+- @ref zunitc - Simple test framework
+
+@section tools_overview Overview
+
+The tools area currently consists of one sub-project (@ref zunitc) that is
+refined from the prior single weston/tests source folder.
+
+@subsection tools_overview_old Old Code Organization
+
+The original 'tests' folder contained basic weston testing with an
+integrated test runner framework. Over time things progressed to the
+stage where splitting apart into discrete layers was warranted.
+
+@dotfile tools_arch_old.gv "Original test code organization"
+
+@subsection tools_overview_new New Code Organization
+
+The test code that is not weston-specific gets split out to a separate
+folder and/or folders.
