+# Apparently, there's simply no way to ask GDB to exit with a non-zero
+# status when the script run with the --eval-command option fails. Thus, if
+# we have --eval-command run prologue.py directly, syntax errors there will
+# lead GDB to exit with no indication anything went wrong.
+#
+# To avert that, we use this very small launcher script to run prologue.py
+# and catch errors.
+#
+# Remember, errors in this file will cause spurious passes, so keep this as
+# simple as possible!
