"Usage:

  $0 [OPTIONS] [files]

Options:

  --dry-run|-n

     Check the files, but do not modify them.

  --interactive|-i

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

     then the user is asked if the warnings should be considered

     errors.

  --werror|-w

     Make all warnings into errors.

  --all|-a

     Check all source files in the repository.

  --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.

       [hooks]

       pretxncommit.checksources = scripts/unify-sources.sh -c -n -i

  --help|-h

     Print this help message.

  files

     The files to check/unify. If no file names are given, the modified

     source files will be checked/unified (just like using the

     --modified|-m option).
