  28     NAME
  29         Tout - Print surrogate debug output
  30
  31     SYNOPSIS
  32         void Tout(char *subname, char *msg, ...)
  33
  34     DESCRIPTION
  35         Tout prints debugging output if surrogate tracing
  36         has been turned on (-T specified). The message will
  37         also go to the debug output if debugging is turned
  38         on (-x specified). The subroutine name is printed
  39         if it is not a null string.
