+\section{Introduction}
+
+This program has been written in frustration because some constructs in
+\LaTeX\ are sometimes non-intuitive, and easy to forget. It is
+\emph{not} a replacement for the built-in checker in \LaTeX\@; however it
+catches some typographic errors \LaTeX\ oversees. In other words, it
+is Lint for \LaTeX. Filters are also provided for checking the
+\LaTeX\ parts of CWEB documents.
+
+It is written in ANSI C and compiles silently under GCC using
+\Cmd{-Wall -ansi -pedantic} and almost all warning flags. This means
+that you can compile \& use the program on your favorite machine.
+Full source included.
+
+The program also supports output formats suitable for further
+processing by editors or other programs, making errors easy to cycle through.
+For example, recent versions of AUC\TeX\ (the Emacs mode) interface
+beautifully with \chktex.
+
+The program itself does not have any machine requirements; However compiling
+for other platforms has not been done for a long time now so the code has been
+removed. If interest rises it can be resurrected.
+
+
+\section{Features}
+\chktex\ begins to get quite a few bells \& whistles now. However, you
+should be aware of that in most cases, all this is transparent to the user.
+As you will see, \chktex\ offers the ability to adapt to many environments
+and configurations.
+
+\begin{itemize}
+\item Supports over 40 warnings. Warnings include:
+%latex
+ \begin{multicols}{2}
+ \begin{flushleft}
+%endlatex
+ \begin{itemize}
+ \item Commands terminated with space. Ignores \Cmd{\BS{}tt}, etc.
+ \item Space in front of references instead of \Cmd{\~{}}.
+ \item Forgetting to group parenthesis characters when
+ sub-\slash{}super\-scripting.
+ \item Italic correction (\Cmd{\BS/}) mistakes (double,
+ missing, unnecessary).
+ \item Parenthesis and environment matching.
+ \item Ellipsis detection; also checks whether to use
+ \Cmd{\BS{}dots}, \Cmd{\BS{}cdots} or \Cmd{\BS{}ldots}.
+ \item Enforcement of normal space after abbreviation. Detects
+ most abbreviations automagically.
+ \item Enforcement of end-of-sentence space when the last
+ sentence ended with capital letter.
+ \item Math-mode on/off detection.
+ \item Quote checking, both wrong types (\Cmd{"}) and wrong
+ direction.
+ \item Recommends splitting three quotes in a row.
+ \item Searching for user patterns.
+ \item Displays comments.
+ \item Space in front of \Cmd{\BS{}label} and similar commands.
+ \item Use of \Cmd{x} instead of \Cmd{\$\BS{}times\$} between numbers.
+ \item Multiple spaces in input which will be rendered as one
+ space (or multiple spaces, where that is undesirable).
+ \item Warns about text which may be ignored.
+ \item Mathematical operators typeset as variables.
+ \item No space in front of/after parenthesis.
+ \item Demands a consistent quote style.
+ \item Punctuation inside inner math mode/outside display math
+ mode.
+ \item Use of \TeX\ primitives where \LaTeX\ equivalents are
+ available.
+ \item Space in front of footnotes.
+ \item Bogus characters following commands.
+ \item Ability to suppress warnings on a single line.
+ \end{itemize}
+%latex
+ \end{flushleft}
+ \end{multicols}
+%endlatex
+\item Fully customizable. Intelligent resource format makes it
+ possible to make \chktex\ respect your \LaTeX\ setup. Even
+ command-line options may be specified globally in the \rsrc\ file.
+\item Supports \Cmd{\BS{}input} command; both \TeX\ and \LaTeX\ version.
+ Actually includes the files. \Cmd{TEXINPUTS}-equivalent search path.
+\item Intelligent warning/error handling. The user may promote/mute
+ warnings to suit his preferences. You may also mute warnings in the
+ header of a file; thus killing much unwanted garbage.
+\item Scripts included for checking CWEB files written in \LaTeX.
+ (Requires perl v5).
+\item Supports both \LaTeX\ 2.09 and \LaTeXe{}.
+\item Flexible output handling. Has some predefined formats and lets
+ the user specify his own format. Uses a \Cmd{printf()} similar
+ syntax. \Cmd{lacheck} compatible mode included for interfacing with
+ systems which only support lacheck.
+\item Written in ANSI C\@. \Cmd{configure} script included for easy
+ setup and installation on UNIX systems.
+\end{itemize}
+
+Still, it is important to realize that the output from \chktex\ is
+only intended as a \emph{guide} to fixing faults. However, it is by
+no means always correct. This means that correct \LaTeX\ code may
+produce errors in \chktex, and vice versa: Incorrect \LaTeX\ code may pass
+silently through.
+
+

+\section{Availability}
+
+This program is on CTAN\@; thus it can be found at any mirrors of those.
+It is also part of TeX Live 2011.
+
+\section{Installation}
+
+A few words on installation on various platforms:
+
+\begin{description}
+\item[UNIX:] Type \Cmd{configure}, \Cmd{make} and finally
+ \Cmd{make~install}. To make sure everything proceeded correctly,
+ type \Cmd{make~check}. If you don't have superuser privileges and thus
+ access to the default system areas, you should type
+ \Cmd{configure~-{}-help} to help you set up correct paths.
+
+ If you haven't installed any software like this before, that is
+ distributed in source form, here are some guidelines to help you
+ install it locally at your account. Please note that a mail to the
+ system administrator may be less work for you.
+
+ We assume that you have put the archive (\Cmd{chktex.tar.gz}) in a
+ subdir of yours, with path \Cmd{\~{}/tmp}. We further assume that
+ your shell is \Cmd{csh} or \Cmd{tcsh}. Do the following:
+
+ \begin{enumerate}
+ \item First of all, unpack the archive contents.
+
+\begin{verbatim}
+> cd ~/tmp
+> gunzip chktex.tar.gz
+> tar xf chktex.tar
+\end{verbatim}
+
+ \item Now, we can configure the program. There are some
+ configuration options you should know about:
+ \begin{description}
+ \item[\Cmd{-{}-enable-pcre}:] Allows using PCRE (perl compatible
+ regular expressions) for use defined warnings. The default is
+ to use PCRE if it is installed on your system as determined by
+ \Cmd{pcre-config}. You can use \Cmd{-{}-disable-pcre} if you
+ plan to distribute this for systems in which you cannot ensure
+ PCRE will be installed.
+
+ User defined regular expressions are defined using
+ \texttt{UserWarnRegex} in the \rsrc\ file. See warning~44 for
+ more information.
+
+ \item[\Cmd{-{}-enable-lacheck-replace}] This enables a quick
+ hack for using \chktex\ instead of lacheck. This is done by
+ installing a stub script which ``overrides'' the original
+ lacheck executable. In this way, tools which support lacheck
+ can be easily made to support chktex instead.
+
+ \item[\Cmd{-{}-enable-debug-info}] \chktex\ has an ability to spit
+ out various diagnostic messages using the \Cmd{-d} flag. This
+ behaviour is on by default. By adding the flag
+ \Cmd{-{}-disable-debug-info} to the commandline, this will not be
+ compiled in.
+
+ This may be useful if you're running short of disk space (the
+ time savings are neglible).
+ \end{description}
+
+ If you are installing the program on your local account, use the
+ following command:
+
+\begin{verbatim}
+> configure --prefix ~/
+\end{verbatim}
+
+ Add eventual extra flags as specified above. This command will
+ generate a significant amount of output, this can usually be ignored.
+
+ \item Finally, we can just build the program and install it.
+
+\begin{verbatim}
+> make
+> make install
+\end{verbatim}
+
+ \item Finished! The program is now installed and ready to use. You
+ may now tell other people to put your bindir in their path in
+ order to benefit from your work. All that remains is to make the
+ shell aware of your installation.
+
+\begin{verbatim}
+> rehash
+\end{verbatim}
+
+ To make the remaining parts of your system aware of this, you'll
+ have to log out and re-log in, I'm afraid. However, you should delay this
+ until you've completed this installation procedure.
+
+ \item If you wish to make sure that everything is OK (you ought to),
+ you may now ask \chktex\ to do a self-test:
+
+\begin{verbatim}
+> make check
+\end{verbatim}
+
+ \end{enumerate}
+
+\item[Other platforms:] First of all, you have to copy the
+ \Cmd{config.h.in} file to a file named \Cmd{config.h}. Then, edit
+ it to reflect your system. Do the same with \Cmd{OpSys.h} (this
+ file has been reduced significantly). If you wish, you may define
+ \Cmd{DATADIR} to the path you want the global resource file to be
+ put.
+
+ Now, I would suggest that you take a peak at the \Cmd{OpSys.c}
+ file, and edit it appropiately, for more
+ comfort. This should not be necessary, though, at least not the
+ first time.
+
+ Finally, you may now compile and link all \verb@.c@ files. Do not
+ forget to define \Cmd{HAVE\_CONFIG\_H} to 1 (on the command-line,
+ for instance). If the \Cmd{config.h} you wish to use has another
+ name, define \Cmd{CONFIG\_H\_NAME} to that (in that case, don't
+ define \Cmd{HAVE\_CONFIG\_H}).
+
+ Put the directory path of the \rsrc\ file in a environment variable
+ named \Cmd{CHKTEXRC}. The files \Cmd{deweb.in} and \Cmd{chkweb}
+ should be moved to a directory in your path. These files may need
+ further setup, as they haven't got the location of perl
+ initialized.
+
+ If your compiler/the compiled program complains (or crashes!), you
+ may try the hints listed below. Please note that it only makes
+ sense to try these hints if your compiler fails to produce a working
+ program.
+
+ \begin{enumerate}
+ \item Increase the preprocessor buffers and line buffers. The
+ \chktex{} sources define macros sized 3--4k (expanding to about
+ the same), and passes arguments sized about 1k.
+ \item Use the magic switch which lets us use large
+ \Cmd{switch(\dots)\{\dots\}} statements; some of these statements
+ have about 120 \Cmd{case} entries.
+ \item The sources require that at least the first 12 of each
+ identifier is significant.
+ \end{enumerate}
+\end{description}
+\paragraph{Note:} You \emph{must} install the new \rsrc\ file; \chktex\ will
+fail to function otherwise!
+
+ After doing this, you may enhance \chktex' behaviour by
+reading/editing the \rsrc\ file.

