+# In some environments, $AR will generate a warning message to stderr
+# if the library doesn't previously exist and is being created. One
+# way to fix this is to tell AR to be quiet (sometimes the 'c' flag),
+# but this is difficult to do in a platform-/implementation-specific
+# method. Instead, we will use the following as a stderr match for
+# tests that use AR so that we will view zero or more "ar: creating
+# <file>" messages to be successful executions of the test (see
+# test/AR.py for sample usage).
