+This project was build with an old version of GLFW. It still works
+mostly as-is if you clone the GLFW legacy code and build the old
+version from source. Then symlink the `include` and `lib` directories
+like this:
+
+	ln -s path/to/glfw-legacy/include ./include
+	ln -s path/to/glfw-legacy/lib/x11 ./lib
 
 Feel free to use this code (although right now, it's kind of poorly organized...all in one big file).