+\section{Usage}
+
+\subsection{\chktex}
+
+\subsubsection{Synopsis}
+
+A UNIX-compliant template format follows:
+
+\newcommand{\Group}[1]{\mbox{[#1]}}
+\begin{tabularx}{.95\linewidth}{lY}
+ \texttt{chktex} & \ttfamily \Group{-hiqrW} \Group{-v[0-\dots]} \Group{-l
+ <rcfile>} \Group{-[wemn] <[1-42]|all>} \Group{-d[0-\ldots]} \Group{-p
+ <pseudoname>} \Group{-o <outputfile>} \Group{-[btxgI][0|1]}
+ file1 file2 \dots
+\end{tabularx}
+
+
+\subsubsection{Options}
+
+These are the options \chktex\ currently accepts.
+Please note that single-lettered options requiring a numerical or no
+argument may be concatenated. E.g.\ saying \Cmd{-v0qb0w2} is the
+same as saying \Cmd{-v0~-q~-b0~-w2}, except for being less to
+type.
+
+Enough general talk; here's a rather detailed description of all
+options:
+\begin{description}
+\item[Misc.\ options:] General options which aren't related to some
+ specific subpart of \chktex.
+ \begin{description}
+ \item[\texttt{-h [-{}-help]}] Gives you a command summary.
+ \item[\texttt{-i [-{}-license]}] Shows distribution information.
+ \item[\texttt{-l [-{}-localrc]}] Reads a resource-file formatted
+ as the global resource-file \rsrc, in addition to the global
+ resource-file. This option needs the name of the resource-file
+ as a parameter. See also \texttt{-g}.
+ \item[\texttt{-r [-{}-reset]}] This will reset all settings to their
+ defaults. This may be useful if you use the \texttt{CMDLINE}
+ directive in your \rsrc\ file, and wish to do something
+ unusual.
+ \item[\texttt{-d [-{}-debug]}] Needs a numeric argument; a bitmask
+ telling what to output. The values below may be added in order
+ to output multiple debugging info.
+
+ \begin{tabularx}\linewidth{cX}
+ \bf Value & \bf Dumps\ldots\\
+ 1 & All warnings available and their current status. \\
+ 2 & Statistics for all lists in the resource file. \\
+ 4 & The contents of all lists in the resource file. \\
+ 8 & Misc.\ other status information. \\
+ 16 & Run-time info (note that this isn't widely used). \\
+ \end{tabularx}
+ The info is produced after all switches and resource files have
+ been processed.
+
+ It is possible to install versions of \chktex\ that ignore this
+ flag; this means that it is not certain that this flag works.
+ \item[\texttt{-W [-{}-version]}] Displays version information, and exits.
+ \end{description}
+\item[Muting warning messages:] Controls whether and in what form
+ error messages will appear. Usually they accept a specific warning
+ number (e.g.\ \Cmd{-w2}), but you may also say \Cmd{all} (e.g.\
+ \Cmd{-wall}) which does the operation on \emph{all} warnings.
+ \begin{description}
+ \item[\texttt{-w [-{}-warnon]}] Makes the message number passed as
+ parameter a warning and turns it on.
+ \item[\texttt{-e [-{}-erroron]}] Makes the message number passed as
+ parameter an error and turns it on.
+ \item[\texttt{-m [-{}-msgon]}] Makes the message number passed as
+ parameter a message and turns it on. Messages are not counted.
+ \item[\texttt{-n [-{}-nowarn]}] Turns the warning/error number passed
+ as a parameter off.
+ \item[\texttt{-L [-{}-nolinesupp]}] Turns off suppression of messages
+ on a per line basis. This is meant to be used to ensure that no new
+ errors have crept into a document while editing.
+ \end{description}
+\item[Output control flags:] Determines the appearance and
+ destination of the error reports.
+ \begin{description}
+ \item[\texttt{-q [-{}-quiet]}] Shuts up about copyright information.
+ \item[\texttt{-o [-{}-output]}] Normally, all errors are piped to \texttt{stdout}.
+ Using this option with a parameter, errors will be sent to the
+ named file instead. Only information relative to the \LaTeX\ file
+ will be sent to that file. Memory problems and similar will as as
+ always be sent to \texttt{stderr}. If a file with the name given
+ already exists, it will be renamed to \Cmd{foobar.bak}
+ (\Cmd{foobar.\$cl} under MS-DOS), \Cmd{foobar} being the name of
+ the file. See also \Cmd{-b}.
+
+ \item[\texttt{-v [-{}-verbosity]}] Specifies how much and how you
+ wish the error reports to be displayed. This is specified in the
+ \rsrc\ file; we'll list the default values below. If you wish,
+ you may thus edit the \rsrc\ file to add or modify new formats.
+
+ The default is mode 1 (that is, the \emph{second} entry in the
+ \rsrc\ file), using \texttt{-v} without any parameter will give you
+ mode 2.
+
+ \begin{description}
+ \item[0] Will show the information in a way that should be
+ suitable for further parsing by \texttt{awk}, \texttt{sed} or
+ similar. The format is as follows:
+\begin{verbatim}
+File:Line:Column:Warning number:Warning message
+\end{verbatim}
+ The colons may be replaced with another string; use the
+ \verb@-s@ switch for this.
+
+ As the program does not output all errors in quite order, this
+ output format is also suitable for piping through \Cmd{sort}.
+ \item[1] Shows the information in a way which is more
+ comprehensible for humans, but which still doesn't need
+ anything but a glass tty.
+ \item[2] Shows the information in a fancy way, using escape
+ codes and stuff. It is the indeed most readable of all
+ modes; however, it needs proper set up of the \Cmd{ChkTeX.h}
+ at compilation time. UNIX boxes, however, will find the
+ information automatically.
+ \item[3] Shows the information suitable for parsing by Emacs;
+ this is the same format as \texttt{lacheck} uses. More formally,
+ it is the following:
+\begin{verbatim}
+"File", line Line: Warning message
+\end{verbatim}
+
+ To utilize this, type \verb@M-x compile RET@. Delete whatever
+ is written in the minibuffer, and type
+ \verb@chktex -v3 texfile.tex@, and you should be able to
+ browse through the
+ error messages. Use \verb@C-x `@ to parse the messages.
+ \item[4] More or less the same as \verb@-v3@, but also includes
+ information on where the error actually was found. Takes somewhat
+ longer time to parse, but much more informative in use.
+ \end{description}
+
+ \item[\texttt{-f [-{}-format]}] Specifies the format of the output.
+ This is done using a format similar to \Cmd{printf()}, where we
+ support the specifiers listed below.
+
+ \smallskip
+ \newcommand{\Pf}[1]{\texttt{\%#1} &}
+ \begin{tabularx}{\linewidth}{cX}
+ \bf Code & \bf Description \\
+ \Pf{b} String to print \textbf{b}etween fields (from \texttt{-s}
+ option).\\
+ \Pf{c} \textbf{C}olumn position of error. \\
+ \Pf{d} Length of error (\textbf{d}igit). \\
+ \Pf{f} Current \textbf{f}ilename.\\
+ \Pf{i} Turn on \textbf{i}nverse printing mode.\\
+ \Pf{I} Turn off \textbf{i}nverse printing mode.\\
+ \Pf{k} \textbf{k}ind of error (warning, error, message).\\
+ \Pf{l} \textbf{l}ine number of error.\\
+ \Pf{m} Warning \textbf{m}essage.\\
+ \Pf{n} Warning \textbf{n}umber.\\
+ \Pf{u} An \textbf{u}nderlining line (like the one which
+ appears when using \Cmd{-v1}).\\
+ \Pf{r} Part of line in front of error ($\mbox{`S'} -
+ 1$).\\
+ \Pf{s} Part of line which contains error (\textbf{s}tring).\\
+ \Pf{t} Part of line after error ($\mbox{`S'} + 1$).
+ \end{tabularx}
+ \smallskip
+
+ Other characters will be passed literally; thus you can say
+ \Cmd{\%\%} to achieve a single percent sign in the output.
+ Please note that we may introduce other specifiers in the future,
+ so don't abuse this feature for other characters.
+
+ Also, note that we do \emph{not} support field lengths (yet).
+ This may come in the future, if I get the time\dots
+
+ The \texttt{-v} command is implemented by indexing into the \rsrc\
+ file; read that for seeing how each format is implemented. If
+ you find yourself using a particular format often by using the
+ -f switch, consider putting it in the \rsrc\ file instead.
+ \item[\texttt{-V [-{}-pipeverb]}] Which entry we'll use in the \rsrc\
+ file whenever \texttt{stdout} isn't a terminal.
+
+ The default is to use the same mode as specified with the
+ \texttt{-v} switch; using \texttt{-V} without any parameter will give you
+ mode 1.
+
+ This switch was implemented because GNU less has problems with
+ the escape codes \chktex\ uses for displaying inverse text.
+ Under UNIX, there's another way around, though, which is slightly
+ more elegant. Add the following line to your \Cmd{.envir} file:
+\begin{verbatim}
+setenv LESS -r
+\end{verbatim}
+
+ \item[\texttt{-p [-{}-pseudoname]}] With this switch, you can provide
+ the filename which will be used when we report the errors. This
+ may be useful in scripts, especially when doing pipes. It is in
+ other words similar to C's \verb@#line@ directive.
+
+ We will only assume this name for the uppermost file; files that
+ this one in turn \verb@\@\verb@input@ are presented under their original
+ names. This seems most logical to me.
+
+ \item[\texttt{-s [-{}-splitchar]}] String to use instead of the
+ colons when doing \texttt{-v0}; e.g.\ this string will be output
+ between the fields.
+
+ \end{description}
+\item[Boolean switches:] Common for all of these are that they
+ take an optional parameter. If it is \texttt{0}, the feature will
+ be disabled, if it is \texttt{1}, it will be enabled. All these
+ features are on by default; and are toggled if you don't give
+ any parameter.
+
+ \begin{description}
+ \item[\texttt{-b [-{}-backup]}] If you use the \texttt{-o} switch, and the
+ named outputfile exists, it will be renamed to \texttt{filename.bak}.
+ \item[\texttt{-I [-{}-inputfiles]}] Execute \verb@\@\verb@input@
+ statements; e.g.\ include the file in the input. Our input parsing
+ does of course nest; we use an input-stack to keep track of this.
+ \item[\texttt{-H [-{}-headererr]}] Show errors found in front of the
+ \verb@\begin{document}@ line. Some people keep \emph{lots} of
+ pure \TeX\ code there, which errors can't be detected reliably
+ (in other words, we will in most cases just produce a lot of
+ garbage).
+ \item[\texttt{-g [-{}-globalrc]}] Read in the global resource file. This
+ switch may be useful together with the \texttt{-l} option.
+ \item[\texttt{-t [-{}-tictoc]}] Display a twirling baton, to show that
+ we're working. \texttt{-v0} does an \texttt{-t0}, too, as it assumes
+ that the user then uses the program non-interactively. This is
+ now a no-op.
+ \item[\texttt{-x [-{}-wipeverb]}] Ignore the ``\verb@\verb@'' command
+ found within the \LaTeX\ file and its argument is completely by
+ the checking routines. This is done by simply overwriting them.
+ If you somehow don't like that (for instance, you would like to
+ count brackets inside those commands, too), use this switch.
+ \end{description}
+\end{description}
+
+
+If you don't specify any input \LaTeX-files on the commandline, we'll
+read from \texttt{stdin}. To abort \texttt{stdin} input, press the
+following keycombinations:
+
+\smallskip
+\begin{tabular}{ll}
+ \bf Machine & \bf Key-combination \\
+ UNIX & $\fbox{\texttt{Ctrl}} + \fbox{\texttt{D}}$ \\
+ MS-DOS & $\fbox{\texttt{Ctrl}} + \fbox{Z}$, followed by return.
+\end{tabular}
+\smallskip
+
+By default, we use GNU's \Cmd{getopt()} routine.
+
+\begin{itemize}
+\item Options may be given in any order; the names of the \LaTeX-files
+ do not have to be the last arguments. This behaviour may be turned
+ off by creating an environment variable named \Cmd{POSIXLY\_CORRECT}.
+\item The special argument \Cmd{-{}-} forces an end of
+ option-scanning.
+\item Long-named options begin with \Cmd{-{}-} instead of \Cmd{-}.
+ Their names may be abbreviated as long as the abbreviation is unique
+ or is an exact match for some defined option. If they have an
+ argument, it follows the option name in the argument, separated from
+ the option name by a \Cmd{=}, or else the in next argument.
+\end{itemize}
+
+\subsubsection{The \rsrc\ file}
+
+You should also take a look at the \rsrc\ file. As it is
+self-documenting, you should be able to get the meaning of each
+keyword by simply reading the file. In fact, since not all options
+are described in this documentation it is necessary that you read
+the \rsrc\ file in order to understand them all. The method for
+\emph{finding it} has grown rather complex. An outline is given below.
+
+If \chktex\ finds multiple files when searching, each and every one
+will be read in the order specified below. The \Cmd{Keyword = \{ item
+ item \dots \}} may thus be necessary to reset previously defined
+lists.
+
+In this list, \Cmd{\$foo} is assumed to be the environment variable
+\Cmd{foo}:
+
+\begin{enumerate}
+\item First, we'll take a look at the directory which was specified as
+ \Cmd{DATADIR} during compilation. On UNIX boxes, this usually
+ evaluates to something similar to
+ \Cmd{/usr/local/share/chktexrc}, under MS-DOS it is set
+ to \Cmd{\BS{}emtex\BS{}data\BS{}chktexrc}.
+
+\item Look in the following system directories:
+
+ \begin{tabular}{ll}
+ \bf Machine & \bf Directory \\
+ UNIX & \Cmd{\$HOME/.chktexrc} or \Cmd{\$LOGDIR/.chktexrc} \\
+ MSDOS & Program installation path
+ \end{tabular}
+
+\item Look for it in the directory pointed to by an environment
+ variable, as specified in the table below:
+
+ \begin{tabularx}\linewidth{lY}
+ \bf Machine & \bf Directory \\
+ UNIX & \Cmd{\$CHKTEXRC/.chktexrc} \\
+ MSDOS & \Cmd{\$CHKTEXRC\BS{}chktexrc}, \Cmd{\$CHKTEX\_HOME\BS
+ chktexrc} or \Cmd{\$EMTEXDIR\BS{}data\BS{}chktexrc}
+ \end{tabularx}
+
+\item Look for it in the current directory. On UNIX boxes,
+ we expect the filename to be \Cmd{.chktexrc}; on other machines
+ \Cmd{chktexrc}.
+
+\end{enumerate}
+
+If you for some reason wish to undo what the previous files may have
+done, you may say \Cmd{CmdLine \{ -g0 -r \}} somewhere in the \rsrc\
+file; this will reset all previous settings.
+
+\subsubsection{Per Line and File Suppressions}
+
+There are many cases in which \chktex{} will give a warning about a
+construct which, although it usually indicates a mistake, is
+intentional. In these cases it can be extremely annoying to have
+this message appear everytime \chktex{} is run. For this reason you
+can use \LaTeX{} comments to suppress a certain message on a single
+line. This can be done by adding a (case-insensitive) comment at the
+end of the line of the form
+\begin{center}
+ \verb+% chktex ##+
+\end{center}
+where \verb+##+ is the number of the message to be suppressed.
+For example the line
+\begin{center}
+ \verb+$[0,\infty)$+\\*
+\end{center}
+will produce a warning (number 9) about mismatched \verb+]+ and \verb+)+.
+However the lines
+\begin{center}
+ \verb+$[0,\infty)$ % chktex 9+\\*
+ \verb+$[0,\infty)$ % ChkTeX 9+\\*
+\end{center}
+will not produce such a message. In this case, message number 17 will
+still appear at the end, stating that the numbers of \verb+]+ and
+\verb+)+ don't match for the entire file.
+
+To suppress two different errors on the same line you will need two
+instances of \verb+chktex+ in the comment. This format is a little
+cumbersome, but it shouldn't be needed often, and hopefully will help
+avoid accidental suppressions.
+\begin{center}
+ \verb+Jordan--H\"older on $[0,\infty)$ % chktex 8 chktex 9+\\*
+\end{center}
+
+One problem inherent in line-by-line suppressions is that during editing
+another error of the same type may creep into the same line. Therefore,
+I suggest using the \texttt{-L} or \texttt{-{}-nolinesupp} option to
+disallow line based suppressions once just before the document is finished.
+At that point you should go back over all the warnings and decide if they
+should be fixed.
+
+In addition to line-specific suppressions, you can create a suppression which will be in effect for the remainder of the file.
+This can be used, for example, to turn off warning 18 (about \verb+"+) in a file which uses a package (like \Cmd{babel}) where \verb+"+ is an active character.
+The syntax is nearly the same, namely
+\begin{center}
+ \verb+% chktex-file ##+
+\end{center}
+
+\subsubsection{Hints}
+I've tried to collect some advice that may be useful --- if you have a
+favourite hint, feel free to send it to me!
+
+\begin{itemize}
+\item If you use \Cmd{german.sty} or several of \Cmd{babel} languages
+ which use \verb+"+ as an active character; it may be wise to put \Cmd{-n18} in
+ the \Cmd{CmdLine} entry in the \rsrc\ file. This will probably reduce
+ the amount of false warnings significantly. Alternately, you can put
+ \verb+% chktex-file 18+ in your files which use one of these packages so
+ that other files will still have these checks performed.
+\item Put \Cmd{-v} in the \Cmd{CmdLine} entry of the \rsrc\ file; this
+ makes the fancy printing the default.
+\item If you're working on a large project, it may pay off to make a
+ local resource file which is included in addition to the global
+ one. In this one, add the necessary info to reduce the amount of
+ false warnings --- these usually don't do anything but hide the
+ real warnings.
+\item Create a total ignore environment, which \chktex\ will ignore
+ completely. In here, you can place all that code which outsmarts
+ \chktex\ completely. For instance, add the following lines at the top
+ of your \LaTeX\ file:
+\begin{verbatim}
+% ChkTeX will ignore material within this environment
+\newenvironment{ignore}{}{}
+\end{verbatim}
+ In addition, you should add the item \Cmd{ignore} to the \Cmd{VerbEnvir}
+ entry in the \rsrc\ file.
+\end{itemize}
+\subsubsection{Bugs}
+
+No fatal ones, I think, but the program currently has some problems when a
+\LaTeX\ command/parameter stretch over a two lines --- some extra spaces
+may be inserted into the input. I regard the program as fairly well
+tested; using the SAS/C \Cmd{cover} utility I was able to make sure that
+approximately 95\% of the code has actually been run successfully in the
+final version. This does indeed leave some lines; most of these are
+procedure terminating brackets or ``can't happen'' lines, though.
+
+We've got some problems when isolating the arguments of a command.
+Although improved, it will certainly fail in certain cases; \chktex\
+can for instance not handle arguments stretching over two lines. This
+also means that \Cmd{WIPEARG} entries in the \rsrc\ file will only
+have the first half of their argument wiped if the argument stretches
+over two lines. We will, however, take care not to wipe parenthesis
+in such cases, in order to avoid false warnings.
+
+Long lines are broken up into chunks and handled separately. The exact
+length is platform dependent, though is guaranteed to be at least 256 bytes.
+The first portions of the line will have line numbers that are 1 less than
+they should be. Some errors can be missed and some can be added erroneously.
+A warning will be issued if lines are too long.
+
+Before submitting a bug report, please first see whether the problem can be
+solved by editing the \rsrc\ file appropriately.
+
+
+
+\subsection{ChkWEB}
+
+This shell script is provided for checking CWEB files. The template is
+as follows:
+\begin{verbatim}
+chkweb [options] file1 file2 ...
+\end{verbatim}
+As you may see from the script, it is only a trivial interface towards
+\texttt{deweb} and \chktex. It does not support any individual options
+on the command line --- all options found will be passed onto \chktex.
+If \Cmd{-{}-} or a filename is found, the remaining parameters will be
+ignored.
+The only real intelligence it features is that it will try to append
+\verb@.w@ to filenames it can't find.
+
+If no filenames are given, we will read from \texttt{stdin}.
+
+\subsection{DeWEB}
+
+This program strips away C code and CWEB commands from CWEB sources.
+It is called with the following synopsis:
+
+\begin{verbatim}
+deweb file1 file2 ...
+\end{verbatim}
+
+\texttt{deweb} filters away all C \&\ CWEB commands from a CWEB source
+code. This leaves only the \LaTeX\ code. This stripped code, in turn,
+may then be passed to a suitable syntax checker for \LaTeX, like
+\chktex\ and \texttt{lacheck}, or spell-checkers like \texttt{ispell}.
+
+When \texttt{deweb} strips away the C code from your CWEB source, it tries to
+preserve line breaks. This means that the error reports from {\it your
+ favorite tool\/} will be correct regarding to line numbers. In most
+cases, the column position will also be correct. This significantly
+simplifies finding the errors in the \LaTeX\ source (in contrast to the
+output from \texttt{cweave}, which output is truly difficult to figure
+anything out from).
+
+\texttt{deweb} accepts a list of filenames on the argument line, and will send
+its output to \texttt{stdout}. If no filenames are given, it will read from
+stdin, acting as a filter. No options are currently accepted.
+
+Macho users may try to pipe the output from \texttt{deweb} directly into
+\LaTeX, theoretically, this should work. This would ease the debugging of
+the \LaTeX\ code significantly, as when \LaTeX\ complains about wrong
+syntax, you'll be able to find the erroneous line much more easily. Don't
+expect that the output looks very much like the final one, though.
+
+\texttt{deweb} should now understand all correct \texttt{CWEB} opcodes. If it
+complains about not understanding a correct opcode, please inform the
+author.
+
+\subsubsection{Bugs}
+
+\texttt{deweb} will not even \emph{compile} under Perl versions before perl
+v5. Unfortunately, this means that we can't even tell the user why we
+failed; Perl will just complain about not being able to compile the
+regexps.
+
+\section{Explanation of error messages}
+Below is a description of all error-messages \chktex\ outputs.
+Error messages set in {\it italic type\/} are turned off by default.
+Where margin paragraphs are listed in the text, they refer to the
+keyword in the \rsrc\ file which controls the discussed warning.
+
+\newcommand\Keyword[1]{\marginpar{\texttt{\hfill\\ #1}}}
+
+\smallskip\pagebreak[2]
+\Keyword{Silent}
+\begin{errdesc}{Command terminated with space.}
+ You tried to terminate a command with a blank space. Usually, this
+ is an error as these are ignored by \LaTeX. In most cases, you would
+ like to have a real space there.
+
+ You can also specify regular expressions to match commands which can
+ safely be terminated with a space. They are specified in the
+ \rsrc\ file in \texttt{[]}, which in some other cases is used to
+ indicate case-insensitive matching. This is used for example to
+ support the \verb+\startXXX+ macros of Con\TeX t.
+
+ \begin{errexam}
+ \verb@\LaTeX@\underline{\tt\ }\verb@is a typesetter.@ \\*
+ \LaTeX is a typesetter. \\*
+ \smallskip
+ \verb@\LaTeX\ is a typesetter.@ \\*

