+Notes on the Free Translation Project
+*************************************
+
+   Free software is going international!  The Free Translation Project
+is a way to get maintainers of free software, translators, and users all
+together, so that will gradually become able to speak many languages.
+A few packages already provide translations for their messages.
+
+   If you found this `ABOUT-NLS' file inside a distribution, you may
+assume that the distributed package does use GNU `gettext' internally,
+itself available at your nearest GNU archive site.  But you do _not_
+need to install GNU `gettext' prior to configuring, installing or using
+this package with messages translated.
+
+   Installers will find here some useful hints.  These notes also
+explain how users should proceed for getting the programs to use the
+available translations.  They tell how people wanting to contribute and
+work at translations should contact the appropriate team.
+
+   When reporting bugs in the `intl/' directory or bugs which may be
+related to internationalization, you should tell about the version of
+`gettext' which is used.  The information can be found in the
+`intl/VERSION' file, in internationalized packages.
+
+Quick configuration advice
+==========================
+
+   If you want to exploit the full power of internationalization, you
+should configure it using
+
+     ./configure --with-included-gettext
+
+to force usage of internationalizing routines provided within this
+package, despite the existence of internationalizing capabilities in the
+operating system where this package is being installed.  So far, only
+the `gettext' implementation in the GNU C library version 2 provides as
+many features (such as locale alias, message inheritance, automatic
+charset conversion or plural form handling) as the implementation here.
+It is also not possible to offer this additional functionality on top
+of a `catgets' implementation.  Future versions of GNU `gettext' will
+very likely convey even more functionality.  So it might be a good idea
+to change to GNU `gettext' as soon as possible.
+
+   So you need _not_ provide this option if you are using GNU libc 2 or
+you have installed a recent copy of the GNU gettext package with the
+included `libintl'.
+
+INSTALL Matters
+===============
+
+   Some packages are "localizable" when properly installed; the
+programs they contain can be made to speak your own native language.
+Most such packages use GNU `gettext'.  Other packages have their own
+ways to internationalization, predating GNU `gettext'.
+
+   By default, this package will be installed to allow translation of
+messages.  It will automatically detect whether the system already
+provides the GNU `gettext' functions.  If not, the GNU `gettext' own
+library will be used.  This library is wholly contained within this
+package, usually in the `intl/' subdirectory, so prior installation of
+the GNU `gettext' package is _not_ required.  Installers may use
+special options at configuration time for changing the default
+behaviour.  The commands:
+
+     ./configure --with-included-gettext
+     ./configure --disable-nls
+
+will respectively bypass any pre-existing `gettext' to use the
+internationalizing routines provided within this package, or else,
+_totally_ disable translation of messages.
+
+   When you already have GNU `gettext' installed on your system and run
+configure without an option for your new package, `configure' will
+probably detect the previously built and installed `libintl.a' file and
+will decide to use this.  This might be not what is desirable.  You
+should use the more recent version of the GNU `gettext' library.  I.e.
+if the file `intl/VERSION' shows that the library which comes with this
+package is more recent, you should use
+
+     ./configure --with-included-gettext
+
+to prevent auto-detection.
+
+   The configuration process will not test for the `catgets' function
+and therefore it will not be used.  The reason is that even an
+emulation of `gettext' on top of `catgets' could not provide all the
+extensions of the GNU `gettext' library.
+
+   Internationalized packages have usually many `po/LL.po' files, where
+LL gives an ISO 639 two-letter code identifying the language.  Unless
+translations have been forbidden at `configure' time by using the
+`--disable-nls' switch, all available translations are installed
+together with the package.  However, the environment variable `LINGUAS'
+may be set, prior to configuration, to limit the installed set.
+`LINGUAS' should then contain a space separated list of two-letter
+codes, stating which languages are allowed.
+
+Using This Package
+==================
+
+   As a user, if your language has been installed for this package, you
+only have to set the `LANG' environment variable to the appropriate
+`LL_CC' combination.  Here `LL' is an ISO 639 two-letter language code,
+and `CC' is an ISO 3166 two-letter country code.  For example, let's
+suppose that you speak German and live in Germany.  At the shell
+prompt, merely execute `setenv LANG de_DE' (in `csh'),
+`export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash').
+This can be done from your `.login' or `.profile' file, once and for
+all.
+
+   You might think that the country code specification is redundant.
+But in fact, some languages have dialects in different countries.  For
+example, `de_AT' is used for Austria, and `pt_BR' for Brazil.  The
+country code serves to distinguish the dialects.
+
+   Not all programs have translations for all languages.  By default, an
+English message is shown in place of a nonexistent translation.  If you
+understand other languages, you can set up a priority list of languages.
+This is done through a different environment variable, called
+`LANGUAGE'.  GNU `gettext' gives preference to `LANGUAGE' over `LANG'
+for the purpose of message handling, but you still need to have `LANG'
+set to the primary language; this is required by other parts of the
+system libraries.  For example, some Swedish users who would rather
+read translations in German than English for when Swedish is not
+available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'.
+
+   In the `LANGUAGE' environment variable, but not in the `LANG'
+environment variable, `LL_CC' combinations can be abbreviated as `LL'
+to denote the language's main dialect.  For example, `de' is equivalent
+to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT'
+(Portuguese as spoken in Portugal) in this context.
+
+Translating Teams
+=================
+
+   For the Free Translation Project to be a success, we need interested
+people who like their own language and write it well, and who are also
+able to synergize with other translators speaking the same language.
+Each translation team has its own mailing list.  The up-to-date list of
+teams can be found at the Free Translation Project's homepage,
+`http://www.iro.umontreal.ca/contrib/po/HTML/', in the "National teams"
+area.
+
+   If you'd like to volunteer to _work_ at translating messages, you
+should become a member of the translating team for your own language.
+The subscribing address is _not_ the same as the list itself, it has
+`-request' appended.  For example, speakers of Swedish can send a
+message to `sv-request@li.org', having this message body:
+
+     subscribe
+
+   Keep in mind that team members are expected to participate
+_actively_ in translations, or at solving translational difficulties,
+rather than merely lurking around.  If your team does not exist yet and
+you want to start one, or if you are unsure about what to do or how to
+get started, please write to `translation@iro.umontreal.ca' to reach the
+coordinator for all translator teams.
+
+   The English team is special.  It works at improving and uniformizing
+the terminology in use.  Proven linguistic skill are praised more than
+programming skill, here.
+
+Available Packages
+==================
+
+   Languages are not equally supported in all packages.  The following
+matrix shows the current state of internationalization, as of September
+2001.  The matrix shows, in regard of each package, for which languages
+PO files have been submitted to translation coordination, with a
+translation percentage of at least 50%.

