+# This test tests the restoration of various kinds of machine state
+# to their original values with a process record log. We will execute
+# the program forward while it changes various types of data, and
+# then execute it backward to see if their values get restored.
+#
+# The types of machine state (data) that are tested are:
+# register variable
+# auto variable
+# function static variable
+# module static variable
+# module global variable
+#
+# TODO:
+# various, possibly including...
+# .bss variable, .data variable, ...
+# shared library variable
+# heap variable (pointer)...
+# overlay variables...
+# Test forward replay
+#
+
+# This test suitable only for process record-replay
