+		    GNU GENERAL PUBLIC LICENSE
+		       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) 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., 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) 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.

+Dec    27, 2004 : Jeff Snyder
+	* Fix for bug 95640 (nothing displayed when kompare is embedded in Ark
+	  fixed by forcing the delivery of childEvents to komparesplitter at 
+	  the end of its constructor
+
+Dec    20, 2004 : Jeff Snyder
+	* Things that have happened since 3.3:
+	  (this list is not complete)
+	* Look & feel changed
+
+Dec    20, 2004 : Jeff Snyder
+	* Things that were changed sometime between Nov 25, 2003 and KDE 3.3:
+	  (this list is not complete)
+	* KompareConnectWidget became draggable, by replacing KompareViewFrame
+	  with KompareSplitter.
+
+Dec    20, 2004 : Jeff Snyder
+	* This changelog seems to have been neglected for over a year now. I'll
+	  try to retroactively fix this as and when I remember things that have
+	  been fixed - but it'll probably never be complete and accurate for the
+	  Dec 2003 - Nov 2004 period. I'll be making entries concering what i'm
+	  doing with kompare from now onwards.
+
+Nov    25, 2003 : Otto Bruggeman
+	* Fix nasty looping to the end of the file when hitting previous difference on the first difference in the first file
+
+Nov    25, 2003 : Laurent Montel
+	* Fix memleak, QStringList is implicitly shared so no need for a reference, it is already a pointer to data thing
+
+Nov    23, 2003 : Otto Bruggeman
+	* Fixed version string (bug 68872)
+	* Fix for 68871 (added slotNextDifference to slotApplyDifference())
+	* Fix for a crash: dont call blendOriginalIntoModelList with Kompare::ShowingDiff
+
+Nov    22, 2003 : Otto Bruggeman
+	* Fix to make the bugs.kde.org dialog pop up instead of sending a mail to John when pressing 
+	  Help->Report bug... Also added my homepage since it has always been kompare's home imo.
+
+Nov    22, 2003 : Otto Bruggeman
+	* Rework the blendFile method so it actually works and as a bonus is a bit faster
+	  This introduces a new form of show entire file when comparing, one that works
+	  And because of it, it saves files properly now because the entire file is now available even if 
+	  you have a single line change in a million line file with only 2 context lines in the diff.
+
+Nov    22, 2003 : Otto Bruggeman
+	* Remove the Show entire file option. It only causes problems at the moment
+	  Fixes bug 68729
+
+Nov    22, 2003 : Otto Bruggeman
+	* Commenting out a lot of debug output, it has served it's purpose well in levenshteintable.cpp
+
+Nov    21, 2003 : Otto Bruggeman
+	* Also expand tabs to spaces in strings without or after Commands (in the INLINE_DIFFERENCES 
+	  code path and yes commands is a shitty name for them but i cant think of something decent)
+
+Nov    21, 2003 : Otto Bruggeman
+	* Real Fix (tm) for activating the Swap source with destination action
+
+Nov    21, 2003 : Otto Bruggeman
+	* Fix empty line drawing in the INLINE_DIFFERENCES code path
+
+Nov    20, 2003 : Otto Bruggeman
+	* When swapping source with destination also change the windows caption and the statusbar text
+	* Make sure that when swapping and when there are changes, all changes that were made can be 
+	  saved, discarded or cancel the whole swap (strings are recycled from the queryClose method)
+	* Give a better parent to the KIO::NetAccess::download in komparemodellist.cpp
+	* Added some FIXME's for after the branching to make the urls appear in bold in the error message
+	* Make queryClose not use the isModified from the part but from the modellist
+
+Nov    20, 2003 : Otto Bruggeman
+	* Fix for activating the Swap Source with Destination action.
+
+Nov    19, 2003 : Otto Bruggeman
+	* Fixed bug 68570, it needed temp vars otherwise it was overwriting source with destination and then 
+	  overwriting that destination with source which was just changed into destination
+
+Nov    17, 2003 : Otto Bruggeman
+	* Fix for empty -x and -X arguments.
+	* Fix bugs 58858 and 58531 by using Kompare::Custom instead of Kompare::Default
+	* Fix last selected url in the kurlcomboboxes
+	* Fix for inline differences when there is only 1 char left that still needs to be drawn
+	* Remove support for the -a Treat all files as text diff option. This caused all sorts of weird crashes
+	  when parsing the diff output now with the custom options.
+	* Move the per preference page code in the diffprefs constructor into seperate methods per page
+
+Nov    14, 2003 : Otto Bruggeman
+	* Fix to make Kompare listen to the kdisplayFontChanged signal and set the font properly and redraw with the new font.
+	  Found by David Faure.
+
+Nov    09, 2003 : Otto Bruggeman
+	* Implemented inline differences (deactivated until KDE3.2 has been branched)
+	* added support for the -x and -X options to diff (deactivated until KDE3.2 has been branched)
+	* Various other code cleanups/reindenting
+
+Nov    09, 2003 : Otto Bruggeman
+	* Code cleanups
+
+Nov    02, 2003 : Otto Bruggeman
+	* Fixed some more scrolling problems
+	  lastItem->scrollId(), add lastItem->maxHeight() and substract the minScrollId()
+	  That is the maxScrollId i need in the QScrollBar, took me long enough...
+
+Oct    05, 2003 : Otto Bruggeman
+	* Fixed the scrolling problems, a stupid regression i introduced, i cant simplify mathematic expressions apparently
+	* Added an implementation for double clicking a difference in the view, but it is not properly connected yet
+	  void contentsMouseDoubleClickEvent ( QMouseEvent* );
+	* Fixed embedding in Konqueror by implementing openURL()
+	* Removed m_maxScrollId, it is not necessary and only costs time, QScrollView::contentsHeight() does the same
+	* Fixed some more warnings about unused variables
+	* Fixed the initial drawing of the vertical and horizontal scrollbar
+
+Oct    04, 2003 : Otto Bruggeman
+	* Added a call to m_modelList->openDirAndDiff to openDirAndDiff

