We can specify where a repository gets cloned into on our filesystem
by specifying the directory in the `rad clone` command:

```
$ rad clone rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji --scope followed Developer/Radicle
✓ Seeding policy updated for rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji with scope 'followed'
Fetching rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji from the network, found 1 potential seed(s).
✓ Target met: 1 seed(s)

Run `cd [..]/Developer/Radicle` to go to the repository directory.
```

Note that attempting to clone into a directory that already exists,
and is not empty, will fail:

``` (fail)
$ rad clone rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji --scope followed Developer/Radicle
✗ Error: refusing to checkout repository to Developer/Radicle, since it already exists
✗ Hint: try `rad checkout rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji` in a new directory
✗ Error: failed to clone rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji
