  Hmmm. I don't know enough about libcurl and ftp to answer this
question, but as far as I understand the ftp rfc this would be enough to
handle a "command only" behaviour.

  If we use this approach, I would have to add

curl_easy_setopt (curl, SKIP_PASV, TRUE);
curl_easy_setopt (curl, SKIP_RETR, TRUE);

  and do all the other stuff as I do it now, right? That's absolutely
okay for me, but I can't see a big difference between this and my former
suggestion. In both ways you have the option to do:

1. Only transmit commands.

2. Work through a pre download/upload command list, do the
download/upload and do some commands after that.

  Please explain the difference of the two approaches. I can't see a real
difference - but, I said that, I'm not experienced with ftp or curl or