+Sep    24, 2003 : Otto Bruggeman
+	* Fixes opening diffs, comparing files after moving all that code around
+
+Sep    23, 2003 : Otto Bruggeman
+	* Moved a lot of url downloading to the kompare part and moved the opening and reading of the downloads to komparemodellist

+	* Fixed the initialization of the difault var
+
+Aug    27, 2003 : Otto Bruggeman
+	* After shitloads of trouble here finally some fixes for the stupid desktop
+	  file stuff
+	* Fixes for when there are not enough args for a certain commandline option.
+
+Aug    22, 2003 : Otto Bruggeman
+	* Fixed converting tabs to spaces in the view, i totally screwed up
+	* View settings now get applied to the view after pressing ok.
+	  (Maybe i should make them apply on APlly instead of OK)
+
+Aug    13, 2003 : Otto Bruggeman
+	* Komkommertijd :) InitialPreference=10 for kompare.desktop as
+	  requested
+
+Aug    10, 2003 : Otto Bruggeman

+	  (kompare_shell.cpp 1.33 -> 1.34). This is about roaming user fixes.
+	  Thanks Helge !
+
+Jul    19, 2003 : Otto Bruggeman
+	* Backported Ingo Klocker's changes from head to make_it_cool
+	  (kompare_shell.cpp 1.34 -> 1.35). This is about being able to
+	  configure the shortcuts from kompare_part as well. Thanks Ingo !
+
+Jun    29, 2003 : Otto Bruggeman
+        * Fixed bug 58144 by adding a check for comparing dirs, in that case
+          destinationURL is a directory and not a file name so we need to
+          recreate the filename. This involved changing some code to use a
+          different enum value, so i hope i did it the right way, session
+          management may be broken now when the session was stored with 3.1.2
+          and restarted with 3.1.3. But that is unfortunately unfixable with a
+          kconf_update script.
+
+Jun    29, 2003 : Otto Bruggeman
+	* Removed a lot of commented code since it is no longer used and will
+	  never be used again.
+	* Added 2 methods to the interface: openDiff3(KURL) and 
+	  openDiff3(QStringList)
+	* Fixed context diff parsing as indicated in bugreport 57774
+	  (the example works now, hope there are no regressions)
+	* Removed all references to MiscSettings and MiscPrefs.
+	  These classes will disappear RSN.
+	* Fixed the history saving of the urls in the kompare dialog
+	* Parser is no longer a static class but one that needs to be
+	  instanciated
+	* Added ViewSettings to KompareProcess, maybe it is better to merge the
+	  diff and view settings into one class.
+
+May     3, 2003 : Otto Bruggeman
+	* Implemented support for -I in the regular diff options (the one in
+	  the kompare options dialog)
+	* Fixed the braindamage i created in main.cpp so that kompare no
+	  longer stalls because of a missing mainwindow
+	* Made the kcomparedialog more generic and renamed it to
+	  kompareurldialog so i can reuse it for blending too
+	* Removed some braindamage in the kompare/Makefile.am
+	* Some compile fixes because of changes to the CXXFLAGS
+	  (QRegExp::match cant be used anymore, and some other old style stuff)
+	* Added an action to the menu for blending
+	* moved Open file (or in this case Open Diff) to the top of the file
+	  menu
+	* Fixed the accel conflict in the file menu between open diff and
+	  compare files
+
+Apr    30, 2003 : Otto Bruggeman
+	* Implemented blending of a diff file with the original file
+	* Renamed General* View* (more appropriate)
+	* Renamed m_models into m_modelList since it is more appropriate in komparepart
+	* Small fixes to the view, but they break more than they fix :(
+	* Added commandline options for comparing, opening a diff file and
+	  blending
+
+Apr    20, 2003 : Otto Bruggeman
