-	from upstream.
-	(ChkTeX.pdf, CLEANFILES, stamp-tex, all-local,
-	DISTCLEANFILES, build-tex, EXTRA_DIST): so we don't need to build
-	it.  I guess.
-
-2012-03-01  Peter Breitenlohner  <peb@mppmu.mpg.de>
-
-	* getopt.h: With __need_getopt declare only getopt() but not
-	getopt_long() (with 'struct option').
-
-	* getopt.[ch]: Drop pre-ANSI C non-prototype declarations.
-
-2012-02-27  Ken Brown  <kbrow1i@gmail.com>

-# 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
-# configured tree to be moved without reconfiguration.

-    The GNU General Public License version 2 is included below for your reference.

-------------------------------------------------------------------------
-		    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>
-
-    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., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301,
-    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.
-
-  <signature of Ty Coon>, 1 April 1989
-  Ty Coon, President of Vice
-
-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.
-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.
-
-\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 \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 will be uploaded to CTAN\@; thus it can be
-found at any mirrors of those.
-
-\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.  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.
-  \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'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 it is
-self-documenting, you should be able to get the meaning of each
-keyword by simply reading the file. The method for \emph{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 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{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
-\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.

-\Keyword{Silent}
-\begin{errdesc}{Command terminated with space.}
-  You tried to terminate a command with a blank space.  Usually, this

-  \item[Traditional:] This style is the most visually pleasing. It
-    always puts the punctuation \emph{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 \emph{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''.@ \\*

-  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 $\mbox{\LaTeX}\rightarrow \mbox{\texttt{troff}}$
-  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 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, (\texttt{<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
-\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

-\begin{description}
-
-  \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 catched\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{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
-after 1.6 are essentially bug fixes.
-
-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.

- * Note: This file contains most defines you'll wish to change if you

- * 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

-;;; 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:
-;;
-
-(eval-after-load 'tex
-  '(progn
-     (add-to-list 'TeX-command-list
-                  '("ChkTeX" "chktex -v3 %s" TeX-run-compile nil t))))
-
-(provide 'chktex)

-#
-# 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 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 catched.
-#   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     - No. 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.
-#   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.

-# 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
-# right of of it.  We are only conclusive if they are the same.
-#
-# 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 an 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
-# NUMDASH { 2 }           # Between words
-# WORDDASH { 0 }          # We never use this

-.TH deweb 1 "June 8, 1996"
-.AT 3
-.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.
-.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

-      dnl Most compilers print some kind of a version string with some command
-      dnl line options (often "-V").  The version string should be checked
-      dnl before doing a test compilation run with compiler-specific flags.
-      dnl This is because some compilers (like the Cray compiler) only
-      dnl produce a warning message for unknown flags instead of returning
-      dnl an error, resulting in a false positive.  Also, compilers may do
-      dnl erratic things when invoked with flags meant for a different

-\`configure' configures ChkTeX for TeX Live 1.6.6 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.

-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>
-  PDFLATEX    pdfLaTeX command
-  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.

-
-   If an element of ARGV starts with '-', and is not exactly "-" or "--",
-   then it is an option element.  The characters of this element
-   (aside from the initial '-') are option characters.  If `getopt'
-   is called repeatedly, it returns successively each of the option characters
-   from each of the option elements.
-
-   If `getopt' finds another option character, it returns that character,
-   updating `optind' and `nextchar' so that the next call to `getopt' can
-   resume the scan with the following option character or ARGV-element.
-
-   If there are no more option characters, `getopt' returns -1.
-   Then `optind' is the index in ARGV of the first ARGV-element
-   that is not an option.  (The ARGV-elements have been permuted
-   so that those that are not options now come last.)
-
-   OPTSTRING is a string containing the legitimate option characters.
-   If an option character is seen that is not listed in OPTSTRING,
-   return '?' after printing an error message.  If you set `opterr' to
-   zero, the error message is suppressed but we still return '?'.
-
-   If a char in OPTSTRING is followed by a colon, that means it wants an arg,
-   so the following text in the same ARGV-element, or the text of the following
-   ARGV-element, is returned in `optarg'.  Two colons mean an option that
-   wants an optional arg; if there is text in the current ARGV-element,
-   it is returned in `optarg', otherwise `optarg' is set to zero.
-
-   If OPTSTRING starts with `-' or `+', it requests different methods of
-   handling the non-option ARGV-elements.
-   See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
-
-   Long-named options begin with `--' instead of `-'.
-   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 same ARGV-element, separated
-   from the option name by a `=', or else the in next ARGV-element.
-   When `getopt' finds a long-named option, it returns 0 if that option's
-   `flag' field is nonzero, the value of the option's `val' field
-   if the `flag' field is zero.
-
-   The elements of ARGV aren't really const, because we permute them.
-   But we pretend they're const in the prototype to be compatible
-   with other systems.
-
-   LONGOPTS is a vector of `struct option' terminated by an
-   element containing a name which is zero.
-
-   LONGIND returns the index in LONGOPT of the long-named option found.
-   It is only valid when a long-named option has been found by the most
-   recent call.
-
-   If LONG_ONLY is nonzero, '-' as well as '--' can introduce
