       "App::CLI" dispatches CLI (command line interface) based commands into command classes.
       It also supports subcommand and per-command options.

       get_opt([@config], %opt_map)

           give options map, process by Getopt::Long::Parser

       interface of dispatcher


       find package name of subcommand in constant %alias

       if it's finded, return ucfirst of the package name,

       otherwise, return ucfirst of $cmd itself.

       get_cmd($cmd, @arg)

       return subcommand of first level via $ARGV[0]
