+-------------------------------------------------------------------------------
+version 0.3.0: Date 1999-07-13
+
+* Graphics:
+  - Switched to one single image resolution
+  - Converted images to PNG and JPEG formats
+  - The window can now be resized freely - graphics is scaled to fit window
+  - Graphics now looks MUCH better on 256 colour displays
+  - Improved wall graphics (several stones with different textures)
+  - Removed status bar - now draws info directly in widget (not perfect yet)
+
+* New experimental feature:
+  - It is now possible to load external level collections from text files
+
+* Some changes related to KDE 2.0 / Qt 2.0
+  - replaced many char * with QString
+  - uses KStandardDirs instead of localkdedir
+
+* Some minor bugfixes/cleanups
+
+-------------------------------------------------------------------------------
+version 0.2.2: Date 1998-11-06
+
+* Bugfix: "Animation off" now works again
+
+* Possibly fixed bug: Settings should now always be saved properly
+	I haven't been able to reproduce this bug, but it has been reported
+	that the settings would sometimes not be saved to the right section
+	in the config file. Thanks to Tore Skaug <toresk@pvv.ntnu.no> for
+	reporting this.
+
+* Now uses the zlib check in acinclude
+                   
+-------------------------------------------------------------------------------
+version 0.2.1: Date 1998-10-25
+
+* Bugfix: Fixed failed assertion that showed up if you changed to small
+          graphics and restarted the game.
+          Thanks to Bernd Weber <bernd.weber@systemhaus.net> for reporting
+          this.
+
+* No longer requires zlib. It is still used if found, though.
+
+-------------------------------------------------------------------------------
+version 0.2.0: Date 1998-10-15
+
+New features:
+
+* Bookmarks
+* Animation speed menu
+* Status bar
+* Internationalisation
+
+-------------------------------------------------------------------------------
+version 0.1.2: ksokoban imported to CVS. Date 1998-08-30
+
+-------------------------------------------------------------------------------
+version 0.1.1: bugfix release. Date 1998-08-25
+
+* BUGFIX: ksokoban now ignores mouseclicks while a move is in progress.
+	  Previously such a click would cause a memory leak and a corrupted
+	  undo/redo history (or a failed assertion if debugging was turned on).
+	  Thanks to Natali Giuliano <natali@stone.trew.it> for reporting this.
+
+* ksokoban should now work with older zlib & Qt libraries.
+  I have tested it with zlib 1.0.3 and Qt 1.33
+
+* Detects the old gcc 2.7 and turns off optimisations if it is found.
+  It might work with the gcc 2.7 now. No promises, though.
+  I can only test it with gcc 2.8 and egcs/pgcc.

+
+------------------------------------------------------------------------
+
+PLAYING
+=======
+
+The objective of the game is to push all the red gems (these should
+actually have been crates, but gems looked nicer) to the goal squares,
+which are marked with green glassy things on the floor.
+
+Use the cursor keys to move about. If you move onto a gem and there is
+noting blocking it on the opposite side, then you will push the gem.
+
+Use the CONTROL key together with the cursor keys to move as far as
+possible in a direction without pushing any gems. With the SHIFT key
+you will move as far as possible in a direction, possibly pushing a
+gem if it is in the way.
+
+Use the left mouse button to move to any place you can reach without
+pushing any gems. The middle mouse moves in a straight line, possibly
+pushing a gem if it is in the way.
+
+The U key or the right mouse button undoes the last move.
