+___________________
+The PRACJOURN class
+
+This class file is used for typesetting articles in the PracTeX Journal
+(<http://tug.org/pracjourn>). It is based on the article class with 
+modifications to allow for more flexible front-matter and revision control, 
+among other small changes.
+
+It uses Palatino (12/15.5 pt) for the main text font, and Latin Modern Sans 
+and Typewriter for the companion fonts. It is not essential to have 
+the Latin Modern fonts installed, since the class file will fall back to 
+the older Computer Modern-based versions if necessary.
+
+_____
+USAGE
+
+No class options are necessary. \title, \author, and \abstract metadata is 
+required. Please see pracjourn.pdf for the full documentation.

+\maketitle
+
+\section{Introduction}
+This is an example of the \texttt{pracjourn} document class.
+Articles should always start with a section title, which will usually be `Introduction' or somesuch.
+
+This document demonstrates the features of the document class.
+Here are some logos and abbreviations:
+  \note{Tuned for Palatino, but refinements welcomed.}
+\TeX, \pdfTeX, \BibTeX, \MF, \MP, \LaTeX, \LaTeXe, 
+\mbox{\ConTeXt}, \pdfLaTeX, \XeTeX, \PracTeX, \TPJ, \PS.
+
+On the following pages are shown the document divisions and list environments.
+
+\newpage
+\section{Section headings}
+\itshape The fact is that his precocity in vice was awful. At five months of age he
+used to get into such passions that he was unable to articulate. At six
+months, I caught him gnawing a pack of cards. At seven months he was in
+the constant habit of catching and kissing the female babies. At eight
+months he peremptorily refused to put his signature to the Temperance
+pledge.
+  \note{Text from Edgar Allen Poe's `Never bet the Devil your head'.}
+
+\subsection{Subsection}
+
+Poverty was another vice which the peculiar physical deficiency of
+Dammit's mother had entailed upon her son. He was detestably poor, and
+this was the reason, no doubt, that his expletive expressions about
+betting, seldom took a pecuniary turn. I will not be bound to say that I
+ever heard him make use of such a figure of speech as ``I'll bet you a
+dollar.'' It was usually ``I'll bet you what you please,'' or ``I'll bet you
+what you dare,'' or ``I'll bet you a trifle,'' or else, more significantly
+still, \emph{``I'll bet the Devil my head.''}
+
+\subsubsection{Subsubsection}
+
+\upshape Subsubsections are in the same font size as the body text, so I guess
+it's possibly a little small. I doubt many people really will wish to
+use a subsubsection in a journal article. But if they wish, there's
+nothing stopping 'em.
+  \note{Another footnote test. 
+    This one has to be really long to see what happens 
+    when a footnote extends over more than one line. 
+    I.e., two or more.}
+
+\paragraph{Paragraphs} Named paragraphs are very similar to description lists; however, these may be useful more \emph{multiple} paragraphs, whereas description lists work better with only a single paragraph per item.
+
+\subparagraph{Subparagraphs} For those who want them\dots.
+
+\newpage
+\section{Lists}
+An itemized list:
+\begin{itemize}
+\item one,
+\item two, and
+\item three.
+  A nested itemised list:
+  \begin{itemise}
+  \item one,
+  \item two, and
+  \item three.
+  \end{itemise}
+\end{itemize}
+An enumerated list:
+\begin{enumerate}
+\item one,
+\item two, and
+\item three.
+\end{enumerate}
+A description list:
+\begin{description}
+\item [one] the first,
+\item [two] the second, and
+\item [three] the third. A nested description list:
+  \begin{description}
+  \item [one] the first,

+% \maketitle
+%
+% \begin{abstract}
+%   \noindent\textsf{pracjourn} is a class based on \texttt{article.cls}, 
+%   to be used for typesetting articles in The Prac\TeX\ Journal, 
+%   \url{http://tug.org/pracjourn}.
+% \end{abstract}
+%
+% \tableofcontents
+% 
+% \section{Introduction}
+%
+% The \pkg{pracjourn} \LaTeX{} document class is to be used for
+% articles written for the The Prac\TeX\ Journal,
+% \url{http://tug.org/pracjourn}.  The source for the document class
+% resides at \url{http://tug.org/pracjourn/dtx}, and is also
+% available at CTAN.
