+# This test case is to test the performance of GDB when it is handling
+# the shared libraries of inferior are loaded and unloaded.
+# There are two parameters in this test:
+#  - SOLIB_COUNT is the number of shared libraries program will load
+#    and unload
+#  - SOLIB_DLCLOSE_REVERSED_ORDER controls the order of dlclose shared
+#    libraries.  If it is set, program dlclose shared libraries in a
+#    reversed order of loading.
