+# 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

+
+           Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+                    675 Mass Ave, Cambridge, MA 02139, 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
+
+           Appendix: 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>
+
+    This  program  is  free software; you can redistribute it and/or modify it
+    under the terms of the GNU General Public License as published by the Free
+    Software  Foundation; either version 2 of the License, or (at your option)
+    any later version.
+
+    This  program  is  distributed  in  the  hope  that it will be useful, but
+    WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY
+    or  FITNESS  FOR A PARTICULAR PURPOSE.  See the GNU General Public License
+    for more details.
+
+    You  should  have  received a copy of the GNU General Public License along
+    with  this  program;  if not, write to the Free Software Foundation, Inc.,
+    675 Mass Ave, Cambridge, MA 02139, 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

+
+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 {\em
+  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.
+Software is provided for beautifully interfacing against the 
+AUC-\TeX\ Emacs mode, CygnusED, GoldEd and various Amiga message browsers.
+
+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.
+
+\subsection{New features}
+
+Modifications and additions since v1.6:
+\begin{itemize}
+  \item Improved the build system
+  \item Better fixes for memory access errors
+\end{itemize}
+
+Modifications and additions since v1.5:
+\begin{itemize}
+  \item Fixed a crash when running from emacs
+  \item Fixed a crash when checking our own manual
+  \item Added \tt{\BS{}verb*} support
+\end{itemize}
+
+Modifications and additions since v1.4:
+
+\subsubsection{Program}
+
+Modifications to the executable itself:
+\begin{itemize}
+\item As usual, a few more warnings:
+  \begin{itemize}
+  \item No space or similar in front/after parenthesis.
+  \item Demands a consistent quote style.
+  \item Double spaces in input which will not be rendered as one.
+  \item Punctuation malplaced regarding to math mode.
+  \item Warns about \TeX\ primitives.
+  \item Space in front of footnotes.
+  \item Bogus {\tt\BS{}left} and {\tt\BS{}right} commands.
+  \end{itemize}
+
+\item 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\ldots
+\item 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 \Cmd{Resource.[ch]}.
+
+\item It's possible to specify separate output-formats depending on
+  whether you are sending the output to a file/pipe or to a
+  terminal.
+
+\item Column positions are finally correct; we now expand tabs
+  correctly.
+\item \chktex\ will now recursively search for {\tt\BS{}input}'ed
+  files, both in the document and on the commandline. See the 
+  \rsrc\ file for more info.
+\item 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.
+\item MS-DOS and OS/2 version of the program is now more flexible
+  and well-behaved, thanks to Gerd B\"ohm.
+\item You may now say \Cmd{-wall} to make all messages warnings, and
+  turn them on.
+\item Uses termcap on UNIX boxes; this should ensure that \Cmd{-v2}
+  (or more precisely: \Cmd{\%i} and \Cmd{\%I}) works regardless to
+  what terminal you are using.
+\end{itemize}
+
+\subsubsection{Resource file}
+
+New concepts introduced in the setup file:
+\begin{itemize}
+\item You may now specify both case-sensitive and case-insensitive
+  user patterns in the \rsrc\ file. In addition; it is now possible
+  to reset/clear lists.
+\item It is possible to specify how many arguments
+  (optional/required) \Cmd{WIPEARG} should wipe; it behaves also
+  somewhat more intelligent when the arguments stretch over multiple
+  lines.
+\item Global files will be read {\em in addition\/} to local ones. The
+  searching order has also been reversed in order to make this more
+  intelligent.
+\end{itemize}
+
+
+\subsubsection{Other}
+Various other stuff I've done to the product:
+
+\begin{itemize}
+\item The documentation has been polished and should now be easier
+  to use in practical situations.
+\item \Cmd{check} target in \Cmd{Makefile}, so you can check that
+  the installation succeeded. In fact, the \Cmd{Makefile} has been
+  enhanced in several other ways too, amongst other it is now GNU
+  conforming.
+\item \Cmd{deweb} is now documented; you may say \Cmd{man~deweb} to
+  get a few words of advice. The support script ({\tt chkweb}) does
+  now behave as the remaining package (accepting stdin input and flags).
+\item 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
+%latex
+  $\mbox{lacheck}\leftrightarrow\mbox{\chktex}$
+%!lacheck <-> \chktex\ %
+%endlatex
+  interface.
+
+  This means that you now can use \chktex\ just as easily as lacheck
+  when you're running AUC-\TeX.
+
+\item 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
+  \Cmd{dev/c/vbcc.lha}.
+\end{itemize}
+
+\subsection{Feature list}
+
+\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.
+      \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
+  the AUC-\TeX\ Emacs mode.
+\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 {\em 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{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-emacs-hack}:] Install a small file which
+      adds \chktex\ to the command menu of AUC-\TeX. This is to be
+      considered as a hack, and may break in future versions of
+      AUC-\TeX. It works fine under AUC-\TeX\ v2.9, though.
+
+      This option needs the path of your elisp directory as argument,
+      e.g. \Cmd{--enable-emacs-hack=/home/myself/elisp} or similar.
+
+      You'll also have to add the following line to your \Cmd{.emacs}
+      file:
+\begin{verbatim}
+(require 'chktex)
+\end{verbatim}
+      You can now access \chktex\ from the \Cmd{Command} menu in
+      AUC-\TeX. To cycle through the messages, type \verb#C-x `#.
+
+    \item[\Cmd{--enable-lacheck-replace}] This enables a quick
+      hack for making the AUC-\TeX\ Emacs mode use \chktex\ instead of
+      lacheck. This is done by installing a stub script which
+      ``overrides'' the original lacheck executable.
+
+      While more stable than the previous solution, this is also
+      significantly less elegant --- in computing terms, this is the
+      ``brute force'' approach.
+
+    \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.  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}
+{\bf Note:\/} You {\em must\/} install the new \rsrc\ file; \chktex\ will
+fail to function unless!
+
+    After   doing   this,   you   may  enhance  \chktex'  behaviour  by
+reading/editing the \rsrc\ file.
+

