+==============================================================================
+Using the Simple DirectMedia Layer with Qtopia/OPIE
+==============================================================================
+
+==============================================================================
+I.  Setting up the Qtopia development environment.
+
+  This document will not explain how to setup the Qtopia development
+  environment. That is outside the scope of the document. You can read
+  more on this subject in this excellent howto:
+
+	http://www.zauruszone.com/howtos/linux_compiler_setup_howto.html
+
+==============================================================================
+II.  Building the Simple DirectMedia Layer libraries using the arm
+     cross-compiler
+
+  This is somewhat tricky since the name of the compiler binaries
+  differ from the standard. Also you should disable features not
+  needed. The command below works for me. Note that it's all one
+  line. You can also set the NM, LD etc environment variables
+  separately.
+
+	NM=arm-linux-nm LD=arm-linux-ld CC=arm-linux-gcc CXX=arm-linux-g++ RANLIB=arm-linux-ranlib AR=arm-linux-ar ./configure --enable-video-qtopia --disable-video-dummy --disable-video-fbcon  --disable-video-dga --disable-arts --disable-esd --disable-alsa --disable-cdrom --disable-video-x11 --disable-nasm --prefix=/opt/Qtopia/sharp/ arm-unknown-linux-gnu
+
+  One thing to note is that the above configure will include joystick
+  support, even though you can't have joysticks on the Zaurus. The
+  reason for this is to avoid link / compile / runtime errors with
+  applications that have joystick support.
+
+==============================================================================
+III.  Building the Simple DirectMedia Layer test programs:
+
+  After installing, making sure the correct sdl-config is in your
+  path, run configure like this:
+
+	NM=arm-linux-nm LD=arm-linux-ld CC=arm-linux-gcc CXX=arm-linux-g++ AR=arm-linux-ar ./configure arm-unknown-linux-gnu
+
+==============================================================================
+IV.  Application porting notes
+
+  One thing I have noticed is that applications sometimes don't exit
+  correctly. Their icon remains in the taskbar and they tend to
+  relaunch themselves automatically. I believe this problem doesn't
+  occur if you exit your application using the exit() method. However,
+  if you end main() with 'return 0;' or so, this seems to happen.
+
+  Also note that when running in landscape mode - i.e requesting a
+  window that is HEIGHT pixels wide and WIDTH pixels high, where WIDTH
+  and HEIGHT normally is 240 and 320 - the image is blitted so that
+  the hardware buttons are on the left side of the display. This might
+  not always be desirable but such is the code today.
+
+
+==============================================================================
+V.  Enjoy! :)
+
+  If you have a project you'd like me to know about, or want to ask questions,
+  go ahead and join the SDL developer's mailing list by sending e-mail to:
+
+	sdl-request@libsdl.org
+
+  and put "subscribe" into the subject of the message. Or alternatively you
+  can use the web interface:
+
+	http://www.libsdl.org/mailman/listinfo/sdl
+  
+==============================================================================
+VI.  What is supported:
+
+Keyboard (Sharp Zaurus)
+Hardware buttons
+Stylus input (mouse)
+Video. Allows fullscreen both in portrait mode (up to WIDTHxHEIGHT
+size window) and in landscape mode (up to HEIGHTxWIDTH). 
+
+All other SDL functionality works like a normal Linux system (threads,
+audio etc).
