static USAGE: &str = "
Print script parts necessary to activate xan completions, tailored
to your current shell.

Only support `bash` and `zsh` for now (or at least any shell relying on
`complete` and `compgen`).

For `bash`, run:
    $ xan completions bash >> ~/.bashrc

To enable those completions system-wide, you can also run:
    $ xan completions bash > /etc/bash_completions.d/xan

For `zsh`, run:
    $ xan completions zsh >> ~/.zshrc

You will need to reload you shell or source your main shell
configuration file (`source ~/,bashrc` for bash, for instance) for
the completions to be activated (this is only required once).

Usage:
    xan completions (bash | zsh)
    xan completions --help

Common options:
    -h, --help             Display this message
