Solve the following python programming problem given the following code:
def command_setup(self, * args) : 
    'Defines a new sftp file system configuration or edits an old one with the same id.
        Usage: sftpman setup {options}
        Available {options}:
            --id={unique system identifier}
                You use this to recognize and manage this sftp system.
                It determines what the local mount point is.
                If `--id=example`, the filesystem will be mounted to: `/mnt/sshfs/example`
            --host={host to connect to}
            --port={port to connect to} [default: 22]
            --user={username to authenticate with} [default: current user]
            --mount_opt={option to pass to sshfs} [optional] [can be passed more than once]
                Example: --mount_opt="follow_symlinks" --mount_opt="workaround=rename"
                `sshfs --help` tells you what sshfs options are available
            --mount_point={remote path to mount}
            --auth_method={method}
                Specifies the authentication method.
                Can be `password` or `publickey`. [default: publickey]
            --ssh_key={path to the ssh key to use for authentication}
                Only applies if auth_method is `publickey`.
            --cmd_before_mount={command to run before mounting} [default: /bin/true]
                Allows you to run a custom command every time this system is mounted.
        ' 
    def usage() : 
        print (self.command_setup.__doc__) 
        sys.exit (1) 
if (len (args) == 0) : 
        usage () 
try : 
        fields = ['id', 'host', 'port', 'user', 'mount_opt', 'mount_point', 'ssh_key', 'cmd_before_mount', 'auth_method']

        sys.stderr.write (('Error: %s

' % e)) 
        usage () 
system = SystemModel () 
    mount_opts = [] 
    for (name, value) in self : 
        name = name.lstrip ('-') 
        if (not hasattr (system, name)) : 
            continue 
if (name == 'mount_opt') : 
   ...
