class ExitCode(IntEnum):
    """The following exit codes are defined and can be used with SystemExit, although they
    are not required. These are typically used for system programs written in Python,
    such as a mail server’s external command delivery program.

    * EX_OK: Exit code that means no error occurred.
    * EX_USAGE: Exit code that means the command was used incorrectly, such as when the wrong number of arguments are given.
    * EX_DATAERR: Exit code that means the input data was incorrect.
    * EX_NOINPUT: Exit code that means an input file did not exist or was not readable.
    * EX_NOUSER: Exit code that means a specified user did not exist.
    * EX_NOHOST: Exit code that means a specified host did not exist.
    * EX_UNAVAILABLE: Exit code that means that a required service is unavailable.
    * EX_SOFTWARE: Exit code that means an internal software error was detected.
    * EX_OSERR: Exit code that means an operating system error was detected, such as the inability to fork or create a pipe.
    * EX_OSFILE: Exit code that means some system file did not exist, could not be opened, or had some other kind of error.
    * EX_CANTCREAT: Exit code that means a user specified output file could not be created.
    * EX_IOERR: Exit code that means that an error occurred while doing I/O on some file.
    * EX_TEMPFAIL: Exit code that means a temporary failure occurred. This indicates something that may not really be an error, such as a network connection that couldn’t be made during a retryable operation.
    * EX_PROTOCOL: Exit code that means that a protocol exchange was illegal, invalid, or not understood.
    * EX_NOPERM: Exit code that means that there were insufficient permissions to perform the operation (but not intended for file system problems).
    * EX_CONFIG: Exit code that means that some kind of configuration error occurred.
    * EX_NOTFOUND: Exit code that means something like "an entry was not found".
