+# amd64 Linux to NaCl.
+
+# The final tarball can be unpacked in the root directory of a RPi,
+# so the SDL2 install lands in /usr/local. Run ldconfig, and then
+# you should be able to build and run SDL2-based software on your
+# Pi. Standard configure scripts should be able to find SDL and
+# build against it, and sdl2-config should work correctly on the
+# actual device.