+ \end{errexam}
+\end{errdesc}
+
+\Keyword{Linker}
+\begin{errdesc}{Non-breaking space (`\~{}') should have been used.}
+ When reading a document, it is not very pretty when references are
+ split across lines. If you use the \verb@~@ character, \LaTeX\ will
+ assign a very high penalty for splitting a line at that point.
+ \chktex\ issues this warning if you have forgot to do this.

+\Keyword{HyphDash\\NumDash\\WordDash\\DashExcpt}
+\begin{errdesc}{Wrong length of dash may have been used.}
+ This warning suggests that a wrong number of dashes may have been

+ character in front and after the dashes.
+
+ If they are of the same type, \chktex\ will determine which keyword

+ Space & \texttt{WordDash} \\*
+ Number & \texttt{NumDash} \\*
+ Alphabetic character & \texttt{HyphDash} \\*
+ \end{tabular}
+
+ This is more or less correct, according to my references. One
+ complication is that most often a hyphen (single dash) is desired
+ between letters, but occasionally an n-dash (double dash) is
+ required. This is the case for theorems named after two people
+ e.g.\ Jordan--H\"older. A hyphen would indicate that it was one
+ person with a hyphenated name e.g.\ Gregorio Ricci-Curbastro.
+ If this is rare enough, it can be dealt with via line based suppressions.
+ However, exceptions can also be handled by adding them to the
+ \texttt{DashExcpt} list. The ``words'' in this list are
+ considered to be correct regardless of any other settings.
+ Adding \verb+Jordan--H\"older+ to this list will cause no warning
+ to be issued. There is still the problem that no warning will be
+ raised for Jordan-H\"older (unless added explicitly via regular
+ expression), so care must still be taken.
+
+ Some manuals---particularly American manuals---also suggest
+ \emph{not} adding space around an m-dash (triple dash).

+ Depending on how \chktex\ was configured, you can use either PCRE regular
+ expressions, POSIX extended regular expressions, or none at all.
+ A warning will be issued if \chktex\ was built without regular expression
+ support, but you try to use one.
+
+ By default the matching portion of the line is printed to help distinguish
+ between user specified regular expressions. However, if the regular
+ expression begins with a PCRE comment (which has a syntax of
+ \verb+(?#+~\dots~\verb+)+), then that comment will be printed instead.
+ This can be used to remind yourself why you were searching for the problem
+ or how to fix it. This applies even if POSIX regular expressions are used
+ since \chktex\ itself parses a single initial PCRE-style comment.
+
+ \emph{Note:} If a regular expression (not a comment) starts with
+ \texttt{PCRE:} or \texttt{POSIX:} it will be used only if support for that
+ regular expression engine has been compiled in. It is primarily meant to
+ make testing easier but, can be used to allow better regular expressions
+ if PCRE is available. If you want a regular expression that starts with
+ \texttt{PCRE:} or \texttt{POSIX:} then you can enclose one of the
+ characters in brackets like \texttt{[P]CRE:}.
+
+ An example, included in the \rsrc\ file, is given below. Remember that you
+ have to escape (with~\verb+!+) spaces and \verb+#+ as well as a few other
+ characters. One should always use \verb+\nmid+ instead of \verb+\not\mid+
+ because the results are much better.

+ You can use \verb+% chktex 44+ to suppress user regular expression

+ \verb+% chktex 4+ will suppress the system warning number 4, but
+ \verb+% chktex -4+ will suppress the user regular expression warning
+ number 4. Since one might wish to add, remove, or rearrange user warnings
+ in the \rsrc\ file, you must explicitly name particular warnings rather
+ than relying on position in that file.
+
+ In order to name one, include an initial PCRE-style comment with the first
+ characters being a number (positive or negative---the absolute value will
+ be used). The numbers are limited by the number of bits in a \texttt{long},
+ usually giving 1--63 as possible names. You can give more than one regular
+ expression the same name, and suppressing that name will suppress all
+ regular expressions with that name.
+
+ Using the example from before, all of the following will be suppressed with
+ \verb+% chktex -4+. Note that the name \emph{will} be printed as written
+ so that you know which number to suppress.
+ \begin{errexam}
+ \verb+(?!#4:Always! use! \nmid)\\not! *(\||\\mid)+\\*
+ \verb+(?!#-4Always! use! \nmid)\\not! *(\||\\mid)+\\*
+ \verb+(?!#-4! Always! use! \nmid)\\not! *(\||\\mid)+\\*
+ \end{errexam}
+\end{errdesc}
+
+\begin{errdesc}{Use \textbackslash[ ... \textbackslash] instead of \$\$ ... \$\$.}
+
+ In \LaTeX\ documents, using \verb+\[...\]+ is strongly preferred over \verb+$$...$$+.
+ This is because using \verb+$$+ will change the vertical spacing in the
+ equations making them inconsistent.
+
+\end{errdesc}
+
+\begin{errdesc*}{Use \textbackslash( ... \textbackslash) instead of \$ ... \$.}
+
+ In \LaTeX\ documents using \verb+\(...\)+ is slightly preferred over \verb+$...$+.
+ Some error messages might be clearer with \verb+\(...\)+.
+
+\end{errdesc*}
+
+\section{Future plans}
+
+In a somewhat prioritized sequence, this is what I'd like to put into the
+program --- if I have the time.
+
+\begin{itemize}
+\item De-linearize the checker. Currently, it works on a line-by-line
+ basis, in most respects, at least. I hope to be able to remove this
+ barrier; as this will reduce the amount of false warnings
+ somewhat.
+
+\item Probably some more warnings/errors; just have to think them out
+ first. Suggestions are appreciated --- I've ``stolen'' most that
+ similar programs provides, and am running out of ideas, really.
+
+ It would also be nice to investigate the field of ``globally''
+ oriented warnings; i.e.\ warnings regarding the document as a
+ whole. Currently, \chktex\ operates mainly on a local/``greedy''
+ basis.
+
+ If you have suggestions/ideas on this topic, they're certainly
+ welcome, including references to literature.
+
+\item Fix a few more bugs.
+\end{itemize}
+
+\section{Notes}
+
+\subsection{Wish to help?}
+
+As most other living creatures, I have only a limited amount of time. If
+you like \chktex\ and would like to help improving it, here's a few things
+I would like to receive. The following ideas are given:
+
+\begin{itemize}
+\item Does anyone have a $\mbox{\LaTeX}\rightarrow \mbox{\texttt{troff}}$
+ conversion program? It would be really nice if I could extract the
+ relevant sections from this manual, and present them as a man page.
+ I will not, however, convert this manual to \TeX{}info in order to
+ be able to do this; IMHO \TeX{}info documents have far too limited
+ typographic possibilities.
+
+ This doesn't mean that I'm not willing to restructure the document
+ at all. This manual already uses some kind of preprocessing in order
+ to achieve HTML output via \LaTeX2\texttt{html}, I'm willing to do the
+ same in order to produce \texttt{troff} output.
+
+\item Help me port the program! This is a prioritized one. It's no fun
+ writing ANSI C when people haven't got a C compiler.
+
+ Of course, I'll provide whatever help necessary to modify the sources
+ to fit to the new platform. Take contact if you're interested. I will
+ include your compiled binary in the distribution, and give you
+ credit where appropiate.
+
+ Just one request: If you have to modify the sources in order to make
+ \chktex\ compile \& work on the new platform, \emph{please} enclose your
+ changes in something like \Cmd{\#ifdef \_\_PLATFORM\_\_\dots code\dots\#endif}!
+ It makes life so much easier later, when we try to merge the two
+ source trees.
+
+\item Reports on problems configuring and compiling \chktex\ on supported
+ (and unsupported) systems are welcomed.
+
+\item Filters for other file formats. I do believe that there are
+ several formats using \LaTeX\ for its formatting purposes, combining
+ that with something else. If you can write a program or script which
+ filters everything away but the \LaTeX\ code, it will surely be
+ appreciated (and included). Look at the \verb@deweb@ script to see
+ what I mean.
+
+\item Interfaces for other editors are also welcomed.
+
+\item If you update the \rsrc\ file in anyway that is not strictly
+ local, I would appreciate to receive your updated version.
+
+\item Suggestions for new warnings are always welcomed. Both formal
+ (i.e.\ regexps or similar) and non-formal (plain English) descriptions
+ are welcomed.
+\end{itemize}
+
+Of course, people doing any of this will be mentioned in this document, and
+thus receive eternal glory and appreciation.
+
+\subsection{Caps and stuff}
+
+Where trademarks have been used, the author is aware of that they
+belong to someone, and has tried to stick to the original caps.
+
+\section{About the author}
+
+A quick summary of who I am and what I do:
+
+I'm 21 years old, and live in Oslo, the capital of Norway. I'm
+currently studying maths and computer science at the
+University~of~Oslo; planning to get a degree within mathematical
+modeling, with a dash of physics and emphazing the computer part of
+the study. More precisely, in autumn'96 my studies consist of
+mathematical analysis, statistics \& probability calculations plus
+studying the relationship between society and computers.
+
+At home I now possess 4 computers, of which 1 is regular use: A
+vanilla Amiga 1200, expanded only by a HD\@. The others are a
+\texttt{80286} PC and an Amiga 500, both semi-out-of-order. The last
+one is a Commodore VIC-20, which for some peculiar reason never seems
+to be used. Plans are to get a Linux-capable PC, though.
+
+Most of the time in front of these computers (including SGI Indy's and
+SPARC stations at our university) is spent on C and shell programming,
+plus some text-processing.
+
+ % I am also involved in writing the document
+ % for {\sc Isaac} --- Interactive Simulation as an Alternative to
+ % Advanced Calculations. This is planned to help newcomers to physics,
+ % by providing a computer program which enables one to simulate most
+ % experiments relating to classical mechanics.
+ %
+
+C and shell programming are not my only knowledge areas regarding
+computers, however. I write the following languages more or less:
+Perl, Motorola \texttt{68000} assembly code, ARexx, Simula, C++, \LaTeX,
+HTML, AmigaGuide, Amos Basic and Installer LISP\@. Once I also
+mastered Commodore Basic V2, the ``language'' included with my VIC-20.
+
+However, I also try to not to end up as a computer nerd. Thus, in
+addition to the compulsory (?) interest for computers, I am a scout.
+Still running into the woods, climbing the trees, falling down and
+climbing up once more, in other words. To be more specific, I am a
+now a troop leader for `Ulven' scout-group; Norwegian Scouts
+Association. I am also a active rover in `V{\aa}lerenga' scout-group.
+
+Certainly a lot more to tell (I play the piano and like cross-country
+skiing, for instance); but I'll stop here before you fall
+asleep\dots

