7.3.3 Output Information

Options --q…[=NONT] query various types of information before and after processing a training terminal symbol sequence. On passing the option argument NONT, the parser dumps information about a specified nonterminal symbol of a template regular expression grammar. You can pass multiple options --q…=NONT to dump information about multiple nonterminal symbols. If the option argument NONT not supplied, the parser dumps information about all nonterminal symbols.

Options --o…=FILE specify filenames for dumping queried information. If FILE is ‘-’, the parser dumps queried information to stdout. If an option --o…=FILE is present but a corresponding option --q…[=NONT] is absent, the parser dumps information about all nonterminal symbols to FILE. If an option --o…=FILE is absent but a corresponding option --q…[=NONT] is present, the parser dumps queried information to stdout.

Other options might control output modes and additional filtering output information.
