 Saving debugging output
 =======================
 
    Debug and tracing output can be redirected to files using either the
 `-o' option to `m4', or with the builtin macro `debugfile':
 
      debugfile(opt FILENAME)
 
 will send all further debug and trace output to FILENAME.  If FILENAME
 is empty, debug and trace output are discarded and if `debugfile' is
 called without any arguments, debug and trace output are sent to the
 standard error output.