+
+ \Name{Russ Bubley}{russ@scs.leeds.ac.uk}
+ He has been the main external beta-tester for this program, sending
+ me loads and loads of understandable and reproducible bug reports.
+ If you somehow think that \chktex\ is well-behaved and free from
+ bugs, send warm thoughts to Russ. He has also provided ideas for
+ enhanced checks and so forth.
+
+ In addition, he sent me a huge list of 238 common English
+ abbreviations, for inclusion in the \rsrc\ file! Together with the
+ enhanced abbreviation recognizer, I do now believe most
+ abbreviations should be caught\dots
+
+ Finally, he has also given me valuable hints for improving the
+ program's outputting routine, and given me lots of suggestions for
+ filtering unnecessary/false warnings away.
+
+ \Name{Gerd B\"ohm}{Gerd.Boehm@physik.uni-regensburg.de}
+ Improved and bug-fixed the MS-DOS port of \chktex\ v1.4, sending me
+ ready-to-yank code patches. The original port didn't respect all
+ the peculiarities of the MS-DOS file-system, unfortunately.
+
+ \Name{Antonio DiCesare}{dicesare@vodafone.it}
+ He provided many feature requests and bug reports for the 1.7.1
+ version making it a much better release than it would have otherwise
+ been. He also helped expand several keywords in the \rsrc\ file.
+
+ \Name{Mojca Miklavec}{mojca.miklavec.lists@gmail.com}
+ Found and helped debug a problem (fixed in 1.7.2) occurring only on
+ some platforms, 32 bit Macs for one.
+
+ \Name{Baruch Even}{chktex@ev-en.org}
+ Maintainer of \chktex\ for about a decade.
+
+ \Name{Lars Frellesen}{frelle@math-tech.dk} Sent a few bug reports
+ regarding the filtering of messages. He has also helped me to
+ expand the \Cmd{SILENT} keyword in the \rsrc\ file.
+
+ \Name{Wolfgang Fritsch}{fritsch@hmi.de}
+ Author of the OS/2 port, which he did using the emx compiler.
+ Please direct questions regarding strictly to that port to him (I
+ would like to receive a carbon copy, though).
+
+ \Name{Stefan Gerberding}{stefan@inferenzsysteme.informatik.th-darmstadt.de}
+ First one to report the Enforcer hit in v1.2 when using \chktex\ as
+ a pipe. Also came with suggestions to make \chktex\ more easily
+ compile on early gcc compilers.
+
+ He has also kept on beta-testing later versions of \chktex, giving
+ me bug-reports and enhancements requests.
+
+ \Name{Kasper B. Graversen}{kbg2001@internet.dk} Lots of creative
+ suggestions and improvements. Several of the warnings implemented
+ were based on his ideas. In addition, he has given advice for
+ improving the existing warnings.
+
+ Has also provided some OS-oriented code.
+
+ \Name{Frank Luithle}{f\_luithle@outside.sb.sub.de}
+ Wrote a translation for v1.0. Unfortunately, he remained unreachable
+ after that\dots:-/
+
+ \Name{Nat}{nat@nataa.frmug.fr.net}
+ Reported the same bug as Gerberding. In addition, he taught me a
+ few tricks regarding the use of gcc + made me understand that the
+ ANSI standard isn't unambigious; at least the \verb@getenv()@ call
+ seem to be open for interpretations. Many possible
+ incompatibilities have been removed due to these lessons.
+
+ \Name{Michael Sanders}{sanders@umich.edu}
+ Has found some of the bugs in this beast; both obscure and
+ long-lived. Has also provided motivation to clarify this document.
+
+ \Name{Bj\o rn Ove Thue}{bjort@ifi.uio.no}
+ Author of the MSDOS port; please direct questions regarding
+ strictly to that port to him (I would like to receive a carbon
+ copy, though).
+
+ \Name{Martin Ward}{Martin.Ward@durham.ac.uk}
+ Sent a few bug-reports; also gave me information upon where to find
+ regexp code. He also provided a Perl script for checking ordinary
+ text, which ideas I was able to implement in \chktex. In addition,
+ he sent me the source code for \verb@lacheck@; which also inspired some
+ of the warnings.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a

+
+------------------------------------------------------------------------
+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) 19yy <name of author>

+ USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) 19yy name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+

+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+\section{Introduction}
+
+This program has been written in frustration because some constructs in
+\LaTeX\ are sometimes non-intuitive, and easy to forget. It is
+\emph{not} a replacement for the built-in checker in \LaTeX\@; however it
+catches some typographic errors \LaTeX\ oversees. In other words, it
+is Lint for \LaTeX. Filters are also provided for checking the
+\LaTeX\ parts of CWEB documents.
+
+It is written in ANSI C and compiles silently under GCC using
+\Cmd{-Wall -ansi -pedantic} and almost all warning flags. This means
+that you can compile \& use the program on your favorite machine.
+Full source included.
+
+The program also supports output formats suitable for further
+processing by editors or other programs, making errors easy to cycle through.
+For example, recent versions of AUC\TeX\ (the Emacs mode) interface
+beautifully with \chktex.
+
+The program itself does not have any machine requirements; However compiling
+for other platforms has not been done for a long time now so the code has been
+removed. If interest rises it can be resurrected.
+
+
+\section{Features}
+\chktex\ begins to get quite a few bells \& whistles now. However, you
+should be aware of that in most cases, all this is transparent to the user.
+As you will see, \chktex\ offers the ability to adapt to many environments
+and configurations.
+
+\begin{itemize}
+\item Supports over 40 warnings. Warnings include:
+%latex
+ \begin{multicols}{2}
+ \begin{flushleft}
+%endlatex
+ \begin{itemize}
+ \item Commands terminated with space. Ignores \Cmd{\BS{}tt}, etc.
+ \item Space in front of references instead of \Cmd{\~{}}.
+ \item Forgetting to group parenthesis characters when
+ sub-\slash{}super\-scripting.
+ \item Italic correction (\Cmd{\BS/}) mistakes (double,
+ missing, unnecessary).
+ \item Parenthesis and environment matching.
+ \item Ellipsis detection; also checks whether to use
+ \Cmd{\BS{}dots}, \Cmd{\BS{}cdots} or \Cmd{\BS{}ldots}.
+ \item Enforcement of normal space after abbreviation. Detects
+ most abbreviations automagically.
+ \item Enforcement of end-of-sentence space when the last
+ sentence ended with capital letter.
+ \item Math-mode on/off detection.
+ \item Quote checking, both wrong types (\Cmd{"}) and wrong
+ direction.
+ \item Recommends splitting three quotes in a row.
+ \item Searching for user patterns.
+ \item Displays comments.
+ \item Space in front of \Cmd{\BS{}label} and similar commands.
+ \item Use of \Cmd{x} instead of \Cmd{\$\BS{}times\$} between numbers.
+ \item Multiple spaces in input which will be rendered as one
+ space (or multiple spaces, where that is undesirable).
+ \item Warns about text which may be ignored.
+ \item Mathematical operators typeset as variables.
+ \item No space in front of/after parenthesis.
+ \item Demands a consistent quote style.
+ \item Punctuation inside inner math mode/outside display math
+ mode.
+ \item Use of \TeX\ primitives where \LaTeX\ equivalents are
+ available.
+ \item Space in front of footnotes.
+ \item Bogus characters following commands.
+ \item Ability to suppress warnings on a single line.
+ \end{itemize}
+%latex
+ \end{flushleft}
+ \end{multicols}
+%endlatex
+\item Fully customizable. Intelligent resource format makes it
+ possible to make \chktex\ respect your \LaTeX\ setup. Even
+ command-line options may be specified globally in the \rsrc\ file.
+\item Supports \Cmd{\BS{}input} command; both \TeX\ and \LaTeX\ version.
+ Actually includes the files. \Cmd{TEXINPUTS}-equivalent search path.
+\item Intelligent warning/error handling. The user may promote/mute
+ warnings to suit his preferences. You may also mute warnings in the
+ header of a file; thus killing much unwanted garbage.
+\item Scripts included for checking CWEB files written in \LaTeX.
+ (Requires perl v5).
+\item Supports both \LaTeX\ 2.09 and \LaTeXe{}.
+\item Flexible output handling. Has some predefined formats and lets
+ the user specify his own format. Uses a \Cmd{printf()} similar
+ syntax. \Cmd{lacheck} compatible mode included for interfacing with
+ systems which only support lacheck.
+\item Written in ANSI C\@. \Cmd{configure} script included for easy
+ setup and installation on UNIX systems.
+\end{itemize}
+
+Still, it is important to realize that the output from \chktex\ is
+only intended as a \emph{guide} to fixing faults. However, it is by
+no means always correct. This means that correct \LaTeX\ code may
+produce errors in \chktex, and vice versa: Incorrect \LaTeX\ code may pass
+silently through.
+
+

+\section{Availability}
+
+This program is on CTAN\@; thus it can be found at any mirrors of those.
+It is also part of TeX Live 2011.
+
+\section{Installation}
+
+A few words on installation on various platforms:
+
+\begin{description}
+\item[UNIX:] Type \Cmd{configure}, \Cmd{make} and finally
+ \Cmd{make~install}. To make sure everything proceeded correctly,
+ type \Cmd{make~check}. If you don't have superuser privileges and thus
+ access to the default system areas, you should type
+ \Cmd{configure~-{}-help} to help you set up correct paths.
+
+ If you haven't installed any software like this before, that is
+ distributed in source form, here are some guidelines to help you
+ install it locally at your account. Please note that a mail to the
+ system administrator may be less work for you.
+
+ We assume that you have put the archive (\Cmd{chktex.tar.gz}) in a
+ subdir of yours, with path \Cmd{\~{}/tmp}. We further assume that
+ your shell is \Cmd{csh} or \Cmd{tcsh}. Do the following:
+
+ \begin{enumerate}
+ \item First of all, unpack the archive contents.
+
+\begin{verbatim}
+> cd ~/tmp
+> gunzip chktex.tar.gz
+> tar xf chktex.tar
+\end{verbatim}
+
+ \item Now, we can configure the program. There are some
+ configuration options you should know about:
+ \begin{description}
+ \item[\Cmd{-{}-enable-pcre}:] Allows using PCRE (perl compatible
+ regular expressions) for use defined warnings. The default is
+ to use PCRE if it is installed on your system as determined by
+ \Cmd{pcre-config}. You can use \Cmd{-{}-disable-pcre} if you
+ plan to distribute this for systems in which you cannot ensure
+ PCRE will be installed.
+
+ User defined regular expressions are defined using
+ \texttt{UserWarnRegex} in the \rsrc\ file. See warning~44 for
+ more information.
+
+ \item[\Cmd{-{}-enable-lacheck-replace}] This enables a quick
+ hack for using \chktex\ instead of lacheck. This is done by
+ installing a stub script which ``overrides'' the original
+ lacheck executable. In this way, tools which support lacheck
+ can be easily made to support chktex instead.
+
+ \item[\Cmd{-{}-enable-debug-info}] \chktex\ has an ability to spit
+ out various diagnostic messages using the \Cmd{-d} flag. This
+ behaviour is on by default. By adding the flag
+ \Cmd{-{}-disable-debug-info} to the commandline, this will not be
+ compiled in.
+
+ This may be useful if you're running short of disk space (the
+ time savings are neglible).
+ \end{description}
+
+ If you are installing the program on your local account, use the
+ following command:
+
+\begin{verbatim}
+> configure --prefix ~/
+\end{verbatim}
+
+ Add eventual extra flags as specified above. This command will
+ generate a significant amount of output, this can usually be ignored.
+
+ \item Finally, we can just build the program and install it.
+
+\begin{verbatim}
+> make
+> make install
+\end{verbatim}
+
+ \item Finished! The program is now installed and ready to use. You
+ may now tell other people to put your bindir in their path in
+ order to benefit from your work. All that remains is to make the
+ shell aware of your installation.
+
+\begin{verbatim}
+> rehash
+\end{verbatim}
+
+ To make the remaining parts of your system aware of this, you'll
+ have to log out and re-log in, I'm afraid. However, you should delay this
+ until you've completed this installation procedure.
+
+ \item If you wish to make sure that everything is OK (you ought to),
+ you may now ask \chktex\ to do a self-test:
+
+\begin{verbatim}
+> make check
+\end{verbatim}
+
+ \end{enumerate}
+
+\item[Other platforms:] First of all, you have to copy the
+ \Cmd{config.h.in} file to a file named \Cmd{config.h}. Then, edit
+ it to reflect your system. Do the same with \Cmd{OpSys.h} (this
+ file has been reduced significantly). If you wish, you may define
+ \Cmd{DATADIR} to the path you want the global resource file to be
+ put.
+
+ Now, I would suggest that you take a peak at the \Cmd{OpSys.c}
+ file, and edit it appropiately, for more
+ comfort. This should not be necessary, though, at least not the
+ first time.
+
+ Finally, you may now compile and link all \verb@.c@ files. Do not
+ forget to define \Cmd{HAVE\_CONFIG\_H} to 1 (on the command-line,
+ for instance). If the \Cmd{config.h} you wish to use has another
+ name, define \Cmd{CONFIG\_H\_NAME} to that (in that case, don't
+ define \Cmd{HAVE\_CONFIG\_H}).
+
+ Put the directory path of the \rsrc\ file in a environment variable
+ named \Cmd{CHKTEXRC}. The files \Cmd{deweb.in} and \Cmd{chkweb}
+ should be moved to a directory in your path. These files may need
+ further setup, as they haven't got the location of perl
+ initialized.
+
+ If your compiler/the compiled program complains (or crashes!), you
+ may try the hints listed below. Please note that it only makes
+ sense to try these hints if your compiler fails to produce a working
+ program.
+
+ \begin{enumerate}
+ \item Increase the preprocessor buffers and line buffers. The
+ \chktex{} sources define macros sized 3--4k (expanding to about
+ the same), and passes arguments sized about 1k.
+ \item Use the magic switch which lets us use large
+ \Cmd{switch(\dots)\{\dots\}} statements; some of these statements
+ have about 120 \Cmd{case} entries.
+ \item The sources require that at least the first 12 of each
+ identifier is significant.
+ \end{enumerate}
+\end{description}
+\paragraph{Note:} You \emph{must} install the new \rsrc\ file; \chktex\ will
+fail to function otherwise!
+
+ After doing this, you may enhance \chktex' behaviour by
+reading/editing the \rsrc\ file.

