+%
+% \noindent
+% \emph{Grundgesetze.sty} is a \LaTeX2e\ package for typesetting
+% Gottlob Frege's \emph{begriffs\-schrift} [concept-script] formalism
+% in the style of his \emph{Grundgesetze der Arithmetik} (1893/1903).
+% \emph{Grundgesetze.sty} was developed for the 2013 English edition
+% of Frege's book.\footnote{Gottlob Frege: \emph{Basic Laws of Arithmetic}.
+% Translated and edited by Philip A. Ebert and Marcus Rossberg. Oxford 2013.}
+% The package is based on Josh Parsons's \emph{begriff.sty} which renders
+% the formalism in the style of Frege's earlier work,
+% \emph{Begriffsschrift} (1879). It was amended by Richard~G.~Heck~Jr.,
+% J.\,J.~Green, Agust\'in~Rayo, and Marcus~Rossberg. Thanks to
+% Philip~A.~Ebert for testing, comments, and suggestions. Note that Frege's
+% defined function symbols are not rendered by this package, but rather
+% by J.\,J.~Green's \emph{fge.sty}.
+%
+% \section{Options}
+%
+% At present the only package option is |bguq|, which causes the package
+% to use the |bguq| font for an alternative universal quantifier
+% (concavity). Of course, one must have the |bguq| font
+% installed to use this option, but it is included in recent versions
+% of the big \TeX\ distrubtions.
+%
+% \section{Basic Commands}
+%
+% \DescribeMacro{\GGhorizontal}
+% \indent The horizontal, $\GGhorizontal$
+%
+% \DescribeMacro{\GGnot}
+% The negation-stroke, $\GGnot$
+%
+% \DescribeMacro{\GGconditional}
+% Conditional-stroke: called as |\GGconditional{p}{q}}| yields
+% $\GGconditional{p}{q}$ (i.e., `$p\supset q$')
+%
+% \DescribeMacro{\GGquant}
+% Concavity: called as |\GGquant{\mathfrak a}| gives
+% $\GGquant{\mathfrak a}$ (i.e., universal quantifier,
+% `$\mathfrak{a}$' is the quantified variable)
+%
+% \DescribeMacro{\GGjudge}
+% Judgement-stroke, $\GGjudge$
+%
+% \DescribeMacro{\GGdef}
+% Definition-stroke, $\GGdef$
+%
+% \DescribeMacro{\GGbracket}
+% Automatically scaling brackets, |\GGbracket{\ldots}| yields
+% $\GGbracket{\ldots}$ (see examples)
+%
+% \DescribeMacro{\GGsqbracket}
+% Analogous square brackets, $\GGsqbracket{\ldots}$
+%
+% A complete list of commands and compatibility synonymns in
+% the package can be found in Table~\ref{table:allmacros}, and
+% the lengths parameterising the appearance of the output in
+% Table~\ref{table:lengths}.
+%
+% \subsection{Examples}
+%
+% \begin{itemize}
+%
+% \item
+%\begin{verbatim}
+%\GGjudge \GGquant{\mathfrak a} \mathfrak a = \mathfrak a
+%\end{verbatim}
+% yields
+% \begin{equation*}
+% \GGjudge \GGquant{\mathfrak a} \mathfrak a = \mathfrak a
+% \end{equation*}
+%
+%
+% \item
+%\begin{verbatim}
+%\GGjudge \GGnot \GGquant{\mathfrak F} \GGnot
+% \GGquant{\mathfrak a} \mathfrak{Fa}
+%\end{verbatim}
+% yields
+% \begin{equation*}
+% \GGjudge \GGnot \GGquant{\mathfrak F} \GGnot
+% \GGquant{\mathfrak a} \mathfrak{Fa}
+% \end{equation*}
+%
+% \item
+%\begin{verbatim}
+%\GGjudge \GGconditional{(\GGhorizontal p)}{p}
+%\end{verbatim}
+% yields
+% \begin{equation*}
+% \GGjudge \GGconditional{(\GGhorizontal p)}{p}
+% \end{equation*}
+%
+% \item
+%\begin{verbatim}
+%\GGjudge \GGbracket{\GGconditional{p}{q}} =
+% \GGbracket{\GGconditional{\GGnot q}{\GGnot p}}
+%\end{verbatim}
+% yields
+% \begin{equation*}
+% \GGjudge \GGbracket{\GGconditional{p}{q}} =
+% \GGbracket{\GGconditional{\GGnot q}{\GGnot p}}
+% \end{equation*}
+%
+% \end{itemize}
+%
+% There are further examples, including Frege's basic laws of logic,
+% available for download on \texttt{www.frege.info}.
