% \begin{abstract}
% \noindent Using the \textsf{nameauth} package, an author can encode names according to a name authority. Index entries will be consistent if the input parameters are consistent. An author can move blocks of text arbitrarily and the names will be reformatted automatically, making it easier to transition from drafts to a final manuscript. This package mainly supports Western naming conventions, with some basic features for ancient, royal, and Eastern names.
% \end{abstract}
%
% \section{Introduction}
%
% Suppose you were working on a collection of essays. Different publishers' permissions may force you to accept variance in the spelling of people's names. You would track and index those names using a name authority. Your index might use abbreviated name forms. This package allows the author to encode names so that the time and cost of an editor and proofreader can be minimized. This could make an author more desirable for publication.
%
% \subsection{Typesetting, Indexing, and Design}
%
% This package depends on \textsf{etoolbox} and \textsf{xparse.} It has been tested with \textsf{latex}, \textsf{lualatex}, \textsf{pdflatex} and \textsf{xelatex}, as well as \textsf{makeindex} and \textsf{texindy}. This file was typeset with \ifxetex\textsf{xelatex}\else\ifluatex\ifpdf\textsf{lualatex} in \texttt{pdf} mode\else\textsf{lualatex} in \texttt{dvi} mode\fi\else\ifpdf\textsf{pdflatex}\else\textsf{latex}\fi\fi\fi{} and \textsf{makeindex}. The default options and design of this package try to minimize keystrokes or trade extra work for benefits in formatting and consistency. The \texttt{.dtx} file is also a good source of information.
%
% \subsection{Thanks}
%
% Thanks to \Name[Marc van]{Dongen}, \Name[Enrico]{Gregorio}, \Name[Philipp]{Stephani}, \Name[Heiko]{Oberdiek}, \Name[Uwe]{Lueck}, and \Name[Robert]{Schlicht} for their invaluable assistance. \FName[Marc van]{Dongen}[Marc] showed me the basic structure using the \textsf{xparse} package. \FName[Enrico]{Gregorio} and \FName[Philipp]{Stephani} helped with generating control sequences and sanitizing. \FName[Heiko]{Oberdiek} gave a space-removing solution that could be passed as an argument in a macro. Code adapted from \FName[Uwe]{Lueck}'s work on the texhax list and the sagacious advice of \FName[Robert]{Schlicht}  enabled the routines to function with the \textsf{microtype} package.
%
% \section{Usage}
%
% \subsection{Package Options}
% If the default behavior is not desired, the following options easily alter it. The class options are listed with defaults first in each category:
%
% \begin{quote}\small
% \begin{tabular}{lp{3in}}
% \texttt{mainmatter} & The default behavior triggers special typesetting of the first occurrence of a name, starting at the beginning of a document.\\[1ex]
% \texttt{frontmatter} & This option suppresses the special typesetting of the first occurrence of a name before the invocation of \cmd{\NamesActive}. This option fits well with front matter from a contributor who may not intend the same formatting and emphasis found in the main matter. The indexing and aliasing features of the package remain operative. \emph{Note}: One can switch at will between formatted and non-formatted sections; see Section \ref{sec:SectionFormat}.\\[0.25ex]\hline
% {\large\strut}\texttt{smallcaps} & The default behavior when a name is first encountered is to print it in small caps.\\[1ex]
% \texttt{italic} & This option causes the first occurrence of the name to be italicized.\\[1ex]
% \texttt{boldface} & This option causes the first occurrence of the name to be set in boldface.\\[1ex]
% \texttt{noformat} & This option suppresses document formatting after the invocation of \cmd{\NamesActive} if an author wants the indexing and aliasing functions without any special typesetting. Additional formatting options are discussed in Section \ref{sec:formatting}. This option is \emph{not} equivalent to \texttt{frontmatter}, which prevents formatting when in force. The \texttt{noformat} option simply sets the ``formatting'' to nil, helping one to write the same document for different publishers' style requirements.\\[0.25ex]\hline
% {\large\strut}\texttt{nocomma} & The default behavior suppresses printing of commas between surnames and suffixes, following modern styles like \emph{Chicago Manual of Style}. See Section \ref{sec:suffix} for additional implications of this behavior.\\[1ex]
% \texttt{comma} & Print commas between surnames and suffixes, following older styles. Several points throughout the document discuss the limits that this option imposes.\\[0.25ex]\hline
% {\large\strut}\texttt{index} & The default behavior creates index entries in place with the names.\\[1ex]
% \texttt{noindex} & Similar to \texttt{frontmatter}, this option prevents indexing until a call to \cmd{\IndexActive}. See also Section \ref{sec:SectionIndex}.\\

% \subsection{Example Text}
% \label{sec:example}
%
% We begin with a sample text that attempts to cover the basic features, and even a couple of advanced ones. It is in the genre of a merry wedding reception toast, proving that a serious package can be used lightheartedly.\\
%
% \noindent DISCLAIMER: I use a number of names associated with historical figures throughout this document. This is because I expect that the users of this package will refer to real-world figures. At no time in this document am I intending either to promote, disparage, align with, align against, or make any assertions about any persons living or dead. As far as I am concerned, all names mentioned herein deserve respect for the impact and legacy of their bearers.\\
%
% \noindent\textbf{Example Text:}
%
% {\small\ttfamily This is a toast to |\Name[John]{Smith}| and his longtime sweetheart,\newline |\Name[J.Q.]{Public}[Jane Q.]|. |\FName[John]{Smith}| and\break |``\FName[J.Q.]{Public}[Janie]''| have finally made it official today! After\break casual dating as teenagers, they met again in college where they learned\break about |\Name{Aristotle}| and all the stuff that I can't keep in my head.\break [laughs] Nevertheless, by the time they got to |\Name{John}[Duns Scotus]| they were definitely a number.

%  
% This is a toast to \Name[John]{Smith} and his longtime sweetheart, \Name[J.Q.]{Public}[Jane Q.]. \FName[John]{Smith} and ``\FName[J.Q.]{Public}[Janie]'' have finally made it official today! After casual dating as teenagers, they met again in college where they learned about \Name{Aristotle} and all the stuff that I can't keep in my head. [laughs] Nevertheless, by the time they got to \Name{John}[Duns Scotus] they were definitely a number. They studied medieval history-makers like \Name{Gregory, I} ``\AKA*{Gregory, I}{Gregory}[the Great]'' and by the Renaissance they were engaged. After spending time in separate grad schools, these promising medievalists got faculty positions at adjoining colleges and here we are. As the brother of \FName[J.Q.]{Public}[Jane] ``\AKA*[J.Q.]{Public}{Jane}[the Great]'' I am happy to welcome \FName[John]{Smith}[Sir John] to our raucous family.\\
%  
% Here you will notice that one can make a reference to Pope |\Name{Gregory, I}| followed by ``the Great'' via |``\AKA*{Gregory, I}{Gregory}[the Great]''|. That is achieved by the ambiguous behavior of the default \texttt{nocomma} option plus the ``sobriquet only'' feature of \cmd{\AKA*}. It is easy to use these features, but can be tricky to debug. Sections \ref{sec:suffix} and \ref{sec:pennames} have more details.

% \subsection{Quick Start Guide}
% \label{sec:start}
% \changes{v0.8}{2012/01/29}{Added quick start guide}
% \changes{v0.85}{2012/02/05}{Updated quick start guide}
% \changes{v0.96}{2012/02/19}{Redesigned guide for better readability.}
%
% This ``cheat sheet'' engages about 80\% of the features in this package.
%
% \begin{multicols}{2}\small
% \subsubsection{Rules of Thumb}
% \begin{enumerate}\setlength\itemsep{0pt}\small
% \item \cmd{\frenchspacing} is recommended.
% \item The indexed forms of the names remain the same if you follow the macro input charts consistently.
% \item Problematic index entries often lead to correctable mistakes.
% \item Trade work for consistency.
% \item Use just the macros you \emph{need}.
% \end{enumerate}
% \subsubsection{Basic}
% These examples work predictably under the broadest conditions.
% \begin{enumerate}\setlength\itemsep{0pt}\small
% \item First reference: \ForgetName[John]{Smith}\Name[John]{Smith}\\[0.5ex]
% |\Name*[John]{Smith}| or\\ |\Name[John]{Smith}| or\\ |\FName[John]{Smith}|
% \item Subsequent full name: \Name*[John]{Smith}\\[0.5ex]
% |\Name*[John]{Smith}|
% \item Subsequent surname: \Name[John]{Smith}\\[0.5ex]
% |\Name[John]{Smith}|
% \item Subsequent forename: \FName[John]{Smith}\\[0.5ex]
% |\FName[John]{Smith}|
% \item First mononym reference: \ForgetName{Plato}\Name{Plato}\\[0.5ex]
% |\Name*{Plato}| or\\ |\Name{Plato}| or\\ |\FName{Plato}|
% \item Subsequent references: \Name{Plato}\\[0.5ex]
% |\Name*{Plato}| or\\ |\Name{Plato}| or\\ |\FName{Plato}|\\[1.5ex]
% These next examples work with the \texttt{comma} option, not \cmd{\AKA} and \cmd{\PName}. The next page offers a workaround that depends on the \texttt{nocomma} option.
% \item First Eastern ref: \ForgetName{Mao}[Tse-tung]\Name{Mao}[Tse-tung]\\[0.5ex]
% |\Name*{Mao}[Tse-tung]| or\\ |\Name{Mao}[Tse-tung]|
% \item Subsequent references: \Name*{Mao}[Tse-tung]\\[0.5ex]
% |\Name*{Mao}[Tse-tung]|
% \item Subsequent references: \Name{Mao}[Tse-tung]\\[0.5ex]
% |\Name{Mao}[Tse-tung]| or\\ |\FName{Mao}[Tse-tung]|
% \item First royal: \ForgetName{Louis}[the Pious]\Name{Louis}[the Pious]\\[0.5ex]
% |\Name*{Louis}[the Pious]| or\\ |\Name{Louis}[the Pious]| or\\ |\FName{Louis}[the Pious]|
% \item Subsequent refs: \Name*{Louis}[the Pious]\\[0.5ex]
% |\Name*{Louis}[the Pious]|
% \item Subsequent references: \Name{Louis}[the Pious]\\[0.5ex]
% |\Name{Louis}[the Pious]| or\\ |\FName{Louis}[the Pious]|
% \item First ancient: \ForgetName{Ptolemy I}[Soter]\Name{Ptolemy I}[Soter]\\[0.5ex]
% |\Name*{Ptolemy I}[Soter]| or\\ |\Name{Ptolemy I}[Soter]| or\\ |\FName{Ptolemy I}[Soter]|

% \item Subsequent refs: \Name{Ptolemy I}[Soter]\\[0.5ex]
% |\Name{Ptolemy I}[Soter]| or\\ |\FName{Ptolemy I}[Soter]|
% \item First royal: \ForgetName{Henry}[VIII]\Name{Henry}[VIII]\\[0.5ex]
% |\Name*{Henry}[VIII]| or\\ |\Name{Henry}[VIII]| or\\ |\FName{Henry}[VIII]|
% \item Subsequent refs: \Name*{Henry}[VIII]\\[0.5ex]
% |\Name*{Henry}[VIII]|
% \item Subsequent references: \Name{Henry}[VIII]\\[0.5ex]
% |\Name{Henry}[VIII]| or\\ |\FName{Henry}[VIII]|\\[1ex]
% \end{enumerate}
% \subsubsection{Intermediate}
% The following employ alternate forenames. They keep regular forenames in the index. 
% \begin{enumerate}\setlength\itemsep{0pt}\small
% \item Print an embellished first reference: \ForgetName[J.Q.]{Public}\Name[J.Q.]{Public}[Jane Q.]\\[0.5ex]
% |\Name*[J.Q.]{Public}[Jane Q.]| or\\ |\Name[J.Q.]{Public}[Jane Q.]| or\\ |\FName[J.Q.]{Public}[Jane Q.]|
% \item Subsequent full name, alternate forename, same person in index: \Name*[J.Q.]{Public}[Jane Qetsiyah]\\[0.5ex]
% {\footnotesize |\Name*[J.Q.]{Public}[Jane Qetsiyah]|}
% \item Subsequent ``shorter'' full name, same person in index: \Name*[J.Q.]{Public}\\[0.5ex]
% |\Name*[J.Q.]{Public}|
% \item Subsequent alternate forename, same person in index: \FName[J.Q.]{Public}[Janie]\\[0.5ex]
% |\FName[J.Q.]{Public}[Janie]|
% \end{enumerate}
% \subsubsection{Advanced}
% These next examples engage a number of special cases. Many depend on the default \texttt{nocomma} option. Always use a comma to delimit suffixes. Use a space or thin space after the comma. These forms will work with \cmd{\AKA} and \cmd{\PName}. See also Section \ref{sec:suffix}
% \begin{enumerate}\setlength\itemsep{0pt}\small
% \item First: \ForgetName[George S.]{Patton, Jr.}\Name[George S.]{Patton, Jr.}\\[0.5ex]
% {\footnotesize |\Name*[George S.]{Patton, Jr.}| or\\ |\Name[George S.]{Patton, Jr.}| or\\ |\FName[George S.]{Patton, Jr.}|}
% \item Subsequent full: \Name*[George S.]{Patton, Jr.}\\[0.5ex]
% |\Name*[George S.]{Patton, Jr.}|
% \item Subsequent surname: \Name[George S.]{Patton, Jr.}\\[0.5ex]
% |\Name[George S.]{Patton, Jr.}|
% \item Subsequent forename: \FName[George S.]{Patton, Jr.}[George]\\[0.5ex]
% |\FName[George S.]{Patton, Jr.}%|\\|[George]|\\[2ex] The next forms take advantage of comma suppression to implement forms of ancient, royal and Eastern names. Adding a final optional parameter is discouraged.
% \item First reference: \ForgetName{Gregory, I}\Name{Gregory, I}\\[0.5ex]
% |\Name*{Gregory, I}| or\\ |\Name{Gregory, I}| or\\ |\FName{Gregory, I}|
% \item Subsequent full name: \Name*{Gregory, I}\\[0.5ex]

