To enable the verbose report you can set to non-
nil means to report verbose information on generated parser.
Or interactively use the command:
Toggle whether to report verbose information on generated parser.

where source-file is the name of the Emacs Lisp file from which the grammar was read. See Understanding the automaton, for details on the verbose report.
To help debugging the grammar compiler itself, you can set this variable to print the content of some internal data structures:
nil means enable some debug stuff.