+\section{Usage}
+
+\subsection{\chktex}
+
+\subsubsection{Synopsis}
+
+A UNIX-compliant template format follows:
+
+\newcommand{\Group}[1]{\mbox{[#1]}}
+\begin{tabularx}{.95\linewidth}{lY}
+ \texttt{chktex} & \ttfamily \Group{-hiqrW} \Group{-v[0-\dots]} \Group{-l
+ <rcfile>} \Group{-[wemn] <[1-42]|all>} \Group{-d[0-\ldots]} \Group{-p
+ <pseudoname>} \Group{-o <outputfile>} \Group{-[btxgI][0|1]}
+ file1 file2 \dots
+\end{tabularx}
+
+
+\subsubsection{Options}
+
+These are the options \chktex\ currently accepts.
+Please note that single-lettered options requiring a numerical or no
+argument may be concatenated. E.g.\ saying \Cmd{-v0qb0w2} is the
+same as saying \Cmd{-v0~-q~-b0~-w2}, except for being less to
+type.
+
+Enough general talk; here's a rather detailed description of all
+options:
+\begin{description}
+\item[Misc.\ options:] General options which aren't related to some
+ specific subpart of \chktex.
+ \begin{description}
+ \item[\texttt{-h [-{}-help]}] Gives you a command summary.
+ \item[\texttt{-i [-{}-license]}] Shows distribution information.
+ \item[\texttt{-l [-{}-localrc]}] Reads a resource-file formatted
+ as the global resource-file \rsrc, in addition to the global
+ resource-file. This option needs the name of the resource-file
+ as a parameter. See also \texttt{-g}.
+ \item[\texttt{-r [-{}-reset]}] This will reset all settings to their
+ defaults. This may be useful if you use the \texttt{CMDLINE}
+ directive in your \rsrc\ file, and wish to do something
+ unusual.
+ \item[\texttt{-d [-{}-debug]}] Needs a numeric argument; a bitmask
+ telling what to output. The values below may be added in order
+ to output multiple debugging info.
+
+ \begin{tabularx}\linewidth{cX}
+ \bf Value & \bf Dumps\ldots\\
+ 1 & All warnings available and their current status. \\
+ 2 & Statistics for all lists in the resource file. \\
+ 4 & The contents of all lists in the resource file. \\
+ 8 & Misc.\ other status information. \\
+ 16 & Run-time info (note that this isn't widely used). \\
+ \end{tabularx}
+ The info is produced after all switches and resource files have
+ been processed.
+
+ It is possible to install versions of \chktex\ that ignore this
+ flag; this means that it is not certain that this flag works.
+ \item[\texttt{-W [-{}-version]}] Displays version information, and exits.
+ \end{description}
+\item[Muting warning messages:] Controls whether and in what form
+ error messages will appear. Usually they accept a specific warning
+ number (e.g.\ \Cmd{-w2}), but you may also say \Cmd{all} (e.g.\
+ \Cmd{-wall}) which does the operation on \emph{all} warnings.
+ \begin{description}
+ \item[\texttt{-w [-{}-warnon]}] Makes the message number passed as
+ parameter a warning and turns it on.
+ \item[\texttt{-e [-{}-erroron]}] Makes the message number passed as
+ parameter an error and turns it on.
+ \item[\texttt{-m [-{}-msgon]}] Makes the message number passed as
+ parameter a message and turns it on. Messages are not counted.
+ \item[\texttt{-n [-{}-nowarn]}] Turns the warning/error number passed
+ as a parameter off.
+ \item[\texttt{-L [-{}-nolinesupp]}] Turns off suppression of messages
+ on a per line basis. This is meant to be used to ensure that no new
+ errors have crept into a document while editing.
+ \end{description}
+\item[Output control flags:] Determines the appearance and
+ destination of the error reports.
+ \begin{description}
+ \item[\texttt{-q [-{}-quiet]}] Shuts up about copyright information.
+ \item[\texttt{-o [-{}-output]}] Normally, all errors are piped to \texttt{stdout}.
+ Using this option with a parameter, errors will be sent to the
+ named file instead. Only information relative to the \LaTeX\ file
+ will be sent to that file. Memory problems and similar will as as
+ always be sent to \texttt{stderr}. If a file with the name given
+ already exists, it will be renamed to \Cmd{foobar.bak}
+ (\Cmd{foobar.\$cl} under MS-DOS), \Cmd{foobar} being the name of
+ the file. See also \Cmd{-b}.
+
+ \item[\texttt{-v [-{}-verbosity]}] Specifies how much and how you
+ wish the error reports to be displayed. This is specified in the
+ \rsrc\ file; we'll list the default values below. If you wish,
+ you may thus edit the \rsrc\ file to add or modify new formats.
+
+ The default is mode 1 (that is, the \emph{second} entry in the
+ \rsrc\ file), using \texttt{-v} without any parameter will give you
+ mode 2.
+
+ \begin{description}
+ \item[0] Will show the information in a way that should be
+ suitable for further parsing by \texttt{awk}, \texttt{sed} or
+ similar. The format is as follows:
+\begin{verbatim}
+File:Line:Column:Warning number:Warning message
+\end{verbatim}
+ The colons may be replaced with another string; use the
+ \verb@-s@ switch for this.
+
+ As the program does not output all errors in quite order, this
+ output format is also suitable for piping through \Cmd{sort}.
+ \item[1] Shows the information in a way which is more
+ comprehensible for humans, but which still doesn't need
+ anything but a glass tty.
+ \item[2] Shows the information in a fancy way, using escape
+ codes and stuff. It is the indeed most readable of all
+ modes; however, it needs proper set up of the \Cmd{ChkTeX.h}
+ at compilation time. UNIX boxes, however, will find the
+ information automatically.
+ \item[3] Shows the information suitable for parsing by Emacs;
+ this is the same format as \texttt{lacheck} uses. More formally,
+ it is the following:
+\begin{verbatim}
+"File", line Line: Warning message
+\end{verbatim}
+
+ To utilize this, type \verb@M-x compile RET@. Delete whatever
+ is written in the minibuffer, and type
+ \verb@chktex -v3 texfile.tex@, and you should be able to
+ browse through the
+ error messages. Use \verb@C-x `@ to parse the messages.
+ \item[4] More or less the same as \verb@-v3@, but also includes
+ information on where the error actually was found. Takes somewhat
+ longer time to parse, but much more informative in use.
+ \end{description}
+
+ \item[\texttt{-f [-{}-format]}] Specifies the format of the output.
+ This is done using a format similar to \Cmd{printf()}, where we
+ support the specifiers listed below.
+
+ \smallskip
+ \newcommand{\Pf}[1]{\texttt{\%#1} &}
+ \begin{tabularx}{\linewidth}{cX}
+ \bf Code & \bf Description \\
+ \Pf{b} String to print \textbf{b}etween fields (from \texttt{-s}
+ option).\\
+ \Pf{c} \textbf{C}olumn position of error. \\
+ \Pf{d} Length of error (\textbf{d}igit). \\
+ \Pf{f} Current \textbf{f}ilename.\\
+ \Pf{i} Turn on \textbf{i}nverse printing mode.\\
+ \Pf{I} Turn off \textbf{i}nverse printing mode.\\
+ \Pf{k} \textbf{k}ind of error (warning, error, message).\\
+ \Pf{l} \textbf{l}ine number of error.\\
+ \Pf{m} Warning \textbf{m}essage.\\
+ \Pf{n} Warning \textbf{n}umber.\\
+ \Pf{u} An \textbf{u}nderlining line (like the one which
+ appears when using \Cmd{-v1}).\\
+ \Pf{r} Part of line in front of error ($\mbox{`S'} -
+ 1$).\\
+ \Pf{s} Part of line which contains error (\textbf{s}tring).\\
+ \Pf{t} Part of line after error ($\mbox{`S'} + 1$).
+ \end{tabularx}
+ \smallskip
+
+ Other characters will be passed literally; thus you can say
+ \Cmd{\%\%} to achieve a single percent sign in the output.
+ Please note that we may introduce other specifiers in the future,
+ so don't abuse this feature for other characters.
+
+ Also, note that we do \emph{not} support field lengths (yet).
+ This may come in the future, if I get the time\dots
+
+ The \texttt{-v} command is implemented by indexing into the \rsrc\
+ file; read that for seeing how each format is implemented. If
+ you find yourself using a particular format often by using the
+ -f switch, consider putting it in the \rsrc\ file instead.
+ \item[\texttt{-V [-{}-pipeverb]}] Which entry we'll use in the \rsrc\
+ file whenever \texttt{stdout} isn't a terminal.
+
+ The default is to use the same mode as specified with the
+ \texttt{-v} switch; using \texttt{-V} without any parameter will give you
+ mode 1.
+
+ This switch was implemented because GNU less has problems with
+ the escape codes \chktex\ uses for displaying inverse text.
+ Under UNIX, there's another way around, though, which is slightly
+ more elegant. Add the following line to your \Cmd{.envir} file:
+\begin{verbatim}
+setenv LESS -r
+\end{verbatim}
+
+ \item[\texttt{-p [-{}-pseudoname]}] With this switch, you can provide
+ the filename which will be used when we report the errors. This
+ may be useful in scripts, especially when doing pipes. It is in
+ other words similar to C's \verb@#line@ directive.
+
+ We will only assume this name for the uppermost file; files that
+ this one in turn \verb@\@\verb@input@ are presented under their original
+ names. This seems most logical to me.
+
+ \item[\texttt{-s [-{}-splitchar]}] String to use instead of the
+ colons when doing \texttt{-v0}; e.g.\ this string will be output
+ between the fields.
+
+ \end{description}
+\item[Boolean switches:] Common for all of these are that they
+ take an optional parameter. If it is \texttt{0}, the feature will
+ be disabled, if it is \texttt{1}, it will be enabled. All these
+ features are on by default; and are toggled if you don't give
+ any parameter.
+
+ \begin{description}
+ \item[\texttt{-b [-{}-backup]}] If you use the \texttt{-o} switch, and the
+ named outputfile exists, it will be renamed to \texttt{filename.bak}.
+ \item[\texttt{-I [-{}-inputfiles]}] Execute \verb@\@\verb@input@
+ statements; e.g.\ include the file in the input. Our input parsing
+ does of course nest; we use an input-stack to keep track of this.
+ \item[\texttt{-H [-{}-headererr]}] Show errors found in front of the
+ \verb@\begin{document}@ line. Some people keep \emph{lots} of
+ pure \TeX\ code there, which errors can't be detected reliably
+ (in other words, we will in most cases just produce a lot of
+ garbage).
+ \item[\texttt{-g [-{}-globalrc]}] Read in the global resource file. This
+ switch may be useful together with the \texttt{-l} option.
+ \item[\texttt{-t [-{}-tictoc]}] Display a twirling baton, to show that
+ we're working. \texttt{-v0} does an \texttt{-t0}, too, as it assumes
+ that the user then uses the program non-interactively. This is
+ now a no-op.
+ \item[\texttt{-x [-{}-wipeverb]}] Ignore the ``\verb@\verb@'' command
+ found within the \LaTeX\ file and its argument is completely by
+ the checking routines. This is done by simply overwriting them.
+ If you somehow don't like that (for instance, you would like to
+ count brackets inside those commands, too), use this switch.
+ \end{description}
+\end{description}
+
+
+If you don't specify any input \LaTeX-files on the commandline, we'll
+read from \texttt{stdin}. To abort \texttt{stdin} input, press the
+following keycombinations:
+
+\smallskip
+\begin{tabular}{ll}
+ \bf Machine & \bf Key-combination \\
+ UNIX & $\fbox{\texttt{Ctrl}} + \fbox{\texttt{D}}$ \\
+ MS-DOS & $\fbox{\texttt{Ctrl}} + \fbox{Z}$, followed by return.
+\end{tabular}
+\smallskip
+
+By default, we use GNU's \Cmd{getopt()} routine.
+
+\begin{itemize}
+\item Options may be given in any order; the names of the \LaTeX-files
+ do not have to be the last arguments. This behaviour may be turned
+ off by creating an environment variable named \Cmd{POSIXLY\_CORRECT}.
+\item The special argument \Cmd{-{}-} forces an end of
+ option-scanning.
+\item Long-named options begin with \Cmd{-{}-} instead of \Cmd{-}.
+ Their names may be abbreviated as long as the abbreviation is unique
+ or is an exact match for some defined option. If they have an
+ argument, it follows the option name in the argument, separated from
+ the option name by a \Cmd{=}, or else the in next argument.
+\end{itemize}
+
+\subsubsection{The \rsrc\ file}
+
+You should also take a look at the \rsrc\ file. As it is
+self-documenting, you should be able to get the meaning of each
+keyword by simply reading the file. In fact, since not all options
+are described in this documentation it is necessary that you read
+the \rsrc\ file in order to understand them all. The method for
+\emph{finding it} has grown rather complex. An outline is given below.
+
+If \chktex\ finds multiple files when searching, each and every one
+will be read in the order specified below. The \Cmd{Keyword = \{ item
+ item \dots \}} may thus be necessary to reset previously defined
+lists.
+
+In this list, \Cmd{\$foo} is assumed to be the environment variable
+\Cmd{foo}:
+
+\begin{enumerate}
+\item First, we'll take a look at the directory which was specified as
+ \Cmd{DATADIR} during compilation. On UNIX boxes, this usually
+ evaluates to something similar to
+ \Cmd{/usr/local/share/chktexrc}, under MS-DOS it is set
+ to \Cmd{\BS{}emtex\BS{}data\BS{}chktexrc}.
+
+\item Look in the following system directories:
+
+ \begin{tabular}{ll}
+ \bf Machine & \bf Directory \\
+ UNIX & \Cmd{\$HOME/.chktexrc} or \Cmd{\$LOGDIR/.chktexrc} \\
+ MSDOS & Program installation path
+ \end{tabular}
+
+\item Look for it in the directory pointed to by an environment
+ variable, as specified in the table below:
+
+ \begin{tabularx}\linewidth{lY}
+ \bf Machine & \bf Directory \\
+ UNIX & \Cmd{\$CHKTEXRC/.chktexrc} \\
+ MSDOS & \Cmd{\$CHKTEXRC\BS{}chktexrc}, \Cmd{\$CHKTEX\_HOME\BS
+ chktexrc} or \Cmd{\$EMTEXDIR\BS{}data\BS{}chktexrc}
+ \end{tabularx}
+
+\item Look for it in the current directory. On UNIX boxes,
+ we expect the filename to be \Cmd{.chktexrc}; on other machines
+ \Cmd{chktexrc}.
+
+\end{enumerate}
+
+If you for some reason wish to undo what the previous files may have
+done, you may say \Cmd{CmdLine \{ -g0 -r \}} somewhere in the \rsrc\
+file; this will reset all previous settings.
+
+\subsubsection{Per Line and File Suppressions}
+
+There are many cases in which \chktex{} will give a warning about a
+construct which, although it usually indicates a mistake, is
+intentional. In these cases it can be extremely annoying to have
+this message appear everytime \chktex{} is run. For this reason you
+can use \LaTeX{} comments to suppress a certain message on a single
+line. This can be done by adding a (case-insensitive) comment at the
+end of the line of the form
+\begin{center}
+ \verb+% chktex ##+
+\end{center}
+where \verb+##+ is the number of the message to be suppressed.
+For example the line
+\begin{center}
+ \verb+$[0,\infty)$+\\*
+\end{center}
+will produce a warning (number 9) about mismatched \verb+]+ and \verb+)+.
+However the lines
+\begin{center}
+ \verb+$[0,\infty)$ % chktex 9+\\*
+ \verb+$[0,\infty)$ % ChkTeX 9+\\*
+\end{center}
+will not produce such a message. In this case, message number 17 will
+still appear at the end, stating that the numbers of \verb+]+ and
+\verb+)+ don't match for the entire file.
+
+To suppress two different errors on the same line you will need two
+instances of \verb+chktex+ in the comment. This format is a little
+cumbersome, but it shouldn't be needed often, and hopefully will help
+avoid accidental suppressions.
+\begin{center}
+ \verb+Jordan--H\"older on $[0,\infty)$ % chktex 8 chktex 9+\\*
+\end{center}
+
+One problem inherent in line-by-line suppressions is that during editing
+another error of the same type may creep into the same line. Therefore,
+I suggest using the \texttt{-L} or \texttt{-{}-nolinesupp} option to
+disallow line based suppressions once just before the document is finished.
+At that point you should go back over all the warnings and decide if they
+should be fixed.
+
+In addition to line-specific suppressions, you can create a suppression which will be in effect for the remainder of the file.
+This can be used, for example, to turn off warning 18 (about \verb+"+) in a file which uses a package (like \Cmd{babel}) where \verb+"+ is an active character.
+The syntax is nearly the same, namely
+\begin{center}
+ \verb+% chktex-file ##+
+\end{center}
+
+\subsubsection{Hints}
+I've tried to collect some advice that may be useful --- if you have a
+favourite hint, feel free to send it to me!
+
+\begin{itemize}
+\item If you use \Cmd{german.sty} or several of \Cmd{babel} languages
+ which use \verb+"+ as an active character; it may be wise to put \Cmd{-n18} in
+ the \Cmd{CmdLine} entry in the \rsrc\ file. This will probably reduce
+ the amount of false warnings significantly. Alternately, you can put
+ \verb+% chktex-file 18+ in your files which use one of these packages so
+ that other files will still have these checks performed.
+\item Put \Cmd{-v} in the \Cmd{CmdLine} entry of the \rsrc\ file; this
+ makes the fancy printing the default.
+\item If you're working on a large project, it may pay off to make a
+ local resource file which is included in addition to the global
+ one. In this one, add the necessary info to reduce the amount of
+ false warnings --- these usually don't do anything but hide the
+ real warnings.
+\item Create a total ignore environment, which \chktex\ will ignore
+ completely. In here, you can place all that code which outsmarts
+ \chktex\ completely. For instance, add the following lines at the top
+ of your \LaTeX\ file:
+\begin{verbatim}
+% ChkTeX will ignore material within this environment
+\newenvironment{ignore}{}{}
+\end{verbatim}
+ In addition, you should add the item \Cmd{ignore} to the \Cmd{VerbEnvir}
+ entry in the \rsrc\ file.
+\end{itemize}
+\subsubsection{Bugs}
+
+No fatal ones, I think, but the program currently has some problems when a
+\LaTeX\ command/parameter stretch over a two lines --- some extra spaces
+may be inserted into the input. I regard the program as fairly well
+tested; using the SAS/C \Cmd{cover} utility I was able to make sure that
+approximately 95\% of the code has actually been run successfully in the
+final version. This does indeed leave some lines; most of these are
+procedure terminating brackets or ``can't happen'' lines, though.
+
+We've got some problems when isolating the arguments of a command.
+Although improved, it will certainly fail in certain cases; \chktex\
+can for instance not handle arguments stretching over two lines. This
+also means that \Cmd{WIPEARG} entries in the \rsrc\ file will only
+have the first half of their argument wiped if the argument stretches
+over two lines. We will, however, take care not to wipe parenthesis
+in such cases, in order to avoid false warnings.
+
+Long lines are broken up into chunks and handled separately. The exact
+length is platform dependent, though is guaranteed to be at least 256 bytes.
+The first portions of the line will have line numbers that are 1 less than
+they should be. Some errors can be missed and some can be added erroneously.
+A warning will be issued if lines are too long.
+
+Before submitting a bug report, please first see whether the problem can be
+solved by editing the \rsrc\ file appropriately.
+
+
+
+\subsection{ChkWEB}
+
+This shell script is provided for checking CWEB files. The template is
+as follows:
+\begin{verbatim}
+chkweb [options] file1 file2 ...
+\end{verbatim}
+As you may see from the script, it is only a trivial interface towards
+\texttt{deweb} and \chktex. It does not support any individual options
+on the command line --- all options found will be passed onto \chktex.
+If \Cmd{-{}-} or a filename is found, the remaining parameters will be
+ignored.
+The only real intelligence it features is that it will try to append
+\verb@.w@ to filenames it can't find.
+
+If no filenames are given, we will read from \texttt{stdin}.
+
+\subsection{DeWEB}
+
+This program strips away C code and CWEB commands from CWEB sources.
+It is called with the following synopsis:
+
+\begin{verbatim}
+deweb file1 file2 ...
+\end{verbatim}
+
+\texttt{deweb} filters away all C \&\ CWEB commands from a CWEB source
+code. This leaves only the \LaTeX\ code. This stripped code, in turn,
+may then be passed to a suitable syntax checker for \LaTeX, like
+\chktex\ and \texttt{lacheck}, or spell-checkers like \texttt{ispell}.
+
+When \texttt{deweb} strips away the C code from your CWEB source, it tries to
+preserve line breaks. This means that the error reports from {\it your
+ favorite tool\/} will be correct regarding to line numbers. In most
+cases, the column position will also be correct. This significantly
+simplifies finding the errors in the \LaTeX\ source (in contrast to the
+output from \texttt{cweave}, which output is truly difficult to figure
+anything out from).
+
+\texttt{deweb} accepts a list of filenames on the argument line, and will send
+its output to \texttt{stdout}. If no filenames are given, it will read from
+stdin, acting as a filter. No options are currently accepted.
+
+Macho users may try to pipe the output from \texttt{deweb} directly into
+\LaTeX, theoretically, this should work. This would ease the debugging of
+the \LaTeX\ code significantly, as when \LaTeX\ complains about wrong
+syntax, you'll be able to find the erroneous line much more easily. Don't
+expect that the output looks very much like the final one, though.
+
+\texttt{deweb} should now understand all correct \texttt{CWEB} opcodes. If it
+complains about not understanding a correct opcode, please inform the
+author.
+
+\subsubsection{Bugs}
+
+\texttt{deweb} will not even \emph{compile} under Perl versions before perl
+v5. Unfortunately, this means that we can't even tell the user why we
+failed; Perl will just complain about not being able to compile the
+regexps.
+
+\section{Explanation of error messages}
+Below is a description of all error-messages \chktex\ outputs.
+Error messages set in {\it italic type\/} are turned off by default.
+Where margin paragraphs are listed in the text, they refer to the
+keyword in the \rsrc\ file which controls the discussed warning.
+
+\newcommand\Keyword[1]{\marginpar{\texttt{\hfill\\ #1}}}
+
+\smallskip\pagebreak[2]
+\Keyword{Silent}
+\begin{errdesc}{Command terminated with space.}
+ You tried to terminate a command with a blank space. Usually, this

