+    depending on what was found:
+
+        If a suite is matched first, then only the suite is selected. The
+        suite may be marked manual.
+
+        If a module is matched first, then only suites from that module
+        and library not marked manual are selected from then on.
+
+        If a library is matched first, then only suites from that library
+        not marked manual are selected from then on.