+%
+% \section{Usage}
+%
+% Refer to the sample document, \url{www.tug.org/pracjourn/dtx/pjsample.tex},
+% for context. Issue a |\documentclass{pracjourn}| command at
+% the beginning of your document as usual. No class options are necessary.
+%
+% This document class automatically loads the packages 
+% \pkg{color}, \pkg{graphicx}, \pkg{hyperref}, and \pkg{textcomp}. 
+% These are all standard packages in every \TeX\ distribution.
+%
+% \subsection{Formatting}
+%
+% Page metrics are appropriate for printing on either A4 or
+%   letter size paper. The type size is 12/15.5 Palatino. 
+% Except in exceptional circumstances, please refrain from 
+%   using typefaces other than those defined by this class.
+%
+% Hyperlinks are inserted automatically in the relevant locations in
+% a dark blue colour. If you wish to adjust this colour to suit your
+% own colour requirements, simply redefine the \texttt{linkcolour}. E.g.,
+% to change it to dark red,\\
+% \indent|\definecolor{linkcolour}{rgb}{0.7,0.2,0.2}|.
+%
+% \subsection{Author/article metadata}
+%
+% All author and article information must be defined before \cmd\maketitle, which 
+% should probably be the first thing after |\begin{document}|.
+% 
+% \DescribeMacro{\author}
+% \DescribeMacro{\title}
+% \DescribeMacro{\abstract}
+% The \cmd\author, \cmd\title, and \cmd\abstract\ commands are used to
+%   define those pieces of metadata about the article, and are mandatory.
+% Note that the \cmd\abstract\ is a plain old command, \emph{not} an environment.
+%
+% \DescribeMacro{\noabstract}
+% Should you have a reason for not having an abstract,
+%     this may be signified by declaring \cmd\noabstract\ instead.
+%
+% \DescribeMacro{\license}
+% It is optional to specify a copyright and/or license declaration, 
+%   to be typeset in the footer of the first page, with the \cmd\license\
+%   command.\footnote{The \cmd\TPJcopyright\ command, which used to provide this
+%   functionality is still provided for backwards compatibility.}
+%
+% \DescribeMacro{\email}
+% \DescribeMacro{\website}
+% \DescribeMacro{\address}
+% Additional author information may be specified, to be typeset appropriately,
+%   with the following commands: \cmd\email, \cmd\website, and \cmd\address.
+%   
+%   If the \pkg{switcheml} package is installed somewhere that
+%     \TeX\ will find it, it is loaded for the purpose of obfuscating
+%     the typeset email address. This is done to prevent harvesting by
+%     spammers, but if the package cannot be found the email address
+%     will by typeset as a hyperlink. 
+%
+% \DescribeMacro{\hyperlinkemail}
+%   Should you wish to typeset your
+%     email address as a hyperlink (that is, theoretically harvestable
+%     by spammers) despite having \pkg{switcheml} installed, you may
+%     simply include the command \cmd\hyperlinkemail\ anywhere before
+%     \verb|\begin{document}|.
+%
+% \subsubsection{Adding more author/article information}
+%
+% As previously
+% mentioned, this class provides the \cmd\email, \cmd\website, and \cmd\address\
+% macros for typesetting that information in the header block. These commands are defined 
+% in the source code of the class file with (something like) the following:\footnote{\cmd\typesetemail\ is an internal command defined by either \cmd\hyperlinkemail\ or \cmd\obfuscateemail.}
+% \begin{quote}
+%   |\addinfo[\typesetemail]{Email}|\\
+%   |\addinfo[\url]{Website}|\\
+%   |\addinfo{Address}|
+%  \end{quote}
+% Additional blocks my be added on a per-article basis in the same manner.
+%
+% \DescribeMacro{\addinfo}
+% To be specific, the \cmd\addinfo\ command takes one mandatory argument,
+% which is the title of the item to be added to the list, and one optional
+% argument, which is used to define the formatting of the block.
+%
+% This command will then define the macro used to input the additional information
+% by taking the lowercase of the title of the information and turning it into
+% a \TeX\ macro. This creates the obvious limitation on the name of the information
+% blocks that only single words may be used to describe any additional metadata. This
+% should not cause concern in practice.