+	* Fixed bug 54264 with a statusbar that gets too wide when long
+	  filenames are used
+	* Fixed the missing endline problem in the parser (bug 56552)
+	* Fixed all copyright years (probably too many but hey i'll change
+	  those files some time this year so it will be valid :P)
+	* Added support for using a different diff program (Bug 55573)
+	* Added support for using a different tabsize in the viewer (Bug 38776)
+	* The interface is now final i guess so this fixes bug 42849, not
+	  every method is implemented but i'll get to them eventually.
+
+Apr    19, 2003 : Otto Bruggeman
+	* Fixed bug 56322 where openURL did not clear the models when called
+	  again with a new diff
+
+Aug     9, 2002 : Otto Bruggeman
+	* Fixed the whatsthis text for the compare button in the compare dialog
+	* Fixed the history of the comboboxes in the compare dialog
+	* Put the komparemodellist and all needed classes in a Diff2 namespace
+	* Implemented a better parser design (see parser.cpp/h)
+	* Removed the need to directly link to the komparepart for the shellapp
+	* Removed the need to link directly to the komparepart for the navigationpart
+	* Added support for perforce diffs in the new Parser classes
+	* Added a push design for the modified status instead of a pull design
+	* Added an interface to the Komparepart so people can use that to
+	  reuse the komparepart
+
+Jul    15, 2002 : Otto Bruggeman
+	* Fixed normal diff a bit more, filenames dont work yet
+	* Removed some code duplication
+	* Fixed diff output parsing with Common subdirectories in it
+	* Fixed Copyright years in the about box (thanks Carsten Niehaus)
+	* Removed the KShellProcess and replaced it with a KProcess
+
+Feb    18, 2002 : Otto Bruggeman
+	* Fixed scrolling with a wheel mouse in the kompare(list)view and
+	  connectwidget and added a config option for the number of lines
+	  that is scrolled per wheelscroll.
+	* Fixed the history somehow in the compare dialog.
+	* Implemented the separate directory/file widget.
+	* Implemented reading from stdin by using - as file on the commandline.
+	* Partly implemented a better way for ed and rcs parsing, i'll
+	  improve this before KDE 3.0 is released
+
+Jan    10, 2002 : Otto Bruggeman
+	Comparing directories works now :) You can select them from the begin
+	dialog, and select a directory and then press ok. It will enter the
+	directory but dont select a file so it keeps the directory.
+	Known bug here is that directories need a trailing slash :(
+
+Oct    07, 2001 : Otto Bruggeman
+	Fix crash when part is not found, basically dont use kapp->quit()
+	but use exit(int). Would be interested to know why it crashes though,
+	the bt gave nothing meaningful here. I should have compiled kompare with
+	debug code.
+
+Sep    17/18, 2001 : Otto Bruggeman
+	Fixed some stuff dont know what anymore (writing this on oct 7)
+	Probably some more fixes for the klibloader.
+
+Sep    17, 2001 : Otto Bruggeman
+	Moved to kdesdk and renamed to kompare with preservation of history.
+	Changed almost every occurence of kdiff to kompare (not in this file).
+
+Sep    08, 2001 : Otto Bruggeman
+	Removed the qt3back dir, changed everything over to qt3,
+	qlist->qptrlist, qlistconstiterator->qptrlistconstiterator
+
+Jul    29, 2001 : John Firebaugh
+	Add some tests.
+	Add the qregexp3 backport.
+	Use qregexp3 for diff parsing -- soooo much cleaner.
+	All the diff options work.
+
+Jul    28, 2001 : John Firebaugh
+	Directories can be selected in the compare dialog
+	New base clase KDiff, holds some common stuff
+	Use an enum for format in preferences
+	Implement a save options dialog, displayed at "Save .diff"
