Don't confuse ftps with ftp-ssl--at least when it comes to curl, the former
implies an implicit SSL connection upon socket connection (this is almost
always on port 990), whereas the latter uses a clear text initial ftp
connection with negotiation of SSL afterward (on port 21). Most ftp servers
supporting SSL these days are the latter, which means curl expects a
the --ftp-ssl option on a ftp:// URL, not an ftps:// one.