+used for implementing regional variants of languages, or language
+dialects.
+
+   For a PO file in the matrix above to be effective, the package to
+which it applies should also have been internationalized and
+distributed as such by its maintainer.  There might be an observable
+lag between the mere existence a PO file and its wide availability in a

+
+Using `gettext' in new packages
+===============================
+
+   If you are writing a freely available program and want to
+internationalize it you are welcome to use GNU `gettext' in your
+package.  Of course you have to respect the GNU Library General Public
+License which covers the use of the GNU `gettext' library.  This means
+in particular that even non-free programs can use `libintl' as a shared
+library, whereas only free software can use `libintl' as a static
+library or use modified versions of `libintl'.
+
+   Once the sources are changed appropriately and the setup can handle
+to use of `gettext' the only thing missing are the translations.  The
+Free Translation Project is also available for packages which are not
+developed inside the GNU project.  Therefore the information given above
+applies also for every other Free Software Project.  Contact
+`translation@iro.umontreal.ca' to make the `.pot' files available to
+the translation teams.

+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    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) <year>  <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., 59 Temple Place, Suite 330, Boston, MA  02111-1307  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) year  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.

+Basic Installation
+==================
+
+   These are generic installation instructions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+   The file `configure.in' is used to create `configure' by a program
+called `autoconf'.  You only need `configure.in' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes awhile.  While running, it prints some
+     messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  You can give `configure'
+initial values for variables by setting them in the environment.  Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile the package for one architecture at a time
+in the source code directory.  After you have installed the package for
+one architecture, use `make distclean' before reconfiguring for another
+architecture.
+
+Installation Names
+==================
+
+   By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc.  You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+   Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on.  Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+     CPU-COMPANY-SYSTEM
+
+See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the host type.
+
+   If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+Sharing Defaults
+================
+
+   If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Operation Controls
+==================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+     Use and save the results of the tests in FILE instead of
+     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
+     debugging `configure'.
+
+`--help'
+     Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--version'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+GPIV is a graphic user interface for analysing images obtained from a
+fluid flow that has been seeded with tracer particles by the so-called
+Particle Image Velocimety technique. It is meant to have a quick
+overview of the parameters of all piv processes, easely changing them,
+running the processes and visualizing their results in an interactive
+way. It uses LIBGPIV, which contains the main routines for data in-and
+output, processing etc. The software is written in ANSI-C under the
+LINUX operating system by using the GTK/GNOME libraries.
+
+GPIV is Free Software licenced under the GNU
+Public licence terms. See the COPYING file for the licence.
+
+*** homepage ***
+
+
+
+Compilation and installation 
+============================ 
+
+The General instructions of compilation and installlation can be found
+in INSTALL.  There are some additional configuration options for this
+program, as well. These are: 
+--enable-img-width=WIDTH
+--enable-img-height=HEIGHT 
+--enable-debug 
+--enable-demo
+An expalantion of these options is printed with ./configure --help.
+
+
+
+Features
+=========
+
+General
+========
+- Data storage in ASCII format or HDF version 5 format.
+- Loading of images with with file-open menu, "open" button or with "drag and 
+  drop" from the gnome filemanager "nautilus" into the buffer list.
+- Quick execution of all enabled process on all selected buffers.
+
+
+Display
+========
+- Visualization of interrogation area contours and highlighting them when 
+  pointing to it.
+- Displays pointer position and belonging estimated values.
+
+
+Image info
+===========
+- shows image name and dimensions
+- defining of spatial and time scales, position of image within the experiment.
+- Adding and updating header information.
+
+
+Image evaluation
+=================
+- Interrogation at the entire image or at a defined region within the image
+  frames resulting into a displacement field on a rectangular grid.
+- Interrogation at a single arbitrary point, along a vertical or horizontal 
+  line.
+- re-interrogation of a single area with, different parameters.
+- dragging a single interrogation area from the rectangular grid.
+- arbitrary interrogation area sizes.
+- global pre-shifting.
+- local pre-shifting or zero offsetting of the interrogation areas.
+- forward and central interrogation scheme
+- adaptive interrogation area sizes to obtain high resolution and dynamic range.
+- different interpolation schemes for sub-pixel estimation.
+- cross and auto correlation.
+- defining order of correlation peak to be used as estimator.
+- visualization of interrogation area's and correlation function
+
+
+Validation
+===========
+- manually enabling and disabling of PIV estimators 
+- checking on peaklocking effects
+- validation on outliers by snr value or median test
+
+
+Postprocessing
+===============
+- apply time and spatial scaling
+- calculate statistics and substraction of mean values from estimators
+- calculation of vorticity and strain.
+
+
+Currently the images can not be visualized, yet as the code is written
+with the GNOME 1.4 libraries. It is planned to include the images in
+the window that displays the data when the program will be ported to
+GNOME-2.  In that case the gnome-config allow to include pixmap images
+int the gnome canvas. Any help, especially on the visialization of
+images, on porting the program to GNOME-2 is welcome

+# This file can be copied and used freely without restrictions.  It can

+dnl Usage: AM_WITH_NLS([TOOLSYMBOL], [NEEDSYMBOL], [LIBDIR]).
+dnl If TOOLSYMBOL is specified and is 'use-libtool', then a libtool library
+dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
+dnl    depending on --{enable,disable}-{shared,static} and on the presence of
+dnl    AM-DISABLE-SHARED). Otherwise, a static library
+dnl    $(top_builddir)/intl/libintl.a will be created.
+dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
+dnl    implementations (in libc or libintl) without the ngettext() function
+dnl    will be ignored.
+dnl LIBDIR is used to find the intl libraries.  If empty,
+dnl    the value `$(top_builddir)/intl/' is used.
+dnl
+dnl The result of the configuration is one of three cases:
+dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
+dnl    and used.
+dnl    Catalog format: GNU --> install in $(datadir)
+dnl    Catalog extension: .mo after installation, .gmo in source tree
+dnl 2) GNU gettext has been found in the system's C library.
+dnl    Catalog format: GNU --> install in $(datadir)
+dnl    Catalog extension: .mo after installation, .gmo in source tree
+dnl 3) No internationalization, always use English msgid.
+dnl    Catalog format: none
+dnl    Catalog extension: none
+dnl The use of .gmo is historical (it was needed to avoid overwriting the
+dnl GNU format catalogs when building on a platform with an X/Open gettext),
+dnl but we keep it in order not to force irrelevant filename changes on the
+dnl maintainers.

