+# Run herd tests on all .litmus files in the specified directory (which
+# defaults to litmus-tests) and check each file's result against a "Result:"
+# comment within that litmus test. If the verification result does not
+# match that specified in the litmus test, this script prints an error
+# message prefixed with "^^^". It also outputs verification results to
+# a file whose name is that of the specified litmus test, but with ".out"

+#
+# Usage:
+# sh checkalllitmus.sh [ directory ]
+#
+# The LINUX_HERD_OPTIONS environment variable may be used to specify
+# arguments to herd, whose default is defined by the checklitmus.sh script.
+# Thus, one would normally run this in the directory containing the memory
+# model, specifying the pathname of the litmus test to check.
+#
+# This script makes no attempt to run the litmus tests concurrently.
