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 z6MknSL…StBU8Vi..
✓ Creating checkout in ./Developer/Radicle..
✓ Remote alice@z6MknSLrJoTcukLrE435hVNQT4JUhbvWLX4kUzqkEStBU8Vi added
✓ Remote-tracking branch alice@z6MknSLrJoTcukLrE435hVNQT4JUhbvWLX4kUzqkEStBU8Vi/master created for z6MknSL…StBU8Vi
✓ Repository successfully cloned under [..]/Developer/Radicle/

```

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
✓ Fetching rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji from z6MknSL…StBU8Vi..
✗ Error: the directory path "Developer/Radicle" already exists