% \item First reference: \ForgetName{Demetrius, I Soter}\Name{Demetrius, I Soter}\\[0.5ex]
% |\Name*{Demetrius, I Soter}| or\\ |\Name{Demetrius, I Soter}| or\\ |\FName{Demetrius, I Soter}|
% \item Next full name: \Name*{Demetrius, I Soter}\\[0.5ex]
% |\Name*{Demetrius, I Soter}|
% \item Subsequent name: \Name{Demetrius, I Soter}\\[0.5ex]
% |\Name{Demetrius, I Soter}| or\\ |\FName{Demetrius, I Soter}|
% \item First reference: \ForgetName{Sun, Yat-sen}\Name{Sun, Yat-sen}\\[0.5ex]
% |\Name*{Sun, Yat-sen}| or\\ |\Name{Sun, Yat-sen}| or\\ |\FName{Sun, Yat-sen}|
% \item Subsequent full name: \Name*{Sun, Yat-sen}\\[0.5ex]
% |\Name*{Sun, Yat-sen}|
% \item Subsequent name: \Name{Sun, Yat-sen}\\[0.5ex]
% |\Name{Sun, Yat-sen}| or\\ |\FName{Sun, Yat-sen}|\\[2ex] The following illustrate the American style of particulate names.
% \item First: \Name[Walter]{de la Mare}\\[0.5ex]
% |\Name*[Walter]{de la Mare}| or\\ |\Name[Walter]{de la Mare}| or\\ |\FName[Walter]{de la Mare}|
% \item Next reference: \Name[Walter]{de la Mare}\\[0.5ex]

% |\CapThis\Name[Walter]{de la Mare}|
% \item Forename: \FName[Walter]{de la Mare}\\[0.5ex]
% |\FName[Walter]{de la Mare}|\\[2ex] The following illustrate the Continental style of particulate names. The first keeps particles in the index.
% \item First: \Name[Johann Wolfgang von]{Goethe}\\[0.5ex]

% \item Subsequent forename: \FName[Adolf]{Harnack}\\[0.5ex]
% |\FName[Adolf]{Harnack}|
% \end{enumerate}
% \subsubsection{Expert}
% The following examples deal with complicated or technical macros.
% \begin{enumerate}\setlength\itemsep{0pt}\small
% \item Index, but do not print a reference to ``Public, J.Q.'' \IndexName[J.Q.]{Public}\\[0.5ex]
% |\IndexName[J.Q.]{Public}|\\[0.5ex] Note that in Western names, the final optional parameters are ignored.
% \item Index, but do not print a reference to ``Plato'' \IndexName{Plato}\\[0.5ex]
% |\IndexName{Plato}|
% \item Index, but do not print a reference to ``Mao Tse-tung'' \IndexName{Mao}[Tse-tung]\\[0.5ex]
% |\IndexName{Mao}[Tse-tung]|
% \item Index, but do not print a reference to ``Henry VIII'' \IndexName{Henry}[VIII]\\[0.5ex]
% |\IndexName{Henry}[VIII]|
% \item Index, but do not print a reference to ``Ptolemy I Soter'' \IndexName{Ptolemy I}[Soter]\\[0.5ex]
% |\IndexName{Ptolemy I}[Soter]|\\[0.5ex] The following only work with the default \texttt{nocomma} option.
% \item Index, but do not print a reference to ``Gregory I'' \IndexName{Gregory, I}\\[0.5ex]
% |\IndexName{Gregory, I}|
% \item Index, but do not print a reference to ``Sun Yat-sen'' \IndexName{Sun, Yat-sen}\\[0.5ex]
% |\IndexName{Sun, Yat-sen}|
% \item Following a name, print a pseudonym in parentheses: \PName[Bob]{Hope}[Leslie Townes]{Hope}\\[0.5ex]
% |\PName[Bob]{Hope}%|\\|[Leslie Townes]{Hope}|
% \item Print a name that is only a \emph{see} reference to another: \AKA[Bob]{Hope}[Lester T.]{Hope}\\[0.5ex]
% |\AKA[Bob]{Hope}[Lester T.]{Hope}|\\[2ex] The following only works with the default \texttt{nocomma} option.
% \item Print a name and ``sobriquet'' for an ancient name, making it a cross-reference: \AKA{Leo, I}{Leo}[the Great]\\[0.5ex]
% |\AKA{Leo, I}{Leo}[the Great]|
% \item Print only a ``sobriquet'' after a \cmd{\Name} reference: \Name{Leo, I} ``\AKA*{Leo, I}{Leo}[the Great]''\\[0.5ex]
% |\Name{Leo, I}| |``\AKA*{Leo, I}%| |{Leo}[the Great]''|
% \end{enumerate}
% \subsubsection{Pitfalls}
% Avoiding the following pitfalls will save time and frustration:
% \begin{enumerate}\setlength\itemsep{0pt}\small
% \item Mixing sobriquets with modern forms fails due to the ``alternate name'' feature, e.g.:\\ |\Name[First]{Ancient}[Sobriquet]|\\ |\Name[King]{Number}[Sobriquet]|
% \item Using \cmd{\AKA} and \cmd{\PName} with sobriquet-based forms will fail unless you use comma-delimited suffixes. See Section \ref{sec:suffix}.
% \item Using a forename or first initials can prevent failure in some cases:\\[0.5ex]{\footnotesize OK: |\Name[J.]{Kreskin}[The Amazing]|\\ |(\AKA[J.]{Kreskin}[Joseph]{Kresge})|\\[0.5ex] FAIL: |\Name[]{Kreskin}[The Amazing]|\\ |(\AKA{Kreskin}[Joseph]{Kresge})|\\[0.5ex] FAIL: |\Name{Kreskin}[The Amazing]|\\ |(\AKA{Kreskin}[Joseph]{Kresge})|}
% \item \cmd{\Name} can shorten a reference even if you use the full name in the text.
% \item Unbalanced or incorrect \texttt{\{} braces \texttt{\}} and \texttt{[} brackets \texttt{]}, putting a star |*| after |\FName|, and forgetting periods in initials create errors that can be difficult to track. Leading spaces in macro arguments will create incorrectly sorted index entries.