+%
+% \DescribeMacro{\addinfospace}
+% If you wish to add some vertical space after the previous item in the front matter,
+% the \cmd\addinfospace\marg{height} command will insert some. This may be necessary
+% after multi-line blocks, which require some breathing room.
+%
+% \DescribeMacro{\clearinfo}
+% If you don't like the ordering of the information blocks or you wish to edit
+% the formatting of the current setup, the \cmd\clearinfo\ command allows you to start
+% fresh and redefine the address, email, and website information blocks however you may wish.
+%
+% \subsection{Additional user commands}
+% \DescribeMacro{\dash} For `smart' dashes in text. Thinly spaced from the text, it ignores surrounding spaces, and permits only succeeding line breaks.
+%   \begin{quote}
+%  |use like this \dash for consistent dashes|
+%   \end{quote}
+%   produces `use like this \unskip\thinspace\nobreak\textemdash\thinspace for consistent dashes'.
+%
+%
+% \DescribeMacro{\note} For easier footnotes. This command ignores preceding space, so linebreaks before the footnote text in the source will not give the wrong spacing.
+%   \begin{quote}
+%  |And here's an example.|\\
+%  |  \note{Albeit a trivial one.}|\\
+%  |And continuing|
+%   \end{quote}
+%   produces `And here's an example.
+%    \unskip\footnote{Albeit a trivial one.}
+%   And continuing'.
+%
+% \DescribeEnv{itemise} For non-US writers, it is probably more natural
+% to use |\begin{itemise}| over what \LaTeX\ provides by default.
+%
+% \DescribeMacro{\ctanfile}
+% \changes{v0.4j}{2006/02/09}{Implemented.}
+% \DescribeMacro{\ctanloc}
+% \changes{v0.4j}{2006/02/09}{Implemented.}
+% These commands are used to refer to online locations and documentation within the Comprehensive \TeX\ Archive Network. Usage is as follows:
+% \begin{quote}
+%   |\ctanfile{macros/latex/contrib/titlesec/titlesec.pdf}|\\
+%   |\ctanloc{macros/latex/contrib/titlesec/}|
+% \end{quote}
+% It will print the input prefixed with `CTAN:' and provide a hyperlink to the location.
+%
+% \subsection{TPJ internal commands}
+% 
+% Two commands are to be used at the direction of the Prac\TeX\
+%   production team: \cmd\TPJrevision\ and \cmd\TPJissue. These
+%   commands typeset information in the header of the first page
+%   relating to the revision number (or date) of the article and the
+%   issue number of the journal.
+% 
+% This document class creates a file \verb+_rev.tex+ in the
+%   current directory (if a \cmd\TPJrevision{} statement is present)
+%   and reads a file \verb+_iss.tex+, if present.  Please keep a
+%   separate directory for each article you develop for TPJ.

+% \section{History}
+%
+% The first revision of this class was written by Karl Berry.
+% KB: Gratefully based on the \texttt{dtxtut} skeleton.
+%
+% Revised by Arthur Ogawa, 2004/01/03, to include new features, per
+% Lance Carnes, as follows:
+%
+% \begin{enumerate}
+% \item Define an \cmd\articleID{} macro which typesets the article
+%   identification in a block somewhere on the first page of the
+%   article, and which can be used to identify the article/revision
+%   date for reader comments.  E.g. if this appears in the article
+%   source file:
+% \begin{verbatim}
+% \author{A.U. Thor}
+% \title{Pracjourn Sample}
+% \TPJissue{TPJ Vol 1 No 1, 2005-1-15}
+% \TPJrevision{2005-2-12}%
+% \TPJcopyright{\textcopyright\ 2005 TeX Users Group}
+% \end{verbatim}
+%   it will become a block of text typeset on the first page of the
+%   article.  See
+%   e.g. \href{http://www.ams.org/bull/2004-41-04/S0273-0979-04-01032-8/S0273-0979-04-01032-8.pdf}{this example PDF}.
+%
+% \item Write the information from the argument of the
+%   \cmd\articleID{} macro into a file called \verb+_id.tex+.  Put
+%   this file in the same directory as the source file, and overwrite
+%   any previous files of the same name.
+%
+% \item Define a \cmd\TPJcopyright{} macro which will print a
+%   copyright notice at the bottom of the first page.
