The files in this directory go in the "handmade/code" directory
for Day 011 of Handmade Hero. In particular, it _will not compile_
without the handmade.h and handmade.cpp files from the Day 011 source.

They correspond to Chapter 11 of the Handmade Penguin tutorial at
http://davidgow.net/handmadepenguin/ch11.html

"sdl_handmade.cpp" is the version with the custom ringbuffer can be compiled with:
./build.sh

"sdl_handmade_queueaudio.cpp" is the version using SDL_QueueAudio(), and can be
compiled with:
./build-queueaudio.sh

Both versions produce a ./handmadehero binary.

A custom copy of SDL is used for the SDL_QueueAudio() version. As a result,
it will not work if the binary is moved to another directory, unless your system
version of SDL2 supports the SDL_QueueAudio() function.

Don't bug Casey about this code, the bugs in it are David Gow's
fault, and should be reported to <david@ingeniumdigital.com>

Enjoy,
