+The schemata package
+Charles P. Schaum
+charles dot schaum at att dot net
+v0.5 from 2013/02/14
+
+Abstract
+
+The schemata package facilitates the creation of topical schemata, outlines that use braces (or facsimiles thereof) to illustrate the breakdown of concepts and categories in Scholastic thought from late medieval and early modern periods. This packages functions with both plain TeX and LaTeX.
+
+Files		Target distribution
+
+schemata.pdf	Documentation	(normally in TEXMFDIST/doc/generic/schemata)
+schemata.sty	Package file	(normally in TEXMFDIST/tex/generic/schemata)
+README		This file 	(normally in TEXMFDIST/doc/generic/schemata)
+
+		Source distribution
+
+Makefile	Automates building with GNU make 3.81
+schemata.ins	Installer
+schemata.dtx	LaTeX file containing both code and documentation
+
+Installation	Target distribution
+
+Unpack schemata.zip.
+
+Create the directories listed above. For TeX Live, TEXMFDIST is often /usr/local/texmf/<year>/texmf-dist on Posix-compliant systems. Manual installation calls rather for /usr/local/texlive/texmf-local or ~/texmf.
+
+MacTeX and MikTeX differ. Please refer to your distribution manual.
+
+Copy the target distribution files to their appropriate destinations.
+
+Run mktexlsr with the appropriate level of permissions.
+
+Source distribution notes:
+
+One can use the following commands to generate the target distribution:
+
+Generate the style file with any form of LaTeX:
+	$ pdflatex schemata.ins
+
+Generate the documentation (optimal with pdflatex):
+		pdflatex schemata.dtx
+		makeindex -s gglo.ist -o schemata.gls schemata.glo
+		makeindex -s gind.ist -o schemata.ind schemata.idx
+		pdflatex schemata.dtx
+		pdflatex schemata.dtx
+
+I used GNU make to automate the process:
+
+	Create the distribution (with full code listing}.
+
+	$ make
+
+Testing notes:
+
+This package is designed purposefully to be very basic.
+
+For testing purposes, the make file permits one to change the typesetting engine on the command line. The default is to build the package with pdflatex. See Makefile for more details.

