Hi! I use zsh and have a little knowledge about zsh completion.
Like this: (this file should be /usr/share/zsh/site-functions/_hello)
```
#compdef hello
_arguments -s '(- *)'{-h,--help}'[display this help and exit]' \
'(- *)'{-v,--version}'[display version information and exit]' \
{-t,--traditional}'[use traditional greeting]' \
{-g,--greeting=}'[use TEXT as the greeting message]:TEXT'
```
How about add a completion for hello?
Thanks!