+   Here is a matrix of mmap possibilities:
+	mmap private not fixed
+	mmap private fixed at somewhere currently unmapped
+	mmap private fixed at somewhere already mapped
+	mmap shared not fixed
+	mmap shared fixed at somewhere currently unmapped
+	mmap shared fixed at somewhere already mapped
+   For private mappings, we should verify that changes cannot be read()
+   back from the file, nor mmap's back from the file at a different
+   address.  (There have been systems where private was not correctly
+   implemented like the infamous i386 svr4.0, and systems where the
+   VM page cache was not coherent with the filesystem buffer cache
+   like early versions of FreeBSD and possibly contemporary NetBSD.)
+   For shared mappings, we should conversely verify that changes get
+   propogated back to all the places they're supposed to be.
+
+   Grep wants private fixed already mapped.
+   The main things grep needs to know about mmap are:
+   * does it exist and is it safe to write into the mmap'd area
+   * how to use it (BSD variants)  */

+.SH DESCRIPTION
+
+\fBbatch-gpiv\fP processes a \fBseries\fR of files in an identical
+way. If no parameters are defined at the command line, standard
+parameters will be used that are defined in the script. Actually, any
+program or script can be invoked by \fBbatch-gpiv\fP. In contrast to
+the UNIX* program batch, this script executes in foreground and does
+not schedule its priority."\fIprocess\fR" is string which contains the
+name of program to be executed, including eventually command line
+options and arguments. The filename to be processed, as defined with
+-fb c.s., will be appended to the string. If the program needs -f
+"filename", write -f at the end of the string.
+
+.SH Options 
+.TP
+\fB-dn [--dir_name] \fIdir base-name\fR
+The \fIdir base-name\fR represents the directory name without its last number. It is supposed that the last number in the directory name is a counter.
+.TP
+\fB-fd [--first_dir] \fIN\fR
+Defines the counter \fIN\fR of the first directory number at which the analyses starts.
+.TP
+\fB-ld [--last_dir] \fIN\fR
+Last directory number \fIN\fR at which the analyses ends.
+.TP
+\fB-fn [--file_name] \fIfile base-name\fR
+The \fIfilename\fR has to be given without its \fB.piv\fR
+extension. The \fIfile base-name\fR represents the file name without
+its last number, before the extension. It is supposed that the last
+number in the file name is a counter.
+.TP
+\fB-ff [--first_file] \fIN\fR
+Defines the counter \fIN\fR of first file number at which the analyses starts.
+.TP
+\fB-lf [--last_file] \fIN\fR
+Last file number \fIN\fR at which the analyses ends.
+.TP
+\fB-h [--help] \fP
+On-line help.
+.TP
+\fB-n [--none] \fP
+Suppresses real execution.
+.TP
+\fB-p [--print] \fP
+The program has been tested for PIV data. So far, it works fine.

+
+<P>
+<B>errvec</B> searches erroneous outliers in a PIV data stream and
+substitutes with new values, if possible, i.e. if (the majority) of its
+surroundings are non-erroneous.  Evaluation of erroneous vectors is
+done by looking up the Signal to Noise Ratio (SNR) value in the PIV
+data file or by calculating the median residu of the vector with its
+surroundings. A new displacement is obtained by the mean value of the
+surrounding values or by the x-and y displacements belonging to the
+median value or by the location of the next higher peak in the
+covariance function. The latter needs the use of <I>rr</I>.
+<P>
+The parameters and options to be used for <I>errvec</I> are
+subsequently searched <I>errvec.par</I> at local directory at
+<I>~/.gpivrc</I> or at<I>/etc/gpivrc</I>. Each parameter is 
+described by the program key (Err_V)
+and the parameter name, separated by a dot (.), followed by its
+value. Some of the parameters are optional. The parameters may be
+defined in arbitrary order. Blank lines and comment (starting with a
+pound sign (#) at the first column) may be included in the parameter
+files.  The parameters may be overruled by the command line options,
+as explained below.

+<B>flip</B> is a tool that belongs to the Particle Image Velocimetry
+(PIV) post-processing group. It interchanges (flips) the data in
+vertical (x) direction, horizontal (y) direction, rotates over 90 and
+180 degrees. As rotating over 180 degrees is similar to flipping over
+x as well as over y-direction, the program must be called twice or
+must be called once by <B>rot180</B>. Rotation over 90 degrees can only
+be applied by calling flip with <B>rot90</B>.
+<P>
+The <I>filename</I> has to be given without its .piv
+extension. The output will be written to
+<I>filename</I><B>.flip.piv</B>. The parameters will be written or added to
+<I>filename</I><B>.par</B>.
+<P>
+The parameters and options to be used for <B>flip</B> are subsequently
+searched in <I>filename.</I><B>par</B>, generated by <B>rr</B> and, eventually
+contains info about the input data, <I>flip.</I><B>par</B> at local directory
+or at <I>~/.Pivrc</I>. Each parameter is described by the program key
+(Flip) and the parameter name, separated by a dot (.), followed by its
+value. The parameters may be defined in arbitrary order. Blank lines
+and comment (starting with a pound sign (#) at the first column) may
+be included in the parameter files.  The parameters may be overruled

+
+<A NAME="1"><H2>2.1 Starting up</H2></A>
+
+By invoking "gpiv" the GPIV console will be launched that consists a
+menu bar, a toolbar, process toggle-buttons, a tabulator and a data
+buffer list (<a href="#fig1">Figure 2.1</A>). At the bottom of the
+console you can find an application bar that displays information of the
+highlighted item as well as a progress bar that displays the progress
+of the running process. 
+<br>
+GPIV reads its default program parameters from ~/.gnome/gpiv following
+the GNOME conventions. These parameters can be defined by command line
+keys for the current session (invoke "gpiv --help" for information
+about the options) or in the settings->preferences from the console
+menu's. The variables that are used for interrogation, validation and
+post-processing are read from ~/.gpivrc or from the system-wide
+available gpivrc (mostly /etc/gpivrc under Unix/Linux) respectively.

