   298   --modified|-m

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

   300      useful to check the modification before making a commit.

   301   --changed|-c

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

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

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