+
+ If they are of the same type, \chktex\ will determine which keyword

+ Number & \texttt{NumDash} \\*
+ Alphabetic character & \texttt{HyphDash} \\*
+ \end{tabular}
+
+ This is more or less correct, according to my references. One
+ complication is that most often a hyphen (single dash) is desired
+ between letters, but occasionally an n-dash (double dash) is
+ required. This is the case for theorems named after two people
+ e.g.\ Jordan--H\"older. A hyphen would indicate that it was one
+ person with a hyphenated name e.g.\ Gregorio Ricci-Curbastro.
+ If this is rare enough, it can be dealt with via line based suppressions.
+ However, exceptions can also be handled by adding them to the
+ \texttt{DashExcpt} list. The ``words'' in this list are
+ considered to be correct regardless of any other settings.
+ Adding \verb+Jordan--H\"older+ to this list will cause no warning
+ to be issued. There is still the problem that no warning will be
+ raised for Jordan-H\"older (unless added explicitly via regular
+ expression), so care must still be taken.
+
+ Some manuals---particularly American manuals---also suggest
+ \emph{not} adding space around an m-dash (triple dash).

+
+ An example, included in the \rsrc\ file, is given below. Remember that you
+ have to escape (with~\verb+!+) spaces and \verb+#+ as well as a few other
+ characters. One should always use \verb+\nmid+ instead of \verb+\not\mid+
+ because the results are much better.
+ \begin{errexam}
+ \verb+\\not! *(\||\\mid)+\\*
+ \verb+User Regex: \not\mid.+\\*
+ \end{errexam}
+ or with an initial comment
+ \begin{errexam}
+ \verb+(?!#Always! use! \nmid)\\not! *(\||\\mid)+\\*
+ \verb+User Regex: Always use \nmid.+
+ \end{errexam}
+
+ You can use \verb+% chktex 44+ to suppress user regular expression
+ warnings on a given line, but this is often undesirable since all such
+ warnings are suppressed this way. For this reason you can ``name'' user
+ regular expression warnings with negative numbers. For example
+ \verb+% chktex 4+ will suppress the system warning number 4, but
+ \verb+% chktex -4+ will suppress the user regular expression warning
+ number 4. Since one might wish to add, remove, or rearrange user warnings
+ in the \rsrc\ file, you must explicitly name particular warnings rather
+ than relying on position in that file.
+
+ In order to name one, include an initial PCRE-style comment with the first
+ characters being a number (positive or negative---the absolute value will
+ be used). The numbers are limited by the number of bits in a \texttt{long},
+ usually giving 1--63 as possible names. You can give more than one regular
+ expression the same name, and suppressing that name will suppress all
+ regular expressions with that name.
+
+ Using the example from before, all of the following will be suppressed with
+ \verb+% chktex -4+. Note that the name \emph{will} be printed as written
+ so that you know which number to suppress.
+ \begin{errexam}
+ \verb+(?!#4:Always! use! \nmid)\\not! *(\||\\mid)+\\*
+ \verb+(?!#-4Always! use! \nmid)\\not! *(\||\\mid)+\\*
+ \verb+(?!#-4! Always! use! \nmid)\\not! *(\||\\mid)+\\*
+ \end{errexam}
+\end{errdesc}
+
+\begin{errdesc}{Use \textbackslash[ ... \textbackslash] instead of \$\$ ... \$\$.}
+
+ In \LaTeX\ documents, using \verb+\[...\]+ is strongly preferred over \verb+$$...$$+.
+ This is because using \verb+$$+ will change the vertical spacing in the
+ equations making them inconsistent.
+
+\end{errdesc}
+
+\begin{errdesc*}{Use \textbackslash( ... \textbackslash) instead of \$ ... \$.}
+
+ In \LaTeX\ documents using \verb+\(...\)+ is slightly preferred over \verb+$...$+.
+ Some error messages might be clearer with \verb+\(...\)+.
+
+\end{errdesc*}
+
+\section{Future plans}
+
+In a somewhat prioritized sequence, this is what I'd like to put into the
+program --- if I have the time.
+
+\begin{itemize}
+\item De-linearize the checker. Currently, it works on a line-by-line
+ basis, in most respects, at least. I hope to be able to remove this
+ barrier; as this will reduce the amount of false warnings
+ somewhat.
+
+\item Probably some more warnings/errors; just have to think them out
+ first. Suggestions are appreciated --- I've ``stolen'' most that
+ similar programs provides, and am running out of ideas, really.
+
+ It would also be nice to investigate the field of ``globally''
+ oriented warnings; i.e.\ warnings regarding the document as a
+ whole. Currently, \chktex\ operates mainly on a local/``greedy''
+ basis.
+
+ If you have suggestions/ideas on this topic, they're certainly
+ welcome, including references to literature.
+
+\item Fix a few more bugs.
+\end{itemize}
+
+\section{Notes}
+
+\subsection{Wish to help?}
+
+As most other living creatures, I have only a limited amount of time. If
+you like \chktex\ and would like to help improving it, here's a few things
+I would like to receive. The following ideas are given:
+
+\begin{itemize}
+\item Does anyone have a $\mbox{\LaTeX}\rightarrow \mbox{\texttt{troff}}$
+ conversion program? It would be really nice if I could extract the
+ relevant sections from this manual, and present them as a man page.
+ I will not, however, convert this manual to \TeX{}info in order to
+ be able to do this; IMHO \TeX{}info documents have far too limited
+ typographic possibilities.
+
+ This doesn't mean that I'm not willing to restructure the document
+ at all. This manual already uses some kind of preprocessing in order
+ to achieve HTML output via \LaTeX2\texttt{html}, I'm willing to do the
+ same in order to produce \texttt{troff} output.
+
+\item Help me port the program! This is a prioritized one. It's no fun
+ writing ANSI C when people haven't got a C compiler.
+
+ Of course, I'll provide whatever help necessary to modify the sources
+ to fit to the new platform. Take contact if you're interested. I will
+ include your compiled binary in the distribution, and give you
+ credit where appropiate.
+
+ Just one request: If you have to modify the sources in order to make
+ \chktex\ compile \& work on the new platform, \emph{please} enclose your
+ changes in something like \Cmd{\#ifdef \_\_PLATFORM\_\_\dots code\dots\#endif}!
+ It makes life so much easier later, when we try to merge the two
+ source trees.
+
+\item Reports on problems configuring and compiling \chktex\ on supported
+ (and unsupported) systems are welcomed.
+
+\item Filters for other file formats. I do believe that there are
+ several formats using \LaTeX\ for its formatting purposes, combining
+ that with something else. If you can write a program or script which
+ filters everything away but the \LaTeX\ code, it will surely be
+ appreciated (and included). Look at the \verb@deweb@ script to see
+ what I mean.
+
+\item Interfaces for other editors are also welcomed.
+
+\item If you update the \rsrc\ file in anyway that is not strictly
+ local, I would appreciate to receive your updated version.
+
+\item Suggestions for new warnings are always welcomed. Both formal
+ (i.e.\ regexps or similar) and non-formal (plain English) descriptions
+ are welcomed.
+\end{itemize}
+
+Of course, people doing any of this will be mentioned in this document, and
+thus receive eternal glory and appreciation.
+
+\subsection{Caps and stuff}
+
+Where trademarks have been used, the author is aware of that they
+belong to someone, and has tried to stick to the original caps.
+
+\section{About the author}
+
+A quick summary of who I am and what I do:
+
+I'm 21 years old, and live in Oslo, the capital of Norway. I'm
+currently studying maths and computer science at the
+University~of~Oslo; planning to get a degree within mathematical
+modeling, with a dash of physics and emphazing the computer part of
+the study. More precisely, in autumn'96 my studies consist of
+mathematical analysis, statistics \& probability calculations plus
+studying the relationship between society and computers.
+
+At home I now possess 4 computers, of which 1 is regular use: A
+vanilla Amiga 1200, expanded only by a HD\@. The others are a
+\texttt{80286} PC and an Amiga 500, both semi-out-of-order. The last
+one is a Commodore VIC-20, which for some peculiar reason never seems
+to be used. Plans are to get a Linux-capable PC, though.
+
+Most of the time in front of these computers (including SGI Indy's and
+SPARC stations at our university) is spent on C and shell programming,
+plus some text-processing.
+
+ % I am also involved in writing the document
+ % for {\sc Isaac} --- Interactive Simulation as an Alternative to
+ % Advanced Calculations. This is planned to help newcomers to physics,
+ % by providing a computer program which enables one to simulate most
+ % experiments relating to classical mechanics.
+ %
+
+C and shell programming are not my only knowledge areas regarding
+computers, however. I write the following languages more or less:
+Perl, Motorola \texttt{68000} assembly code, ARexx, Simula, C++, \LaTeX,
+HTML, AmigaGuide, Amos Basic and Installer LISP\@. Once I also
+mastered Commodore Basic V2, the ``language'' included with my VIC-20.
+
+However, I also try to not to end up as a computer nerd. Thus, in
+addition to the compulsory (?) interest for computers, I am a scout.
+Still running into the woods, climbing the trees, falling down and
+climbing up once more, in other words. To be more specific, I am a
+now a troop leader for `Ulven' scout-group; Norwegian Scouts
+Association. I am also a active rover in `V{\aa}lerenga' scout-group.
+
+Certainly a lot more to tell (I play the piano and like cross-country
+skiing, for instance); but I'll stop here before you fall
+asleep\dots

