+\section{Introduction}
+This note describes a package of \LaTeX\ macros for printing
+Z and Object-Z specifications. The macros and this note are
+based originally on Mike Spivey's \verb'zed.sty' macros and documentation.
+The package does several related things for you:
+\begin{itemize}
+\item It loads extra fonts and defines mnemonics
+ for the Z symbols they contain.
+\item It defines macros for some Z symbols (e.g. $\pinj$) which
+ don't appear in any of our fonts.
+\item It fixes the way \TeX\ sets letters in mathematical formulas so
+ that multi-character identifiers look better.
+\item It provides various brands of `boxed mathematics'
+ which appear in Z and Object-Z specifications.
+\end{itemize}
+
+The package is kept in a file {\tt oz.sty}
+in the directory \verb|/usr/local/lib/tex/localinputs|.
+This directory should be mentioned in your \verb|TEXINPUTS| shell variable.
+To use the macros you just begin your \LaTeX\ document with something like:
+\begin{quote}
+\begin{verbatim}
+\documentstyle[11pt,oz]{article}
+\end{verbatim}
+\end{quote}
+\vspace*{-1.5ex}
+
+\section{Schema Boxes}
+
+The example below shows a schema on the left and what you
+need to say to get it on the right.
+
+\begin{example}
+\begin{schema}{BirthdayBook}
+ known: \pset NAME \\
+ birthday: NAME \pfun DATE
+\ST
+ known = \dom birthday
+\end{schema}
+\end{example}
+
+The command \verb|\ST| (read `Such That') is the same as the previously used
+command \verb|\where| which has been kept as an alias for upward compatibility.
+If you want a schema with no name, just a horizontal rule at the top,
+use the \verb|schema*| environment instead.
+You can set various parameters (see Section 7) to change the box style,
+for example:
+
+\begin{example}
+$BirthdayBook \sdef \lsch ... \rsch$
+\end{example}
+
+A generic schema is produced as follows.
+
+\begin{example}
+\begin{genschema}{Pool}{RESOURCE}
+owner : RESOURCE \pfun USER \\
+free : \pset RESOURCE
+\ST
+(\dom owner) \uni free = RESOURCE \\
+(\dom owner) \int free = \emptyset
+\end{genschema}
+\end{example}
+
+\section{Axiomatic definitions}
+
+A `liberal' axiomatic definition is produced as follows.
+
+\begin{example}
+\begin{axdef}
+limit : \nat
+\ST
+limit \leq 65536
+\end{axdef}
+\end{example}
+
+A `generic' axiomatic definition is produced as follows.
+
+\begin{example}
+\begin{gendef}{X,Y}
+first : X \prod Y \tfun X
+\ST
+\all x : X; y : Y \dot first(x,y) = x
+\end{gendef}
+\end{example}
+
+A `unique' axiomatic definition is produced as follows.
+
+\begin{example}
+\begin{uniqdef}
+\pi : \real
+\ST
+\pi = 3.14159265\ldots
+\end{uniqdef}
+\end{example}
+
+\section{Object-Z Class Boxes}
+
+Object-Z allows class types to be defined using a box very similar to
+the schema box previously described. It allows the previously
+described boxed environments (as well as nested sub-classes) to be
+placed within a class box. In addition, special names can be used for
+some of the boxed-environments when they appear within a class box.
+The following example illustrates a class definition.
+
+\begin{example}
+\begin{class}{Shape}
+\also
+colour : Colour \\
+\begin{axdef}
+perim : \real
+\ST
+perim > 0
+\end{axdef} \\
+\begin{classcom}
+This class has 2 constants
+$colour$ and $perim$.
+\end{classcom} \\
+\begin{state}
+x, y : \real
+\end{state} \\
+\begin{init}
+x = y = 0
+\end{init} \\
+\begin{op}{Translate}
+\Delta (x,y) \\
+dx?, dy? : \real
+\ST
+x' = x + dx? \\
+y' = y + dy?
+\end{op}
+\end{class}
+\end{example}
+
+The \verb|classcom| environment hasn't been seen before.
+It creates a paragraph of text with the same margins as used
+for schemas and other Z environments. It uses a special font
+intended for use when placing comments inside classes.
+A similar environment, \verb|zpar|, uses the same margins
+but with the normal roman font.
+
+The \verb|\begin{init}| command is an abbreviation for
+\verb|\begin{schema}{\Init}|. Similarly \verb|\begin{state}|
+is a more meaningful synonym for \verb|\begin{schema*}|.
