  --werror|-w
alpar@337
   306
     Make all warnings into errors.

   308
     Check all source files in the repository.
deba@336
   309
  --modified|-m
alpar@337
   310
     Check only the modified (and new) source files. This option is

   311
     useful to check the modification before making a commit.
deba@336
   312
  --changed|-c
deba@336
   313
     Check only the changed source files compared to the parent(s) of
