      `--version` will print the version to STDOUT, and if a newer version is available it will print out an update message to STDERR.

      You can optionally specify a version number as a second argument, in which case  will compare the current version with that version exit with code 1 if the current version is less than the provided version. It will exit with code 0 if the current version is less than, or equal to the provided version.
