=head1 CF+ protocol extensions |
| 8 |
|
| 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. |