+%
+%
+% \section{Advanced Typesetting}
+%
+% \subsection{Left-alignment of terminal forumlae:
+% \texttt{\textbackslash GGterm}\label{term}}
+%
+% Conditional-strokes, negation-strokes, and concavities that are
+% embedded in conditionals can result in a ragged appearance of the
+% formula:
+%
+% \begin{itemize}
+%
+% \item
+%\begin{verbatim}
+%\GGjudge\GGconditional{p}{\GGconditional{q}{p}}
+%\end{verbatim}
+% yields:
+% \begin{equation*}
+% \GGjudge\GGconditional{p}{\GGconditional{q}{p}}
+% \end{equation*}
+%
+% \item
+%\begin{verbatim}
+%\GGjudge\GGconditional{Fa}
+% {\GGnot \GGquant{\mathfrak a} \GGnot F \mathfrak a}
+%\end{verbatim}
+% yields:
+% \begin{equation*}
+% \GGjudge\GGconditional{Fa}
+% {\GGnot \GGquant{\mathfrak a} \GGnot F \mathfrak a}
+% \end{equation*}
+%
+%% \end{itemize}
+%
+% In Frege's original work, the component formulae of conditionals
+% are left-aligned. This can be achieved by marking ``terminal formulae''
+% using the command |\GGterm{|$\langle\text{math}\rangle$|}|; the length
+% |\GGlinewidth| specifies the distance of the terminal formula from
+% the left end of the whole formula (typically, `\,$\GGjudge\!$'):
+%
+% \begin{itemize}
+%
+% \item
+%\begin{verbatim}
+%\setlength{\GGlinewidth}{9.2pt} \GGjudge
+%\GGconditional
+% {\GGterm{p}}
+% {\GGconditional{\GGterm{q}}
+% {\GGterm{p}}}
+%\end{verbatim}
+% yields:
+% \begin{equation*}
+% \setlength{\GGlinewidth}{9.2pt}
+% \GGjudge\GGconditional{\GGterm{p}}{\GGconditional{\GGterm{q}}{\GGterm{p}}}
+% \end{equation*}
+%
+% \item
+%\begin{verbatim}
+%\setlength{\GGlinewidth}{25.2pt}
+%\GGjudge\GGconditional{\GGterm{Fa}}
+% {\GGnot \GGquant{\mathfrak a} \GGnot
+% \GGterm{F \mathfrak a}}
+%\end{verbatim}
+% yields:
+% \begin{equation*}
+% \setlength{\GGlinewidth}{25.2pt}
+% \GGjudge\GGconditional{\GGterm{Fa}}
+% {\GGnot \GGquant{\mathfrak a} \GGnot
+% F \mathfrak a}
+% \end{equation*}
+%
+% \end{itemize}
+%
+% \begin{table}[ph]
+% \begin{center}
+% \begin{tabular}{lp{7mm}l}
+% \toprule
+% negation-stroke & \GGnot & 4.4pt\\
+% conditional-stroke & $\GGconditional{}{}$ & 4.4pt \\
+% concavity & $\GGquant{}$ & 11.6pt \\
+% judgement-stroke: & \GGjudge & \\
+% \hspace{10pt}present & & add .4pt\\
+% \hspace{10pt}not present & & subtract 2pt\\
+% \bottomrule
+% \end{tabular}
+% \end{center}
+% \caption{Lengths of embedded symbols\label{table:embedded}}
+% \end{table}
+%
+% The correct values for |\GGlinewidth| for each formula can be
+% determined by adding up the lengths
+% of the embedded symbols, as given in Table~\ref{table:embedded},
+% or by using a GUI that allows producing \LaTeX\ and XML code for
+% \emph{begriffsschrift} formulae via mouse-click and that will
+% calculate and output the correct values. The GUI is available for
+% download on \texttt{www.frege.info}.
