   1 # Explicit GL (XGL) Ecosystem Components\r
   2 *Version 0.2, Spinning Cube, 31 Oct 2014*\r
   3 \r
   4 This project provides *open source* components for the XGL Ecosystem.\r
   5 \r
   6 ## Introduction\r
   7 \r
   8 The components here are being shared with the Khronos community to provide\r
   9 early insights into the specification of XGL and to assists those doing\r
  10 prototyping at this point.\r
  11 \r
  12 The following components are available:\r
  13 - Proposed Reference [*ICD Loader*](https://github.com/KhronosGroup/GL-Next/tree/master/loader) (including [*Layer Management*](https://github.com/KhronosGroup/GL-Next/tree/master/layers/README.md))\r
  14 - Proposed Reference [*Validation Layers*](https://github.com/KhronosGroup/GL-Next/tree/master/layers/)\r
  15   - [Object Tracker](https://github.com/KhronosGroup/GL-Next/blob/master/layers/object_track.c)\r
  16   - [Draw State](https://github.com/KhronosGroup/GL-Next/blob/master/layers/draw_state.c)\r
  17 - *GLAVE Debugger* ([API Dump](https://github.com/KhronosGroup/GL-Next/blob/master/layers/api_dump.c) only)\r
  18 - [*Sample Drivers*](https://github.com/KhronosGroup/GL-Next/tree/master/icd)\r
  19   - [Common Infrastructure](https://github.com/KhronosGroup/GL-Next/tree/master/icd/common)\r
  20   - [Implementation for Intel GPUs](https://github.com/KhronosGroup/GL-Next/tree/master/icd/intel)\r
  21 \r
  22 ## How to Build and Run\r
  23 \r
  24 This release demonstrates a spinning textured cube as an example of the\r
  25 vertical slice of XGL functionality running on Ubuntu 14.10 with an Intel\r
  26 GPU.\r
  27 [BUILD.md](https://github.com/KhronosGroup/GL-Next/tree/master/BUILD.md)\r
  28 includes directions for building all the components, running the validation tests and running the demo applications.\r
  29 \r
  30 Information on how to enable the API Dump and Validation layers is in\r
  31 [layers/README.md](https://github.com/KhronosGroup/GL-Next/tree/master/layers/README.md).\r
