+SDL on Sony Playstation3
+------------------------
+
+Installation:
+  First, you have to install the Cell SDK
+  - Download the Cell SDK installer RPM and ISO images to
+    a temporary directory such as /tmp/cellsdk.
+  - Mount the image: mount -o loop CellSDK-Devel-Fedora_3.1.0.0.0.iso /tmp/cellsdk
+  - Install the SDK installer: rpm -ivh cell-install-3.1.0-0.0.noarch.rpm
+  - Install the SDK: cd /opt/cell && ./cellsdk --iso /tmp/cellsdkiso install
+
+  You'll than need to install the SPU-libs
+  - Run make ps3-libs && make ps3libs-install
+
+  Finally, install SDL
+  - Go to SDL-1.2/ and build SDL like any other GNU style package.
+  e.g.
+    - Build the configure-script with ./autogen.sh
+    - Configure SDL for your needs: ./configure --enable-video-ps3 ...
+    - Build and install it: make && make install
+
+
+Todo:
+  - Mouse & Keyboard support
+  - On SPU-side the current scaler and converter restrictions are:
+    - resolution has to be a multiple of 8 (will work on that)
+    - scaler/converter only supports the YV12 and IYUV format
+    - the scaler works only bilinear (lanzos would be nice)
+  - Optimize the SPU-program handling on the PPE side
+  - Integrate spumedia in SDL
+
+Have fun!
