
+  {\enddescription\egroup}
+%    \end{macrocode}
+% The checklist entry starts with the status symbol, which opens up a
+% new list item.
+%    \begin{macrocode}
+\CheckListDefineFieldFormat{list}{status}%
+  {\item[{\normalfont\tchklst@getsymbol{#1}}]}
+%    \end{macrocode}
+% Show the label in the reverse margin, with some nice layout.
+% \changes{v1.4}{2016/03/30}{Robustified label display in inner mode}
+%    \begin{macrocode}
+\CheckListDefineFieldFormat{list}{label}{%
+  \ifstrempty{#1}{}{\ifbool{inner}%
+      {{\small(\ref{#1}) }}%
+      {\leavevmode\reversemarginpar\marginpar{%
+       \textcolor{gray}{\underbar{\hbox to \hsize{%
+       \normalfont\textcolor{black}{\ref{#1}}\hfil}}}}}}}
+%    \end{macrocode}
+% Show the description, with leading spaces removed.
+%    \begin{macrocode}
+\CheckListDefineFieldFormat{list}{description}{%
+    \ignorespaces #1\relax}
+%    \end{macrocode}
+% Show the responsible person(s), if the |who| option is given in
+% \meta{options}.
+%    \begin{macrocode}
+\CheckListDefineFieldFormat{list}{who}{%
+  \ifstrempty{#1}{\hfill\null}{%
+    \tchklst@signed{\textit{(#1)}}}}
+%    \end{macrocode}
+% Show the deadline of the entry in the margin, if the |deadline| option
+% is given in \meta{options}.
+% \textbf{FIXME:} here, the interface of the code is not very elegant,
+% because the field format code uses the internal macro
+% |\cmdtchklst@EntryOption@status| for obtaining the current entry's
+% status.
+%    \begin{macrocode}
+\CheckListDefineFieldFormat{list}{deadline}{%
+  \ifstrempty{#1}{}{{\normalmarginpar\marginnote{%
+     \tchklst@DisplayDeadline{\cmdtchklst@EntryOption@status}{#1}}}}}
+%    \end{macrocode}
+% End the display of one checklist entry.
+% \meta{options}.
+%    \begin{macrocode}
+\CheckListDefineFieldFormat{list}{END}{{%
+  \parfillskip=0pt \finalhyphendemerits=0 \endgraf}}
+%    \end{macrocode}
+%
+% \begin{macro}{\tchklst@DisplayDeadline}
+% The |\tchklst@DisplayDeadline|\marg{status}\marg{deadline} formats a
+% \meta{deadline} dependent on the \meta{status} and the current date.
+%    \begin{macrocode}
+\newcommand\tchklst@DisplayDeadline[2]{%
+%    \end{macrocode}
+% Check which text color to use for this item if its deadline has
+% already passed.
+%    \begin{macrocode}
+  \tchklst@ifsymdone{\tchklst@cur@type}{#1}%
+    {\def\tchklst@deadcolor{green!66!black}}%
+    {\def\tchklst@deadcolor{red}}%
+%    \end{macrocode}
+% Check whether the deadline of the entry has already passed and, if so,
+% set the text color to the color determined above.
+%    \begin{macrocode}
+  \tchklst@ifafterdots#2\relax%
+    {\textcolor{\tchklst@deadcolor}}%
+    {}%
+%    \end{macrocode}
+% Show the actual deadline. Note that this may constitute the second
+% parameter of the above |\textcolor|.
+%    \begin{macrocode}
+    {#2}}
+%    \end{macrocode}
+% \end{macro}
+%
+% \subsubsection{hidden}
+%
+% The |hidden| layout completely hides the checklist and all its
+% entries. We add the |status| field only to ignore spaces after each
+% entry.
+%    \begin{macrocode}
+\CheckListDeclareLayout{hidden}{dummy}{\ignorespaces}{\ignorespaces}
+\CheckListDefineFieldFormat{hidden}{dummy}{\ignorespaces}
+%    \end{macrocode}
+%
+% \subsubsection{table}
+%
+% The |table| layout formats the checklist as a table, one row per
+% checklist entry. The |NC| field just inserts the column separator.
+% \changes{v1.4}{2016/03/30}{Added display of labels to table layout}
+%    \begin{macrocode}
+\RequirePackage{longtable,tabu}
+\CheckListDeclareLayout{table}%
+  {status,NC,label,description,NC,who,NC,deadline,endline}%
+  {%
+    \tabulinesep=0.5ex
+    \longtabu to \linewidth {|c|X|r|r|}
+    \hline
+    \bf Status & \bf Description & \bf Who & \bf Deadline\endhead\hline}
+  {\endlongtabu}
+\CheckListDefineFieldFormat{table}{status}{\tchklst@getsymbol{#1}}
+\CheckListDefineFieldFormat{table}{label}%
+  {\ifstrempty{#1}{}{{\small(\ref{#1}) }}}
+\CheckListDefineFieldFormat{table}{description}{\ignorespaces #1}
+\CheckListDefineFieldFormat{table}{deadline}{#1}
+\CheckListDefineFieldFormat{table}{who}{#1}
+\CheckListDefineFieldFormat{table}{NC}{&}
+\CheckListDefineFieldFormat{table}{endline}{\\\hline}
+%    \end{macrocode}
+%
+% \subsection{Compatibility with Other Packages}
+%
+% \subsubsection{asciilist}
+%
+% \begin{macro}{\tchklst@ChkListEntry}
+% The |\tchklst@ChkListEntry|\marg{item-macro}\marg{content} macro can be
+% used as a parameter to |\AsciiListEndArg| of the
+% \textsf{asciilist} package in order to allow for checklist
+% entries in an |AsciiList|.
+%    \begin{macrocode}
+\iftchklst@withAsciilist
+\newcommand*\tchklst@ChkListEntry[2]{%
+	\tchklst@ChkListEntry@i{#1}#2\@undefined}
+%    \end{macrocode}
+% The used auxiliary macros serve the purpose of parsing the input and
+% have the following signatures:
+% \begin{itemize}
+% \item
+%   |\tchklst@CheckListEntry@i|\marg{item-macro}\marg{status+opts}\marg{entry}
+%   where \meta{entry} is the goal/task/... of the checklist entry.
+% \item
+%   |\tchklst@CheckListEntry@ii|\marg{item-macro}\marg{entry}\marg{status}\marg{options}.
+% \end{itemize}
