+	help
+	  Enabling this option will compile and install the uClibc-ng
+	  test suite. This is useful if you want to check if the
+	  uClibc-ng library is working for your architecture and/or
+	  help developing uClibc-ng.
+
+	  The test suite will be installed into
+	  /usr/lib/uclibc-ng-test directory. To run the test suite
+	  enter the /usr/lib/uclibc-ng-test/test directory and type
+	  "sh uclibcng-testrunner.sh".
+
+	  See the /usr/lib/uclibc-ng-test/test/README for additional
+	  information.
+
+	  This is not needed at all for normal builds, so you can
+	  safely say no if you do not plan to dig into your C library.
+
+	  The tests can also be used for GNU libc or musl.
