+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).
