+<h2>Compiler Validation</h2>

+<p>
+A new <a href="http://glean.sf.net" target="_parent">Glean</a> test has
+been create to exercise the GLSL compiler.
+</p>
+<p>
+The <em>glsl1</em> test runs over 130 sub-tests to check that the language
+features and built-in functions work properly.
+This test should be run frequently while working on the compiler to catch
+regressions.
+</p>
+<p>
+The test coverage is reasonably broad and complete but additional tests
+should be added.