+\section{Usage}
+
+\subsubsection{Synopsis}
+
+A UNIX-compliant template format follows:
+
+\newcommand{\Group}[1]{\mbox{[#1]}}
+\begin{tabularx}\textwidth{lY}
+  \tt chktex & \tt \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[{\tt -h [--help]}] Gives you a command summary.
+  \item[{\tt -i [--license]}] Shows distribution information.
+  \item[{\tt -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 {\tt -g}.
+  \item[{\tt -r [--reset]}] This will reset all settings to their
+    defaults. This may be useful if you use the {\tt CMDLINE}
+    directive in your \rsrc\ file, and wish to do something
+    unusual.
+  \item[{\tt -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[{\tt -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 {\em all\/} warnings.
+  \begin{description}
+  \item[{\tt -w [--warnon]}] Makes the message number passed as
+    parameter a warning and turns it on.
+  \item[{\tt -e [--erroron]}] Makes the message number passed as
+    parameter an error and turns it on.
+  \item[{\tt -m [--msgon]}] Makes the message number passed as
+    parameter a message and turns it on. Messages are not counted.
+  \item[{\tt -n [--nowarn]}] Turns the warning/error number passed
+    as a parameter off.
+  \end{description}
+\item[Output control flags:] Determines the appearance and
+  destination of the error reports.
+  \begin{description}
+  \item[{\tt -q [--quiet]}] Shuts up about copyright information.
+  \item[{\tt -o [--output]}] Normally, all errors are piped to {\tt 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 {\tt 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[{\tt -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 {\em second\/} entry in the
+    \rsrc\ file), using {\tt -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 {\tt awk}, {\tt 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 {\tt 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[{\tt -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]{\tt \%#1 &}
+    \begin{tabularx}{\linewidth}{cX}
+      \bf Code & \bf Description \\
+      \Pf{b} String to print {\bf b\/}etween fields (from {\tt
+        -s} option). \\
+      \Pf{c} {\bf C\/}olumn position of error. \\
+      \Pf{d} Length of error ({\bf d\/}igit). \\
+      \Pf{f} Current {\bf f\/}ilename.\\
+      \Pf{i} Turn on {\bf i\/}nverse printing mode.\\
+      \Pf{I} Turn off {\bf i\/}nverse printing mode.\\
+      \Pf{k} {\bf k\/}ind of error (warning, error, message).\\
+      \Pf{l} {\bf l\/}ine number of error.\\
+      \Pf{m} Warning {\bf m\/}essage.\\
+      \Pf{n} Warning {\bf n\/}umber.\\
+      \Pf{u} An {\bf u\/}nderlining line (like the one which
+      appears when using \Cmd{-v1}).\\

+
+    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 {\em not\/} support field lengths (yet).