+%
+% \subsection{Adding horizontal lengths manually:
+% \texttt{\textbackslash GGnonot}, etc.}
+%
+% Readability is sometimes aided by moving, e.g., negations to the
+% right end of the horizontal in a complex formula. For instance,
+% Frege nearly always preferred the rendering displayed on the right
+% in these types of formulae:
+%
+% \begin{center}
+% \begin{tabular}{rp{20mm}p{20mm}}
+% (a) &
+% \GGjudge\GGconditional{\GGquant{\mathfrak a}
+% \GGnot f(\mathfrak a)}{\GGnot\GGnoquant f(a)} &
+% \GGjudge\GGconditional{\GGquant{\mathfrak a}
+% \GGnot f(\mathfrak a)}{\GGnoquant\GGnot f(a)}\\ \addlinespace[10pt]
+%
+% (b) &
+% \GGjudge\GGconditional{\GGquant{\mathfrak a}
+% \GGconditional{f(\mathfrak a)}{g(\mathfrak a)}}
+% {\GGconditional{\GGnoquant f(a)}{\GGnoquant g(a)}} &
+% \GGjudge\GGconditional{\GGquant{\mathfrak a}
+% \GGconditional{f(\mathfrak a)}{g(\mathfrak a)}}
+% {\GGnoquant\GGconditional{f(a)}{g(a)}}\\ \addlinespace[10pt]
+%
+% (c) &
+% \GGjudge\GGconditional{\GGnot\GGnonot f(a)}
+% {\GGconditional{\GGnonot f(b)}{\GGnot a=b}} &
+% \GGjudge\GGconditional{\GGnonot\GGnot f(a)}
+% {\GGconditional{\GGnonot f(b)}{\GGnot a=b}}
+% \end{tabular}
+% \end{center}
+%
+% The right-hand formulae are produced by inserting commands
+% for horizontals of the appropriate length directly at the
+% position where the ``space'' should appear. The three
+% right-hand formulae above are created in this way:
+% \begin{itemize}
+% \item[(a)] \begin{verbatim}\GGjudge \GGconditional
+% {\GGquant{\mathfrak a} \GGnot f(\mathfrak a)}
+% {\GGnoquant \GGnot f(a)}\end{verbatim}
+% \item[(b)] \begin{verbatim}\GGjudge \GGconditional
+% {\GGquant{\mathfrak a}
+% \GGconditional{f(\mathfrak a)}{g(\mathfrak a)}}
+% {\GGnoquant \GGconditional{f(a)}{g(a)}}\end{verbatim}
+% \item[(c)] \begin{verbatim}\GGjudge \GGconditional
+% {\GGnonot \GGnot f(a)}
+% {\GGconditional{\GGnonot f(b)}{\GGnot a=b}}\end{verbatim}
+% \end{itemize}
+%
+% \section{Comparison and compatibility with \emph{begriff.sty}}
+%
+% Josh Parsons's \emph{begriff.sty}, on which \emph{grundgesetze.sty}
+% is based, is closer in appearance to Frege's formalism as it is
+% presented in Frege's first book, \emph{Begriffs\-schrift} (1879).
+% The corresponing commands were given different names so that both
+% pack\-ages can be used in the same \TeX~document; see Table~\ref{table:compat}.
+%
+% \begin{table}[hp]
+% \begin{tabular}{lp{16mm}p{13mm}l}
+% \toprule
+% \multicolumn{2}{l}{\emph{begriff.sty}} &

+%
+% \subsection{Conversion of a \emph{begriff.sty} document into a
+% \emph{grundgesetze.sty} document}
+%
+% A straightforward way to convert the a \LaTeX\ document that uses
+% \emph{begriff.sty} into one that uses \emph{grundgesetze.sty} without
+% manually exchanging the commands is to find and replace (using wrap
+% search) ``|\BG|" by ``|\GG|". Synonyms have been added to
+% \emph{grundgesetze.sty} to allow the use of all \emph{begriff.sty}
+% commands ``translated" in this way (see Table~\ref{table:allmacros}).
+%
+% \begin{table}[hp]