+%   E.g. \cmd\TPJcopyright\verb+{2005 TeX Users Group}+ will produce
+%   ``\copyright2005 TeX Users Group'' in the page footer of the title
+%   page.
+%
+% \item The page measures should work with both Letter and A4 paper
+%   sizes.
+% \end{enumerate}
+%
+% Revised again by Will Robertson, mid-2005, to implement some
+% extra things. This snow-balled into the current version, a description
+% of which here would be redundant.
+%
+% \clearpage
+% \section{Implementation}
+%
+% The is fairly poorly documented, and the
+% class has undergone a multitude of small changes over the TPJ issues
+% 2005-4, 2006-1. It should now be fairly stable, and over time it's
+% conceivable (but unlikely) that the descriptions herein will be improved.
+%
+% \subsection{Base class and options}
+%
+% Use \LaTeX's \pkg{article} class, but at a bigger default type size.
+%
+% KB: 12pt seems a little too big, 11pt seems a little too small.
+% Implementing 11.5pt is not obvious.
+%
+% \changes{v0.3}{2004/01/03}{AO: Override the default option list of
+%   \pkg{article.cls}}
+%
+% If the document instance calls for options that conflict with the
+% following choices, then the document wins.  However our default
+% option list is not the same as those of \pkg{article.cls}.
+%    \begin{macrocode}
+\let\ExecuteOptions@ltx\ExecuteOptions
+\def\ExecuteOptions#1{%
+ \ExecuteOptions@ltx{letterpaper,12pt,oneside,onecolumn,final}%
+}%
+\LoadClassWithOptions{article}
+\let\ExecuteOptions\ExecuteOptions@ltx
+%    \end{macrocode}
+%
+% \subsection{Metrics}
+%
+% Default leading (from \texttt{classes.dtx}) for 11pt is 13.6pt
+% leading, for 12pt is 14.5pt.  We want more---this factor gives us
+% 12pt type on 15.5pt leading.
+%    \begin{macrocode}
+\linespread{1.069}
+%    \end{macrocode}
+% 
+% Change the text width to something that works for both A4 and
+% Letter paper, as well as possible.
+%
+% xx The vertical dimensions need to be changed as well, perhaps
+% for a 9in text height, taking account of the headline and
+% footline.
+%    \begin{macrocode}
+\setlength\textwidth{432pt}
+\setlength\oddsidemargin{18pt}% xx depend on letter/a4
+\setlength\evensidemargin{18pt}
+%    \end{macrocode}
+%
+% \subsection{Package loading}
+%
+% Palatino, including math (sc option for true small caps, not in TL
+% 2003).  Try for \pkg{mathpazo}; if not available use \pkg{palatino}.
+%
+% Enable pdf\TeX's margin kerning, if available, but \emph{not} font expansion,
+% which increases the size and complexity of the resultant PDF. This side-effect
+% may be deemed negligible in the future.
+%
+% \changes{v0.3}{2004/01/03}{AO: rewrite using \cs{IfFileExists} idiom.}
+% \changes{v0.4e}{2005/08/22}{WR: requires the textcomp package.}
+% \changes{v0.4g}{2005/11/04}{WR: use \pkg{microtype}, if available}
+%
+% The \pkg{textcomp} package is loaded in order to provide a nice looking copyright logo, amongst other things.
+%
+%    \begin{macrocode}
+\IfFileExists{mathpazo.sty}
+             {\RequirePackage[sc]{mathpazo}}
+             {\renewcommand\rmdefault{ppl}}
+\IfFileExists{microtype.sty}{\RequirePackage[protrusion=true,expansion=false]{microtype}}{}             
+\RequirePackage{textcomp}             
+%    \end{macrocode}
+% \pkg{hyperref} is used for creating live hyperlinks, as well as
+% providing \cmd\url\ for typesetting URLs easily. All hyperlinks
+% are coloured in a dark shade of blue.
+%    \begin{macrocode}
+\RequirePackage{color,hyperref,graphicx}
+\definecolor{linkcolour}{rgb}{0,0.2,0.6}
+\hypersetup{colorlinks,breaklinks,
+            linkcolor=linkcolour,citecolor=linkcolour,
+            filecolor=linkcolour, urlcolor=linkcolour}
+%    \end{macrocode}
+% If the \pkg{switcheml} package is installed in the author's
+% system, use it to obfuscate their email address by default. Otherwise, just
+% use a hyperlink. The commands to do this are defined in a later section.