+% \section{Introduction}
+%
+% This package emerged from my personal need to typeset diagrams based on seventeenth-century theology books. I have chosen to make it use a very ``bare-bones'' approach that is platform-agnostic in many cases, simple to implement, and immune to a number of special cases because it requires manual formatting.
+%
+% I would recommend that a package like \emph{TikZ}, something based on \MP, or some other powerful solution may have advantages, especially for those seeking a top-to-bottom diagram, such as that in; \textsc{H.~Dembowski}, \emph{Einf{\"u}hrung in die Christologie} (Darmstadt, 1993), 146. This package is meant to be basic and available in minimal \TeX{} installations.
+%
+% This package allows one to mimic (to some degree) the left-to-right schemata seen in books like the \emph{Loci Theologici} of Martin Chemnitz and the \emph{Clavis Scripturae Sacrae} of M. Flacius Illyricus.
+%
+% \section{Usage}
+%
+% \subsection{Package Options and Loading}
+%
+% Presently there are no package options.\\
+%
+% \begin{tabular}{ll}
+% Users of \LaTeX{} invoke: & |\usepackage{schemata}|\\[1ex]
+% Plain \TeX{} users will use: & |\input|\textvisiblespace|schemata.sty|
+% \end{tabular}
+%
+% \subsection{Overview}
+%
+% \DescribeMacro{\schema}
+% The ``simple'' form of a schema consists of one left-hand side containing vertically-centered vertical material, a brace, and one right-hand side containing vertically-centered vertical material:
+% \begin{quote}
+% \cmd{\schema}\oarg{type}\marg{left-hand side}\marg{right-hand side}
+% \end{quote}
+% The \meta{type} of a schema is |open| by default. Anything other than the exact string |open| will make it a ``closed'' schema where the left-hand side is bigger than the right and the direction of the brace reflects that. This approach is based on my experience that trying to figure out the size of left-hand and right-hand sides automatically can lead to strange corner cases. This manual solution recognizes that most schemata read and open from left to right.
+%
+% The \meta{left-hand side} and \meta{right-hand side} are vertically-centered material in a |\vbox|. This is intentional because one might want to insert a |\smallskip| or other adjustment as needed. One can put whatever is desired in these arguments. An example in \LaTeX{} might be a one-column tabular environment, e.g.:
+% \begin{multicols}{2}
+% \noindent Code:\\[2ex]
+% |\schema%|\\
+% |{%|\\
+% |  \hbox{\begin{tabular}{@{}l@{}}|\\
+% |    This conists\\|\\
+% |    of stuff|\\
+% |  \end{tabular}}|\\
+% |}%|\\
+% \noindent|{%|\\
+% |  \schemabox{%|\\
+% |    And here\\|\\
+% |    we have\\|\\
+% |    more stuff%|\\
+% |  }%|\\
+% |}|\\
+% \columnbreak\\
+% \noindent Result:\\[2ex]
+% \schema%
+% {%
+%   \hbox{\begin{tabular}{@{}l@{}}
+%     This conists\\
+%     of stuff\\
+%   \end{tabular}}
+% }%
+% {%
+%   \schemabox{%
+%     And here\\
+%     we have\\
+%     more stuff%
+%   }%
+% }
+%
+% \noindent Note how the results of the two sides are roughly the same. In fact, if one uses a |p{|\meta{width}|}| argument with a tabular, one will get almost the same results seen with a |\schemabox| also using a width argument. The difference is that the latter is intended for use in plain \TeX.
+%
+% The |\schemabox| macro is a ``stack'' of |\hbox| content within a |\vbox|. We will cover it below after we introduce the |\Schema| macro.
+% \end{multicols}
+% \clearpage
+% \DescribeMacro{\Schema}
+% The ``complex'' form of a schema consists of one left-hand side containing vertically-centered vertical material, a brace, and one right-hand side of vertically-centered vertical material:
+% \begin{quote}
+% \cmd{\Schema}\oarg{type}\marg{adjust}\marg{size}\marg{left-hand side}\marg{right-hand side}
+% \end{quote}
+%The \meta{type} of a schema is |open| by default. Anything other than the exact string |open| will make it a ``closed'' schema as above.
+%
+%Both \meta{adjust} and \meta{size} should be expressed in ``ex'', loosely interpreted as multiples of lines. Since an |hbox{\strut}| is 2.88538 ex high and |\vcenter| halves vertical height, the values are multiplied internally by 1.44265.
+%
+%Actually, \meta{adjust} must be \emph{double} the number of ``ex'' lines that a brace must go up (negative value) or down (positive value). By making one enter |-5ex| to pull a brace up 2.5 lines, one can use a whole number instead of entering many decimals.
+%
