+# 3p-SDL
+
+This is a fork of [Alchemy's](https://www.alchemyviewer.org/) [3p-SDL2](https://git.alchemyviewer.org/alchemy/thirdparty/3p-sdl2)
+repository configured to build and package using [autobuild](https://wiki.secondlife.com/wiki/Autobuild).
+
+[Simple DirectMedia Layer](SDL/docs/README.md) is a cross-platform development library designed
+to provide low level access to audio, keyboard, mouse, joystick, and graphics
+hardware via OpenGL and Direct3D.
+
+# How to build:
+
+* Install [autobuild](https://wiki.secondlife.com/wiki/Autobuild) utility.
+* Invoke autobuild at the command line:
+<pre>
+        autobuild build
+        autobuild package
+</pre>
+
+That will produce a bundled asset of SDL2 libs and header files called something like: `SDL2-2.24.1-linux-012345678.tar.bz2`
