[Telepathy] Request for "Hello World" program for XMPP-Link-Local

[Ajay Garg]

Ping :)

Danielle, just wanted to let you know that I have managed to run a
telepathy-salut "Hello World" program (discovering buddies
coming-online/going-offline), using Python-Binding.

I just need to try it using native C bindings, as C is supposedly the
fastest system-programming language.

Sorry to bother you, but I am still stuck at the third stage (using C
binding).



Regards,
Ajay
