   302
     If --dry-run is specified and the checker emits warnings,

alpar@325
   304
     errors.
deba@324
   305
  --werror|-w
alpar@325
   306
     Make all warnings into errors.
deba@324
   307
  --all|-a

   308
     Check all source files in the repository.
deba@324
   309
  --modified|-m
alpar@325
   310
     Check only the modified (and new) source files. This option is
alpar@325
   311
     useful to check the modification before making a commit.
deba@324
   312
  --changed|-c
deba@324
   313
     Check only the changed source files compared to the parent(s) of

     the current hg node.  This option is useful as hg hook script.
alpar@325