+
+You will be given \LaTeX\ warning messages if you try to
+use a \verb|state| environment outside of a class box
+or if you try to place an environment such as \verb|syntax|
+inside a class. You can ask for additional help in these
+cases using the normal \LaTeX\ \verb|h| or \verb|H| help commands.
+If you proceed with \LaTeX ing, the macros will attempt to
+do the best they can to do what you probably intend, even though
+you are violating the recommended nesting guidelines.
+
+\section{Controlling the Spacing within Equations and Boxes}
+
+Most of the special Z symbols are defined
+in a way that allows \TeX\ to space them out correctly.
+Sometimes, however, you'll need to give \TeX\ a helping hand if
+you want it to get the spacing right. For example, to get $map\,f$
+you need to type \verb|map\,f|. The \verb|\,| gives you a thin space:
+if this is omitted, the input \verb|map f| gives
+$map f$, because \TeX\ ignores spaces in math mode.
+
+Sometimes it is useful to indent the left margin to emphasis
+the logical structure of the predicate.
+The command \verb|\t1| does this by making the corresponding
+line in the output have one helping of indentation.
+As things get more nested, you can say \verb|\t2|, \verb|\t3|, and so on.
+But if you should ever get beyond \verb|t9|, you'll need to use braces
+around the argument: \verb|\t{10}|, and you'd better look for some way
+to simplify your specification!
+These little tab marks might look different to normal tabs
+but are never the less convenient. They're short,
+and they don't get longer as the tabbing gets deeper, within reason,
+so they can be tucked in neatly on the left, well away from the maths.
+The size of `helping' you get with \verb|\t| is determined by
+the \verb|\zedtab| parameter (see Section 7).
+
+If you want a more powerful aligning mechanism than tabbing
+then you can use the margin stack as shown in the example below.
+The command \verb|\M| sets the future left margin to the current
+horizontal position and pushes the old value onto a margin stack.
+The command \verb|\O| resets the left margin to its previous value
+(which is popped off the stack).
+
+\begin{example}
+\begin{schema}{Test}
+x, y : \nat
+\ST
+x + 1/x = 0 \imp \M y + 1/y = 0 \\
+y = x \O \\
+\end{schema}
+\end{example}
+
+If a schema or other box contains more than one predicate below the
+line, it often looks better to add a tiny vertical space between
+them, as in this example:
+
+\begin{example}
+\begin{schema}{AddBirthday}
+ \Delta BirthdayBook \\
+ n?: NAME \\
+ d?: DATE
+\ST
+ n? \nem known
+\also
+ birthday'=birthday \uni \{n? \map d?\}
+\end{schema}
+\end{example}
+
+This is done with the command \verb|\also|, which behaves syntactically
+like \verb|\ST|.
+The command \verb|\also| is provided {\em instead\/} of the
+optional argument to \verb|\\|
+which \LaTeX\ provides in other environments.
+If larger vertical spacing is required, the commands
+\verb|\Also| and \verb|\ALSO| may be used (giving 2 and 4 times
+as much space as \verb|\also| respectively).
+
+Normally, the contents of a schema box are kept on a single page.
+For large schemas it may be necessary to split the box across pages.
+You must specify which places are suitable for splitting using one of
+\verb|\zbreak|, \verb|\Zbreak| or \verb|\ZBREAK|. If no split is
+performed at this point, a vertical space will be added as if the
+user had typed \verb|\also|, \verb|\Also|, or \verb|\ALSO| respectively.
+You can also use the \verb|\znewpage| command to force a page break within
+a box. (These breaking facilities will hopefully never be needed for schemas,
+but may become necessary for class specifications.)
+
+\section{Other Display Environments}
+
+The \verb|zed| environment can be used to set multi-line formulas without
+an enclosing box: it is useful for given-set declarations, theorems, and the
+miscellaneous bits of mathematics that don't come in a box:
+
+\vspace{-1ex}\begin{example}
+\begin{zed}
+ \all n: \nat \dot \\
+\t1 n+n \mem even.
+\end{zed}
+\end{example}
+
+The formula \verb|\begin{zed} ... \end{zed}| may be abbreviated to
+\verb|\[ ... \]|; the \verb|zed| environment is a generalization of the
+\verb|displaymath| environment of \LaTeX, so this redefinition of
+commands is fairly benign. Notice that the maths is set flush left on the
+same indentation as schemas and their friends.