+% {\bfseries Note:} The value of \meta{size} always should be positive.\smallskip
+%
+% Admittedly, this method is nothing short of ugly. Yet it scales quite well and allows one to guess lengths by counting lines (even in the source) instead of measuring printed or displayed output.\\
+%
+% \DescribeMacro{\schemabox}
+% This box stacks one or more lines of |\hbox|-enclosed material in a |\vbox|. It redefines the control sequence |\\| in a manner that terminates the current |\hbox| and begins a new one.
+% \begin{quote}
+% \cmd{\schemabox}\oarg{width}\marg{text}
+% \end{quote}
+% The \meta{width} of a |\schemabox| is a dimension, e.g. 3cm. No wrapping takes place. Each line of \meta{text} must be terminated explicitly by |\\|, except the final line. The first line of a |\schemabox| inserts a |\strut| for aesthetic reasons.
+%
+% \subsection{Tutorial}
+%
+% \subsubsection{Starting Off Basic}
+%
+% Imagine that you are using a computer to simulate the physical typesetting of a seventeenth-century schema. To begin with, you try the following schema:
+% \begin{multicols}{2}
+% \noindent Code:\\[2ex]
+% |\schema{a}{b\\c}|\\
+% \noindent Result:\\[2ex]
+% \schema{a}{b\\c}
+% \end{multicols}
+% \noindent That did not go well. Then you remember this weird |\schemabox| that just might work. You |\let| the control sequence to the shorter |\SB| and you get:
+% \begin{multicols}{2}
+% \noindent Code:\\[2ex]
+% |\let\SB\schemabox|\\
+% |\schema{\SB{a}}{\SB{b\\c}}|\\
+% \noindent Result:\\[2ex]
+% \let\SB\schemabox
+% \schema{\SB{a}}{\SB{b\\c}}
+% \end{multicols}
+%
+% Now we are getting somewhere! Note that ``one-liners'' pretty much look ugly no matter how you do them. For example:  
+% \begin{multicols}{2}
+% \noindent Code:\\[2ex]
+% |\let\SB\schemabox|\\
+% |$\hbox{a}\left\lbrace%|\\
+% |    \hbox{bp}\right.$|\\
+% |$\vcenter{\hbox{a}}\left\lbrace%|\\
+% |    \vcenter{\hbox{b}}\right.$|\\
+% |$\vcenter{\hbox{\strut a}}%|\\
+% |  \left\lbrace%|\\
+% |    \vcenter{\hbox{\strut bp}}%|\\
+% |  \right.$|\\
+% |\schema{\SB{a}}{\SB{bp}}|\\
+% \columnbreak\\
+% \noindent Result:\\[6ex]
+% \let\SB\schemabox\bgroup\LARGE
+% $\hbox{a}%
+%   \left\lbrace%
+%     \hbox{bp}%
+%   \right.$\\[1ex]
+% $\vcenter{\hbox{a}}%
+%   \left\lbrace%
+%     \vcenter{\hbox{b}}%
+%   \right.$\\[0.5ex]
+% $\vcenter{\hbox{\strut a}}%
+%   \left\lbrace%
+%     \vcenter{\hbox{\strut bp}}%
+%   \right.$\\[1.6ex]
+% \schema{\SB{a}}{\SB{bp}}\egroup
+% \end{multicols}
+% \noindent The first example has aligned baselines, but the open brace appears to drop too low (in order to enclose also the depth, not just the height of the material). The second shows how vertical centering can cause baselines not to match up in one-liners of a different height. The third example shows how a |\strut| will fix that issue. The final example shows how this package deals with one-liners. A |\schemabox| adds a strut in the first line to make multi-line schemata look better. A height of 1.44265ex is automatically added to the brace height, also for multi-line schemata.
+%
+% \subsubsection{\emph{Loci} 101}
+%
+% Since we know something about schemata and how to do them, let's try a few examples from \emph{Loci Theologici}. We begin with this simple example:\\
+%
+%\schema
+%{%
+%  \schemabox{Subjectum theo-\\
+%      logi\ae{} est Notitia\\
+%      Dei. Considerat\\
+%      ergo, Dei, vel}
+%}
+%{%
+%  \schema
+%  {%
+%    \schemabox{\textsc{Essentiam},}
+%  }
+%  {%
+%    \schemabox{Unitate natur\ae{}.\\
+%        Trinitate personarum.\\
+%        Operibus ad intra.}}
+%  \schema
+%  {%
+%    \schemabox{\textsc{Voluntatem},\\
+%        manifestatam in\\
+%        operibus ad extra;\\
+%        ut in}
+%  }
+%  {%
+%    \schemabox{Creatione.\\
+%        Sustentatione natur\ae{} laps\ae{}.\\
+%        Reparatione.\\
+%        Conversione.\\
+%        Justificatione.\\
+%        Sanctificatione \&\\
+%        Glorificatione ejusdem.}
+%  }
+%}\vspace{1ex}
+% \noindent Something is off here. The ``simple'' schema automatically adjusts the brace height to the right-hand side. But that includes the \emph{entire} right-hand side. We shall see later that schemata also can nest left and right-hand sides. This package requires manual alignment and adjustment.
+%
+% \bgroup\footnotesize%
+% \begin{multicols}{2}
+% \noindent Initial Code:\\[1ex]
+%|\schema% <---change this|\\
+%|{%|\\
+%|  \schemabox{Subjectum theo-\\|\\
+%|      logi\ae{} est Notitia\\|\\
+%|      Dei. Considerat\\|\\