+<A NAME="fig1" id="gpiv-fig2">Figure 2.1 GPIV console with image inormation 
+tabulator</A>
+<P>
+
+<A NAME="2"><H2>2.2 Menu and toolbar</H2></A>
+
+The menu bar consists general tasks for GPIV, like file-handling,
+preferences and help menus. Underlined characters represent the ALT
+short-hand key for launching the menus.
+<P>
+The "File" menu contains the menus "open", "save", "save as" for
+reading and storing data and "exit" for closing the application.
+<P>
+The settings menu contains the menus "gpiv buttons" and "tabulator" to
+(un)display these parts of the console and "preferences" for defining
+all GPIV settings. Closing the "preferences" menu
+with "OK" stores the settings for future sessions. "Apply" only
+affects the current session. "Cancel" undisplays the preferences menu
+without action.
+<P>
+The "help" menu contains "show tooltips" for obtaining additional
+help. Tooltips are small windows that pop up when an item is
+highlighted and contain more extended information about the item than
+can be displayed at the application bar. The "manual" menu shows this
+document. "about" gives short info about the application.
+<P>
+
+The toolbar is a quick way for opening/saving images and data,
+executing/stopping processes that are enabled by the process toggle
+buttons below of the toolbar and for exiting the program.
+
+
+
+<A NAME="3"><H2>2.3 Process toggle-buttons</H2></A>
+
+The process toggle-buttons may be switched on in order to define a
+chain of processes that include interrogation, validation and
+post-processing. The settings of the processes are defined in the
+tabulator below. The chain is invoked by the "Execute" button on the
+toolbar and, eventually, interrupted by the "Stop" button.
+
+
+<A NAME="4"><H2>2.4 Data buffer list and display window</H2></A> 
+
+The data buffer list contains a number and the base name of the image
+(without its extesion). A single buffer may be selected by pointing to
+it and left mouse clicking. Several buffers may be selected by
+clicking the first and last buffer while holding the "Shift" key. An
+execution of a process will than be performed on every selected
+buffer. 
+<P>
+
+For each buffer a display window is launched that contains the
+image (not visible in this version of GPIV), squared frames that
+represent the interrogation areas of the first and the second image
+(in different colors), vectors representing PIV estimators and derived
+scalars that are obtained from the PIV estimators by post
+processing. The interrogation areas are highlighted when the pointer
+is moving over them. At the bottom of the diplay window an application
+bar shows the position of the pointer, centre point of the highlighted
+inetrrogation area and, eventually, values of the PIV estimators and
+its derived quantities. The same information is diplayed in the
+application bar of the GPIV console as well. When clicking the right
+mouse button when it points at the display window, a menu pops for
+in-and outzooming the window, (un)displaying features and choosing
+vector lenght.
+
+
+
+<A NAME="5"><H2>2.5 Tabulator</H2></A>
+
+The tabulator contains image header data, image evaluation, validation
+and post-processing parameter settings and buttons to invoke the
+individual processes. 
+
+<A NAME="5.1"><H3>2.5.1 Image info</H3></A>
+
+The most left tabulator 'Image Info' (<a href="#fig1">Figure 2.1</A>)
+shows information of the image. The image dimensions are defined in
+gpiv_gtk.h and can not be changed during execution of GPIV. In case
+different dimensions will have to be researched, its definition has to
+be changed and gpiv will have to be recompiled. Time scaling, spatial
+scaling, the positions of row #0 and column #0 (related to a typical
+location in the experiment) are the same as in the Post processing
+tabulator.  These parameters are used for scaling and positioning the
+PIV data. The image header items "Project", "Creation date", "Place",
+and "Comment" are optional.
+
+
+<A NAME="5.2"><H3>2.5.2 Evaluation</H3></A>
+
+The 'Evaluation' tab (<a href="#fig2">Figure 2.2</A>) shows all the
+settings for interrogation a image (pair).

+- The upper-left corner of the image represents pixel # (0,0). The
+starting point (first col/row) and the end-point (last col/row) of the
+image to be interrogated may be defined in the entry-fields as well as
+a global pre-shift in horizontal (pre-shift col) and vertical
+(pre-shift row). The first column and row, as defined in the entrys will
+always be included in the interrogations. The last column/row of the image
+to be analysed depends on Interrogation Area sizes and shifts, but
+will never exceed the last column/row as defined in the
+entry-fields. 
+<P>
+
+- The size of the interrogation area and the shift of adjacent area's, 
+expressed in image pixels, are defined by entrys (for arbitrary
+dimensions) or or by radio-buttons (for power of 2 dimensions)
+'Int. Size 1', 'Int. Size 2' and 'Shift'. As the size of the second
+interrogation area has to be equal or larger than the first one, some
+of the settings in the entries and of the radio buttons may be disabled
+for manipulations.
+<P>
+
+- "Mouse select":
+<P>
+
+"None" disables mouse activitiy within the viewer window.
+<P>
+
+Enabling "Area", entering a viewer window, pressing the right mouse
+button and moving the mouse creates a rectanglar frame that defines the area
+to be interrogated. This is an alternative for using the entries "first/last
+col/row". The entry values will be updated automatically.
+<P>
+
+Enabling "Single int.", entering a viewer window and clicking the right mouse button
+invokes a new interrogation at the highlighted interrogation area. Already existing 
+estimators will be conserved.
+<P>
+
+Enabling "Single point", entering a viewer window and clicking the right mouse
+ button invokes a new interrogation at an arbitrary point.
+Already existing estimators will be thrown away!
+<P>
+
+Enabling "Drag int." and entering a viewer window causes to displace
+(drag) the highlighted interrogation area. An adjacent interrogation
+area is highlighted and dragged in case the pointer is closer to its
+centre point. Clicking the right mouse button invokes an interrogation
+at the centre point of the (displaced) interrogation area. Already
+existing estimators will be conserved.
+<P>
+
+With "Vert. line" a vertical line in the image may be defined at which
+a single column of interogation areas are to be drawn. Interrogation
+of the line has to be performed by clicking the "piv" button at the
+bottom of the "Evaluation" tabulator or by enabling the "piv" process
+button and pressing the "Execute" button on the toolbar.
+<P>
+With "Hor. line" a horizontal line in the image may be defined at which a 
+single row of interogation areas are to be drawn.Interrogation
+of the line has to be performed by clicking the "piv" button at the
+bottom of the "Evaluation" tabulator or by enabling the "piv" process
+button and pressing the "Execute" button on the toolbar.
+<P>
+
+- "Interpolation scheme": interpolation scheme for estimating the correlation
+peak at sub-pixel level.
+<P>
+
+- Peak #: normally the highest correlation peak is used (or the
+second highest in case of auto-correlation, which is done automatically
+if auto-correlation has been enabled). An erroneous velocity
+vector, though, might be caused by a high noise peak in the correlation
+function that overwhelmes the 'true' particle displacemnt peak. Searching
+the second or third highest peak may result in a correct estimation.
+<P>
+
+- Interrogation with: a linear weight kernel in order to correct for
+biasing effects that is generated by the estimation of the correlation
+function. In case zero offset is enabled, i.e. a second interrogation
+is performed with a pre-shift of the local estimator, the new
+correlation peak is found between -1 and +1 pixels. In that case
+kernel weighting will over-correct and, therefore, is disabled. If
+zero-offsetting is enabled, the 'classic' forward interrogation scheme
+is choosen or a central differential scheme may be used.
+Interrogation following the central differential scheme is done by
+displacing the interrogation area of the first image with half the
+magnitude of the pre-shift value in negative direction and displacing
+the interrogation area of the second image in positive direction (of
+identic magnitude).
+<P>
+
+- "Correlation"; in case recordings have been
+performed on separate image frames ("Auto") or on one single frame ("Cross").
+<P>
+
+- "Interrogation areas and correlation": displays interrogation areas and 
+correlation function, together with the estimated displacement vector
+by enabling the "Display" button. Though, this uption
+is unstable, yet.
+<P>
+
+- At the bottom of the "Evaluation" tabulator the "piv" button may be
+invoked to interrogation the image. The function of this button is
+similar to the command line program <A href="rr.html"> rr </A> of
+gpivtools.

