+The LaTeX dtxdescribe package
+Describe additional object types in dtx source files.
+
+v0.10 — 2016/12/08
+Copyright 2016 Brian Dunn — www.BDTechConcepts.com
+LaTeX Project Public License, version 1.3
+
+The doc package includes tools for describing macros and environments in
+LATEX source dtx format. The dtxdescribe package adds additional tools for
+describing booleans, lengths, counters, keys, packages, classes, options, files,
+commands, arguments, and other objects.
+
+Each item is given a margin tag similar to \DescribeEnv, and is listed in
+the index by itself and also by category. Each item may be sorted further by
+an optional class. All index entries except code lines are hyperlinked.
+
+Descriptions are best accompanied by examples, so the environment
+dtxexample is provided. Contents are displayed verbatim along with a
+caption and cross-referencing. They are then \input and executed, and the
+result is shown.

+% \section{Introduction}
+%
+% The \pkg{doc} package provides \cs{DescribeMacro} and \cs{DescribeEnv}
+% to help document new macros and environments.
+% Each generates a heading in the documentation, to which \cs{marg},
+% \cs{oarg}, and \cs{parg} may be added to identify arguments to be
+% passed to the new object.
+% Their names are added to the margin, and index entries are added,
+% as well as group of entries for environments.
+%
+% \pkg{dtxdescribe} extends this concept to include a number of
+% additional objects, such as booleans and keys.
+% To help identify what is being described in the margin, small tags
+% added to the name, such as ``Env'', ``Bool'', or ``Key''.
+% These new objects are also listed in the index with the same tag
+% shown after their names, and also by group.
+% Optional classes may be used to further categories index entries.
+%
+% Modifications have been made to interact with \pkg{hyperref} to
+% provide hyper links for regular index entries as well as the new
+% \cs{Describe} entries.
+%
+% Additional macros are provided to generate colored margin tags and
+% warnings, and a new |dtxexample| environment demonstrates code examples.
+%
+% This documentation and its index show examples of these macros in use.
+%
+% While the index may appear to be overkill for a small package,
+% \margintag{Too much!}
+% keep in mind that it includes a number of fictional entries from the examples.
+% Extensive cross-referencing can be useful for larger works.
+% And, of course, you need not cross-reference everything!
+
+
+% \clearpage
+% \section{Using \pkg{dtxdescribe}}
+
+% Place |\usepackage{dtxdescribe}| in the |.dtx| file's driver section:
+% \begin{verbatim}
+% %<*driver>
+% \documentclass{ltxdoc}
+% ...
+% \usepackage{lmodern}
+% ...
+% \usepackage{dtxdescribe}
+% ...
+% \usepackage{packagename} % the name of your new package
+% ...
+% \usepackage[...]{hyperref}
+% \usepackage{...]{cleveref}
+% ...
+% %</driver>
+% \end{verbatim}
+
+% Various objects inside the |dtx| file may be described with \cs{DescribeBoolean},
+% \cs{DescribeLength}, \cs{DescribeCounter}, and related macros,
+% similar to the already-familiar \cs{DescribeMacro} and \cs{DescribeEnv}.
+
+% Optional ``classes'' may be assigned to the objects being described, including the new verisons
+% of \cs{DescribeMacro} and \cs{DescribeEnv}.
+% These classes are printed in the margin tag and index entry for each item,
+% and also generate additional index entries sorted by class. This is
+% especially useful for key/value sets, where several sets may appear in the same
+% document.
+%
+% The margin tag is not printed if
+% \margintag{inside a float}
+% the \cs{Describe} macros are used inside a float such as a table,
+% but the index entries are still made.
+%
+% |\margintag{text}| may be used to place a colored tag in
+% \margintag{\cs{margintag} text}
+% the margin to summarize paragraph
+% contents or draw attention to an index destination.
+%
+% |\watchout[optional text]| may be used to place a red warning sign
+% \watchout[\cs{watchout} text]
+% in the margin, along with optional text.
+%
+% The \env{dtxexample} environment may be used to typeset and execute small pieces of \LaTeX\ code
+% as examples of its use. Optional cross-referencing notes may be used to refer to any
+% example float being generated.
+
+
+
+% \clearpage
+% \section{The Macros, and the \env{dtxexample} Environment}
+
+
+
+% \subsection{Pre-existing Macros}
+%
+% \DescribeMacro{\DescribeMacro} \oarg{class} \marg{\cs{name}}
+%
+% The pre-existing macro from the \pkg{doc} is redefined to
+% allow hyperlinked index entries and an optional class.
+% A margin tag is created and an index entry is made.
+% When the optional class is used, it is displayed in front of
+% the margin tag, and is used to group an index entry by
+% macro name and another index entry by class.
+% An example would be to describe
+% the float creation and caption setup for a new class of float,
+% such as the |dtxexample| float and the example ``photograph'' float
+% both found in the index for this document.
+% See \cref{ex:macro} on \cpageref{ex:macro} for examples.
+%
+% \DescribeMacro{\DescribeEnv} \oarg{class} \marg{environment name}
+%
+% The pre-existing macro from the \pkg{doc} is redefined to
+% allow hyperlinked index entries, and also to place
+% an `Env' tag in front of the name in the margin.
+% See \cref{ex:environment} on \cpageref{ex:environment}.
+%
+
+
+% \subsection{Macro Arguments}
+%
+% The \cs{Describe}\rule{.25in}{.4pt} macros
