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

   298   --all|-a

   299      Check all source files in the repository.

   300   --modified|-m

   301      Check only the modified (and new) source files. This option is

   302      useful to check the modification before making a commit.

   303   --changed|-c

   304      Check only the changed source files compared to the parent(s) of

   305      the current hg node.  This option is useful as hg hook script.

   306      To automatically check all your changes before making a commit,