+Here too you can use \verb|\also| for a little extra space
+between lines.
+
+For algebraic-style proofs, there is the \verb|argue| environment.
+This is like the \verb|zed| environment, but the separation between
+lines is increased a little, and page breaks may occur between lines.
+When the left-hand side is long this style wastes less space
+than the \LaTeX\ \verb|eqnarray| style.
+The intended use is for arguments like this:
+\begin{argue}
+ rev(append(cons(x,s),t)) \\
+\t1 = rev(cons(x,append(s,t))) \\
+\t1 = append(rev(append(s,t)),cons(x,nil)) \\
+\t1 = append(append(rev(t),rev(s)),cons(x,nil))
+ \quad \hbox{by hypothesis} \\
+\t1 = append(rev(t),append(rev(s),cons(x,nil))) \\
+\t1 = append(rev(t),rev(cons(x,s))).
+\end{argue}
+Here is the input:
+\begin{quote}
+\begin{verbatim}
+\begin{argue}
+ rev(append(cons(x,s),t)) \\
+\t1 = rev(cons(x,append(s,t))) \\
+\t1 = append(rev(append(s,t)),cons(x,nil)) \\
+\t1 = append(append(rev(t),rev(s)),cons(x,nil))
+ \quad \hbox{by hypothesis} \\
+\t1 = append(rev(t),append(rev(s),cons(x,nil))) \\
+\t1 = append(rev(t),rev(cons(x,s))).
+\end{argue}
+\end{verbatim}
+\end{quote}
+
+The example below shows an inference rule (the optional argument
+to \verb|\derive| gives a side-condition of the rule):
+
+\vspace{-1ex}\begin{example}
+\begin{infrule}
+ \Gamma \shows P
+\derive[x \nem freevars(\Gamma)]
+ \Gamma \shows \all x \dot P
+\end{infrule}
+\end{example}
+
+The \verb|syntax| environment is used for making displays like this:
+
+\begin{syntax}
+ EXPR & \ddef & IDENT & identifier \\
+ & \bbar & EXPR\;EXPR & application \\
+ & \bbar & \lambda IDENT \dot EXPR & lambda-abstraction.
+\end{syntax}
+from input like this:
+\begin{quote}
+\begin{verbatim}
+\begin{syntax}
+ EXPR & \ddef & IDENT & identifier \\
+ & \bbar & EXPR\;EXPR & application \\
+ & \bbar & \lambda IDENT \dot EXPR & lambda-abstraction.
+\end{syntax}
+\end{verbatim}
+\end{quote}
+
+This kind of thing is useful when you're describing a language,
+and it can also be used for data-type definitions as shown below.
+The optional final column was omitted below by leaving out the third \verb|&|.
+
+\begin{example}
+\begin{syntax}
+TYPE & \ddef & givenT \lang NAME \rang \\
+& \bbar & powerT \lang TYPE \rang \\
+& \bbar & tupleT \lang \seq TYPE \rang \\
+& \bbar & schemaT \lang IDENT \ffun TYPE \rang \\
+& \bbar & classT \lang IDENT \ffun ClassAttr \rang
+\end{syntax}
+\end{example}
+
+This can be compared with the layout adopted by the UQ Z editor (version 1).
+
+\begin{example}
+\begin{zed}
+TYPE \ddef \M givenT \lang NAME \rang \\
+\bbar powerT \lang TYPE \rang \\
+\bbar tupleT \lang \seq TYPE \rang \\
+\bbar schemaT \lang IDENT \ffun TYPE \rang \\
+\bbar classT \lang IDENT \ffun ClassAttr \rang \O
+\end{zed}
+\end{example}
+
+The {\tt sidebyside} environment allows a display as shown in the
+first two columns below to be produced from the text of the third column.
+Note the use of the \verb|\comment| command.
+
+\begin{example}
+\begin{sidebyside}
+\begin{schema}{Schema}
+\comment*{declarations}
+\ST
+a < b \comment{pred-1} \\
+aaaaa < bbbbb \comment{pred-2}
+\end{schema}
+\nextside
+\begin{zpar}
+This is a paragraph which has the same
+margins as the standard schemas do.
+\end{zpar}
+\end{sidebyside}
+\end{example}
+
+In fact, this environment was used throughout this note to
+display the examples beside the required input text.
+Incidentally, the above example shows that \verb|sidebyside|
+environments can be nested; so what the author of this note typed
+to get the above display was:
+
+\begin{quote}
+\begin{verbatim}
+\begin{sidebyside}
+ \begin{sidebyside}
+ ...