+
+- "Disable data": to put PIV data into  (in)active state for further processing.
+At inactive state the vector color will be displayed red. 
+<P>
+activate "Enable/Disable point" to put in active/inactive state by pointing 
+and clicking a single PIV estimator.
+<P>
+activate "Enable/Disable area" to put in active/inactive state a rectangular 
+area containing PIV data. The starting corner of the area (upper-left) to be 
+disables is defined by pressing the right mouse button. The opposite corner
+is defined by moving the mouse with pressed button and realxing the button at
+the location of the opposite corner. A rectangular frame is drawn during the 
+operation.
+<P>
+
+-"peak lock" displays a histogram of sub-pixel estimators of the PIV
+dataset. This button is similar to the command line program <A
+href="peaklck.html"> peaklck </A> of gpivtools.
+<P>
+
+"residu statistics" displays the (log) inverse histogram of median residus. The
+critical residu value for accepting/rejecting outliers is determined by the 
+slope of the straight line. The critical value is calculated and displayed in 
+the "Threshold" entry. This button is similar to the command line program <A
+href="errvec.html"> errvec </A> of gpivtools.
+<P>
+
+Activating the "validate on velocity gradient" button puts all vectors
+into red color if they exceed the critical value of the velocity
+gradient over an interrogation area. The critical value is defined in
+libgpiv/include/gpiv/valid.h: GRADIENT_THRESHOLD and is set to 2
+pixels, i.e. identic to the optimum particle image diameter. This
+quantity is choosen in order to prevent a too wide, or even a
+splitting up of the highest correlation peak.
+<P>
+
+"Outliers" defines the parameters for testing and substituting on
+erroneous vectors.  The type of residus may be choosen between "Snr"
+or "Median". The "Data yield" has to be filled in manually and should
+be obtained from the mean number of particles within an interrogation
+area. The critical threshold may be filled in manually or may be
+obtained by invoking "residu statistics" button. Outliers are
+substituted by the local mean value of surrounding vectors, by the
+median value of surrounding vectors or by interrogating the area with
+a next highes correlation peak. Finally, the validation on outliers is
+performed by pressing the "validate on outliers" button. This button
+is similar to the command line program <A href="errvec.html"> errvec
+</A> of gpivtools, too.

+The "Post processing" tab (<a href="#fig4">Figure 2.4</A>) contains
+tools to apply modifications on PIV estimators and to calculate
+derived quantities from the PIV estimators.
+<P>
+
+spatial scaling is calculated by measuring the number of pixels per
+mm. For the moment, this measuring has to be performed with different
+image visualization tools. The time scale represents the time between
+two succesive image recordings (mostly the separation time between two
+laser flashes). The location of the image within an experiment is
+defined by the position of column and row #0, related to a marker
+point in the experiment. Enabling the "Apply" button will display the
+scaled data in the application bars of the buffer window and of the
+console, including their positions in the experiment. This will not
+affect the original data set itself, yet. The conversion of the data
+is performed during storage execution. So, disabling the "Apply"
+button will display the original (unscaled) estimators and their
+position in the image, expressed in pixels. This button is similar to
+the command line program <A href="scale.html"> scale </A> of the
+gpivtools distribution.
+<P>
+
+Vorticity, shear and normal strain may be derived from the PIV
+estimators with different numerical schemes; Central differential
+scheme, Least squares, Richardson and the Circulation method (only for
+the calculation of vorticity). This button is similar to the command
+line program <A href="vorstra.html"> vorstra </A> of the gpivtools
+distribution.

+<H2>DESCRIPTION</H2>
+
+<P>
+<I>hilo</I> is a low-band pass
+filter for removing (non-homogeneos) background illumination and
+maximizing the contrast of images. For this purpose it searches for
+each pixel the highest and lowest pixel value within a window. By moving the window over the image, a maximum and a minimum envelope is
+found. The envelopes are smoothed by linear interpolation. For each
+pixel in the image the minimum envelope is substracted from the pixel
+value and the maximum envelope is stretched to the maximum pixel
+value, defined by the number of bits a pixel is represented (255
+for 8 bits image)
+<P>
+The parameters and options to be used for <I>hilo</I> are subsequently
+searched in <I>hilo.par</I> at local directory, at
+<I>~/.gpivrc</I> or at <I>/etc/gpivrc</I>. Except for the number of input data, each parameter is
+described by the program key (F_HL) and the parameter name, separated
+by a dot (.), followed by its value. The parameters may be defined in
+arbitrary order. Blank lines and comment (starting with a pound sign
+(#) at the first column) may be included in the parameter files.  The
+parameters may be overruled by the command line options, as explained

+
+GPIV (<a href="#fig1">Figure 1.1</A>) is a program that performs
+Particle Image Velocimetry (PIV) interrogations on a (pair of)
+images. A short explanation about PIV and related techniques is given
+in <a href="piv_intro.html">Chapter 3</A>. It also includes validation
+of the estimators and post-processing on the PIV data that result into
+derived (scalar) flow quantities. It is meant to have a quick overview
+of the parameters of all piv processes, to change them easely, to run
+the processes and visualizing their results in an interactive way. It
+visualizes interrogation area's, piv estimators, outliers, velocity
+gradients over the interrogation area's and post processing results in
+a single window frame. The graphical user interface of GPIV has been
+written with the GTK/GNOME libraries. Currently, the images itself can
+not be visualized, yet.
+<P>
+
+Actually, GPIV is one of the end-user programs that makes extensively
+use of libgpiv. Libgpiv includes the main algorithms for
+interrogation, validation, post-processing, memory (de)allocation,
+in-and output handling, etc. Other end-user programs may be found in
+the gpivtools distribution. Gpivtools contains command line programs
+that may be invoked from a shell or from scripts. Some example
+scripts, written in PERL can be found in the gpivtools distrib, as
+well. All codes have been written in ANSI-C and have been developed on
+a LINUX box.