+	The diff can be run in any directory, the paths to source
+	and destination will be automatically determined from this.
+	Save all.
+
+Jul    25, 2001 : John Firebaugh
+	Prompt to save changes on close
+	Show [modified] caption
+	Clean up internal save mechanism
+
+Jul    14, 2001 : John Firebaugh
+	New menu item "Swap source and destination".
+	Make empty selection work.
+
+Jul    13, 2001 : John Firebaugh
+	Text view now works in compare mode.
+	Fix clicking difference to select it.
+	Don't scroll to difference when clicking to select it.
+	Give the diff view a nice frame.
+
+Jul    12, 2001 : Otto Bruggeman
+	Stats work now, maybe they need more info but i dont know what yet.
+	Will think some more about it.
+
+Jul    12, 2001 : John Firebaugh
+	When comparing files, you can apply or unapply changes and save
+	the result.
+	New menu item "Show Text View" (loads the diff in embedded text viewer).
+	Better status notification.
+	Set the window caption when comparing.
+
+Jun    27, 2001 : John Firebaugh
+	Ported main view to QListView
+	Remove obsolete files
+	Clicking a difference in the main view selects it
+	Better scrolling
+
+Jun    24, 2001 : John Firebaugh
+	Coverted to dock window and added navigation tree in a dock.
+	Multiple file diffs are now supported. Each file will show up
+	as an item in the tree, with differences as children.
+
+Jun    22, 2001 : Otto Bruggeman
+	Tried implementing rcs and ed but they dont work atm, same for show
+	diffstats, will fix that asap.
+
+May    22, 2001 : John Firebaugh
+	Reworking of most of the view code. Looks pretty.
+
+May    18, 2001 : Otto Bruggeman
+	Context seems to work, implemented saving... might have some problems
+	left (saving that is)
+
+May    15, 2001 : John Firebaugh
+	Make the settings work for all windows. Probably some more changes :)
+
+May    14, 2001 : Otto Bruggeman
+	context diff does not work atm, there is some problem with the separa-
+	tion of old and new. Maybe the old and new needs to be reintegrated.
+	I fixed some functions and now diffmodel does no longer need static
+	functions. All loading is done from the kdiffpart and that is where
+	save should go as well. Removed determineDiffFormat because it is not
+	needed anymore.
+
+May    13, 2001 : Otto Bruggeman
+	contextdiff is better implemented it finds all stuff in the diff atm
+	but it does not work.
+
+May    04, 2001 : Otto Bruggeman
+	cleaned up the code by moving the part to a subdir
+	halfassed implementation of contextdiff, will update later today
+
+Apr    10, 2001 : John Firebaugh
+	use new model/view architecture (not completely implemented yet)
+	NOTE: it will (should) compile, but you won't see any differences... a
+	work in progress
+
+Apr    05, 2001 : Otto Bruggeman
+	Implemented the ability to move from chuck to chunk in the htmlview
+	Cleaned up the preferences, squashed a few bugs
+
+Apr    04, 2001 : Otto Bruggeman
+	Normal format works as well
+
+Apr    04, 2001 : Otto Bruggeman
+	Finally implemented the preferences menu... i still lack some nice
+	icons for it but that will be solved in the near future...
+
+Mar    25, 2001 : Otto Bruggeman
+	Moved the application icons to the pics dir
+
+Mar    20, 2001 : Otto Bruggeman
+	Fixed a stupid bug that caused the last line in the rightview not
+	to be colored.
+	Implemented slots for using the KHistoryCombo in the views to select
+	files with.
+	Still a nasty bug with regard to the initial directory in the
+	KFileDialog, needs to be fixed asap but i dont know the cause.
+	Still an error in the historylist and completionlist items. They are
+	not shown correctly.

