+Version 0.8:
+  * [Mario Weilguni] 
+	Made it work with Qt 2.0
+	Fixed a lot of layout problems
+	Fixed segfault caused by wrong accelerator in ::changeAccelerators()
+	There are still a few problems with changed color handling,
+	currently outcommented (look for "TODO" if you wish to fix it)	
+	
+Version 0.7:
+  * [Mark Donohoe] Patch from Jake Hamy <jehamby@lightside.com> which
+                     incorporates code from Johanes Plass' GV. This adds
+					 (1) Compressed file support, (2) PDF support 
+					 ( Currently limited by ghostscript's poor handling of
+					 this format )
+  * [Mark Donohoe] Fixed major performance bug which caused gs to be
+                     repeatedly restarted
+  * [Mark Donohoe] Improved print dialog
+				     - Print to file
+				     - Print all, current, marked, or range of pages
+				     - Setup spooler command, printer name
+                     - Reverse order of printing
+  * [Mark Donohoe] Much better keyboard support
+  * [Mark Donohoe] Improved geometry management
+  * [Mark Donohoe] Improved warning and error dialogs
+	
+Version 0.6.3:
+  * [Mark Donohoe] Session management
+  * [Mark Donohoe] Patch from Markus Duda <Duda@physik.rwth-aachen.de> for 
+                     pagelist.
+				     ( Fixes a problem with documents that have named rather
+					 than numbered pages I believe )
+  * [Mark Donohoe] Imporvements to page list interface
+  * [Mark Donohoe] Fixed mix up of Magnification and Orientation on
+                     View Control dialog
+  * [Mark Donohoe] Few geometry management fixes
+  * [Mark Donohoe] New icon
+  
+Version 0.6.1:
+  * [Robert Williams]  Added version.h and ChangeLog
+  * [Robert Williams]  Added -caption "%c" to kghostview.kdelnk

+KGHOSTVIEW for KDE 3.x
+
+This is Tim Theisen's Ghostview program ported to the K
+Desktop Environment. Ghostscript is used to view PostScript
+documents on Unix X11 systems.
+
+REQUIREMENTS
+
+1. GNU ghostscript
+2. KDE 3.x
+
+If ghostscript works for you then so should KGhostview. ghostscript can be obtained
+at http://www.cs.wisc.edu/~ghost/.
+
+Due to security reasons, kghostview works only with recent versions of ghostscript.
+Versions greater or equal to than GNU version 6.53 or GNU version 7.05 should work.
+
+Other versions or implementation of ghostscript may or may not work. In the
+configuration dialog, found under the Settings menu in the app, it
+is possible to configure the interpreter to use.
+

+- Port to KViewShell / KMultiPage
+
+- Progress bar(s) when loading/converting (the latter can be very slow).
+
+- Find dialog.
+
+- Different icons for Read Up and Read Down.
+
+- Use pdftops which comes with xpdf for pdf->ps conversion. It's output 
+  is much better, and it allows the conversion of selected pages, which is
+  important when you want to print a small number of pages from a large
+  document.
+  I don't think I'll switch to pdftops. Ghostscript also has the possibility
+  to convert selected pages only. And for printing its output is fine. 
+
+- Provide more information via statusbar messages. See gsview, for how it 
+  should be.
+
+- Move the page navigation options from the View menu to the Go menu. 
+  Currently Konqueror doesn't merge the Go menu, so that should be fixed first.
+
+- Fit page to view-width, auto-zoom on widget resize.
+
+- Better handling of Orientation and Paper Size choice.
+
+- Continuous and Continuous Facing viewing of pages, like Acroread.
+
+- Find a good solution which helps the user to keep his eyes focused when
+  scrolling (smooth scrolling or using helper lines like gv).
+
+- Fix all the bugs.
+
+
+Done:
+- Scrollbox should show a thumbnail (like kdvi).
+
+- New implementation for the marklist because QTableView won't be in Qt-3.0 
+  anymore. (I'll keep using QTableView, simply because there's no suitable
+  alternative in Qt3.)
+
+- Switch to the DSC parser provided by Ghostscript.