+
+<P>
+Peak-locking effects in Particle Image Velocimetry (PIV) result into
+estimations of the particle displacments that are mainly at an integer
+number of pixels, instead of at sub-pixel displacements. This effect
+may due to stretching of the (round) pixel images, due to a too low
+resolution of the pixel-image or may due to signal interferences of the
+data from camera to frame grabber.  <B>Peaklck</B> calculates the
+particle displacement distribution at sub-pixel level in between 0.0
+an 1.0 (0 included, 1 excluded). If peaklocking occurs, a non-uniform
+distribution of the estimated particle displacements at sub-pixel

+<H1>3 Quantitative Flow Visualization techniques </H1></A>
+
+<a name="1"><H2>3.1 Introduction </H2></A> 
+
+For quantitative flow visualization techniques, a flow is visualized
+by seeding the fluid with small particles that allow to follow the
+instantaneous changes of the flow. The region in the flow to be
+researched is illuminated, mostly by a sheet of light. This
+light-sheet is generated by an expanding laser beam by means of a
+cylindrical lens or due to the projection of the beam on a rotating
+hexagonal mirror. The instantaneous flow is recorded at least twice by
+very short light flashes with a separation time (Dt) in between that
+is known. The flashes have to be sufficiently short in order
+image the particle shape. Too long illumination times will result into
+streaks of the particle images that will not allow to determine the
+exact particle location in the fluid. Several illuminations result in
+trace patterns of each particle on the image plane. Analyzing these
+particle traces result in local particle displacements. As the
+separation time between the recordings is known, the analyses directly
+result in velocities. Mainly two different techniques are known:
+Particle Tracking Velocimetry (PTV) and Particle Image Velocimetry
+(PIV). The difference is in the density of the seeding. In literature
+the particle density is often represented by two dimensionless
+parameters; the image particle density <var>NI</var> and source
+density <var>NS</var>. The source density represents whether the
+particle images are overlapping (<var>NS</var> &gt 1) or can be
+recogized individually (<var>NS</var> &lt 1). <var>NI</var> represents
+the ratio of the length of the particles tracks between successive
+illuminations and the distances between individual particles.
+<P>
+
+
+
+<a name="2"><H2>3.2 Particle Tracking Velocimetry </H2></A>
+
+In case of PTV a sparse seeding is used (<var>NS</var> &lt 1 and
+<var>NI</var> &lt 1). Therefore, each particle trace can be analyzed
+individually. As the particles are present at random locations in the
+fluid, the velocity estimators are found at random locations in the
+flow, too. Velocities that have to be obtained in-between the points
+of observations will have to be interpolated. PTV is a relatively easy way
+for obtaining quantitative information of the flow. Interpolation,
+though, is only allowed if the smallest scales of the flow are much
+smaller than the distances between the points of observation. Mainly
+laminar flows may satisfy this demand.
+<P>
+
+
+
+<a name="3"><H2>3.3 Particle Image Velocimetry </H2></A> 
+
+In case of turbulent flows, a whole spectrum of eddies occur with
+maximum dimensions related to the flow domain and minimum dimensions
+in the order of the Kolmogorov length scale (a few millimeters for
+laboratorium experiments). In order to observe these large ranges of
+eddy sizes, a high particle density is needed (<var>NI</var> &gt
+1). This means that it is impossible to track the individual
+particles. Therefore, the <em>mean</em> displacement of particles in a small
+region of the image(s) (the interrogation area) has to be
+calculated. <br>
+
+<spacer size=25> Actually, not the particle displacements are
+analyzed, but the image <em>transparency</em> as function of the relative
+translation within the interrogation area's. For computerized images
+the image density is represented by the pixel values. By locating the
+maximum transparancy the mean displacement of the particles in the
+interrogation area has been found. The transparancy can be obtained by
+shifting the two interrogation areas and subsequently plotting a
+two-dimensional histogram of the transparancy. This shifting may be
+performed physically, in case of analog images (i.e. photographic slides)
+or by means of a numeric algorithm, in case of digital PIV (DPIV). An
+other way to obtain the 2-dimensional transparancy function is by
+(auto) correlating the interrogation area's of the image. For analog
+images the correlation function may be obtained by optical Fourier
+Transformation techniques. The interrogation area, then, is
+determined by the diameter of the laser beam that interrogates the
+image. In case of DPIV, the calculation time of Fourier Transforming
+an interrogation area increases linearly with its dimension
+(NxN). Therefore, a more efficient method is mostly used by means of
+Fast Fourier Transformation (FFT) techniques. With FFT the
+calculation effort is related to Nlog(N), which means that it is
+advantagous for interrogation areas large than 16x16 points. Typical
+dimensions of an interrogation area for Digital PIV are 16x16 to
+128x128 pixels.<br>
+
+<spacer size=25> In order to obtain a reliable estimator of the particle image
+displacement, about 10 to 15 particles in an interrogation area have
+to be present. <br>
+
+<spacer size=25> As the particle image density is very high, the
+entire image may be interrogated at arbitrary locations. Mostly, the
+interrogation process is performed on a rectangular grid of
+interrogation areas that are adjacent or partly
+overlapping. Therefore, in contrast to PTV, PIV results in a two
+dimensional velocity field on a rectangular grid.
+<P>
+
+
+
+<a name="4"><H2>3.4 Laser Speckle Velocimetry </H2></A>
+
+In case particles are overlapping (<var>Ns</var> &gt 1) no individual
+particles can be recognized anymore. By using a coherent light source,
+a pattern of speckles is generated due to interferences of the
+coherent light. The speckel pattern, then, is imaged and
+recordered. Evaluations of interrogation areas from subsequent
+recordings, in a identical way as is done for PIV, will result into
+the displacements of the speckle patterns. As extremely high particle
+densities are needed, penetration of the light sheet is difficult and
+care should be taken that particles will not affect the flow
+itself. Laser Speckle Velocimetry is mostly used for determining of
+velocities of solid surfaces in transport mechanisms (photocopy
+machines, for example).
+<P>
+
+
+<a name="5"> <H2>3.5 Other techniques</H2></A>
+PIV has been evolved from photographic PIV in its beginning , some 15
+to 20 years ago, that interrogates the slides by optical Fourier
+Transformation to digital PIV, that uses CCD cameras and computer
+techniques to carry out the interrogation. Nowadays, even three
+dimensional PIV within the light sheet is done by observing the flow
+with two or more cameras that are looking under different angels to
+the area of researchlight. <br> <spacer size=25> Holographic PIV does not have
+the restriction of the thickness of the light sheet. It allows to
+research a region in the flow that is defined by the coherence length
+of the laser source. Their analyses result in three-dimensional
+velocities on a three-dimensional grid. <br> <spacer size=25> An other
+technique that has been reported is 'Global Doppler
+Velocimetry'. It uses the doppler shift of the reflected light from
+the particles. The doppler shift is then recorded on an image. Time
+averaging is needed in order to obtain sufficiently signal So, this
+technique results in <em>time averaged</em> velocities at <em>every pixel</em>
+of the image, instead of every 16x16 or 128x128 pixels in case of PIV.