% \DescribeMacro{\Name*}
% This macro generates two forms of the name: a printed form in the text and a form of the name that occurs in the index.
% The general syntax is:
% \begin{quote}
% \cmd{\Name}\oarg{forename(s)}\marg{surname(s)}\oarg{alternate names}\\
% \cmd{\Name*}\oarg{forename(s)}\marg{surname(s)}\oarg{alternate names}
% \end{quote}
%
% \noindent From now on we will abbreviate \emph{forename(s)} with \emph{FNN} and \emph{surname(s)} with \emph{SNN} at various points. The syntax descriptions do not capture exactly how the \cmd{\Name} macro behaves. The following table helps to show first and subsequent references:
%
% \begin{quote}\small
% \begin{tabular}{llll}\hline
% {\large\strut}\emph{FNN} & \emph{SNN} & Alternate Names & Result\\\hline
% \texttt{Albert} & \texttt {Einstein} & (none) & \Name[Albert]{Einstein}\\
% \texttt{Albert} & \texttt {Einstein} & (none) & \Name[Albert]{Einstein}\\
% (none) & \texttt{Confucius} & (none) & \Name{Confucius}\\
% (none) & \texttt{Confucius} & (none) & \Name{Confucius}\\
% \texttt{M.T.} & \texttt{Cicero} & \texttt{Marcus Tullius} & \Name[M.T.]{Cicero}[Marcus Tullius]\\
% \texttt{M.T.} & \texttt{Cicero} & \texttt{Marcus Tullius} & \Name[M.T.]{Cicero}[Marcus Tullius]\\
% (none) & \texttt{Charles} & \texttt{the Bald} & \Name{Charles}[the Bald]\\
% (none) & \texttt{Charles} & \texttt{the Bald} & \Name{Charles}[the Bald]\\\hline
% \end{tabular}
% \end{quote}
%
% \noindent Basically, \cmd{\Name} connects the \emph{FNN} to the \emph{SNN} to create respective printed and indexed forms, usually \emph{FNN}\,\emph{SNN} and \emph{SNN},\,\emph{FNN}. This takes care of most Western names. For those with one name, such as ancient figures or stage names, one can drop the \emph{FNN} so that \cmd{\Name} produces the result \emph{SNN} for both text and index.\cmd{\Name} always prints the surname or ``base name.''
%
% Sometimes you might want to have the option of using either an alternate set of forenames, like a nickname, or a sobriquet that functions as a surname for ancient figures. These two alternatives are handled by the final, optional field of \cmd{\Name}. If ``regular'' \emph{FNN} are present, then the alternate names conditionally will replace the \emph{FNN} in the printed form, but not in the indexed form. If no regular \emph{FNN} are present, then the alternate names will be appended to the \emph{SNN} in the printed form \emph{and} in the indexed form. You may choose to include or exclude nicknames and such, but you must always use the sobriquet form of a name consistently.
%
% I mentioned conditional use. The unstarred form prints the ``full name'' at the first occurrence, then only the partial form thereafter. The starred form always prints the full name. Both macros usually apply a different ``font  attribute'' to the name when it first appears in the running text.
%
% As long as the ``main'' \emph{FNN} are constant in Western-style names, the ``alternate names'' field can vary, yet the index entries will be constant. Sections \ref{sec:example} and  \ref{sec:start} contain a number of ``intermediate'' examples that illustrate this ability to swap out forenames. This is useful when dropping out references to middle initials in \cmd{\FName}. Alternate forenames only get printed in subsequent occurrences of \cmd{\Name*} and \cmd{\FName}. The surname argument is \emph{always} printed in \cmd{\Name*} and \cmd{\Name}.
%
% Another option employs a ``sobriquet'' feature for royal names and basic Eastern names. \cmd{\AKA} and \cmd{\PName} cannot refer to these forms, although they can use these forms in the \emph{second} name argument to construct a cross-reference. A workaround is discussed in Section \ref{sec:suffix}. The following method is the only one that works with the \texttt{comma} option. Valid ``sobriquet'' forms are:\\
%
% \bgroup\footnotesize\ForgetName{Henry}[VIII]
% \begin{tabular}{llp{1.2cm}ll}\hline
% {\normalsize\strut}\emph{FNN} & \emph{SNN} & Alternate Names & Result & Function\\\hline
% (none) & \texttt{Henry} & \texttt{VIII} & \Name{Henry}[VIII] & |\Name{Henry}[VIII]|\\
% (none) & \texttt{Henry} & \texttt{VIII} & \Name{Henry}[VIII] & |\Name{Henry}[VIII]|\\\hline
% (none) & \texttt{Chiang} & \texttt{Kai-shek} & \Name{Chiang}[Kai-shek] & |\Name{Chiang}[Kai-shek]|\\
% (none) & \texttt{Chiang} & \texttt{Kai-shek} & \Name{Chiang}[Kai-shek] & |\Name{Chiang}[Kai-shek]|\\\hline
% \end{tabular}
% \egroup\bigskip
%
% \noindent Again, alternate forenames \emph{override} the \emph{FNN} in the text. Sobriquets are \emph{appended} to \emph{SNN}. The presence or absence of \emph{FNN} triggers this difference between the two actions---\emph{this is a central concept}. 
%
% \emph{Note}: Throughout this manual I play a ``dirty trick'' that makes a name print as if it had not yet occurred. In some cases I make a first occurrence print as if the name already had occurred. This trick can be used, for example, to force the formatting of the first name in a chapter or section. See Section \ref{sec:Tweaks} for more.
%
% \subsubsection{\texttt{\bsc FName}}
%
% \DescribeMacro{\FName}
% This casual friend of \cmd{\Name} prints only ``first'' names except if a first use occurs, whereupon it prints a full, formatted name as set by the class options or the formatting macros. \cmd{\FName} is intended for Western-style names. The syntax is basically the same:
% \begin{quote}
% \cmd{\FName}\oarg{FNN}\marg{SNN}\oarg{alternate names}
% \end{quote}
% Remember that \cmd{\FName} \emph{has no starred form}. Next we see what it does:
%
% \begin{quote}\small
% \begin{tabular}{llll}\hline
% {\large\strut}\emph{FNN} & \emph{SNN} & Alternate Names & Result\\\hline
% \texttt{Albert} & \texttt {Einstein} & (none) & \FName[Albert]{Einstein}\\
% (none) & \texttt{Confucius} & (none) & \FName{Confucius}\\
% \texttt{M.T.} & \texttt{Cicero} & \texttt{Marcus Tullius} & \FName[M.T.]{Cicero}[Marcus Tullius]\\
% (none) & \texttt{Charles} & \texttt{the Bald} & \FName{Charles}[the Bald]\\\hline
% \end{tabular}
% \end{quote}
%
% \noindent If one accidentally referred to |\FName[Max]{Planck}| as a first reference, that would appear as \FName[Max]{Planck}. otherwise it would just be \FName[Max]{Planck}. For nicknames use the ``alternate names'' option. For example, aviation hero \Name[Chesley B.]{Sullenberger, III} can be noted as:
%
% \begin{quote}|``\FName[Chesley B.]{Sullenberger, III}[Sully]''|\quad``\FName[Chesley B.]{Sullenberger, III}[Sully]''\end{quote}
%
%\noindent A good way to cut keystrokes would be to assign the above macro to the control sequence \cmd{\Sully}. With comma-delimited suffixes we note special cases governed by the \texttt{nocomma} class option (see Section \ref{sec:suffix}). These include names like like \FName[J.D.]{Rock, III} and \FName{Charles, V}:
% \begin{quote}|\FName[J.D.]{Rock, III}|, ``\FName[J.D.]{Rock, III},'' |\FName{Charles, V}|, ``\FName{Charles, V}''\end{quote}
% \cmd{\FName} suppresses extra periods if a forename with initials occurs at the end of a sentence, as in the plot-line ``who shot \FName[J.D.]{Rock, III}.'' See also Section \ref{sec:suffix}.
%
% \subsection{Advanced Topics}
%
% \subsubsection{Error Handling}
% \label{sec:error}
%
% Except for \cmd{\ExcludeName}, the macros silently print any erroneous arguments in the text and emit warnings. Sometimes a warning is just a warning. \cmd{\PName} produces warnings via \cmd{\Name} and \cmd{\AKA}. Warnings result from:
% \begin{enumerate}\setlength{\itemsep}{-0.4ex}
