|

|
|
9 | This module implements protocol extensions for use by the CF+ client, but |
|
|
10 | can be used by other clients as well. It uses the C<extcmd> mechanism |
|
|
11 | exclusively. |

17 | Registers the client the the server. the client should send the highest |
|
|
18 | version of the protocol it supports itself, and the server returns the |
|
|
19 | highest version of the protocol it supports in the C<version> key itself. |
