+(FTP)
+When listing an FTP directory, this switch forces a name-only view. This is
+especially useful if the user wants to machine-parse the contents of an FTP
+directory since the normal directory view doesn't use a standard look or
+format. When used like this, the option causes a NLST command to be sent to
+the server instead of LIST.
+
+Note: Some FTP servers list only files in their response to NLST; they do not
+include sub-directories and symbolic links.
+
+(POP3)
+When retrieving a specific email from POP3, this switch forces a LIST command
+to be performed instead of RETR. This is particularly useful if the user wants
+to see if a specific message id exists on the server and what size it is.
+
+Note: When combined with --request, this option can be used to send an UIDL
+command instead, so the user may use the email's unique identifier rather than
+it's message id to make the request.
