[rsyslog] How to add new configuration option

[Tomas Kubina]

Hi,

I would appreciate any help with adding support for a new configuration 
directive. I have done some
code and I need now something like:
$AddClientCN [on/off].
I have read the sources to find out how rsyslog processes conf file. 
There is some linked list with
known commands. I think that it is enough to add new item to this list 
but I don't know how.
Is this my idea right?

Thanks for any help.

Regards,

Tomas