% \item Using a cross-reference \oarg{alternate FNN}\marg{alternate SNN}\oarg{alt. names} created by \cmd{\AKA} as a reference in \cmd{\Name}, \cmd{\FName}, and \cmd{\PName}.
% \item Using a reference \oarg{FNN}\marg{SNN}\oarg{alternate names} created by \cmd{\Name}, \cmd{\FName}, and \cmd{\PName} as a cross-reference in \cmd{\AKA}.
% \item Using \cmd{\AKA} to create the same xref multiple times.
% \item Using \cmd{\ExcludeName} to exclude a name that has already been used.
% \end{enumerate}
% 
% \subsubsection{Naming Conventions}
%
% \DescribeMacro{\CapThis}
% English names with the particles \emph{de}, \emph{de\ la}, \emph{d'}, \emph{von}, \emph{van}, and \emph{ten} generally keep them with the last name, using varied capitalization. \emph{Le}, \emph{La}, and \emph{L'} are capitalized unless preceded by \emph{de}. In English, these particles go in the \emph{SNN} field of \cmd{\Name}, e.g., \ForgetName[Walter]{de la Mare}\Name[Walter]{de la Mare}. To capitalize the first particle in a subsequent \cmd{\Name} reference at the beginning of a sentence, use |\CapThis\Name[Walter]{de la Mare}|. \CapThis\Name[Walter]{de la Mare} will think it fair.
%
% Names foreign to English usually put these particles in the \emph{FNN} field of \cmd{\Name}. Yet these particles are not first names. Using \cmd{\FName} with alternate forenames overcomes this issue. Section \ref{sec:start} likely has the best illustration of this.
%
% \subsubsection{Hyphenation}
%
% I find it helpful to use respectively the \textsf{babel} or \textsf{polyglossia} packages with name hyphenation. If one is using English as the main language, the default hyphenation patterns may not suffice. For example, the name \Name[John]{Strietelmeier} may break thus: ``Stri-etelmeier.'' That is fixed by creating a \cmd{\de} macro equivalent to |\newcommand{\de}[1]{\foreignlanguage{ngerman}{#1}}| (using \textsf{babel}) and writing |\de{\Name[John]{Strietelmeier}}|.
%
% One can insert optional hyphens in the arguments of \cmd{\Name} and friends but that must be done \emph{consistently} to avoid variants being treated as different names.
%
% \subsubsection{\texttt{\bsc IndexName}}
% 
% \DescribeMacro{\IndexName}
% This macro creates an index entry like \cmd{\Name} and friends. It prints no text in the body and includes no special formatting. The syntax is similar to \cmd{\Name}:
% \begin{quote}
% \cmd{\IndexName}\oarg{FNN}\marg{SNN}\oarg{alternate names}
% \end{quote}
% \cmd{\IndexName} does not index the alternate names unless \emph{FNN} are absent, like \cmd{\Name} using the sobriquet feature. See also Section \ref{sec:SectionIndex} for switching indexing on and off.
%
% \subsubsection{\texttt{\bsc ExcludeName}}
% 
% \DescribeMacro{\ExcludeName}
% This prevents \cmd{\Name}, etc. from both formatting and indexing a specific name, but \emph{only if that name has not been used}. See also Section \ref{sec:error}. The syntax is:
% \begin{quote}
% \cmd{\ExcludeName}\oarg{FNN}\marg{SNN}\oarg{alternate names}
% \end{quote}
% To suppress only indexing but retain formatting, enclose \cmd{\Name}, etc. between \cmd{\IndexInactive} and \cmd{\IndexActive}.
%
% \subsubsection{Manual Index Entries}
% \label{sec:manual}
%
% \cmd{\Name} and friends produce index entries compatible with manual index entries since version 0.9. The \texttt{.idx} file is a helpful reference when linking manual entries with \textsf{nameauth} entries, although it is usually unnecessary to consult.
%
% \subsubsection{Suffix Removal}
% \label{sec:suffix}
% \changes{v0.85}{2012/02/05}{New suffix removal features}
% 
% \cmd{\Name}---not \cmd{\Name*}---truncates comma-delimited suffixes from last names. For example, it prints the name \Name[Oskar]{Hammerstein, II} the first time and \Name[Oskar]{Hammerstein, II} thereafter. One must always use a comma to activate this, e.g., |\Name[Oskar]{Hammerstein, II}|. The space after the comma is literal, but not manipulated by the package in case one wants to use a thin space.
%
% Again, \textbf{the comma is not optional with suffixes}. It is how this feature works. More than one comma in the \emph{SNN} argument of \cmd{\Name} and friends will cause unwanted results. Fortunately, that is unlikely.
%
%  These macros keep track of whether the name ends with the period of an abbreviation like ``Jr.'' and ``Sr.'' That should also work with abbreviations like ``d.~\"{A}.'' (\textit{der \"{A}ltere}). Two periods are not printed when the full name is printed at the end of a sentence. The following example shows possible combinations:
% 
% \ForgetName[Martin Luther]{King, Jr.}%
% \begin{quote}\small
% \begin{tabular}{ll}
% |\Name[Martin Luther]{King, Jr.}.| & \Name[Martin Luther]{King, Jr.}.\\
% |\Name[Martin Luther]{King, Jr.}.| & \Name[Martin Luther]{King, Jr.}.\\
% |\Name[Martin Luther]{King, Jr.}| & \Name[Martin Luther]{King, Jr.} (e.g., in a sentence)\\
% |\Name*[Martin Luther]{King, Jr.}.| & \Name*[Martin Luther]{King, Jr.}.\\
% |\Name*[Martin Luther]{King, Jr.}| & \Name*[Martin Luther]{King, Jr.}
% \end{tabular}
% \end{quote}
%
% Using the default class option \texttt{nocomma} with suffix removal, one can take advantage of the suffix feature to tweak more possibilities out of \cmd{\Name}. Instead of the sobriquet feature, one could use the following variants:
%
% \begin{quote}\small\ForgetName{Sun, Yat-sen}
% \begin{tabular}{llp{1.2cm}ll}\hline
% {\large\strut}\emph{FNN} & \emph{SNN} & Alternate Names & Result & Function\\\hline
% (none) & \texttt{Louis, XIV} & (none) & \Name{Louis, XIV} & |\Name{Louis, XIV}|\\
% (none) & \texttt{Louis, XIV} & (none) & \Name{Louis, XIV} & |\Name{Louis, XIV}|\\
% (none) & \texttt{Sun, Yat-sen} & (none) & \Name{Sun, Yat-sen} & |\Name{Sun, Yat-sen}|\\
% (none) & \texttt{Sun, Yat-sen} & (none) & \Name{Sun, Yat-sen} & |\Name{Sun, Yat-sen}|\\\hline
% \end{tabular}
% \end{quote}
%
% \noindent The benefit to using this form is that one can type |\Name*{Louis, XIV}, the| |``\AKA{Louis, XIV}{Sun King}''| and get \Name*{Louis, XIV}, the ``\AKA{Louis, XIV}{Sun King}'' in the text with an appropriate reference from ``Sun King'' to ``Louis XIV'' in the index. The sobriquet feature would otherwise prevent such usage.
%
% Even though suffix and sobriquet features look like they produce the same \emph{output} in the body text using the \texttt{nocomma} option, they are internally \emph{different}. They will not respect each other regarding ``first use,'' although they will (tentatively) cooperate in the index. Use each approach consistently. An example of ``dangerous'' use of these features occurs in Section \ref{sec:formatting}. The \texttt{comma} option will cause these forms above to have commas and behave differently. Again, \emph{caveat auctor}.
%
% \subsubsection{Pen Names: An Introduction}
% \label{sec:pennames}
% 
% The macro \cmd{\AKA} deals with pseudonyms, stage names, \emph{noms de plume}, etc. We already saw the suffix feature above as a workaround for sobriquets and Eastern names when using \cmd{\AKA}. Before we examine its function in detail, we touch on the only solution for some name forms, especially if one chooses the \texttt{comma} option:
%
% \begin{quote}
% \bgroup\ttfamily\small
% \verb!\index{Jean the Fearless|see{Jean sans Peur}}%!\\
% |\Name{Jean}[sans Peur]| (Jean the Fearless) was Duke of Burgundy\break from 1404 to 1419.
% \egroup
%
% \index{Jean the Fearless|see{Jean sans Peur}}%
% \Name{Jean}[sans Peur] (Jean the Fearless) was Duke of Burgundy from 1404 to 1419.