+Kompare General design:
+
+Kompare is split up into 4 parts:
+- A shell around the parts
+- A library with the modellist and the parser
+- The navigation tree which uses the library
+- The view part that also uses the library
+
+The diffmodel is comparable to a document and the view part is comparable
+to the view and the komparemodellist is comparable to a documentmanager. 
+The navtree can be viewed as a document view manager.
+The model is fully separated from the view and all communication goes 
+through signals and slots. The view gets a model that contains all differences
+for the compared files A and B. The view gets this model from the modellist,
+the central entity in the part.
+
+There is an interface to the komparepart that can be used in other programs, 
+simply link to the libkompareinterface.la and call its methods after you have 
+instanciated a komparepart. There is also a "hidden" signal and slot interface 
+that can be connected to from the shell app to get some information, and an 
+interface for communication between the navigation part and the komparepart.
+
+There is no need to use the interface for the communication between the 
+navigation and kompare parts in the shell app.
+
+Kompare has some debug areas:
+
+8100        kompare
+8101        kompare (libs)
+8102        kompare (shell)
+8103        kompare (part)
+8104        kompare (list view)

+Kompare 2.0
+
+Kompare is a program to view the differences between files. Features include:
+
+  * comparison of files or directories via a graphical interface
+  * bezier-based connection widget lets you see both source and destination
+    as they really appear
+  * graphical viewing of patch files in normal, context, unified and
+    diff formats
+  * interactive application of differences
+  * full network transparency
+  * ability to view plain-text diff output in embedded viewer
+  * easy navigation of multiple-file diffs with dockable navigation tree
+  * graphical interface to commonly used diff command line options
+  * switch source and destination with one command
+  * diff statistics

+!!! Must do before a merge back into HEAD !!!
+* Write a kconfupdate script to convert the kconfigfile
+  * the diff options now have their own group
+  * the view options now have their own group
+  * the Recent Files group has been renamed to Recent Compare Files
+
+Very important:
+* Make sure unified and context actually work again !
+* Implement the rest of the interface (compare3 etc.)
+* Make sure the rest works too ! Still some problems parsing some files
+* Other various things that need to be fixed asap (before 3.2 is released)
+
+In descending order of importance:
+* Add a kompare manual/document
+* add support for handediting conflicts
+* session management (should almost work)
+* implement normal, ed and rcs format (normal got busted)
+* merge text view GUI
+* clicking in the connect widget should select a difference (tricky!)
+* add support for incremental patch saving (i'll explain if anyone wants to know)
+* Add support for diff3 (that is comparing 3 files at once)
+
+Special requests:
+Puetzk:
+* Editing the TO pane
+Falk:
+* Allow only part of a change to be applied to the other file
+Harlekin:
+* Add search functionality, either in source, dest or both at the same time
+HarryF:
+* emit clicked() signal when on a diff with line number
+aseigo:
+* merge from dest to source instead of only from source to dest
+(Workaround: swap source with destination and then apply the differences)

