+NOTES:
+- This includes all the audio targets except arts, because Ubuntu pulled the 
+  artsc0-dev package, but in theory SDL still supports it.
+- DirectFB isn't included because the configure script (currently) fails to find
+  it at all. You can do "sudo apt-get install libdirectfb-dev" and fix the 
+  configure script to include DirectFB support. Send patches.  :)