+
+    The {\tt -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[{\tt -V [--pipeverb]}] Which entry we'll use in the \rsrc\
+    file whenever {\tt stdout} isn't a terminal.
+
+    The default is to use the same mode as specified with the
+    {\tt -v} switch; using {\tt -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[{\tt -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[{\tt -s [--splitchar]}] String to use instead of the
+    colons when doing {\tt -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 {\tt 0}, the feature will
+  be disabled, if it is {\tt 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[{\tt -b [--backup]}] If you use the {\tt -o} switch, and the
+    named outputfile exists, it will be renamed to {\tt filename.bak}.
+  \item[{\tt -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[{\tt -H [--headererr]}] Show errors found in front of the
+    \verb@\begin{document}@ line. Some people keep {\em 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[{\tt -g [--globalrc]}] Read in the global resource file.  This
+    switch may be useful together with the {\tt -l} option.
+  \item[{\tt -t [--tictoc]}] Display a twirling baton, to show that
+    we're working. {\tt -v0} does an {\tt -t0}, too, as it assumes
+    that the user then uses the program non-interactively.  This is
+    now a no-op.
+  \item[{\tt -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 {\tt stdin}.  To abort {\tt stdin} input, press the
+following keycombinations:
+
+\smallskip
+\begin{tabular}{ll}
+  \bf Machine & \bf Key-combination \\
+  UNIX & $\fbox{\tt Ctrl} + \fbox{\tt D}$ \\
+  MS-DOS & $\fbox{\tt Ctrl} + \fbox{Z}$, followed by return.
+\end{tabular}
+\smallskip
+
+By default, we're using the 1994 version of 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 the file is
+self-documenting; you should be able to get the meaning of each
+keyword by simply reading the file. The method for {\em finding it},
+however, has grown rather complex. An outline is given below.
+
+If \chktex\ finds multiple files when searching, each and everyone
+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
+  \Cmd{/usr/local/share/chktexrc} or similar, 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{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}; 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.
+\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.
+
+Before submitting a bug report, please first see whether the problem can be
+solved by editing the \rsrc\ file appropiately.
+
+
+
+\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
+{\tt 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 {\tt 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}
+
+{\tt 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 {\tt
+  lacheck}, or spell-checkers like {\tt ispell}.
+
+When {\tt 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 {\tt cweave}, which output is truly difficult to figure
+anything out from).
+
+{\tt deweb} accepts a list of filenames on the argument line, and will send
+its output to {\tt 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 {\tt 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.
+
+{\tt deweb} should now understand all correct {\tt CWEB} opcodes.  If it
+complains about not understanding a correct opcode, please inform the
+author.
+
+\subsubsection{Bugs}
+
+{\tt deweb} will not even {\em 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{\large\tt\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.

+\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{Italic\\ItalCmd\\NonItalic}
+\begin{errdesc}{Italic correction (`\BS/') found in non-italic
+    buffer.}
+  If you try to use the \verb@\/@ command when \chktex\ believes that
+  the buffer is not outputted as italic, you'll get this warning.

+\end{errdesc}
+
+\Keyword{Italic\\ItalCmd\\NonItalic}
+\begin{errdesc}{No italic correction (`\BS/') found.}
+  You get this error if \chktex\ believes that you are switching from
+  italic to non-italic, and you've forgot to use the \verb@\/@ command
+  to insert that extra little spacing. If you use the \Cmd{em} option,
+  you may ignore this warning.
+

+\Keyword{IJAccent}
+\begin{errdesc}{Accent command `command' needs  use of `command'.}
+  If you're using accenting commands, `i' and `j' should lose their
+  dots before they get accented. This is accomplished by using the
+  \verb@\i@, \verb@\j@, \verb@\imath@ and \verb@\jmath@ command.
+
+  \begin{errexam}

