IFTPShell is the way you control the behavior of the FTP server. To exclude
certain results from a directory listing, you would implement the `list´
method so that it has the necessary logic for performing that exclusion.

You found an implementation of a realm which supports IFTPShell. If you
aren't familiar with realms, read the cred documentation:
The realm is important but pretty simple. The avatar, the IFTPShell
implementation, is what really controls the behavior you're interested
