63b1700f | 6 | FTP Aquire Method - This is the FTP aquire method for APT. |
30b30ec1 AL |
7 | |
8 | This is a very simple implementation that does not try to optimize | |
9 | at all. Commands are sent syncronously with the FTP server (as the | |
10 | rfc recommends, but it is not really necessary..) and no tricks are | |
11 | done to speed things along. | |
