 This operation has the following options:

     Checks that the contents of every valid store path has not been
     altered by computing a SHA-256 hash of the contents and comparing it
     with the hash stored in the Nix database at build time. Paths that

     `--check-contents` is given) the contents of a valid path has been
     modified, then try to repair the path by redownloading it. See
