+# Program:  RunSafely.sh

+# Synopsis: This script simply runs another program.  If the program works
+#           correctly, this script has no effect, otherwise it will do things
+#           like print a stack trace of a core dump.  It always returns
+#           "successful" so that tests will continue to be run.
+#
+# Syntax:  ./RunSafely.sh <program> <arguments>