% \end{quote}
%
% \noindent The suffix workaround also can work with the above example, but be careful; see Section \ref{sec:formatting}.  A more complicated example is:
% \begin{quote}
% \bgroup\ttfamily\footnotesize
% \verb!\index{Doctor Angelicus@\textit{Doctor Angelicus}|see{Thomas Aquinas}}%!\\
% \verb!\index{Thomas of Aquino|see{Thomas Aquinas}}%!\\
% Perhaps the greatest medieval theologian was |\Name{Thomas}[Aquinas]| (Thomas of Aquino), also known as |\textit{Doctor Angelicus}|. His name ``Aquinas'' is not a surname, so many modern scholars simply refer to him as \break |\Name{Thomas}[Aquinas]|.
% \egroup
%
% \index{Doctor Angelicus=\textit{Doctor Angelicus}|see{Thomas Aquinas}}%
% \index{Thomas of Aquino|see{Thomas Aquinas}}%
% Perhaps the greatest medieval theologian was \Name{Thomas}[Aquinas] (Thomas of Aquino), also known as \textit{Doctor Angelicus}. His name ``Aquinas'' is not a surname, so many modern scholars simply refer to him as \Name{Thomas}[Aquinas].
% \end{quote}
% 
% \subsubsection{\texttt{\bsc AKA}}
%
% \DescribeMacro{\AKA}
% \DescribeMacro{\AKA*}
% The primary macro that handles aliases is \cmd{\AKA}. Its syntax is:
% \begin{quote}
% \cmd{\AKA}\oarg{FNN}\marg{SNN}\oarg{alternate FNN}\marg{alternate SNN}\oarg{alt. names}\\
% \cmd{\AKA*}\oarg{FNN}\marg{SNN}\oarg{alternate FNN}\marg{alternate SNN}\oarg{alt. names}
% \end{quote}
%
% \noindent Notice that the \emph{FNN} and \emph{SNN} arguments \emph{do not accept} the third argument field of \cmd{\Name}. This means that one cannot use \cmd{\AKA} to create a \emph{see} reference to a name with a sobriquet or to an Eastern name unless one uses the suffix feature mentioned previously. Here is a quick review of what works and what fails:
%
% \begin{quote}\footnotesize
% \begin{tabular}{llllll}\hline
% {\normalsize\strut}\emph{FNN} & \emph{SNN} & Alt. \emph{FNN} & Alt. \emph{SNN} & Alt. names & Result \\\hline
% {\small\strut}\texttt{Bob} & \texttt{Hope} & \texttt{Leslie Townes} & \texttt{Hope} & (none) & success\\
% {\small\strut}\dag\texttt{Bob} & \texttt{Hope} & \texttt{Leslie Townes} & \texttt{Hope} & \texttt{Lester T.} & success\\\hline
% {\small\strut}(none) & \texttt{Louis} & \texttt{XIV} & \texttt{Sun King} & (none) & FAIL\\
% {\small\strut}\ddag(none) & \texttt{Louis, XIV} & (none) & \texttt{Sun King} & (none) & success\\\hline
% {\small\strut}(none) & \texttt{Gregory} & \texttt{I} & \texttt{Gregory} & \texttt{the Great} & FAIL\\
% {\small\strut}\S (none) & \texttt{Gregory, I} & (none) & \texttt{Gregory} & \texttt{the Great} & success\\\hline
% \end{tabular}
%
% \smallskip\dag{} This succeeds, but replaces ``Leslie Townes'' with ``Lester T.''\\
% \ddag{} This form uses the \texttt{nocomma} feature.\\
% \S{} This produces different output, depending on whether \cmd{\AKA} or \cmd{\AKA*} is used.
% \end{quote}
%
% \noindent Since \cmd{\AKA} is designed to handle a number of otherwise incompatible needs, its use may be the most complex of all macros in this package. \cmd{\AKA} creates a cross reference. The target of this cross-reference is either \emph{SNN}, \emph{FNN} or just \emph{SNN}. The main entry in which the cross-reference occurs is constructed exactly like \cmd{\Name} handles its arguments. The \emph{alternate FNN} are replaced by the \emph{alternate names} if both exist. The \emph{alternate names} follow the \emph{alternate SNN} otherwise.
%
% The twist is the starred form \cmd{\AKA*}. If the starred form is used with the template (none)\marg{alternate SNN}\oarg{alt. names}, it only prints the \oarg{alt. names}. This allows it to be used in the manner of the example text in Section \ref{sec:example}. \cmd{\AKA} prints \marg{alternate SNN} followed by \oarg{alt. names}. A difference between this macro and \cmd{\Name} using sobriquets is that this macro creates a cross-reference and allows the ``sobriquet'' to be printed separately.
%
% \cmd{\AKA} only prints the alternate name. It assumes that a \cmd{\Name} macro occurs somewhere to create the page-indexed target of a cross-reference. No error checking otherwise occurs for this. The macro also prevents double periods.
%
%A brief example follows:
% 
% \begin{quote}
% \bgroup\ttfamily
% Today we consider |\AKA[George]{Eliot}[Mary Anne]{Evans}| and her literary contributions as |\Name[George]{Eliot}|.
% \egroup
%
% Today we consider \AKA[George]{Eliot}[Mary Anne]{Evans} and her literary contributions as \Name[George]{Eliot}.
% \end{quote}
% 
% \noindent The alternate name references generated by \cmd{\AKA} and \cmd{\AKA*} only work as cross-references and cannot be used with \cmd{\Name} and \cmd{\FName}, which print the alternate names and emit a warning. See also Section \ref{sec:error}.
%
% In certain cases, the alternate name might need to be indexed with page numbers. Do not use \cmd{\AKA} if that is so. Use \cmd{\Name} for both the main and the alternate names. Then create manual cross-references with \cmd{\index}, e.g.:\bigskip
%
% \bgroup\footnotesize\index{Rambam|seealso{Maimonides}}
% \begin{tabular}{p{0.7in}ll}\hline
% Authoritative Name & Alternate Name & Example of Use\\\hline
% \Name{Maimonides} & \AKA{Maimonides}{Moses ben-Maimon} & |\AKA{Maimonides}{Moses ben-Maimon}|\\
% \Name{Maimonides} & \Name{Rambam} & |\Name{Rambam}%|\\& & \verb!\index{Rambam|seealso{Maimonides}}!\\\hline
% \end{tabular}
% \egroup
%
% \bigskip\noindent\cmd{\AKA} will not create multiple instances of a cross-reference. This allows the macro \cmd{\ExcludeName} to work, but it also prevents the special case where one moniker applies to multiple people, e.g.: \PName*[Willebrord]{Snel van Royen}{Snellius} and his son \PName*[Rudolph]{Snel van Royen}{Snellius}. \cmd{\AKA} produces the first cross-reference; the user manually creates the second:
% \index{Snellius|see{Snel van Royen, Rudolph}}%
% \begin{quote}
% \verb!\index{Snellius|see{Snel van Royen, Rudolph}}!
% \end{quote}
% 
% \subsubsection{\texttt{\bsc PName}}
%
% \DescribeMacro{\PName}
% \cmd{\PName} is a ``convenience macro'' that sacrifices flexibility for simplicity. It does not implement \cmd{\AKA*} and it works best with Western-style names. It calls \cmd{\Name} or \cmd{\Name*} and prints a Western-style ``main'' name. It then always calls \cmd{\AKA} with a full alternate name and prints it in parentheses. The syntax is:
% \begin{quote}
% \cmd{\PName}\oarg{FNN}\marg{SNN}\oarg{lesser-known FNN}\marg{lesser-known SNN}
% \end{quote}
%
% \noindent The author determines the name that is indexed (the first name) and the subsequent name that only occurs as a \emph{see} reference. For example:
%
% \begin{quote}
% |\PName*[Mark]{Twain}[Samuel L.]{Clemens}| compared to\\
% |\PName[Mark]{Twain}[Samuel L.]{Clemens}|\\
% Print \PName*[Mark]{Twain}[Samuel L.]{Clemens} the first time it appears. Later, print \PName*[Mark]{Twain}[Samuel L.]{Clemens}. The form \cmd{\PName} later just prints \PName[Mark]{Twain}[Samuel L.]{Clemens}.\\[1ex]
% |\PName*{Voltaire}[François-Marie]{Arouet}| and\\
% |\PName{Voltaire}[François-Marie]{Arouet}|\\
% Print \PName{Voltaire}[François-Marie]{Arouet} the first time it appears. Later, print \PName{Voltaire}[François-Marie]{Arouet}.
% \end{quote}
%
% \noindent If you use the unstarred forms  \cmd{\PName} and \cmd{\Name}, you must remember that, just because you include a full name as a parameter does not mean that the full name will print. You could end up with ambiguous references to the same last name, e.g., ``Snel van Royen.'' You are responsible for checking this.