+%
+% An author may specify \cmd\hyperlinkemail\ explicitly
+% should they not care to obfuscate their email address even with the \pkg{switcheml}
+% package installed.
+%    \begin{macrocode}
+\IfFileExists{switcheml.sty}
+             {\RequirePackage{switcheml}
+              \AtBeginDocument{\@ifx@undefined{\typesetemail}{\obfuscateemail}{}}}
+             {\AtBeginDocument{\@ifx@undefined{\typesetemail}{\hyperlinkemail}{}}}
+%    \end{macrocode}
+%
+%
+% \subsection{Amendments from \pkg{article}}
+%
+% \begin{macro}{\maketitle}
+% Printing the date of the last \TeX\ run in the title block does
+% not seem warranted---if someone reprocesses the document with no
+% changes, we wouldn't want the date to change.
+%
+% xx use rcs.sty or something?
+%
+% xx include bibtex id?
+%
+% \changes{v0.3}{2004/01/03}{AO: reproduce entire definition from

+% \end{macro}
+%
+% \begin{macro}{\clearinfo}
+% If the \cmd{\tpj@optional@author@info} macro needs to be cleared for some reason,\footnotemark
+% the \cmd\clearinfo\ command will come quite in handy. This command is also used to
+% initialise the macro in question.

+% \begin{macro}{\tpj@info@container}
+% This is the macro that typesets the optional author info for
+% fields defined as above. It splits it all up in minipages, in a
+% smaller font and with more compressed leading than the main
+% document text.\footnote{\LaTeX's \cmd\@hangfrom\ (or whatever it is) could well
+% have been much easier.} It takes the name of the info as a mandatory
+% argument, which is used to typeset the info label as well as
+% retrieve the actual data from the |\tpj@info@#1| macro (see
+% \cmd{\addinfo}).
+%
+% An optional argument is used as a hook to typeset the info data in
+% the equivalent form |#1{#2}|.
+%
+% For example, to typeset the info defined by the author in the
+% \cmd\abstract\ (recall, this is set up due to a corresponding
+% |\addinfo{Abstract}|---see above), input
+% |\tpj@info@container{Abstract}|. To typeset it, say, in italics,
+% it would be possible to write
+% |\tpj@info@container[\textit]{Abstract}|.

+% \subsubsection{Email \& hyperlink macros}
+%
+% \begin{macro}{\typesetemail}
+%
+% We define the macro \cmd\typesetemail\ to be used for self-explanatory purposes.
+% The class contains methods to define it in one of two ways.
+%
+% \begin{macro}{\hyperlinkemail}
+% 
+% The \cmd\hyperlinkemail\ command defines \cmd\typesetemail\ to use the \pkg{hyperref}
+% package's facilities to create a hyperlink email address in the output document.
+%
+% \begin{macro}{\obfuscateemail}
+% 
+% The \cmd\obfuscateemail\ command defines \cmd\typesetemail\ to use the \pkg{switcheml}
+% package's facilities to create a machine-obfuscated email address in the output 
+% document.\footnote{The \pkg{switcheml} package defines, among a couple of other things, a macro for
+% typesetting email addresses that obfuscates their representation in the PDF file,
+% ensuring protection against harvesting email addresses from web-public
+% PDF documents.}
+%
+%    \begin{macrocode}
+\newcommand\obfuscateemail{%
+  \def\typesetemail##1{\ttfamily\switchemail{##1}}}
+\newcommand\hyperlinkemail{%
+  \def\typesetemail##1{\ttfamily\tpj@compose@mailto{##1}{Re: PracTeX Journal article}{##1}}}
+%    \end{macrocode}  
+% \end{macro}\end{macro}\end{macro}
+%
+% \begin{macro}{\tpj@compose@mailto}
+%
+% This macro takes three arguments to typeset a mailto email
+% hyperlink. The |#1| takes the email address, |#2| takes the
+% default subject of the email, and |#3| is the text to appear in
+% the output as the hyperlink.
+%
+% All spaces in the hyperlink source are converted to |%20| to
+% accommodate Mac~OS~X's PDF reader; this isn't necessary for Adobe
+% Reader. Oh well.