+% may be followed by \cs{marg}, \cs{oarg}, and \cs{parg} to
+% describe arguments passed to the macros.
+%
+% \DescribeMacro{\marg} \marg{text}
+%
+% Shows a mandatory argument for a macro or environment.
+%
+% The results looks like \marg{mandatory}.
+%
+
+% \DescribeMacro{\oarg} \marg{text}
+%
+% Shows an optional argument for a macro or environment.
+%
+% The results looks like \oarg{optional}.
+%
+
+% \DescribeMacro{\parg} \marg{text}
+%
+% Used for ``picture'' arguments, such as coordinates.
+%
+% The result looks like \parg{coordinate}.
+%
+
+% \DescribeMacro{\DescribeArgument} \oarg{class} \marg{argument}
+%
+% May be used to describe actions taken when given certain macro arguments.
+% These will be given an `Arg' margin tag and will appear in the index.
+% The |class| may be used to categorize arguments by their macro or environment name.
+% See \cref{ex:arguments} on \cpageref{ex:arguments}.
+
+
+% \subsection{Common \LaTeX\ Elements}
+%
+% See \cref{ex:common} on \cpageref{ex:common}.
+%
+% \DescribeMacro{\DescribeBoolean} \oarg{class} \marg{name}
+%
+% Describes a boolean. Given a `Bool' tag in the margin and index.
+%
+%
+% \DescribeMacro{\DescribeLength} \oarg{class} \marg{name}
+%
+% Describes a length. Given a `Len' tag in the margin and index.
+%
+%
+% \DescribeMacro{\DescribeCounter} \oarg{class} \marg{name}
+%
+% Describes a counter. Given a `Ctr' tag in the margin and index.
+%
+%
+% \DescribeMacro{\DescribeKey} \oarg{class} \marg{name}
+%
+% Describes a key. Given a `Key' tag in the margin and index.
+% The |class| may be used to categorize keys by their kev/value group.
+% See \cref{ex:key} on \cpageref{ex:key}.
+
+
+% \subsection{References to External Packages and Classes}
+%
+% \DescribeMacro{\DescribePackage} \oarg{class} \marg{name}
+%
+% Describes a package. Given a `Pkg' tag in the margin and index.
+%
+%
+% \DescribeMacro{\DescribeClass} \oarg{class} \marg{name}
+%
+% Describes a \LaTeX\ class. Given a `Cls' tag in the margin and index.
+%
+%
+% \DescribeMacro{\DescribeOption} \oarg{class} \marg{name}
+%
+% Describes a \LaTeX\ package or class option. Given an `Opt' tag in the margin and index.
+%
+%
+
+% \subsection{Files, Programs, and Commands}
+%
+% \DescribeMacro{\DescribeFile} \oarg{class} \marg{name}
+%
+% Describes an operating-system file. Given a `File' tag in the margin and index.
+% The filename may have underscores.
+%
+%
+% \DescribeMacro{\DescribeProgram} \oarg{class} \marg{name}
+%
+% Describes an operating-system program. Given a `Prog' tag in the margin and index.
+% The program name may have underscores.
+%
+%
+% \DescribeMacro{\DescribeCommand} \oarg{class} \marg{name}
+%
+% Describes an operating-system command. Given a `Cmd' tag in the margin and index.
+% The command name may have underscores.
+%
+%
+
+
+% \subsection{Other Source Objects}
+%
+% \DescribeMacro{\DescribeObject} \oarg{class} \marg{name}
+%
+% Describes an arbitrary programming object, such as a color definition or caption setup.
+% A margin tag and index entry are created with \cs{ttfamily} type.
+% When a class is used, it is pre-pended to the margin tag, appended to the
+% index entry, and a second index entry is created grouped by class.
+% If a macro name is to be described, use \cs{DescribeMacro} instead.
+% See \cref{ex:object} on \cpageref{ex:object}.
+%
+%
+% \DescribeMacro{\DescribeOther} \oarg{class} \marg{name}
+%
+% Describes an arbitrary non-programming object, such as a license agreement
+% or credits. A margin tag and index entry are created in roman type.
+% When a class is used, it is pre-pended to the margin tag, appended to the
+% index entry, and a second index entry is created grouped by class.
+% See \cref{ex:other} on \cpageref{ex:other}.
+
+
+% \subsection{Additional Tags}
+%
+%
+% \DescribeMacro{\margintag} \marg{text}
+%
+% Creates a colored margin tag.
+% May be used to identify the topic of a paragraph or the destination of
+% an arbitrary index entry.
+
+%
+% \DescribeMacro{\watchout} \oarg{text}
+%
+% Creates a red margin tag with a warning sign and
+% optional text. May be used to warn the reader of special instructions, etc.
+
+
+% \subsection{\env{dtxexample} Environment}
+%
+% \DescribeEnv{dtxexample} * \oarg{Notes/cross-references} \marg{caption \& label}
+%
+% The \env{dtxexample} environment is useful for demonstrating a piece of \LaTeX\ code.
+% The example is a simulated float with its own caption and optional label,
+% along with optional notes and/or cross-referencing commands.
+% The contents of the \env{dtxexample} environment are printed verbatim, then
+% loaded and executed as \LaTeX\ code, showing the results just below the printed code.
+% In the case of float commands, the floats are generated as expected somewhere nearby,
+% and should be given their own labels.
+% References to the float's labels may be placed in the optional argument to
+% the \env{dtxexample} environment, and will be printed below the code.
+%
+%
+% The unstarred version places the code inside a
+% minipage, forbidding a page break in the middle of the code listing. The starred
+% version does not use a minipage. This is required when the code is too large to fit
+% on a single page.
+%
+% See \cref{ex:dtxexample} for a demonstration of how \env{dtxexample} works.
+
+
+
+% \clearpage
+%
+% \section{Examples}
+
+
+% \begin{dtxexample}{Macros\label{ex:macro}}
+% \DescribeMacro{\mymacro} \oarg{optional} \marg{mandatory}