+ *
+ * 
+ * @section window Drawing on a Window
+ *
+ * The GHOSTVIEW environment variable contains the window id of the target
+ * window.  The window id is an integer.  Ghostscript will use the attributes
+ * of the window to obtain the width, height, colormap, screen, and visual of
+ * the window. The remainder of the information is gotten from the GHOSTVIEW
+ * property on that window.
+ *
+ * 
+ * @section pixmap Drawing on a Pixmap
+ *
+ * The GHOSTVIEW environment variable contains a window id and a pixmap id.
+ * They are integers separated by white space.  Ghostscript will use the
+ * attributes of the window to obtain the colormap, screen, and visual to use.
+ * The width and height will be obtained from the pixmap. The remainder of the
+ * information, is gotten from the GHOSTVIEW property on the window.  In this
+ * case, the property is deleted when read.
+ *
+ * 
+ * @section gv_variable The GHOSTVIEW environment variable
+ *
+ * @par parameters: 
+ *     <tt> window-id [pixmap-id] </tt>
+ *
+ * @par scanf format: 
+ *     @code "%d %d" @endcode
+ *
+ * @par Explanation of the parameters
+ *     @li @e window-id: 
+ *         tells Ghostscript where to:
+ *             - read the GHOSTVIEW property
+ *             - send events
+ *         If pixmap-id is not present, Ghostscript will draw on this window.
+ *
+ *     @li @e pixmap-id: 
+ *         If present, tells Ghostscript that a pixmap will be used as the 
+ *         final destination for drawing. The window will not be touched for 
+ *         drawing purposes.
+ *
+ *
+ * @section gv_property The GHOSTVIEW property
+ *
+ * @par type: 
+ *     STRING

+ *     @li @e bpixmap:
+ *         pixmap id of the backing pixmap for the window. If no pixmap is to
+ *         be used, this parameter should be zero. This parameter must be zero
+ *         when drawing on a pixmap.
+ *
+ *     @li <em>orient:</em> 
+ *         orientation of the page. The number represents clockwise rotation 
+ *         of the paper in degrees.  Permitted values are 0, 90, 180, 270.
+ *
+ *     @li <em>llx, lly, urx, ury:</em>
+ *         Bounding box of the drawable. The bounding box is specified in 
+ *         PostScript points in default user coordinates. (Note the word 
+ *         @e drawable. This means that this bounding box is generally not 
+ *         the same as the BoundingBox specified in the DSC. In case 
+ *         DocumentMedia is specified, it is equal to the Media's bounding 
+ *         box.)
+ *
+ *     @li <em>xdpi, ydpi:</em> 
+ *         Resolution of window. (This can be derived from the other 
+ *         parameters, but not without roundoff error. These values are 
+ *         included to avoid this error.)
+ *
+ *     @li <em>left, bottom, top, right (optional):</em>
+ *         Margins around the window. The margins extend the imageable area 
+ *         beyond the boundaries of the window. This is primarily used for 
+ *         popup zoom windows. I have encountered several instances of 
+ *         PostScript programs that position themselves with respect to the 
+ *         imageable area. The margins are specified in PostScript points.  
+ *         If omitted, the margins are assumed to be 0.
+ *
+ * 
+ * @section events Events from Ghostscript
+ *
+ * If the final destination is a pixmap, the client will get a property 
+ * notify event when Ghostscript reads the GHOSTVIEW property causing it to 
+ * be deleted.
+ *
+ * Ghostscript sends events to the window where it read the GHOSTVIEW 
+ * property. These events are of type ClientMessage.  The message_type is set 
+ * to either PAGE or DONE.  The first long data value gives the window to be 
+ * used to send replies to Ghostscript.  The second long data value gives the 
+ * primary drawable. If rendering to a pixmap, it is the primary drawable. 
+ * If rendering to a window, the backing pixmap is the primary drawable. If 
+ * no backing pixmap is employed, then the window is the primary drawable. 
+ * This field is necessary to distinguish multiple Ghostscripts rendering to 
+ * separate pixmaps where the GHOSTVIEW property was placed on the same 
+ * window.
+ *
+ * The PAGE message indicates that a "page" has completed.  Ghostscript will
+ * wait until it receives a ClientMessage whose message_type is NEXT before
+ * continuing.
+ *
+ * The DONE message indicates that Ghostscript has finished processing.
