+# Wrapper around CTest for DUNE
+#
+# CTest returns with an error status not only when tests failed, but also

+# successfully if no tests failed; skipped tests do not result in an error.
+# This behaviour is needed in a continuous integration environment, when
+# building binary packages or in other cases where the testsuite should be
+# run automatically.
+#
+# Moreover, this script also converts the XML test report generated by CTest
+# into a JUnit report file that can be consumed by a lot of reporting
+# software.
