Git Subcommand Aliasing

You can map Aviator CLI command as git subcommand. In your .gitconfig, you can add aliases:
# Do not forget an exclamation point before av.
sync = !av stack sync
tree = !av stack tree
pr = !av pr
With the config above, git sync will execute av stack sync.
This utilizes a feature that git provides. You can see the details in git-config(1).
