+"""
+This test produces three shared libraries:
+
+1. libt-instr.so is instrumented
+2. libt-no-instr1.so is not instrumented
+3. libt-no-instr2.so is compiled with instrumentation enabled, but the object file is built
+ with instrumentation turned off.
+
+After the libraries are built, the main program is then built with/without instrumentation and linked
+against 3 libraries above.
+
+The test is to verify that programs linked against these shared objects with and without instrumentation
+enabled behave as expected.
