6.4 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.
