[leafnode-list] How to modify what leafnode offers through XOVER ?

[Xavier Maillard]

Hello,

I tried to see what the overview on the server offered and I saw
this:

,----
| % telnet 10.0.0.4 nntp                                                                                                                                   [1.12 1.11 - 57% 11%]

How can I add other stuff (NNTP-..., keywords, ...) ?

[P.S: no need to tell which version I am running ;)]