+%
+% \changes{v0.4b}{2005/06/26}{WR: Implemented; creates a workable mailto
+%   hyperlink.}
+%
+%    \begin{macrocode}
+\newcommand\tpj@compose@mailto[3]{%
+  \edef\@tempa{mailto:#1?subject=#2 }%
+  \edef\@tempb{\expandafter\html@spaces\@tempa\@empty}%
+  \href{\@tempb}{#3}}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\html@spaces}
+% \changes{v0.4b}{2005/06/25}{WR: Implemented to overcome the mailto
+%   problems in Mac~OS~X's PDF reader.}  
+
+% This macro takes a string and (hopefully) converts all spaces (or
+% is it all whitespace?) to `\%20', creating a string that can be
+% used for encoding the subject of the email comments hyperlink in
+% \cmd{\titlepage@head}. Using \cmd\catcode, we remove the comment
+% ability of the \verb|%| character, making it a normal letter.
+% (This code was heavily influenced by the \LaTeX\ kernel's
+% \cmd{\zap@space} command.)
+%    \begin{macrocode}
+\catcode`\%=11
+\def\html@spaces#1 #2{#1%20\ifx#2\@empty\else\expandafter\html@spaces\fi#2} 
+\catcode`\%=14

+%
+% \subsubsection{User commands}
+% 
+% \begin{macro}{\note}
+% \begin{macro}{\dash}
+% \begin{macro}{\ctanfile}
+% \begin{macro}{\ctanloc}
+% Fairly straightforward.

+% \subsubsection{Logos}
+%
+% \changes{v0.4a}{2005/06/05}{WR: Incorporated code from \pkg{texnames}
+%   and \pkg{mflogo}.}
+%
+% The \pkg{texnames} and \pkg{mflogo} packages have been incorporated
+% into the class in order to remove the dependence on external
+% packages and to tune the logos for Palatino. First, here are the
+% relevant parts\footnote{No-one still refers to AMSTeX and SLITeX and
+%   so on, right?} of \texttt{texnames.sty}, v1.10, tuned for Palatino
+% and adapted to use \cs{textsc} where appropriate:
+%    \begin{macrocode}
+\DeclareRobustCommand\TeX{T\kern-.15em\lower.5ex\hbox{E}\kern-.07em X\spacefactor1000\relax}
+\DeclareRobustCommand\LaTeX{L\kern-.32em\raise.37ex\hbox{\scalebox{0.76}{A}}\kern-.15em\TeX}
+\DeclareRobustCommand\LaTeXe{\LaTeX2$_{\textstyle\varepsilon}$}
+\DeclareRobustCommand\BibTeX{B{\textsc i\kern-.025em\textsc b}\kern-.08em\TeX}
+%    \end{macrocode}
+% And now \texttt{mflogo.sty}, unchanged in its entirety:
+%    \begin{macrocode}
+\DeclareRobustCommand\logofamily{%
+  \not@math@alphabet\logofamily\relax
+  \fontencoding{U}\fontfamily{logo}\selectfont}
+\DeclareTextFontCommand{\textlogo}{\logofamily}
+\DeclareRobustCommand\MF{\textlogo{META}\@dischyph\textlogo{FONT}\@}
+\DeclareRobustCommand\MP{\textlogo{META}\@dischyph\textlogo{POST}\@}
+%    \end{macrocode}
+% Now some new definitions. Despite the fact that it makes no
+% difference with the main font used for this class, I define
+% \cs{pdfTeX} with some italic correction to set a good
+% precedent. Compare Computer Modern with and without:
+% {\usefont{OT1}{cmr}{m}{n}pdf\/\TeX}
+% vs.~{\usefont{OT1}{cmr}{m}{n}pdf\TeX}; I find the former more
+% attractive because the ascender of the `f' doesn't collide.
+%    \begin{macrocode}
+\DeclareRobustCommand\ConTeXt{C\kern-.03em on\-\kern-.10em\TeX\kern-0.04em t}%
+\DeclareRobustCommand\pdfTeX{pdf\/\TeX}

+\DeclareRobustCommand\ExTeX{\textrm{\relax
+ \ensuremath{\textstyle\varepsilon_{\kern-0.15em\mathcal{X}}}\relax

+%    \end{macrocode}