+
+ \Name{Russ Bubley}{russ@scs.leeds.ac.uk}
+ He has been the main external beta-tester for this program, sending
+ me loads and loads of understandable and reproducible bug reports.
+ If you somehow think that \chktex\ is well-behaved and free from
+ bugs, send warm thoughts to Russ. He has also provided ideas for
+ enhanced checks and so forth.
+
+ In addition, he sent me a huge list of 238 common English
+ abbreviations, for inclusion in the \rsrc\ file! Together with the
+ enhanced abbreviation recognizer, I do now believe most
+ abbreviations should be caught\dots
+
+ Finally, he has also given me valuable hints for improving the
+ program's outputting routine, and given me lots of suggestions for
+ filtering unnecessary/false warnings away.
+
+ \Name{Gerd B\"ohm}{Gerd.Boehm@physik.uni-regensburg.de}
+ Improved and bug-fixed the MS-DOS port of \chktex\ v1.4, sending me
+ ready-to-yank code patches. The original port didn't respect all
+ the peculiarities of the MS-DOS file-system, unfortunately.
+
+ \Name{Antonio DiCesare}{dicesare@vodafone.it}
+ He provided many feature requests and bug reports for the 1.7.1
+ version making it a much better release than it would have otherwise
+ been. He also helped expand several keywords in the \rsrc\ file.
+
+ \Name{Mojca Miklavec}{mojca.miklavec.lists@gmail.com}
+ Found and helped debug a problem (fixed in 1.7.2) occurring only on
+ some platforms, 32 bit Macs for one.
+
+ \Name{Baruch Even}{chktex@ev-en.org}
+ Maintainer of \chktex\ for about a decade.
+
+ \Name{Lars Frellesen}{frelle@math-tech.dk} Sent a few bug reports
+ regarding the filtering of messages. He has also helped me to
+ expand the \Cmd{SILENT} keyword in the \rsrc\ file.
+
+ \Name{Wolfgang Fritsch}{fritsch@hmi.de}
+ Author of the OS/2 port, which he did using the emx compiler.
+ Please direct questions regarding strictly to that port to him (I
+ would like to receive a carbon copy, though).
+
+ \Name{Stefan Gerberding}{stefan@inferenzsysteme.informatik.th-darmstadt.de}
+ First one to report the Enforcer hit in v1.2 when using \chktex\ as
+ a pipe. Also came with suggestions to make \chktex\ more easily
+ compile on early gcc compilers.
+
+ He has also kept on beta-testing later versions of \chktex, giving
+ me bug-reports and enhancements requests.
+
+ \Name{Kasper B. Graversen}{kbg2001@internet.dk} Lots of creative
+ suggestions and improvements. Several of the warnings implemented
+ were based on his ideas. In addition, he has given advice for
+ improving the existing warnings.
+
+ Has also provided some OS-oriented code.
+
+ \Name{Frank Luithle}{f\_luithle@outside.sb.sub.de}
+ Wrote a translation for v1.0. Unfortunately, he remained unreachable
+ after that\dots:-/
+
+ \Name{Nat}{nat@nataa.frmug.fr.net}
+ Reported the same bug as Gerberding. In addition, he taught me a
+ few tricks regarding the use of gcc + made me understand that the
+ ANSI standard isn't unambigious; at least the \verb@getenv()@ call
+ seem to be open for interpretations. Many possible
+ incompatibilities have been removed due to these lessons.
+
+ \Name{Michael Sanders}{sanders@umich.edu}
+ Has found some of the bugs in this beast; both obscure and
+ long-lived. Has also provided motivation to clarify this document.
+
+ \Name{Bj\o rn Ove Thue}{bjort@ifi.uio.no}
+ Author of the MSDOS port; please direct questions regarding
+ strictly to that port to him (I would like to receive a carbon
+ copy, though).
+
+ \Name{Martin Ward}{Martin.Ward@durham.ac.uk}
+ Sent a few bug-reports; also gave me information upon where to find
+ regexp code. He also provided a Perl script for checking ordinary
+ text, which ideas I was able to implement in \chktex. In addition,
+ he sent me the source code for \verb@lacheck@; which also inspired some
+ of the warnings.

+Development of ChkTeX is now in a maintainance mode. All versions
+1.6.x are essentially bug fixes. Version 1.7 added some new features.
+
+1.7.6 (2016-09-09), released by Ivan Andrus <darthandrus@gmail.com>
+
+ * Properly copy and free strings. This caused incorrect file
+ reporting in some cases #49000
+ * Add "verbatim" commands and environments from tipa #46734
+ * Avoid infinite loop when a regex matches an empty string
+ * Fix crash on invalid regular expression
+ * Add warnings for $$...$$ and $...$ #47044
+ * Update the banner to reflect current bug reporting contacts
+
+1.7.5 (2015-12-07), released by Ivan Andrus <darthandrus@gmail.com>
+
+ * Track whether the previous line ended in a comment #45980
+ * Add a few source code environments to VerbEnvir
+ * Don't show long line warning if the last line doesn't have a newline #46539
+ * Fix deweb's handling of file names #46043,#46042
+ * Use the exit status to indicate warnings were found #45979
+ * Consider OS X a UNIX
+
+1.7.4 (2015-04-11), released by Ivan Andrus <darthandrus@gmail.com>
+
+ * Fixed undefined behavior (patch from TeXLive)
+
+1.7.3 (2015-04-09), released by Ivan Andrus <darthandrus@gmail.com>
+
+ * Fixed memory leaks and a crashing bug #42813
+ * Added ConTeXt \start... \stop... tracking #44517
+ * Added DashExcpt list for exceptions to dash rules #42237
+ * Support \cite with two optional arguments (biblatex) #44413
+ * Removed warning about using \dots instead of .. #40731
+ This incorrectly warns about relative paths
+ * Removed check for intro since it's common in file names #43013
+ * Turn off warning 19 by default #44226
+ Warning 19 is about Latin-1 quotes, but gives false positives
+ for some utf-8 characters.
+
+1.7.2 (2013-04-17), released by Ivan Andrus <darthandrus@gmail.com>
+
+ * Fixed display bug on platforms where sizeof(int) != sizeof(regoff_t)
+ * Warn that .. should be \dots like lacheck does
+ * Fixed warnings under clang
+ * Incorporated several build related patches from TeX Live
+
+1.7.1 (2012-08-22), released by Ivan Andrus <darthandrus@gmail.com>
+
+ * Improvements for TeX Live and CTAN
+ * Fixed bug when checking for interword spacing
+ * Added warning when a file has lines that are too long which can cause problems
+ * Added ability to suppress user regular expression warnings by "naming" them
+ * Added ability to suppress warnings for the rest of the file
+ * Allow using PCRE or POSIX ERE or neither (at configure time).
+ Regular expressions can be marked as PCRE or POSIX only.
+ * Allow () to specify an optional argument in WipeArg to support \cmidrule[](){}
+ * Allow regular expressions for Silent keyword, specified in [] for "case insensitive"
+ * Added warning about \hline and vertical rules in tabular environments
+ * I changed user warnings to be post WipeArg (like they were pre
+ 1.7.0). I had changed them in 1.7.0 to be pre WipeArg so that I
+ could match things like \label{...}, but this caused many false
+ positives by matching in comments, etc.
+
+1.7.0 (2012-05-28), released by Ivan Andrus <darthandrus@gmail.com>
+
+ * Added support for user defined regular expression based warnings
+ * Added support for macros like \ensuremath and \text
+ * Added support for suppressing messages on a single line
+
+1.6.6 (2012-04-07), released by Ivan Andrus <darthandrus@gmail.com>
+
+ * Fixed some memory issues
+ * Do not increase line number when the line was very long
+ * Some fixes for TexLive
+
+1.6.5 (??), released by Jean-Marc Lasgouttes <lasgouttes@lyx.org>
+
+ * Fix bug where ChkTeX generates a warning about missing space before
+ parenthesis when the parenthesis is at start of line.
+ * Update ChkTeX.tex.in to use proper LaTeX2e markup.
+ * Update the build machinery a bit.
+
+1.6.4 (2007-10-20), released by Baruch Even
+
+ * For some reason 1.6.3 did not include all the changes it was supposed to
+ have, this release should fix it. One such issue is the MacOS X
+ compilation.
+ * Include some updates to the default chktexrc from Jean-Marc Lasgouttes.
+
+1.6.3, released by Baruch Even
+
+ * Support DESTDIR for installation to help distributions.
+ * Apply old standing patch from Jean-Marc Lasgouttes to compile outside the
+ directory.
+ * Enable compilation on MacOS X.
+ * Fix various coding issues.
+
+
+Original versions from Jens T. Berger Thielemann:
+=================================================
+
+Modifications and additions since v1.6:
+
+ * Improved the build system
+ * Better fixes for memory access errors
+
+Modifications and additions since v1.5:
+
+ * Fixed a crash when running from emacs
+ * Fixed a crash when checking our own manual
+ * Added \verb* support
+
+Modifications and additions since v1.4:
+
+ ** New warnings
+
+ * No space or similar in front/after parenthesis.
+ * Demands a consistent quote style.
+ * Double spaces in input which will not be rendered as one.
+ * Punctuation malplaced regarding to math mode.
+ * Warns about TeX primitives.
+ * Space in front of footnotes.
+ * Bogus \left and \right commands.
+
+ ** Program
+
+ * The abbreviation recognizer has (for the last time?) been
+ redesigned. We now produce far less false warnings, catch more
+ cases and do all this faster than before. Seems like a win. Done
+ much of the same with the italic correction detection part,
+ too.
+ * Some bugs have been silently fixed. Hot spots in the program have
+ been optimized; in certain cases this in fact doubles the speed!
+ * Along with this goes more code elegance and utilization of macro
+ processing and the C language. Take a look at Resource.[ch].
+
+ * It's possible to specify separate output-formats depending on
+ whether you are sending the output to a file/pipe or to a
+ terminal.
+
+ * Column positions are finally correct; we now expand tabs
+ correctly.
+ * ChkTeX will now recursively search for \input'ed
+ files, both in the document and on the commandline. See the
+ chktexrc file for more info.
+ * The debug switch is now more intelligent; if you wish to hack
+ a bit on ChkTeX for yourself, it is possible to produce
+ selective debugging output. The feature can also be disabled
+ altogether.
+ * MS-DOS and OS/2 version of the program is now more flexible
+ and well-behaved, thanks to Gerd Boehm.
+ * You may now say -wall to make all messages warnings, and
+ turn them on.
+ * Uses termcap on UNIX boxes; this should ensure that -v2
+ (or more precisely: %i and %I works regardless to
+ what terminal you are using.
+
+ ** Resource file
+
+ * You may now specify both case-sensitive and case-insensitive user
+ patterns in the chktexrc file. In addition; it is now possible to
+ reset/clear lists.
+ * You can now specify how many optional or required arguments
+ WIPEARG should wipe; it also behaves somewhat more intelligently
+ when the arguments stretch over multiple lines.
+ * Global files will be read in addition to local ones. The searching
+ order has also been reversed in order to make this more
+ intelligent.
+
+ ** Other
+
+ * The documentation has been polished and should now be easier
+ to use in practical situations.
+ * check target in Makefile, so you can check that the installation
+ succeeded. In fact, the Makefile has been enhanced in several other
+ ways too, amongst other it is now GNU conforming.
+ * deweb is now documented; you may say "man deweb" to get a few
+ words of advice. The support script (chkweb) does now behave as the
+ remaining package (accepting stdin input and flags).
+ * I've written an Emacs hack which magically adds ChkTeX to the list
+ of AUC-TeX commands; thus making the use of the program even more
+ trivial. For those of you who don't wish to mess with Emacs, I've
+ included a trivial lacheck <-> ChkTeX interface. This means that you
+ now can use ChkTeX just as easily as lacheck when you're running
+ AUC-TeX.
+ * Added an ARexx script which lets ChkTeX talk to VBrowse, the
+ message browser of Volker Barthelmann's freely distributable ANSI
+ C compiler. The browser itself is available on Aminet as
+ dev/c/vbcc.lha.

