Solve the following python programming problem given the following code:
def manage(commands, argv = None, delim = ':') : 
    '
    Parses argv and runs neccessary command. Is to be used in manage.py file.

    Accept a dict with digest name as keys and instances of
    :class:`Cli<iktomi.management.commands.Cli>`
    objects as values.

    The format of command is the following::

        ./manage.py digest_name:command_name[arg1[arg2[...]]][--key1=kwarg1[...]]

    where command_name is a part of digest instance method name, args and kwargs
    are passed to the method. For details, see
    :class:`Cli<iktomi.management.commands.Cli>` docs.
