Options:

  --dry-run|-n

     Check the files, but do not modify them.

     then the user is asked if the warnings should be considered

     errors.

  --werror|-w

     Make all warnings into errors.

  --all|-a

  --modified|-m

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

     useful to check the modification before making a commit.

  --changed|-c

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

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

     To automatically check all your changes before making a commit,

     add the following section to the appropriate .hg/hgrc file.
