268  $0 [OPTIONS] [files]
269Options:
270  --dry-run|-n
271     Check the files, but do not modify them.
272  --interactive|-i
273     If --dry-run is specified and the checker emits warnings,
274     then the user is asked if the warnings should be considered
275     errors.
276  --werror|-w
277     Make all warnings into errors.
278  --all|-a
279     Check all source files in the repository.
280  --modified|-m
281     Check only the modified (and new) source files. This option is
282     useful to check the modification before making a commit.
283  --changed|-c
284     Check only the changed source files compared to the parent(s) of
285     the current hg node.  This option is useful as hg hook script.
286     To automatically check all your changes before making a commit,
287     add the following section to the appropriate .hg/hgrc file.
