This has been released under the Boost license and is available at <a href="https://github.com/facebook/warp">https://github.com/facebook/warp</a>.</p> <p>The Facebook blog makes the following statement with regards to  improved efficiency over the GCC preprocessor</p> <blockquote> <p>Replacing gcc&rsquo;s preprocessor with <code>warp</code> has led to significant improvements of our end-to-end build times (including linking). Depending on a variety of circumstances, we measured debug build speed improvements ranging from 10% all the way to 40%, all in complex projects with massive codebases and many dependencies</p> </blockquote>