+! 						Vim KPart
+! 
+! 
+! 									by Philippe Fremy <[email protected]>
+! 
+! 
+! Okay, I made it : a Vim KPart!
+! 
+! This means that you can have Vim embedded inside Konqueror, and everywhere a
+! text ReadWrite or ReadOnly KPart is requested. Actually, there is almost no
+! place right now where this is the case in KDE. KMail uses its own editor,
+! KDEvelop uses its own editor, Kate uses some more powerful Kate component.
+! 
+! But this only the beginning. Enabling a part in those programs shouldn't be
+! much hassle and you can probably help me do it. My hope is really to get
+! KDevelop use Vim.
+! 
+! 
+! ======= OBSOLETE ===========
+! Requirements:
+! -------------
+! To make this KPart work, you need a graphicial Vim version 6 with the client-server stuff feature activated and with the vim60-vimpart-patch.diff applied. The patch is in this dir. I hope to get it into the main Vim tree.  KVim has already the patch but is slightly less stable that the original GVim.  A big advantage of KVim is that you get the native KDE dialogs when vim asks a question.
+! 
+! 
+! ======= OBSOLETE ===========
+! Installation:
+! -------------
+! To make your vimpart work, you'll have to go into the vimpart directory and run "testVim your_patched_vim". If the test does work, a file goodVim will be created. You will be able to install and use the component. Else, the test will report why it fails (features missing in vim).
+! 
+! 
+! 
+! ======= OBSOLETE ===========
+! Testing:
+! --------
+! If you want to see your component without installing it, you can do the
+! following:
+! 
+! 1. configure, build. Then go into the Vimpart subdirectory.
+! 
+! 2. Include the current Vimpart directory in your KDEDIRS:
+! export KDEDIRS=`pwd`:$KDEDIR
+! 
+! 3. Symlink .libs to lib
+! ln -s .libs lib
+! 
+! 4. Create pseudo share/services dir:
+! mkdir share; mkdir share/services;
+! 
+! 5. Symlink to Vimpart.desktop:
+! ln -s Vimpart.desktop share/services/Vimpart.desktop
+! 
+! 6. Create a pseudo share/config dir
+! mkdir share/config;
+! 
+! 7. Symlink to vimwidgetrc
+! ln -s vimwidgetrc share/config/vimwidgetrc
+! 
+! 8. Update the desktop mimetype database:
+! kbuildsycoca
+! 
+! To test it, run VimPartShell. Or run konqueror from this dir and click on a
+! text file.
+! 
+! 
+! ======= OBSOLETE ===========
+! Remarks:
+! --------
+! The initial preference of the Vim KPart is 10. Kate uses 8, so if you install the part, it will override Kate for all the mimetypes. You can always change that by manually editing the initial preference in the desktop file or by simply selecting which editor you prefer for which mimetype in the control center.
+! 
+! If you find some mimetype not handled by the Vim KPart although they should be, send me a patch!
+! 
+! 
+! 
+! How it works:
+! -------------
+! At the beginning, we started to write KVim, a port of GVim to KDE to make
+! it possible to embed Vim inside KDE. But with the latest version of Vim, it
+! turns out that it is not necessary to have a native Vim.
+! 
+! 
+! I use QXembed, a widget which can embed any X application if it knows its X Window Id, using some X feature.  The patch I provide will make vim displays its window id on stdout when the window is mapped. GVim 6.0 then provides a way to send commands to a Vim window from another process. If you look at the VimWidget source, you will see that 70% of the code is there to handle the communication process. The rest uses the communication channel to send the vim commands needed by kpart and ktexteditor.
+! 
+! As far as I can tell, the part is race-condition free. If you issue many sendNormalCmd and many evalExpr, they are guaranted to be executed sequentially. This has caused me enough problems when it wasn't the case!
+! 
+! 
+! Qt, KDE2 and KDE3:
+! ------------------
+! The VimWidget itself depends very litle on KDE. It is quite easy to port remove the KDE specific stuff, to use it in a Qt only program. In fact, at the beginning, it was only Qt-based.
+! 
+! 
+! 
+! ======= OBSOLETE ===========
+! Features & TODO:
+! ----------------
+! I think most basic features required by an editor widget or part are supported. There are some possible improvement but I would like more feedback to know what really needs to be done. So don't hesitate to write me about your feelings using this.
+! 
+! My TODO list is:
+! - restore the editing mode after sendCmd
+! - implement KTextEditor interface
+! - add some useful actions to the part (like search, ...)
+! 
+! 
+! 
+! Feedback:
+! ---------
+! For the Vim KPart : [email protected]
+! For KVim: [email protected], [email protected], [email protected]
+! 
+! 
+!

