+# This patch allows running the game on systems without OpenGL support.
+#
+# It modifies the video portion of the SuperTux engine to render all graphics
+# with SDL functions only. Many features are removed from the video engine,
+# so don't expect much.
+#
+# Note that the patched sources will need an additional library, SDL_gfx, to
+# compile.
+#
+# Installing the patch should be pretty straightforward. Simply run the
+# following command prior to running autogen.sh and configure:

+ Also, notice that SuperTux saves the options, so it's often enough to
+ specify them once.

+- The game uses OpenGL to render the graphics. You will either need a CPU
+- with about 10 GHz or an accelerated video card with the vendor's drivers.
+- (On Linux, the team recommends using cards from NVidia with the proprietary
+- drivers, but ATI or another verndor should do.)
++ The game uses SDL to render the graphics. You will either need a CPU
++ with about 1 GHz or go get the original version of SuperTux which uses
++ OpenGL.
