Access to the development-source-tree of gtk ?

[Daniel Adler <dadler gwdg de>]

Hi all gtk-developers,

how can i get access to the development-source-tree of gtk ?

I am interessted in the newest features, and i have got a lot of ideas.
Especially I'm thinking of customization-mechanisms built in some
widgets, so that every user can easyly start up a property-editor or
big config-screens.
Well, I only want to see how far you guys are going at the moment,
perhaps I can help.
