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