       It’s possible to confirm whether the package is installed. Besides, if no packages are given as the
       arguments, check command checks whether there is a package that has not been installed.

       Installation check:

           if ! zplug check --verbose; then
               printf "Install? [y/N]: "
               if read -q; then
                   echo; zplug install
               fi
           fi

       The above code means that the packages will be installed if there is a package that has not been
       installed.

       Installation check from CLI:

           $ zplug check --verbose ´some_author/some_repo´
           - some_author/some_repo: not installed
