What is the IRC info for this?  I'd like to monitor it.

Thanks,

Hello all,

There is a misanderstanding with Bertil on my holidays.
I'm happy to tell that I'm back to the office this week.

And I have 8 hours scheduled this week to help for the vector
integration (answering questions, helping anderstanding the code, etc
...).

Don't hesitate to ask. I'll be available on the IRC channel, and also
on google talk (pierre dot giraud at gmail dot com, bluecarto at gmail
dot com)

Regards

Pierre
