			 DStress is a collection of bug tracking and language conformance test cases for the <a href="http://digitalmars.com/d/">D programming language</a>. This document describes the use of the testing framework. The test summary can be found at <a href="./www/dstress.html">http://dstress.kuehne.cn/www/dstress.html</a>.</p>