+ChkTeX
+======
+
+ChkTeX is a tool to check for common errors in LaTeX files. It also
+supports checking CWEB files (uses a perl5 script). It is highly
+customizable allowing you turn off any warnings you don't like, as
+well as add your own warnings. It works easily with Emacs and AUCTeX,
+but should also be easy to interface with other editors. If you have
+interfaced ChkTeX with another editor, please contribute how you did
+it.
+
+It is important to remember that ChkTeX is only intended as a *guide*
+to fixing faults. It is by no means always correct. This means that
+correct LaTeX code may produce errors in ChkTeX, and vice versa:
+incorrect LaTeX code may pass silently through. If you have ideas for
+new warnings or ways in which current warnings could be improved,
+please report them on the
+[bug tracker](https://savannah.nongnu.org/bugs/?group=chktex).
+
+For complete documentation see [the manual](http://www.nongnu.org/chktex/ChkTeX.pdf).

+#####################################################################
+#
+# Note: The format has changed slightly (again). The { ... }
+# syntax does now mean case-sensitive comparing, while [ ... ] means
+# case-insensitive comparing of the keywords. Case-insensitive
+# comparing of the keywords is only supported on a few of the
+# keywords (it's not meaningful in all contexts, and it slows ChkTeX
+# down). Keywords supporting this are marked throughout the file.
+#
+# You may also reset a list by saying "KEYWORD = { ... }"; it will
+# then be set equal to the contents of the list you specify.
+#
+# Comments begin with `#', and continues for the rest of the line.
+# Blank lines plus leading and trailing spaces are of course ignored.
+#
+# The general format of this file is the following:
+#
+# KEYWORD { item item ...} [ item item ... ] /* Adds items */
+#
+# KEYWORD [ item item ...] { item item ... } /* Adds items */
+#
+# KEYWORD = item
+#
+# KEYWORD = { item item ... } /* Clears list before adding */
+#
+# KEYWORD = [ item item ... ] /* Clears list before adding */
+#
+# This does _not_ mean that you may alternate the forms; certain
+# keywords demands a list, other a single value. You thus have to
+# look at the examples of their use.
+#
+# Please also note that if you specify a list-keyword twice, we'll
+# concatenate the lists. If you specify a item-keyword twice, we'll
+# kill the previous value.
+#
+# We are slightly context-sensitive when detecting tokens like "}"
+# and "]"; they have to be preceded by a space. This generally makes
+# life easier.
+#
+# Items are separated by spaces. Newlines are considered as spaces,
+# but can't be escaped. You may surround items with quotes (`"') to
+# easily put spaces into them.
+#
+# Escape sequences available:
+#
+# Sequence Resulting character
+# ! A space (type `! ', not just a exclamation mark)
+# !" "
+# !# #
+# !! !
+# !{ {
+# !} }
+# ![ [
+# !] ]
+# != =
+# !b Backspace
+# !n New line
+# !r Carriage return
+# !t Tab
+# !f Form feed
+# !xNN NN must be a hexadecimal number (00 - ff),
+# _both_ characters must be included.
+# !dNNN DDD must be a decimal number (000 - 255), all
+# three characters must be included. Unspecified
+# results if DDD > 255.
+# !NNN DDD must be a octal number (000 - 377), all
+# three characters must be included. Unspecified
+# results if DDD > 377.
+#
+# Minor note: As you can see, most of these escape sequences are
+# equal to those in C (with some extensions); however, we use !
+# instead of \ as escape character for obvious reasons.
+#
+#
+# Quick summary of keywords follows. Keywords marked with a * accept
+# keywords accepting case-insensitive lists.
+#
+# Abbrev* - A list of abbreviations not automatically caught.
+# CenterDots - Commands/characters which should have \cdots in
+# between.
+# CmdLine - Default commandline options. These will be
+# processed before the ones you give on the command
+# line.
+# HyphDash \
+# NumDash - Number of dashes allowed in different contexts.
+# WordDash /
+# IJAccent - Commands which puts an accent _over_ their
+# argument.
+# Italic - Commands immediately turning on italic mode.
+# ItalCmd - Commands putting their argument into italic.
+# Linker - Commands which should have a non-breaking space in
+# front.
+# LowDots - Commands/characters which should have \ldots in
+# between.
+# MathEnvir - Environments which turn on math mode.
+# MathCmd - Commands which turn on math mode.
+# TextCmd - Commands which turn off math mode.
+# MathRoman - Mathematical operators with LaTeX replacement
+# defined.
+# NoCharNext - Insists on that certain commands aren't followed by
+# certain characters.
+# NonItalic - Commands immediately turning off italic mode.
+# NotPreSpaced- Commands which should not have a space in front of
+# them.
+# Primitives - Primitive TeX commands.
+# PostLink - Commands which generates a page reference.
+# OutFormat - Formats to use for output. See the -f & -v switch
+# in the main doc.
+# QuoteStyle - Either "Traditional" or "Logical". See main doc,
+# warning 38.
+# Silent - These commands do not produce any textual output;
+# and are thus allowed to have a space after them.
+# TabSize - Tab size you are using.
+# TeXInputs - Paths to search \input and \include files for.
+# UserWarn* - These strings will be searched for throughout the
+# text.
+# VerbEnvir - Environments which contents should be ignored.
+# VerbClear - String we will overwrite unwanted data with.
+# WipeArg - Commands (with arguments) which should be ignored
+# in the checking.

+# Here, you can specify the length of various dashes. We sort the
+# dash according to which type of characters that are on the left and

+# We associate as follows:
+#
+# Name Type of character on each side
+# HyphDash Alphabetic (foo-bar)
+# NumDash Numeric (2--3)
+# WordDash Space (like this --- see?)
+#
+# Below you specify how many dashes which are legal in each case. We
+# define 0 as a magic constant which always generates an error. You
+# may specify more than one legal dash-length.
+#
+# Let's look at an example. You use the following dash-syntax:
+#
+# foo-bar
+# 2--3
+# like this---see?
+#
+#
+# HYPHDASH { 1 3 } # Either a hyphen, or inter-word

+.TH deweb 1 "June 8, 1996"

+.SH NAME
+deweb \- strips away C & CWEB commands from CWEB sources
+.SH SYNOPSIS
+.B deweb
+[
+.B file1 file2 ...
+]
+.SH DESCRIPTION
+.I deweb
+filters away all C & CWEB commands from a CWEB source code. This
+leaves only the
+.I LaTeX
+code. This stripped code, in turn, may then
+be passed to a suitable syntax checker for LaTeX, like
+.I ChkTeX
+and
+.I lacheck,
+or spell-checkers like
+.I ispell.
+.PP
+The
+.I chkweb
+tool, included in the
+.I ChkTeX
+distribution will do just this; writing similar scripts should be
+trivial.
+.PP
+When
+.I deweb
+strips away the C code from your CWEB source, it tries to preserve line breaks.
+This means that the error reports from
+.I <your favorite tool>
+will be correct regarding to line numbers. In most cases,
+the column position
+will also be correct. This significantly simplifies
+finding the errors in the
+.I LaTeX
+source (in contrast to the output from
+.I cweave,
+which output is truly difficult to figure anything out from).
+.PP
+.I deweb
+accepts a list of filenames on the argument line, and will send its output
+to
+.I stdout.
+If no filenames are given, it will read from stdin, acting as
+a filter. No options are currently accepted.
+.PP
+Macho users may try to pipe the output from
+.I deweb
+directly into
+.I LaTeX,
+theoretically, this should work. This would ease the debugging
+of the
+.I LaTeX
+code significantly, as when
+.I LaTeX
+complains about wrong syntax, you'll be able to find the erroneous
+line much more easily. Don't expect that the output looks very much
+like the final one, though.
+.PP
+.I deweb
+should now understand all correct
+.I CWEB
+opcodes. If it complains about not understanding a correct opcode,
+please inform the author.

+.B cweave(1), perl(1), chktex, lacheck(1), ispell(1)
+.SH BUGS
+Doesn't even
+.B compile
+under
+.I Perl
+versions before perl v5. Unfortunately, this means that we can't even
+tell the user why we failed;
+.I Perl
+will just complain about not being able to compile the regexps.
+.PP
+The program will try to swallow the whole input file at once, instead of
+processing it on a line\-by\-line basis.

+# SYNOPSIS
+#
+# AX_CFLAGS_STRICT_PROTOTYPES [(shellvar [,default, [A/NA]]
+#
+# DESCRIPTION
+#
+# Try to find a compiler option that requires strict prototypes.
+#
+# The sanity check is done by looking at sys/signal.h which has a set of
+# macro-definitions SIG_DFL and SIG_IGN that are cast to the local
+# signal-handler type. If that signal-handler type is not fully qualified
+# then the system headers are not seen as strictly prototype clean.
+#
+# For the GNU CC compiler it will be -fstrict-prototypes
+# -Wstrict-prototypes The result is added to the shellvar being CFLAGS by
+# default.
+#
+# DEFAULTS:
+#
+# - $1 shell-variable-to-add-to : CFLAGS
+# - $2 add-value-if-not-found : nothing
+# - $3 action-if-found : add value to shellvariable
+# - $4 action-if-not-found : nothing

+\`configure' configures ChkTeX (TeX Live) 1.7.6 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
+ --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
+ --localstatedir=DIR modifiable single-machine data [PREFIX/var]
+ --libdir=DIR object code libraries [EPREFIX/lib]

+ --enable-static[=PKGS] build static libraries [default=yes]
+ --enable-fast-install[=PKGS]

+ --with-gnu-ld assume the C compiler uses GNU ld [default=no]
+ --with-sysroot[=DIR] Search for dependent libraries within DIR (or the
+ compiler's sysroot if not specified).
+ --with-system-kpathsea use installed kpathsea headers and library (requires
+ pkg-config)
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ LT_SYS_LIBRARY_PATH
+ User-defined run-time library search path.
+ CPP C preprocessor
+ LATEX LaTeX command
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it. You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations
+below.
+
+ When we speak of free software, we are referring to freedom of use,
+not price. Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+^L
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it
+becomes a de-facto standard. To achieve this, non-free programs must
+be allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+^L
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control
+compilation and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+^L
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+^L
+ 6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at least
+ three years, to give the same user the materials specified in
+ Subsection 6a, above, for a charge no more than the cost of
+ performing this distribution.
+
+ d) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+^L
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+^L
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply, and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License
+may add an explicit geographical distribution limitation excluding those
+countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+^L
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE

+This is the regex functionality from glibc 2.5 extracted into a
+separate library, for Win32. It may be built, from the sources
+provided, using the command sequence:--
+
+ ./configure [--options...] && make
+
+For a list of available configuration options, run:--
+
+ ./configure --help
+
+After building, as above, the resultant DLL, and optionally the
+associated development kit, may be installed by:--
+
+ make install
+
+while redistributable binary DLL and development library kits may
+be created by:--
+
+ make dist

+
+The original port of this functionality was implemented by Tor
+Lillqvist; I've adapted his work, to make it somewhat more MinGW
+friendly. I have *not* modified any of the `C' sources provided
+by Tor; nor have I changed the naming conventions he adopted for
+generated distributables. I *have*:--
+
+1) Replaced Tor's original `Makefile' with an autoconf generated
+ configure script, and a backwardly compatible `Makefile.in';
+ this provides a more flexible build procedure, which I find
+ more convenient, when cross-compiling on a GNU/Linux host.
+
+2) Added VPATH support, for `out of tree' builds.
+
+3) Adapted the build procedure, to avoid a dependency on the `lib'
+ program from Microsoft's MSVC tool chain. This is achieved by
+ providing an option to configure, which is disabled by default;
+ it may by activated by specifying `--enable-msvc-implib' on the
+ configure command line. If this option is not activated, or if
+ the MSVC `lib' tool is not present, the Makefile is configured
+ without binding the rule for building an MSVC compatible import
+ library, to the default target, (although the rule is left in
+ place for explicit use).
+
+ If the `--enable-msvc-implib' option is specified, but `lib' is
+ not present, then configure will issue a warning message, and
+ will again configure the Makefile without binding this rule to
+ the default target.
+
+ Only if the `--enable-msvc-implib' option is specified, *and*
+ the `lib' tool is present, will building of an MSVC compatible
+ import library be configured as a default deliverable.
+
+4) Added `install', `install-dll' and `install-dev' targets, to
+ support direct installation of the DLL, and its associated
+ development kit.
+
+5) Changed the default packaging format for distributables, from
+ Tor's exclusive choice of `zip', to my own preferred `tar.gz';
+ `zip' format remains available, as an option, by configuring
+ with `--enable-dist=zip'.
+
+6) Added `bindist', `devdist' and `srcdist' targets, for greater
+ flexibility in building distribution kits.
+
+The original text of Tor's README file will be found below.
+
+--Keith Marshall <keithmarshall@users.sourceforge.net>
+
+I call the DLL libgnurx-0.dll which hopefully should be unique. At
+least it isn't "regex.dll" which has been used by the
+gnuwin32.sourceforge.net site for *two* incompatible DLLs. (That mess,
+and the mess with their build of Henry Spencer's regex library, was
+what lead me to build my own GNU regex library. See the
+gnuwin32-users mailing list archives from December 2006.)
+
+The "-0" is so that if at some point I build a release that isn't
+binary compatible, I can then increment that and use a different name.
+
+The import library for gcc is called libgnurx.dll.a, but I also
+distribute a copy of it called libregex.a so that configure scripts
+that look for -lregex will work.
+
+Note that none of the wide-character and i18n functionality which is
+built when this is part of glibc gets compiled. Thus things like
+character classes most probably work only for single-byte codepages.
+
+Compiling that stuff would drag in lots of glibc's locale handling
+stuff which is completely incompatible with Microsoft's C library's
+locale handling anyway. Also, I am not sure whether the GNU regex code
+is prepared to handle a two-byte wchar_t, or does it assume that
+wchar_t is int as it is on Linux? Hmm, actually there is lots of
+sizeof(wchar_t) in glibc, so maybe it *is* prepared? Maybe
+later... But anyway, it would presumably mean we should have not just
+the regex functionality but a larger subset of glibc that would
+include all locale, ctype, wchar, mbs, etc stuff, presumably ending up
+with a very large part of glibc (not the system calls,
+obviously). Indeed, something to save for later, or never...

+ the first STOP characters of the concatenation of the strings should be
+ concerned.
+
+ If REGS is not NULL, and BUFP->no_sub is not set, the offsets of the match
+ and all groups is stroed in REGS. (For the "_2" variants, the offsets are
+ computed relative to the concatenation, not relative to the individual