+\end{errdesc}
+
+\Keyword{HyphDash\\NumDash\\WordDash}
+\begin{errdesc}{Wrong length of dash may have been used.}
+  This warning suggests that a wrong number of dashes may have been
+  used.  It does this by classifying the dash according to the the
+  character in front and after the dashes.
+
+  If they are of the same type, \chktex\ will determine which keyword
+  to use in the \rsrc\ file. If not, it will shut up and accept that
+  it doesn't know.
+
+  \begin{tabular}{ll}
+    \bf Character type & \bf Keyword in \rsrc\ file \\*
+    Space & \tt WordDash \\*
+    Number & \tt NumDash \\*
+    Alphabetic character & \tt HyphDash \\*
+  \end{tabular}
+
+  This is more or less correct, according to my references.  Hopefully
+  this check can be even more improved (suggestions?).
+
+  \begin{errexam}

+
+
+\fmted{`\%s' expected, found  `\%s'.}
+\begin{errdesc}{Solo `\%s' found.}
+  You get this warning whenever brackets or environments don't match.
+  \chktex\ expect to find matching brackets/environments in the
+  same order as their opposites were found, and no closing delimiters
+  which haven't been preceded by an opening one.
+
+  While bracket matching is not an explicit error, it is usually a
+  sign that something is wrong.
+
+\end{errdesc}
+
+\Keyword{CenterDots\\LowDots}
+\begin{errdesc}{You should use `\%s' to achieve  an ellipsis.}
+  Simply typing three \Cmd{.} in a row will not give a perfect spacing
+  withing the between the dots. The \verb@\ldots@ is much more
+  suitable for this.
+
+  In math mode, you should also distinguish between \verb@\cdots@ and
+  \verb@\ldots@; take a look at the example below.
+
+  \begin{errexam}

+\Keyword{Abbrev}
+\begin{errdesc}{Interword spacing (`\BS\ ') should perhaps be used.}

+\end{errdesc}
+
+\begin{errdesc}{Intersentence spacing (`\BS{}@') should perhaps be used.}
+
+  \LaTeX' detection of whether a period ends a sentence or not, is
+  only based upon the character in front of the period. If it's
+  uppercase, it assumes that it does not end a sentence. While this
+  may be correct in many cases, it may be incorrect in others.
+  \chktex\ thus outputs this warning in every such case.

+
+\begin{errdesc}{Could not find argument for  command.}
+
+  \chktex\ will in some cases need the argument of a function to
+  detect an error. As \chktex\ currently processes the \LaTeX\ file on
+  a line-by-line basis, it won't find the argument if the command
+  which needed it was on the previous line. On the other hand, this

+
+\begin{errdesc}{No match found for `\%s'.}
+
+  This warning is triggered if we find a single, {\em opening\/}

+
+\Keyword{MathEnvir}
+\begin{errdesc}{Mathmode still on at end of LaTeX  file.}

+                                %
+  For best looking documents, you should decide on how you
+  wish to put quotes relative to punctuation. \chktex\ recognizes two
+  styles; you may specify which you use in the \rsrc\ file. A
+  description on each style follows:
+  \begin{description}
+  \item[Traditional:] This style is the most visually pleasing. It
+    always puts the punctuation {\em in front of\/} the quotes, which
+    gives a continuous bottom line.
+
+    However, it may in certain cases be ambigious. Consider the
+    following example from a fictious \Cmd{vi(1)}
+    tutorial (quote taken from the Jargon file):
+    \begin{center}
+      \verb@Then delete a line from the file by typing ``dd.''@ \\*
+      Then delete a line from the file by typing ``dd.''
+    \end{center}
+    That would be very bad --- because the reader would be prone to
+    type the string d-d-dot, and it happens that in \Cmd{vi(1)} dot
+    repeats the last command accepted. The net result would be to
+    delete {\em two\/} lines! This problem is avoided using logical
+    style, described below.
+    \pagebreak[3]
+  \item[Logical:] This style uses quotes as balanced delimiters like
+    parentheses. While this is not the most visual pleasing, it is
+    can't be misunderstood. The above sentence would then become:
+    \nopagebreak
+    \begin{center}
+      \verb@Then delete a line from the file by typing ``dd''.@ \\*
+      Then delete a line from the file by typing ``dd''.

