  20 # Define callbacks and load other libraries.  This file is loaded relatively
  21 # early, and before any other file we write ourselves.  "load_lib" will
  22 # find anything in the DejaGNU installation tree, or in our lib directory.
  23 # "load_gcc_lib" will search the core compiler's .exp collection instead.
  24 #
  25 # The naming rule is that dg.exp looks for "tool-" and runtest.exp looks
  26 # for "tool_" when finding callbacks.  Utility routines we define for
  27 # our callbacks begin with "v3-".
  28 #
  29 # libstdc++_* callbacks we don't define, but could:
  30 # ..._option_help           prints additional --help output
  31 # ..._option_proc (--foo)   process our own options
  32 # ..._init (normal.exp)     called once per test file
  33 # ..._finish                bracketing function for libstdc++_init
  34 # ...-dg-prune              removing output text, see top of system dg.exp
  35 #
  36 # Useful hook:  if ${hostname}_init exists, it will be called, almost
  37 # the last thing before testing begins.  This can be defined in, e.g.,
  38 # ~/.dejagnurc or $DEJAGNU.