+ \nextside
+ ...
+ \end{sidebyside}
+\nextside
+ ...
+\end{sidebyside}
+\end{verbatim}
+\end{quote}
+
+This resulted in the first two columns being equally spaced and
+together taking up as much space as the third column.
+You can have more than 2 columns without nesting by specifying an optional
+parameter to \verb|sidebyside|. For example, the display below has three
+equally spaced columns obtained using \verb|\begin{sidebyside}[3]|.
+
+ \begin{sidebyside}[3]
+ \begin{schema}{BirthdayBook}
+ known: \pset NAME \\
+ birthday: NAME \pfun DATE
+ \ST
+ known = \dom birthday
+ \end{schema}
+ \nextside
+ \begin{schema}{BirthdayBook}
+ known: \pset NAME \\
+ birthday: NAME \pfun DATE
+ \ST
+ known = \dom birthday
+ \end{schema}
+ \nextside
+ \begin{zpar}
+Don't get carried away with \verb|sidebyside|
+ like this example does.
+ \end{zpar}
+ \end{sidebyside}
+
+\section{Style Parameters}
+
+\begin{description}
+\item[\tt\string\zedindent] The (horizontal) indentation for mathematical text.
+ By default, this is the same as \verb|\leftmargini|, the indentation
+ used for list environments.
+\item[\tt\string\zedleftsep] The (horizontal) space between the vertical line on the left
+ of schemas, etc., and the maths inside. The default is 1em.
+\item[\tt\string\zedtab] The unit of indentation used by \verb|\t|. The default
+ is 2em.
+\item[\tt\string\zedbar] The length of the horizontal bar in the middle of a
+ schema. The default is 8em.
+\item[\tt\string\leftschemas] A declaration which makes schema names be
+ set flush left. Use it in the document preamble.
+\item[\tt\string\zedlinethickness] The thickness of the lines that make up
+ schema and class boxes. You can change the thickness
+ with a command such as \verb|\zedlinethickness=0.1pt|. This may
+ be useful if you are creating overhead slides.
+ \begin{description}
+ \makeatletter
+ \item[0.1pt] \zedlinethickness=0.1pt
+ ~\hbox to 4cm{\z@hrulefill}
+ \item[0.4pt] \zedlinethickness=0.4pt
+ ~\hbox to 4cm{\z@hrulefill}~~~(The default)
+ \item[\hphantom{0.}1pt] \zedlinethickness=1pt
+ ~\hbox to 4cm{\z@hrulefill}
+ \end{description}
+\item[\tt\string\baselinestretch] The spacing for the text part of your
+ document. It doesn't change the spacing within Z environments. It's
+ default value is 1. A command such as \verb|\def\baselinestretch{2}|
+ will make your text double spaced, but not your Z environments.
+\item[\tt\string\zedbaselinestretch] The spacing for the Z environment
+ part of your document. It's default value is 1.
+\item[\tt\string\zedsize] The size of the material within the Z
+ part of your document. It doesn't affect the remainder of your document.
+ For example, \verb|\zedsize{\large}| will give you large Z symbols
+ and equations but will not affect the size of the surrounding text.
+\item[\tt\string\zedcornerheight] The height of `corners' that can be placed
+ on the right hand side of the top and bottom lines of schema and class
+ boxes. The default is 0em (i.e. no corners).
+\end{description}
+
+\section{Symbols}
+
+Multi-letter identifiers have been changed to look
+better than they do with vanilla \LaTeX: instead of
+$\mathit{specifications}$, you get $specifications$.
+The letters haven't been spread apart, and the
+ligature $fi$ has been used.
+
+Almost all of the mathematical symbols of \LaTeX\ can be used;
+some have been redefined---usually to fix the spacing so that it is
+suitable for Z specifications.
+The commands for obtaining additional symbols are listed below.
+Sometimes more than one command may produce a symbol you
+require. You should use the one that seems to be designed for the
+context you have in mind. This is because the spacing around (and size of)
+symbols has been chosen for their typical context.
+
+Throughout the lifetime of these macros a number of alternate control
+sequences for any symbol may have existed. A list of aliases has been
+set up so that old commands may still be used. It is
+recommended however that you stick to the recommended command
+names for symbols as these names may be supported by other tools.
+Within the table below non-recommended aliases are surrounded by
+brackets, e.g., \verb|(\power)|.
