Query vuls version

What did you expect to happen?

Run command "vuls flags -v" can get vuls version

What happened instead?

• Current Output [root@localhost ~]# vuls flags -v Show version [root@localhost ~]# echo $? 0 [root@localhost ~]# vuls flags -v flag provided but not defined: -v flags [<subcommand>]:

    With an argument, print all flags of <subcommand>. Else,
    print a description of all known top-level flags.  (The basic
    help information only discusses the most generally important
    top-level flags.)

  [root@localhost ~]# echo $? 2

Please re-run the command using -debug and provide the output below.
