27 # for "tool_" when finding callbacks. Utility routines we define for
28 # our callbacks begin with "v3-".

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