+! Yes, that's really a Vim Komponent :)
+! Yes, you can have Vim inside KDE apps, you guessed it :)
+  
++ So, it's designed for KDE 3.x (if someone wants to port it to KDE 2 that

++ It can be used in different apps :

++ 	- Konqueror (as a file viewer)
++ 	- KWrite
++ 	- KMail (coming in KDE 3.2)
++ 	- Kompare, KBabel ........ ;)
++ 
++ CONFIGURATION
++ =============
++ once you compiled and installed it as any other app, 
++ start your KDE Control Center, go to the file manager section
++ and open the Vim Component configuration module.
++ Here, you have to select a Vim executable which may be found on 
++ your computer (generally /usr/bin/vim) will do it fine for most
++ linux distributions. All you need is that it's a GUI-enabled Vim 6.0 or
++ better.
++ Push the test button, if that's okay then that's should be enough to start
++ using it :)
++ 
++ FUNCTIONMENT
++ ============
++ Philippe Fremy ([email protected]) wrote the initial version of this kpart.
++ The concept is to start a normal GUI Vim (like gvim), then "embeds" the Vim
++ window into a KDE Widget.
++ It used to be based on the ClientServer feature of Vim (type :help
++ clientserver in Vim for more info) using external processus to control the
++ embedded Vim. That was running quite fine, but was slow :/
++ We changed that :)
++ Now we communicate directly from the kpart to the embedded Vim thanks to X11
++ without using externals processus. That's much faster and reliable ;)
++ KVim has also another remote control system using KDE's DCOP communication
++ backend.
++ Currently I would advice people to use DCOP when running KVim and using X11
++ communication with GVim (DCOP won't work with GVim anyway).
++ There may be some differences in speed, though I have not noticed it here.
++ The most important difference is that DCOP provides a signal system and that can
++ make a difference to improve the interaction between KVim and the hosting
++ application (KDevelop for example). But it's not yet used.
+  
++ Hope you'll enjoy Vim inside KDE :)

+Yes, that's really a Vim Komponent :)
+Yes, you can have Vim inside KDE apps, you guessed it :)
+a115 40
+So, it's designed for KDE 3.x (if someone wants to port it to KDE 2 that
+should be easy), it uses GVim or KVim (even Motif Vim works) 6.x.
+It can be used in different apps : 
+	- KDevelop (version 3)
+	- Konqueror (as a file viewer)
+	- KWrite
+	- KMail (coming in KDE 3.2)
+	- Kompare, KBabel ........ ;)
+
+CONFIGURATION
+=============
+once you compiled and installed it as any other app, 
+start your KDE Control Center, go to the file manager section
+and open the Vim Component configuration module.
+Here, you have to select a Vim executable which may be found on 
+your computer (generally /usr/bin/vim) will do it fine for most

