48 | * The Direct Connect protocol is extremely ugly. Thus, this code must | |
49 | * also be a bit ugly in certain places. Please forgive me. =/ | |

51 | * This also means that there might be some pieces of the code that | |
52 | * look completely illogical to you, and you think that you may make | |
53 | * them much neater/better. However, in many cases it might just be | |
54 | * that it's required to cope with some oddity of the protocol, such | |
55 | * as the amazingly ugly delayed key response in the peer protocol. | |
