   273      If --dry-run is specified and the checker emits warnings,

   275      errors.

   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,