% \noindent One may add control sequences to names, thanks to the help of \Name*[Robert]{Schlicht}. The next example adds more accented characters under \textsf{inputenc}/\textsf{fontenc}:
%  \begin{quote}\small
% |\usepackage{newunicodechar}|\\
% |\DeclareTextSymbolDefault{\textlongs}{TS1}|\\
% |\DeclareTextSymbol{\textlongs}{TS1}{115}|\\
% |\newunicodechar{ſ}{\textlongs}|\\
% |\newunicodechar{ā}{\=a}|\\
% |\newunicodechar{ṃ}{\d m}|
% \end{quote}
%
% \noindent For some glyphs you will need fonts with TS1 glyphs, e.g., |\usepackage{lmodern}|. See also pages 455--63 in \emph{The Latex Companion}. This allows |\Name{Ghazāli}| to generate \IndexInactive\Name{Ghazāli}\IndexActive. Control sequences like |\=a| fail even in manual index entries when using \textsf{makeindex} and \texttt{gind.ist} because the equal sign is interpreted as a ``literal'' character, as mentioned by \Name[Dan]{Lueking}. I stopped |\Name| from indexing \IndexInactive\Name{Ghazāli}\IndexActive{} to prevent the entry ``ali'' sorted under ``Ghaz''.

% \subsection{Name Formatting}
% \label{sec:formatting}
%
% \DescribeMacro{\NamesFormat}
% The first time a name is printed, it is formatted with the font attribute stored in \cmd{\NamesFormat}. This is set with the class options or manually. \cmd{\NamesFormat} can use either the command form or the declaration form of selecting font attributes, e.g., \cmd{\textsc} or \cmd{\scshape}. By redefining this macro, one can ``hook'' into the special typesetting of the first occurrence of a name. Consider the following:
%
% \begin{quote}
% |\renewcommand{\NamesFormat}[1]{\textbf{#1}%|\\
% |\ifinner\else\marginpar{\scriptsize #1}\fi}|
% \end{quote}
% 
% \noindent If we \cmd{\let} the value of \cmd{\NamesFormat} to save the current value and implement a temporary change like the above, we get:
% \let\oldformat\NamesFormat
% \renewcommand{\NamesFormat}[1]{\textbf{#1}\ifinner\else\marginpar{\scriptsize #1}\fi}
%
%\begin{quote}
% \bgroup\ttfamily |\Name{Vlad III}[Dracula]| became known as Vlad Ţepeş, ``The\break Impaler,''  after his death. He was the son of\break |\Name{Vlad II}[Dracul]|, a member of the Order of the Dragon. Later references to |\Name{Vlad III}[Dracula]| appear thus.\egroup
%
% \Name{Vlad III}[Dracula] became known as Vlad Ţepeş, ``The Impaler,''  after his death. He was the son of \Name{Vlad II}[Dracul], a member of the Order of the Dragon. Later references to \Name{Vlad III}[Dracula] appear thus.
% \end{quote}
%
% \let\NamesFormat\oldformat
%
% \noindent After using \cmd{\let} to revert \cmd{\NamesFormat}, a first occurrence again takes the form: \ForgetName{Vlad III}[Dracula]\Name{Vlad III}[Dracula], while subsequent references are to \Name{Vlad III}[Dracula].\\
%
% Let me again stress that the forms above do not work with  \cmd{\PName} and \cmd{\AKA}. Consistently use either the suffix mechanism (Section \ref{sec:suffix}) or use as a guide the examples above for \Name*{Jean}[sans Peur] and \Name*{Thomas}[Aquinas]. If you use the suffix mechanism, you would use the following forms:
%
%\begin{quote}\ForgetName{Vlad III}[Dracula]\ForgetName{Vlad II}[Dracul]
% \bgroup\ttfamily |\Name{Vlad III, Dracula}| became known as \break |\AKA{Vlad III, Dracula}{Vlad}[Ţepeş]|,\break |``\AKA{Vlad III, Dracula}{Vlad}[the Impaler],''|  after his death. He was the son of |\Name{Vlad II, Dracul}|, a member of the Order of the Dragon. Later references to |\Name{Vlad III, Dracula}| appear thus.\egroup
%
% \Name{Vlad III, Dracula} became known as \AKA{Vlad III, Dracula}{Vlad}[Ţepeş], ``\AKA*{Vlad III, Dracula}{Vlad}[the Impaler],''  after his death. He was the son of \Name{Vlad II, Dracul}, a member of the Order of the Dragon. Later references to \Name{Vlad III, Dracula} appear thus.
% \end{quote}
%
% \noindent NOTE: The ``Dracula'' example is complex and the usual ``first use'' feature has been manipulated extensively to produce these results. If you mix casually the sobriquet and suffix forms, errors may ``bite.'' Puns aside, \Name{Vlad III}[Dracula] was a complex historical figure, as was his father, living in the no-man's land between the Ottoman Empire and the Holy Roman Empire.

