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