+Those test cases are designed to test the support for loading and unloading
+probe providers and callsites at run time during tracing. One test case also
+tests the event payload comparaison functions.
+
+Testing build artefacts:
+------------------------
+
+./exec-with-callsites
+ Test binary built with tracepoint callsites
+
+./exec-without-callsites
+ Test binary built without tracepoint callsites
+
+/.libs/libprobe_*.so:
+ Libraries containing slight variations of probe providers for the same
+ tracepoint name. Note that the file /.libs/libprobes_a_prime.so has the same
+ content as .libs/libprobes_a.so likewise for libprobes_c_prime.so
+
+/.libs/libcallsites_*.so
+ Libraries containing tracepoint callsites. The user must dlopen the library
+ and use dlsym to get an handle on the function that calls the tracepoint.
