-# ..._option_help           prints additional --help output
-# ..._option_proc (--foo)   process our own options
-# ..._init (normal.exp)     called once per test file
-# ..._finish                bracketing function for libstdc++_init
-# ...-dg-prune              removing output text, see top of system dg.exp
-#
-# Useful hook:  if ${hostname}_init exists, it will be called, almost
-# the last thing before testing begins.  This can be defined in, e.g.,