+
+<P>
+<B>rr</B> co<I>rr</I>elates an image or image pair that is obtained from
+a fluid flow by the so-called Digital Particle Image Velocimetry
+(DPIV) technique. The image(s) are subdevided in interrogation areas
+at which the mean particle displacements are estimated. This is done
+by correlating the interrogation areas resulting into a
+two-dimensional covariance function. The covariance function is
+obtained by Fast Fourier Transformation (FFT) techniques. The location
+of the covariance peak then represent the mean particle image
+displacement within the interrogation area. Estimation of the
+covariance peak at sub-pixel level is possible by different
+interpolation schemes.  The program allows cross-correlation of
+single-exposed images on different frames or auto-correlation of
+multi-exposed single-frame images. Analyses with different sizes of
+interrogation areas between the first and second frame allows large
+dynamic ranges of the particle displacements. Zero off-setting of the
+interrogation areas by an iterative evaluation process allows high
+accuracy of the particle image displacements.
+<P>
+For cross-correlation of single-exposed multi-frame images, <B>rr</B>
+has to be fed by the (raw or ASCII) data of the images, the second
+image concatenated after the first one. If not stdin and stdout is
+used (with <B>-f </B><I>filename</I>), the images have to be called
+<I>filename</I><B>.1.r</B> and <I>filename</I><B>.2.r</B> (raw image format) for
+cross-correlation and <I>filename</I><B>.r</B> for auto-correlation. The
+number of rows and columns are read from the ASCII file
+<I>filename</I><B>.h</B>. Output will then be written to
+<I>filename</I><B>.piv</B>, containing the estimators of the particle
+displacements, <I>filename</I><B>.par</B> with the used parameters for
+<I>rr</I>, <I>filename</I><B>.cov</B> with covariance data (optional) and
+<I>filename</I><B>.1.int</B>, <I>filename</I><B>.2.int</B> with actual
+interrogation regions (optional). Particle displacements from a
+previous analysis (eventually obtained without sub-pixel estimation)
+may be used as local pre-shifts for further analysis. In that case the
+input file <I>filename</I><B>.piv</B> will be renamed to
+<I>filename</I><B>.old.piv</B>.
+<P>
+The parameters and options to be used for rr are subsequently searched
+in <B>rr.par</B> at local directory, at
+<I>~/.gpivrc</I> or at <I>/etc/gpivrc</I>. Each parameter is described by the program key (Rr)
+and the parameter name, separated by a dot (.), followed by its
+value. Some of the parameters are optional. The parameters may be
+defined in arbitrary order. Blank lines and comment (starting with a
+pound sign (#) at the first column) may be included in the parameter
+files.  Parameters may be overruled by the command line options,
+as explained below. If <B>-f</B> has been used, the used parameters are
+written to <I>filename</I><B>.par</B>. By renaming this file to
+<B>rr-2.2.par</B>, it may directly be re-used for identic analyses of
+other images.

+<H2>Options </H2>
+
+<DL COMPACT>
+<DT><B>-ad_int</B> <DD>
+Adaptive interrogation size; The size of the second interrogation
+region may be choosen larger than the first one in order to obtain
+high dynamic ranges. Though, this may result into low spatial
+resolutions of the PIV estimators. Only if <B>-z</B> has been set,
+<B>-ad_int</B> will adapt the size of the 2nd interrogation region to
+the first one after the first iteration step, resulting into higher
+spatial resolutions. See also <B>-col_start</B>, <B>-row_start</B> and
+<B>-int_size_2</B><I>N</I>.
+<DT><B>--ad_int</B> <DD>
+Supresses adaptive interrogation size.  
+<DT><B>-autokey</B><DD>
+Sets automatically parameters that depend on others: zero_off is set to 1 if 
+ad_int = 1 , weight is set to 0 if zero_off = 1 and weight is set to 1 
+if zero_off = 0.
+<DT><B>-cmpr </B><I>N</I> <DD>
+Compresses the image with factor <I>N</I> by taking the mean value of
+the <I>N</I>x<I>N</I> pixel values. <I>N</I> has to be a power of
+2. <B>-cmpr</B> can only be used in combination with -fit equal to
+0. This option will speed up the image analyses by a factor
+<I>N</I>**2. The output, may be read as local pre-shift
+values in a next image evaluation, similar to <B>-z</B>.
+<DT><B>--cmpr</B> <DD>
+Suppresses image compression.
+<DT><B>-c </B><I>N</I> <DD>
+Specify the number of columns with <I>N</I> that
+contains the image.  
+<DT><B>-cf </B><I>N</I> <DD>
+Specify the first column <I>N</I> in the image to interrogate. If <B>-ad_int</B> has been used, the first column has to be equal or larger than 
+(<B>int_size_2</B> - <B>int_size_1</B>)/2.
+<DT><B>-cl </B><I>N</I><DD>
+Specify the last column <I>N</I> in the image to interrogate.  
+<DT><B>-cp </B><I>N</I><DD>
+Pre-shift of <I>N</I> columns. This can be used if
+there is a common mean flow in x-direction in the area of
+observation. Relative small interrogation areas (allowing a high spatial
+resolution) may be used in that case with conservation of a high
+probability in finding the correct displacement peaks.
+<DT><B>-f </B><I>filename</I> <DD>

+Interpolation model for peak maximum estimation at sub-pixel

+<DT><B>-isi1 </B><I>N</I> <DD>
+Size of first interrogation area <I>N</I>, expressed in pixels. Must be