+\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 Do a final fix for maths mode. Currently, \chktex\ doesn't
+  recognize embedded math mode (i.e.\ constructions like
+  \verb@$$a+b\text{for $a \leq 0$}$$@).
+
+\item Support for regular expressions as user patterns. I'll do it at
+  once I get the GNU \Cmd{rx} package up and running (it doesn't
+  produce correct include files).
+
+\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 $\mbox{\LaTeX}\rightarrow \mbox{{\tt troff}}$
+  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{\tt html}, I'm willing to do the
+  same in order to produce {\tt 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, {\em 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 Arexx interfaces for other editors are also welcomed; these
+  should be rather fast to write.  They should to the following:
+  \begin{enumerate}
+  \item Get the filename of the active file.
+  \item If possible, save the file to disk if there has been any
+    changes.
+  \item Call the program \Cmd{ChkTeX.rexx} with the filename as the
+    only parameter.
+  \end{enumerate}
+
+\item If somebody out there actually possesses (and uses) GoldED, it
+  would be nice if they checked whether the ARexx script included
+  actually work.  If not, please send me a fixed copy; perhaps also
+  one which supports point 2 above, too. If it does work, then please
+  tell me so, so I can remove this item.
+
+  I don't have GoldEd in my possession; the script was just modelled
+  after Juergen Zeschky's, ({\tt <juergen@sokrates.nbg.de>})
+  $\mbox{PGP}\leftrightarrow\mbox{GoldED}$ interface.
+
+\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}
+
+This program uses the \Cmd{getopt()} routine, as supplied from GNU\@.
+The source included in this distribution has been modified slightly.
+To make the use of C2LOCAL easier, portions which were
+\verb@#ifdef@'ed out, have now been commented out.
+
+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 {\tt
+  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 {\tt 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{Stefan  Gerberding}{stefan@inferenzsysteme.informatik.th-darmstadt.de}
+  First one to report the Enforcer hit in v1.2 when using \chktex\ as

+  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.

+1.6.4 (2007-10-20)
+
+  - 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
+
+  - 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.

+/*
+ * Note: This file contains most defines you'll wish to change if you
+ * wish to adopt ChkTeX to a new system. It is, as you might notice,
+ * heavily documented. If you wish to get into the internals of ChkTeX,
+ * the interesting stuff is at the bottom of this file, and in the .c
+ * files. However, you should also take a look at the "config.h.in" file
+ * in this directory if you haven't got a shell able to run the "configure"
+ * script.
+ *
+ * This program relies heavily on that the system which
+ * automagically free()'s all malloc()'ed memory, works. The program
+ * itself does not call free() very much. This is because we're doing
+ * lots of tiny allocations, and a properly designed pooling system will
+ * hopefully do a quicker job than we'll be able to do. So there.
+ *
+ * To keep things simple, we trust that the fclose()'ing of fopen()'ed
+ * also happens automagically.
+ *
+ * Please use the getopt included, as we will modify optarg during
+ * command processing.
+ *
+ * You may wish to modify the SetupVars() (OpSys.c) to better suit your
+ * preferences. In any case, it should put the filename (and full path)
+ * of the `.chktexrc' file into the ConfigFile array. The array is sized
+ * BUFSIZ bytes.
+ *
+ * The program does also assume that __unix__ is defined if the source is
+ * compiled on a UNIX machine.

+;;; Commentary:
+;;
+;;  This tiny hack will add a "ChkTeX" item to the command menu of
+;;  AUC-TeX, thus making the use of ChkTeX much more comfortable from
+;;  within AUC-TeX (`LaTeX-mode').
+;;
+;;  INSTALLATION
+;;
+;;  1. Put this file somewhere in your loading path.
+;;  2. Add the line
+;;        (require 'chktex)
+;;     to your .emacs file
+;;
+;;  It is doubtful whether byte-compiling this file gains anything.
+;; 
+;;; Code:

+# 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 */

+.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.

+.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.

+The program will try to swallow the whole input file at once, instead of
+processing it on a line\-by\-line basis.

+\`configure' configures ChkTeX for TeX Live 1.6.4 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]

+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

+  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>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.
