289Options:
290  --dry-run|-n
291     Check the files, but do not modify them.
292  --interactive|-i
293     If --dry-run is specified and the checker emits warnings,
294     then the user is asked if the warnings should be considered
295     errors.
296  --werror|-w
297     Make all warnings into errors.
298  --all|-a
299     Check all source files in the repository.
300  --modified|-m
301     Check only the modified (and new) source files. This option is
302     useful to check the modification before making a commit.
303  --changed|-c
304     Check only the changed source files compared to the parent(s) of
305     the current hg node.  This option is useful as hg hook script.
306     To automatically check all your changes before making a commit,
307     add the following section to the appropriate .hg/hgrc file.