+% See this document's index entries for examples of this ``photograph''
+% class and the \env{dtxexample} class of macros.
+%
+% The re-defined \cs{DescribeMacro}, \cs{DescribeEnv}, and

+% \section{Usage Notes}
+%
+% \begin{description}
+%
+% \item[Placement of \cs{Describe} macros:]
+% Typically \LaTeX\ macro and environment definitions are enclosed in
+% \env{macro} and \env{environment} environments at their place in the source code.
+% \cs{DescribeMacro} and \cs{DescribeEnv} would be used elsewhere in the manual
+% to describe how to use the code. \cs{DescribeBoolean} and such might be at
+% their place in the source code, unless they are worthy of discussion for the
+% end-user, in which case they should be in the ``User's Manual'' section of the
+% document.\footnote{Future versions may include \cs{DeclareBoolean} for
+% use at the point where the boolean is defined, creating an index entry
+% with a code line number, and \cs{DescribeBoolean} with a page number index entry for
+% the related discussion in the User's Manual portion of the document.}
+% It may be useful to use \cs{DeclareBoolean} and friends both at the code location
+% and also in the User's Manual section.
+%
+% \item[Extra spaces:] When placing multiple \cs{Describe}, \cs{index}, \cs{margintag}, and
+% \cs{watchout} macros
+% together, care must be taken to avoid extra space in the printed text where
+% these macros occur. Try to place the first one directly connected to a word,
+% and the others may follow on the next line if necessary.
+% \begin{verbatim}
+% text text text\margintag{A comment.}\index{An entry}
+% \index{Another entry}
+% more inline text text text
+% \end{verbatim}
+%
+% \item[\cs{margintag} placement:] To have the margin tag appear next to the first
+% line of a paragraph, place the \cs{margintag} or \cs{watchout}
+% somewhere after the first few words
+% in the paragraph. The \cs{margintag} may be on its own line,
+% and the rest of the paragraph may follow on the next line.
+% If too many words are printed before the \cs{margintag},
+% the words may wrap to the next line before the tag occurs.
+%
+% \item[Margin tag overlap:] To keep margin tags in proper alignment,
+% use a new paragraph or multiple lines
+% between \cs{margintag}, \cs{watchout}, or \cs{Declare} macros
+%
+% \item[\cs{Describe} inside floats:] When these macros are used inside a float,
+% \margintag{missing tags}\index{margin tag missing}
+% the margin tag is supressed (there is no margin in a float), but the
+% index entries are still created.

+% Creates the index entries for the object being described, where

+% \begin{macrocode}
+\newcommand*{\DTXD at index}[5]{%
+% \end{macrocode}
+% The |makeindex| program allows each index entry to call a macro by appending
+% a vertical bar and a macro name to each entry.
+% \pkg{hyperref} adds a call by \cs{hyperpage} to each index entry, by appending
+% the phrase \verb+|hyperpage+ to the entry in the |.idx| file.
+% The \pkg{doc} package uses the same mechanism to
+% distinguish between code line entries (\verb+|main+) and
+% references to the use of a macro (\verb+|usage+). The problem is that |makeindex|
+% can only handle one macro call, but \pkg{hyperref} tries to append its \verb+|hyperpage+
+% to the already-existing \verb+|usage+ or \verb+|main+.
+%
+% The solution used for \pkg{dtxdescribe} is to allow \pkg{hyperref} to modify all
+% regular index entries, but use the original definition of \cs{@wrindex}
+% for the \cs{Describe}\rule{.25in}{.4pt} macros, before \pkg{hyperref} modified it.
+% Then, the \cs{usage} macro, defined above, manually adds the hyperlink.
+%
+% Below, \cs{@bsphack} and \cs{@esphack} seem to be required for \cs{@wrindex} to work.
