"Usage:
  $0 [OPTIONS] [files]
Options:
  --dry-run|-n
     Check the given files, but do not modify them.
  --interactive|-i
     If --dry-run is specified and files are warned, then a message is
     prompted whether the warnings should be turned to errors.
  --werror|-w
     If --dry-run is specified, the warnings are turned to errors.
  --all|-a
     Check all source files in the repository.
  --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]
       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).
