287  --interactive|-i
288     If --dry-run is specified and the checker emits warnings,
289     then the user is asked if the warnings should be considered
290     errors.
291  --werror|-w
292     Make all warnings into errors.
293  --all|-a
294     Check all source files in the repository.
295  --modified|-m
296     Check only the modified (and new) source files. This option is
297     useful to check the modification before making a commit.
298  --changed|-c
299     Check only the changed source files compared to the parent(s) of
300     the current hg node.  This option is useful as hg hook script.
301     To automatically check all your changes before making a commit,
