# 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 prolog.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 prolog.py
# and catch errors.
#
# Remember, errors in this file will cause spurious passes, so keep this as
# simple as possible!
