+Source layout and architecture of the Gallium D3D state tracker
+
+w32api is a link to Wine's include files for the Windows API 
+d3dapi contains the headers for Direct3D 10.0, 10.1 and 11.0 (independently created, except d3d10 which is based on Wine)
+gd3dapi contains the Gallium COM state tracker API and extensions to the DXGI and Direct3D APIs, both for internal and external usage
+d3d1xshader is a standalone module with a parser, disassembler and utility routines for Direct3D 10/11 shaders using Shader Model 4/5 instructions encoded using Tokenized Program Format embedded in a DXBC chunked container (the data format produced by the HLSL compiler).
+mstools contains a downloader for the Microsoft HLSL compiler
+tools contains the shader compiler, currently wrapping the Microsoft HLSL compiler
+gd3d10 contains the implementation of Direct3D 10 and 10.1 with Gallium-specific entry points
+gd3d11 contains the implementation of Direct3D 11 with Gallium-specific entry points
+gd3d1x contains the shader translator and code not directly implementing Direct3D interfaces, but needed by those implementations
+dxgid3d10 contains the DXGI-based "official" entry points to Direct3D 10.0 and 10.1
+dxgid3d11 contains the DXGI-based "official" entry points to Direct3D 11
+dxgi contains the implementation of DXGI (currently over the EGL native interface)
+d3d1xstutil contains helper code shared among all the modules in the state tracker 
+programs contains the Gallium Direct3D 11 demos, runnable either on the Microsoft or Gallium implementations
+docs contains documentation
