//! The `scan` subcommand: scans the filesystem for git repos.
//!
//! By default, the user's home directory is walked, but this starting point can
//! be configured in `~/.gitconfig`:
//!
//! ```bash
//! $ git config --global global.basedir /some/path
//! ```
//!
//! The `scan` subcommand caches the list of git repos paths it finds, and can
//! be rerun at any time to refresh the list.
