evolution extensions

[David Roguin <nesdavid@gmail.com>]

Hi,

I want to make an evolution extension that adds a simple 'archive'
button that mimics the gmail's one.

I have a doubt about what evolution source should I change. I'm using
wheezy right now, so most of my gnome packages are 3.2.* even though
gnome's master is in 3.3.
What I was thinking is getting evolution src from debian, make changes
and build the package again. Instead of getting the latest evolution
from upstream.

What do you recommend?

Thanks in advance.

ps: I don't even know if I should be asking this kind of question in
this mailing list.