+%|}|\\
+%|{%|\\
+%|  \schema|\\
+%|  {%|\\
+%|    \schemabox{\textsc{Essentiam},}|\\
+%|  }|\\
+%|  {%|\\

+%|  }|\\
+%|  {%|\\
+%|    \schemabox{Creatione.\\|\\
+%|        Sustentatione natur\ae{} %|\\
+%|          laps\ae{}.\\|\\

+%|        Conversione.\\|\\
+%|        Justificatione.\\|\\
+%|        Sanctificatione \&\\|\\
+%|        Glorificatione ejusdem.}|\\
+%|  }|\\
+%|}|\columnbreak\\
+% \noindent Subsequent Changes:\\[1ex]
+%|\Schema{-1ex}{8.6ex}|\dots\\
+%\dots|\smallskip|\dots\\
+%
+% The commented text |% <---add space| in the listing to the left, at the end of the schema beginning with ``\textsc{Essentiam},'' indicates where a little vertical space between the right-hand ``leaves'' of the ``tree'' might help, so we adjust that first in order to set the braces properly. We remove the comment and insert a |\smallskip|. The general rule is:\\
+%
+% \noindent\ \ |\schema|\dots\marg{right-hand side}\meta{vert-space}
+%
+% \noindent\ \ |\Schema|\dots\marg{right-hand side}\meta{vert-space}\\
+%
+% \noindent One also may insert space within a |\schemabox|, but one should avoid doing that in either the first or last lines.
+%
+% Having adjusted the ``leaves,'' we now work toward the ``root.'' The |\Schema| macro requires manual brace adjustment and sizing. It is best used in cases where either the left or right-hand sides include a |\schema| or a |\Schema|. Manual adjustment is achieved by counting lines, estimating, and refining the estimate.
+%
+% Observe that there is approximately eight lines from ``\textsc{Essentiam}'' down to ``ut in.'' Estimate \meta{size} to |8ex| and \meta{adjust} to |0ex|. The large brace will be a little too low. Set \meta{adjust} to |-1ex| to raise the brace about half a line and to lower the left-hand side about half a line, keeping everything centered. Finally, setting \meta{size} to |8.6ex| gives a better result.
+%
+% \end{multicols}
+% \egroup
+%\Schema{-1ex}{8.6ex}
+%{%
+%  \schemabox{Subjectum theo-\\
+%      logi\ae{} est Notitia\\
+%      Dei. Considerat\\
+%      ergo, Dei, vel}
+%}
+%{%
+%  \schema
+%  {%
+%    \schemabox{\textsc{Essentiam},}
+%  }
+%  {%
+%    \schemabox{Unitate natur\ae{}.\\
+%        Trinitate personarum.\\
+%        Operibus ad intra.}
+%  }\smallskip
+%  \schema
+%  {%
+%    \schemabox{\textsc{Voluntatem},\\
+%        manifestatam in\\
+%        operibus ad extra;\\
+%        ut in}
+%  }
+%  {%
+%    \schemabox{Creatione.\\

+%          laps\ae{}.\\

+%        Justificatione.\\
+%        Sanctificatione \&\\
+%        Glorificatione ejusdem.}
+%  }
+%}\medskip
+%
+% \noindent Before we proceed, it may be helpful to note that many schemata, such as ones that illustrate the relationship of figures and tropes to the literal sense of a text, are no more complex than this first example.
+% \clearpage
+%
+% \subsubsection{Going Big}
+%
+% We begin with the following example, where the |\Schema| braces all have dummy values of |0ex| \meta{adjust} and |5ex| \meta{size}. Perhaps the indentation helps to give a sense of the nesting and how the result might end up:
+%
+% \bgroup\footnotesize%
+% \begin{multicols}{2}
+%\noindent |\Schema{0ex}{5ex}|\\
+%|{%|\\
+%|  \schemabox{Subjectum \& summa\\|\\

+%
+% It really is necessary to work from right to left here. One might think that he or she can guess roughly how big a brace might be. While that may be true, what will happen if you try to size the braces before spacing out the text on the right-hand side is that you will have to go back and forth, tweaking this and that, until you get what you want. That is a waste of time and a source of frustration. Steel yourself to avoid temptation and begin rigorously by adding vertical space after selected instances of |\Schema| or |\schema|, or within a |\schemabox|. The list on the next page shows the changes.

+% This is the ``simple'' version of a schema. It vertically centers one box of internal vertical material on the left-hand side with one box of internal vertical material on the right-hand side. It puts a ``simple'' brace between the boxes based on the height of the box and the option passed to the schema. By default, a schema has a box to the left, an open brace, and a box to the right. If any optional argument other than "open" is used, the schema prints a box to the left, a close brace, and a box to the right.
