[Evolution] can anyone tell me

[maestro <waggawagga gmx net>]

how to learn about evolution at a source code level, (yes i know i've
got to read the sourcecode, but is there anything else helpful to get in
touch with this software like documentation or stuff like that?)
i'm tired of asking about the "group by this field" feature so i decided
to give it a try to implement it on my own.

thanks a lot
me