+-						Vim KPart
+-
+-
+-									by Philippe Fremy <[email protected]>
+-
+-
+-Okay, I made it : a Vim KPart!
+-
+-This means that you can have Vim embedded inside Konqueror, and everywhere a
+-text ReadWrite or ReadOnly KPart is requested. Actually, there is almost no
+-place right now where this is the case in KDE. KMail uses its own editor,
+-KDEvelop uses its own editor, Kate uses some more powerful Kate component.
+-
+-But this only the beginning. Enabling a part in those programs shouldn't be
+-much hassle and you can probably help me do it. My hope is really to get
+-KDevelop use Vim.
+-
+-
+-======= OBSOLETE ===========
+-Requirements:
+--------------
+-To make this KPart work, you need a graphicial Vim version 6 with the client-server stuff feature activated and with the vim60-vimpart-patch.diff applied. The patch is in this dir. I hope to get it into the main Vim tree.  KVim has already the patch but is slightly less stable that the original GVim.  A big advantage of KVim is that you get the native KDE dialogs when vim asks a question.
+-
+-
+-======= OBSOLETE ===========
+-Installation:
+--------------
+-To make your vimpart work, you'll have to go into the vimpart directory and run "testVim your_patched_vim". If the test does work, a file goodVim will be created. You will be able to install and use the component. Else, the test will report why it fails (features missing in vim).
+-
+-
+-
+-======= OBSOLETE ===========
+-Testing:
+---------
+-If you want to see your component without installing it, you can do the
+-following:
+-
+-1. configure, build. Then go into the Vimpart subdirectory.
+-
+-2. Include the current Vimpart directory in your KDEDIRS:
+-export KDEDIRS=`pwd`:$KDEDIR
+-
+-3. Symlink .libs to lib
+-ln -s .libs lib
+-
+-4. Create pseudo share/services dir:
+-mkdir share; mkdir share/services;
+-
+-5. Symlink to Vimpart.desktop:
+-ln -s Vimpart.desktop share/services/Vimpart.desktop
+-
+-6. Create a pseudo share/config dir
+-mkdir share/config;
+-
+-7. Symlink to vimwidgetrc
+-ln -s vimwidgetrc share/config/vimwidgetrc
+-
+-8. Update the desktop mimetype database:
+-kbuildsycoca
+-
+-To test it, run VimPartShell. Or run konqueror from this dir and click on a
+-text file.
+-
+-
+-======= OBSOLETE ===========
+-Remarks:
+---------
+-The initial preference of the Vim KPart is 10. Kate uses 8, so if you install the part, it will override Kate for all the mimetypes. You can always change that by manually editing the initial preference in the desktop file or by simply selecting which editor you prefer for which mimetype in the control center.
+-
+-If you find some mimetype not handled by the Vim KPart although they should be, send me a patch!
+-
+-
+-
+-How it works:
+--------------
+-At the beginning, we started to write KVim, a port of GVim to KDE to make
+-it possible to embed Vim inside KDE. But with the latest version of Vim, it
+-turns out that it is not necessary to have a native Vim.
+-
+-
+-I use QXembed, a widget which can embed any X application if it knows its X Window Id, using some X feature.  The patch I provide will make vim displays its window id on stdout when the window is mapped. GVim 6.0 then provides a way to send commands to a Vim window from another process. If you look at the VimWidget source, you will see that 70% of the code is there to handle the communication process. The rest uses the communication channel to send the vim commands needed by kpart and ktexteditor.
+-
+-As far as I can tell, the part is race-condition free. If you issue many sendNormalCmd and many evalExpr, they are guaranted to be executed sequentially. This has caused me enough problems when it wasn't the case!
+-
+-
+-Qt, KDE2 and KDE3:
+-------------------
+-The VimWidget itself depends very litle on KDE. It is quite easy to port remove the KDE specific stuff, to use it in a Qt only program. In fact, at the beginning, it was only Qt-based.
+-
+-
+-
+-======= OBSOLETE ===========
+-Features & TODO:
+-----------------
+-I think most basic features required by an editor widget or part are supported. There are some possible improvement but I would like more feedback to know what really needs to be done. So don't hesitate to write me about your feelings using this.
+-
+-My TODO list is:
+-- restore the editing mode after sendCmd
+-- implement KTextEditor interface
+-- add some useful actions to the part (like search, ...)
+-

++and open the Vim Component configuration module.
++Here, you have to select a Vim executable which may be found on 
++your computer (generally /usr/bin/vim) will do it fine for most
++linux distributions. All you need is that it's a GUI-enabled Vim 6.0 or
++better.
++Push the test button, if that's okay then that's should be enough to start

++
++FUNCTIONMENT
++============
++Philippe Fremy ([email protected]) wrote the initial version of this kpart.
++The concept is to start a normal GUI Vim (like gvim), then "embeds" the Vim
++window into a KDE Widget.
++It used to be based on the ClientServer feature of Vim (type :help
++clientserver in Vim for more info) using external processus to control the
++embedded Vim. That was running quite fine, but was slow :/
++We changed that :)
++Now we communicate directly from the kpart to the embedded Vim thanks to X11
++without using externals processus. That's much faster and reliable ;)
++KVim has also another remote control system using KDE's DCOP communication
++backend.
++Currently I would advice people to use DCOP when running KVim and using X11
++communication with GVim (DCOP won't work with GVim anyway).
++There may be some differences in speed, though I have not noticed it here.
++The most important difference is that DCOP provides a signal system and that can
++make a difference to improve the interaction between KVim and the hosting
++application (KDevelop for example). But it's not yet used.
+ 
++Hope you'll enjoy Vim inside KDE :)
