 <pre>! The Test Script
 To drive the various tests, we use the script {{{tests/test.sh}}}. All tests are run under valgrind control if available unless {{{VALGRINDFLAGS=DISABLE}}} is defined.

+Here is the order suggested:
+|00|The test system itself|
+|01..|Infrastructure, package consistency etc.|
+|10..|Basic support library functionality|
+|20..|Higher level support library services|
+|40..|Backend Unit tests|
+|50..|Proc Layer Unit tests|
+|60..|User interface Unit tests (Gui, Scripting)|
+|70..|Unit interaction tests (Backend, Proc, UI, ...)|
+|80..|Functionality tests on the complete program|
+|90..|Optional tests, example code etc.|
