  $0 [OPTIONS] [files]

Options:

  --dry-run|-n

     Check the given files, but do not modify them.

  --interactive|-i

     prompted whether the warnings should be turned to errors.

  --werror|-w

  --all|-a

  --modified|-m

     Check only the modified source files. This option is proper to

     use before a commit. E.g. all files which are modified or added

     into the repository will be updated.

  --changed|-c

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

     the current hg node.  This option is proper to use as hg hook

     script. E.g. to check all your commited source files with this

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

     file.

       [hooks]

  --help|-h