+<DT><B>-isi2 </B><I>N</I> <DD>
+Size of second interrogation area <I>N</I>. Must be a power of two and
+must be equal or larger than <B>isi1</B>. Larger sizes of the 2nd
+interrogation area allows particle displacements larger than 1/4th of
+the first interrogation size (which is generally recommended in order
+to keep in-plane error at minimum), i.e. an increase of dynamical
+range. Though, the Signal to Noise Ratio (SNR) may decrease in that
+case, resulting in a lower probability in finding the correct
+displacement peak. It is adviced to keep the ratio of the second and
+first interrogation size below 4. In combination with <B>ad_int</B> the
+SNR and spatial resolution (i.e. independancy of neighbouring
+interrogation regions) may be increased significantly during a next
+iteration sweep.
+<DT><B>-ish </B><I>N</I><DD>
+Shift of adjacent interrogation areas <I>N</I>, expressed in pixels.
+<DT><B>-k</B><DD>
+Uses kernel weighting. This is applied in the calculation of the

+<DT><B>--k</B><DD>
+Suppresses kernel weighting.
+<DT><B>-o</B> <DD>
+Reads an old output file from a previous evaluation with <B>rr</B>

+<DT><B>-peak </B><I>N</I><DD>
+Find the <I>N</I>-th maximum of the covariance peak. In case of

+denotes the zero-shift of the particle displacements.
+<DT><B>-p_cov</B><DD>
+Print the covariance function.

+Print the interrogation region(s).

+displacement vectors. A new estimation of the particle displacement
+with -peak may give a correct result. Mind to use <B>-p_piv</B>
+if <B>-f</B> is used; else the original data file will be overwritten

+<H2>DESCRIPTION</H2>
+
+<P>
+<I>vorstra</I> calculates the differential
+quantities like vorticity, shear strain and normal strain from PIV
+data. You can choose from several differential schemes: central
+differentiation, least squares, Richardson
+extrapolation and circulation method. Circulation method allows only
+to calculate vorticity, but no strain. The output can be generated
+as ASCII data containing four columns or as GNUPlot Data format that
+allows to view/print the data as contour plots.
+<P>
+The parameters and options to be used for <I>vorstra</I> are
+subsequently searched in <I>vorstra.par</I> at local directory, at
+<I>~/.gpivrc</I> or at <I>/etc/gpivrc</I>. Except for the number of
+input data, each parameter is described by the program key (Vos) and
+the parameter name, separated by a dot (.), followed by its
+value. Some of the parameters are optional. The parameters may be
+defined in arbitrary order. Blank lines and comment (starting with a
+pound sign (#) at the first column) may be included in the parameter
+files.  The parameters may be overruled by the command line options,
+as explained below.

+/* This file redirects the gettext functions (without prefix or suffix) to
+   those defined in the included GNU gettext library (with "__" suffix).
+   It is compiled into libintl when the included GNU gettext library is
+   configured --with-included-gettext.
+
+   This redirection works also in the case that the system C library or
+   the system libintl library contain gettext/textdomain/... functions.
+   If it didn't, we would need to add preprocessor level redirections to
+   libgnuintl.h of the following form:
+
+#    define gettext gettext__
+#    define dgettext dgettext__
+#    define dcgettext dcgettext__
+#    define ngettext ngettext__
+#    define dngettext dngettext__
+#    define dcngettext dcngettext__
+#    define textdomain textdomain__
+#    define bindtextdomain bindtextdomain__
+#    define bind_textdomain_codeset bind_textdomain_codeset__
+
+   How does this redirection work? There are two cases.
+   A. When libintl.a is linked into an executable, it works because
+      functions defined in the executable always override functions in
+      the shared libraries.
+   B. When libintl.so is used, it works because
+      1. those systems defining gettext/textdomain/... in the C library
+         (namely, Solaris 2.4 and newer, and GNU libc 2.0 and newer) are
+         ELF systems and define these symbols as weak, thus explicitly
+         letting other shared libraries override it.
+      2. those systems defining gettext/textdomain/... in a standalone
+         libintl.so library (namely, Solaris 2.3 and newer) have this
+         shared library in /usr/lib, and the linker will search /usr/lib
+         *after* the directory where the GNU gettext library is installed.
+
+   A third case, namely when libintl.a is linked into a shared library
+   whose name is not libintl.so, is not supported. In this case, on
+   Solaris, when -lintl precedes the linker option for the shared library
+   containing GNU gettext, the system's gettext would indeed override
+   the GNU gettext. Anyone doing this kind of stuff must be clever enough
+   to 1. compile libintl.a with -fPIC, 2. remove -lintl from his linker
+   command line.  */

+dnl Curses detection: Munged from Midnight Commander's configure.in
+dnl
+dnl What it does:
+dnl =============
+dnl
+dnl - Determine which version of curses is installed on your system
+dnl   and set the -I/-L/-l compiler entries and add a few preprocessor
+dnl   symbols 
+dnl - Do an AC_SUBST on the CURSES_INCLUDEDIR and CURSES_LIBS so that
+dnl   @CURSES_INCLUDEDIR@ and @CURSES_LIBS@ will be available in
+dnl   Makefile.in's
+dnl - Modify the following configure variables (these are the only
+dnl   curses.m4 variables you can access from within configure.in)
+dnl   CURSES_INCLUDEDIR - contains -I's and possibly -DRENAMED_CURSES if
+dnl                       an ncurses.h that's been renamed to curses.h
+dnl                       is found.
+dnl   CURSES_LIBS       - sets -L and -l's appropriately
+dnl   CFLAGS            - if --with-sco, add -D_SVID3 
+dnl   has_curses        - exports result of tests to rest of configure
+dnl
+dnl Usage:
+dnl ======
+dnl 1) Add lines indicated below to acconfig.h
+dnl 2) call AC_CHECK_CURSES after AC_PROG_CC in your configure.in
+dnl 3) Instead of #include <curses.h> you should use the following to
+dnl    properly locate ncurses or curses header file
+dnl
+dnl    #if defined(USE_NCURSES) && !defined(RENAMED_NCURSES)
+dnl    #include <ncurses.h>
+dnl    #else
+dnl    #include <curses.h>
+dnl    #endif
+dnl
+dnl 4) Make sure to add @CURSES_INCLUDEDIR@ to your preprocessor flags
+dnl 5) Make sure to add @CURSES_LIBS@ to your linker flags or LIBS
+dnl
+dnl Notes with automake:
+dnl - call AM_CONDITIONAL(HAS_CURSES, test "$has_curses" = true) from
+dnl   configure.in
+dnl - your Makefile.am can look something like this
+dnl   -----------------------------------------------
+dnl   INCLUDES= blah blah blah $(CURSES_INCLUDEDIR) 
+dnl   if HAS_CURSES
+dnl   CURSES_TARGETS=name_of_curses_prog