% \DescribeMacro{\NamesActive}
% \DescribeMacro{\NamesInactive}
% Using the \texttt{frontmatter} option deactivates formatting until \cmd{\NamesActive} occurs. Another macro, \cmd{\NamesInactive}, will deactivate formatting again. These two macros toggle formatting on and off. The mechanism works in a complementary, yet independent manner. It can be used throughout the document.
% 
% Here we switch to the ``front matter'' mode with \cmd{\NamesInactive}:

% \label{sec:Tweaks}
% 
% Using these two macros may hinder the arbitrary rearrangement of text. I suggest that one wait until the final draft before implementing them.
%
% \DescribeMacro{\ForgetName}
% This macro is a ``dirty trick'' of sorts that takes the same optional and mandatory parameters used by \cmd{\Name}. It handles its arguments in the same way, except that it ignores the final parameter if \emph{FNN} are present. The syntax is:
% \begin{quote}
% \cmd{\ForgetName}\oarg{FNN}\marg{SNN}\oarg{alternate names}
% \end{quote}
%
% \noindent This macro causes \cmd{\Name} and friends to ``forget'' prior uses of a name with respect to typesetting. The next use will print as if it were a ``first use.'' Index entries and pseudonyms (see above) are \emph{never} forgotten.
% 
% \DescribeMacro{\SubvertName}
% This macro is the opposite of the one above. It takes the same parameters. It handles its arguments in the same manner. The syntax is:
% \begin{quote}
% \cmd{\SubvertName}\oarg{FNN}\marg{SNN}\oarg{alternate names}
% \end{quote}
%
% \noindent This macro causes \cmd{\Name} and friends to think that a prior use of a name already has occurred. The next use will print as if it were a ``subsequent use.''

\newcommand*{\@nameauth@CleanName}[1]%
{%
    \expandafter\zap@space\detokenize{#1} \@empty%
}
%    \end{macrocode}
% \end{macro}
% Thanks to \Name*[Heiko]{Oberdiek}, this macro produces a ``sanitized'' string based on the forename/surname parameters of \cmd{\Name} and friends. With this we can construct a control sequence name. Testing for the presence of that control sequence determines the existence of pseudonyms and the first occurrence of a name.\bigskip\hrule\bigskip
% \noindent The following macros parse a ``base'' name into a radix and a suffix. They are designed so that their function occurs at the time of macro expansion, not execution. This expandability is key to the proper indexing function of this package. They form the kernel of the suffix removal and comma suppression features.

}
%    \end{macrocode}
% \end{macro}
% Anything starting with a comma and ending with the end of the name is stripped off. That includes ``Sr.,'' ``Jr.,'' ``III,'' and so on. An extra comma is included at the end of the parameter when |\@nameauth@Root| is called directly from \cmd{\Name} and friends so that the delimiter list will always be correct. By using \cmd{\@nameauth@CheckComma} below, one can call this macro only when the parameter takes the form <a,b>. This allows one to select the root and suffix without having a trailing comma hanging about.

% \cmd{\Name} is the heart of this package. \Name*[Marc van]{Dongen} provided the basic structure.
%
%The reason why one sees seven outcomes repeated three times for twenty-one variations is because one must make different decisions based on the dynamic interaction of many factors beyond mere input. Three choices occur when one tries to use an ``alternate name'' defined by \cmd{\AKA} as an argument to \cmd{\Name}. The latter prints the arguments with comma suppression if appropriate, emits a warning, and exits. One cannot use \cmd{\ForgetName} to expunge a pen name. This is a deliberate decision to avoid corruption of the index cross-references.
%
% Regarding the remaining eighteen branches, one cannot assume that the name will terminate with a suffix like ``Jr.'' until a check has been run to determine if the suffix should be truncated. The Boolean and value parameters offer eight valid patterns of input. The first or subsequent use are two more, as are front or main matter use. Operations on suffixes are governed by the first or subsequent use. The formatting or non-formatting of output is governed both by a formatting Boolean and by first/subsequent use. A final choice deals with handling alternate names in the \cmd{\Forenames} macro.
%
% Here is how these many factors interrelate: \cmd{\Name} first checks for comma suppression. if so it stores a comma-suppressed version of the third parameter in \cmd{\Surnames}. Otherwise it stores an unchanged version in \cmd{\Surnames} and \cmd{\Surnames}. The former needs to be fully expanded for the double-period checking to work, thus using \cmd{\edef}. The latter should not be fully expanded when using the \textsf{memoir} class with the utf8 option of \textsf{inputenc}. This will be passed respectively to \cmd{\@nameauth@FmtName} and \cmd{\@nameauth@Index}.\\
% 
%\noindent \cmd{\Name} then checks for the forenames argument. Two outcomes are possible.
% \begin{enumerate}
% \item Forenames are present. In this case, the alternate names argument creates two choices.
% \begin{enumerate}
% \item The alternate names replace the forenames in the printed form, not the indexed form.
% \item The absence of alternate names will result in the forenames being used for both forms.
% \end{enumerate}
% \item Forenames are absent. In that case, the alternate names argument creates two different choices.
% \begin{enumerate}
% \item The alternate names are appended to the surnames in both printed and indexed forms.
% \item Only the surnames are used.
% \end{enumerate}
% \end{enumerate}
%
% The next branch involves the Boolean value \texttt{@nameauth@DoFormat}, which is controlled by \cmd{\NamesActive} and \cmd{\NamesInactive}. If formatting is active, choose the unstarred form of \cmd{\@nameauth@FmtName}, which applies the formatting hook. Otherwise use the starred form that applies no formatting.
%
% The state of  \texttt{@nameauth@DoFormat} also controls the suffix used in the control sequences: \texttt{!MN!} for main name or \texttt{!NF!} for no format. This is the heart of the \texttt{frontmatter} / \texttt{mainmatter} mechanism.
%
% Where longer and shorter versions of names are printed, there the star parameter controls those outcomes. Comma suppression is used or not, as appropriate, in the index entries. Note again that one must always use commas with suffixes in the input, even if commas are suppressed in the output.
%
% The use of \cmd{\expandafter} before \cmd{\@nameauth@CheckDot} works with the other use of \cmd{\expandafter} mentioned with \cmd{\@nameauth@EvalDot} above to move past the closing brace and fetch the period as lookahead. That is only done when the check for a terminal period in the name succeeds.
